Margin Account vs. Cash Account: Key Differences Explained

The main difference between a margin account and a cash account is borrowing. A cash account requires you to pay the full purchase price of your investments, while a margin account may allow you to borrow money from your brokerage firm using eligible securities as collateral.

Borrowing can increase your purchasing power, but it can also magnify losses, generate interest charges, and allow your broker to sell investments without consulting you first.

For many beginner and long-term investors, a cash account offers a simpler way to invest because it avoids margin debt and margin calls. A margin account may provide greater flexibility for experienced investors, but its additional features come with substantial financial risks.

This margin account vs. cash account comparison explains how each account works, their costs and trading restrictions, and the questions to consider before choosing one.

What Is a Cash Account?

A cash account is a brokerage account in which you must pay the full purchase price of the securities you buy.

If you want to purchase $5,000 of stock in a cash account, you generally need enough cash or eligible settled funds to complete the transaction. Your broker does not lend you the remaining money.

The U.S. Securities and Exchange Commission’s cash-account guidance explains that an investor using a cash account cannot borrow funds from the broker-dealer to pay for securities transactions.

A cash account may allow you to buy:

Stocks
Exchange-traded funds
Mutual funds
Bonds
Treasury securities
Certificates of deposit available through the brokerage
Certain options strategies, subject to approval
Other investments supported by the broker

The exact investments and trading features depend on the brokerage firm.

What Is a Margin Account?

A margin account is a brokerage account that may allow you to borrow money from your broker to purchase eligible securities.

Your cash and securities serve as collateral for the loan. The broker charges interest on the amount borrowed, and you must maintain a required amount of equity in the account.

The SEC defines a margin account as an account in which a broker-dealer lends an investor cash, using the account as collateral, to purchase securities. Margin can increase purchasing power, but it also exposes the investor to larger potential losses.

Suppose you deposit $10,000 in a margin account. Subject to regulatory requirements, the broker’s policies, and the eligibility of the investment, you may be able to purchase up to $20,000 of marginable securities by borrowing the remaining $10,000.

You remain responsible for repaying the loan, interest, and other charges regardless of whether the investment rises or falls.

Margin Account vs. Cash Account: Quick Comparison

Feature	Cash account	Margin account
Borrowing from broker	Not permitted	Permitted for eligible transactions
Purchase amount	Limited to available cash or settled funds	May exceed deposited cash
Interest charges	No margin-loan interest	Interest charged on borrowed funds
Potential losses	Generally limited to invested amount, excluding certain advanced products	May exceed the cash initially deposited
Margin calls	No	Yes
Forced liquidation	Not caused by a margin loan	Broker may sell securities without prior consultation
Short selling	Generally unavailable	May be available with approval
Settlement management	Important to avoid cash-account violations	Margin may provide more settlement flexibility
Complexity	Lower	Higher
Typical user	Beginner or long-term investor	Experienced investor who understands leverage
Main risk	Market losses and settlement violations	Magnified losses, interest, margin calls, and forced sales

Neither account protects you from normal investment losses. The important difference is that a margin account adds borrowing and collateral-related risks.

How Buying Power Differs

Buying Power in a Cash Account

Your buying power is generally based on the cash and eligible settled funds available in the account.

If you deposit $10,000, you can normally purchase up to $10,000 of investments. You cannot borrow another $10,000 from the brokerage to double the position.

Proceeds from a recent sale may appear as available buying power before settlement, but using those proceeds incorrectly can lead to a cash-account trading violation.

Buying Power in a Margin Account

Margin may allow you to purchase more securities than you could buy with cash alone.

Under the Federal Reserve Board’s Regulation T, a broker can generally lend up to 50% of the purchase price of eligible margin equity securities for a new purchase. Brokerage firms may impose stricter requirements, and some securities are not marginable.

FINRA’s margin regulation guidance explains that brokers can generally lend a customer up to 50% of the total purchase price of a margin equity security under Regulation T.

That does not mean every investor or security qualifies for the maximum amount. A brokerage may require a larger cash contribution based on:

The security being purchased
Market volatility
Concentration in one position
The investor’s account history
The broker’s internal risk policies

Increased buying power also means increased exposure to price movements.

Cash vs. Margin Account Example

Assume two investors each have $10,000.

Investor A: Cash Account

Investor A uses $10,000 to purchase stock.

If the stock rises by 25%, the position becomes worth $12,500. The gain is $2,500, excluding taxes, commissions, and other costs.

If the stock falls by 25%, the position becomes worth $7,500. The loss is $2,500.

Investor B: Margin Account

Investor B contributes $10,000 and borrows another $10,000 to purchase $20,000 of the same stock.

If the stock rises by 25%, the position becomes worth $25,000. After subtracting the $10,000 loan, the investor has $15,000 of equity—a $5,000 gain before margin interest and other costs.

If the stock falls by 25%, the position becomes worth $15,000. After subtracting the $10,000 loan, only $5,000 of equity remains—a $5,000 loss.

Result	Cash account	Margin account
Investor’s starting cash	$10,000	$10,000
Initial investment position	$10,000	$20,000
Position after a 25% gain	$12,500	$25,000
Equity after repaying margin loan	$12,500	$15,000
Gain before costs	$2,500	$5,000
Position after a 25% loss	$7,500	$15,000
Equity after subtracting loan	$7,500	$5,000
Loss before costs	$2,500	$5,000

This simplified example shows how leverage can magnify gains and losses. It excludes margin interest, taxes, fees, changing margin requirements, and forced liquidation.

What Is Margin Interest?

Margin interest is the cost of borrowing money from a brokerage firm.

The interest rate may depend on:

The broker
The amount borrowed
A reference or base rate
Current interest-rate conditions
The investor’s relationship with the firm
Promotional or negotiated pricing

Interest generally accrues while the loan remains outstanding. Even if an investment does not change in value, margin interest reduces the investor’s return.

For example, suppose an investment produces a 6% gain while the effective borrowing cost is 10%. The investment may increase in value, but the financing cost can consume the gain and create a net loss on the borrowed portion.

Margin rates can change. Review the broker’s current rate schedule and understand how interest is calculated and posted before borrowing.

What Is a Margin Call?

A margin call occurs when the equity in a margin account falls below a required level.

Account equity is generally calculated as:

Account equity = Current market value of securities − Amount owed to broker

FINRA rules generally require at least 25% maintenance equity for long marginable stocks. However, a broker can establish a higher “house” requirement, such as 30% or 40%, and may raise that requirement when market conditions or the risk of a position changes.

According to FINRA’s margin-call guidance, firms may impose maintenance requirements above the regulatory minimum and can increase their house requirements without providing advance written notice.

If your equity falls below the applicable requirement, the broker may demand that you:

Deposit additional cash
Deposit eligible securities
Reduce the borrowed balance
Sell part of the position

A margin call is not a request that you can safely ignore. If you do not meet it—or if the broker decides immediate action is necessary—the firm may liquidate securities in the account.

Can a Broker Sell Your Investments Without Permission?

Yes. A margin agreement can give the brokerage firm the right to sell securities in your account when necessary to satisfy a margin deficiency.

Important risks include:

The broker may sell investments without contacting you first.
You may not be able to choose which securities are sold.
The firm may sell a security that you intended to hold long term.
A sale can occur during a market decline.
The transaction may create taxable gains or losses.
You remain responsible for any deficit after liquidation.

The broker’s priority is protecting the loan, not waiting for your investment to recover.

This makes margin especially dangerous for concentrated or volatile portfolios. A temporary price decline can cause a forced sale before the market rebounds.

Initial Margin vs. Maintenance Margin

These two requirements apply at different stages.

Initial Margin

Initial margin determines how much of a new purchase you must fund yourself.

Under Regulation T, an investor can generally borrow up to 50% of the purchase price of eligible margin securities. The broker may require more.

Before trading on margin, FINRA generally requires a minimum deposit of $2,000 or 100% of the purchase price of the margin securities, whichever is less. Firms may impose higher minimums.

Maintenance Margin

Maintenance margin is the minimum equity that must remain in the account after the purchase.

FINRA’s minimum is generally 25% of the current market value of long margin securities, although brokers commonly impose higher house requirements.

For example, assume:

Current securities value: $20,000
Margin loan: $10,000
Account equity: $10,000
Equity percentage: 50%

If the securities fall to $13,000 while the loan remains $10,000:

Account equity: $3,000
Equity percentage: approximately 23.1%

That would fall below a 25% maintenance requirement and could produce a margin call. A higher house requirement could trigger a call before the account reaches that level.

How Settlement Works in a Cash Account

Most U.S. transactions in stocks, exchange-traded funds, corporate bonds, municipal securities, and certain other securities now settle one business day after the trade date, commonly called T+1.

If you buy an investment on Monday, settlement will generally occur on Tuesday, assuming neither day is a market holiday.

The SEC’s T+1 settlement guidance explains that investors may need to pay for purchases one business day earlier than under the former T+2 cycle.

Settlement rules matter in a cash account because the investor must pay for each purchase in full. Trading with unsettled sale proceeds can be permitted in some situations, but selling the newly purchased security before the original funding sale settles may create a violation.

Your brokerage’s interface may display unsettled funds as buying power. That display does not remove the responsibility to follow cash-account settlement rules.

Good-Faith Violations in Cash Accounts

A good-faith violation can occur when you purchase a security using proceeds from a sale that has not yet settled and then sell the newly purchased security before the original sale settles.

Example:

You sell Stock A on Monday.
The sale is scheduled to settle on Tuesday.
You use those unsettled proceeds to purchase Stock B on Monday.
You sell Stock B before the sale of Stock A settles.

Because Stock B was purchased with unsettled proceeds and sold before those funds settled, the transaction may result in a good-faith violation.

FINRA’s intraday-trading guidance advises that purchasing a security with unsettled proceeds and selling it before the funding transaction settles can create a good-faith violation.

Broker policies can differ, so review the firm’s cash-account trading rules and pay attention to settlement warnings.

What Is Freeriding?

Freeriding generally occurs when an investor buys a security and then uses proceeds from selling that same security to pay for its purchase.

For example:

You purchase $5,000 of stock without having enough available cash to pay for it.
Before depositing the required money, you sell the stock.
You attempt to use the sale proceeds to cover the original purchase.

The SEC states that freeriding is prohibited under Regulation T and may cause a broker to freeze the cash account for 90 days. During the freeze, purchases must generally be fully paid for on the trade date with available funds.

Freeriding is different from an ordinary investment loss. It is a payment and settlement violation.

Advantages of a Cash Account

No Margin Debt

You are not borrowing from the brokerage, so there is no margin loan to repay.

No Margin Interest

Investment returns are not reduced by interest charged on borrowed brokerage funds.

No Margin Calls

Market declines can reduce your investment value, but they do not create a margin call based on a brokerage loan.

Lower Risk of Forced Liquidation

The broker does not need to sell investments to protect a margin loan. Other account rules or legal circumstances may still permit restrictions or liquidation, but ordinary market losses alone do not create a margin deficiency.

Simpler Risk Management

Your purchasing power is generally limited to the money available in the account, making leverage-related losses easier to avoid.

Suitable for Many Long-Term Investors

Investors regularly buying diversified investments and holding them for long periods may not need margin borrowing.

Disadvantages of a Cash Account

Lower Buying Power

You can invest only the money available rather than borrowing against the account.

Settlement Rules Require Attention

Trading rapidly with unsettled proceeds can lead to good-faith violations, freeriding, or account restrictions.

Short Selling Is Generally Unavailable

Short selling typically requires a margin account because the investor must borrow securities.

Some Strategies May Be Restricted

Certain options or advanced trading strategies may require margin approval, depending on the broker and the strategy.

Less Short-Term Flexibility

A margin account may allow eligible investors to trade or access funds without waiting for sale proceeds to settle, but that flexibility comes with borrowing risk and potential interest.

Advantages of a Margin Account

Greater Purchasing Power

Borrowing may allow you to purchase more securities than your cash balance alone would permit.

Trading Flexibility

Margin may provide access to unsettled funds under the brokerage’s rules and reduce some cash-account settlement limitations.

Access to Short Selling

Short sales generally require a margin account and additional approval.

Access to Certain Advanced Strategies

Some options and trading strategies require margin privileges, appropriate approval, and sufficient account equity.

Potential Liquidity

Some investors borrow against eligible securities instead of selling them. However, interest, market risk, margin requirements, and tax considerations must be evaluated carefully.

Disadvantages of a Margin Account

Magnified Losses

Leverage increases exposure. A market decline can produce a loss much larger than it would in a cash-only position.

Losses Can Exceed Your Initial Deposit

If securities fall sharply and liquidation proceeds do not cover the loan, you may owe the brokerage additional money.

Interest Reduces Returns

Margin interest accrues regardless of whether the investment makes money.

Risk of Margin Calls

Falling security prices or higher house requirements can create an immediate demand for more equity.

Forced Liquidation

Your broker may sell securities without consulting you and may choose which positions to liquidate.

Changing Requirements

A brokerage may increase the margin requirement for a volatile, concentrated, or low-priced security.

Added Complexity

Investors must monitor equity, loan balances, interest rates, buying power, and maintenance requirements.

Cash Account vs. Margin Account for Beginners

A cash account is generally the simpler option for a beginner because it prevents borrowing from the broker and eliminates margin calls.

A beginner can still lose money when investments decline, but the account does not amplify an ordinary stock purchase through a margin loan.

A margin account should not be selected merely because it displays higher buying power. Before enabling margin, an investor should understand:

How margin interest is calculated
When a margin call can occur
The broker’s house requirements
Which securities are marginable
How forced liquidation works
Whether losses could exceed the initial deposit
How much volatility the investor can tolerate

Your decision should align with your investment risk tolerance. If a temporary market decline would cause financial stress or force you to sell investments, borrowing to increase exposure may not be appropriate.

Cash Account vs. Margin Account for Long-Term Investing

A cash account is often sufficient for an investor who regularly contributes money, buys diversified investments, and holds them for long-term goals.

Margin is not necessary to:

Purchase stocks or ETFs
Reinvest dividends
Build a diversified portfolio
Use dollar-cost averaging
Save for retirement in a taxable brokerage account

Using debt to invest introduces a financing cost and increases the chance that a market decline disrupts a long-term plan.

Before investing—whether through a cash or margin account—maintaining an emergency fund and following a realistic savings plan can reduce the likelihood that you will need to sell investments during an unexpected expense.

Can You Lose More Than You Invest in a Cash Account?

With a straightforward fully paid purchase of stocks or funds, your loss is generally limited to the amount invested if the security falls to zero.

However, some products and strategies may create additional obligations. Options, short positions, futures, and other complex instruments can carry different risks. A product should not be assumed safe merely because it is held through an account described as a cash account.

Review the risk disclosure for the specific investment and strategy.

Can You Lose More Than You Invest in a Margin Account?

Yes. A margin account can produce losses exceeding the cash you initially deposited.

Suppose you contribute $10,000, borrow $10,000, and purchase $20,000 of stock. If the position falls sharply and is sold for less than the outstanding loan plus interest and fees, you may have a deficit.

The brokerage can require you to pay that remaining balance.

Fast-moving markets can make this worse. Prices may fall more quickly than you can deposit funds or sell voluntarily.

Does Opening a Margin Account Affect Your Credit?

Brokerage firms generally focus on your financial information, investment experience, and account eligibility when reviewing a margin application. Practices can vary, and a firm may conduct identity, credit, or other checks permitted under its policies.

A margin loan is different from a traditional credit card or personal loan. Do not assume its activity will appear on standard consumer credit reports or build your credit score.

Read the broker’s disclosures and privacy notice to understand what information it may obtain or share.

Does a Margin Account Mean You Must Borrow?

No. Having margin privileges does not necessarily mean that you are currently borrowing.

You may hold fully paid securities in a margin-enabled account without maintaining a margin loan. However, certain transactions, withdrawals, or trading activity may create a margin debit.

Check the account’s balances carefully. Terms such as “buying power,” “cash available to withdraw,” and “margin balance” can mean different things. If you are unsure whether a transaction will create interest-bearing debt, confirm with the broker before proceeding.

Questions to Ask Before Opening a Margin Account

Ask the brokerage:

What is the current margin interest rate?
Is the rate variable, and how is it calculated?
What is the minimum initial deposit?
What are the standard house maintenance requirements?
Which securities carry higher requirements?
Can requirements change without advance notice?
When can the firm liquidate positions?
Will the firm attempt to contact me before selling?
How are margin calls communicated?
Which positions can the firm choose to sell?
What happens if liquidation leaves a deficit?
What fees apply in addition to interest?

Read the full margin agreement rather than relying only on the buying-power figure displayed by the trading platform.

How to Choose Between a Margin and Cash Account

A cash account may be more appropriate if you:

Are a beginner
Want to avoid borrowing
Invest primarily for long-term goals
Do not need short selling
Prefer simpler account management
Do not want margin interest or margin calls
Are willing to manage settlement timing

A margin account might be considered if you:

Fully understand leverage and forced liquidation
Need a feature that requires margin
Can monitor the account closely
Have sufficient financial reserves
Can withstand losses exceeding your initial cash
Understand the broker’s interest rates and house rules
Have carefully evaluated whether the benefit justifies the risk

Being eligible for margin does not mean using margin is suitable. The correct choice depends on your finances, investment goals, experience, time horizon, and capacity for loss.

Frequently Asked Questions

Is a cash account safer than a margin account?

A cash account avoids margin loans, interest, margin calls, and leverage-related forced liquidation. It still carries the market risk of the investments you select.

Is a margin account better than a cash account?

Not automatically. Margin offers more purchasing power and trading flexibility, while a cash account is simpler and avoids borrowing. The better choice depends on your strategy and ability to manage risk.

Can I switch from a margin account to a cash account?

Brokerages commonly allow eligible account-type changes, but you may first need to repay margin debt, close unsupported positions, or wait for trades to settle. Ask your broker about its process.

Can I have both a cash account and a margin account?

Many investors can maintain separate accounts, subject to the brokerage’s eligibility requirements. Keeping them separate may make it easier to distinguish cash-only investments from leveraged activity.

Do cash accounts have margin calls?

No. A standard cash account does not involve a margin loan, so it does not generate a margin call. Cash-account settlement violations and other restrictions can still occur.

Can you day trade in a cash account?

You may trade frequently in a cash account, but every purchase must comply with payment and settlement rules. Reusing unsettled funds incorrectly can create violations.

Can you short stocks in a cash account?

Short selling generally requires a margin account because the shares must be borrowed before they are sold.

Are all stocks marginable?

No. Brokerages may exclude certain securities or impose higher requirements based on price, volatility, liquidity, concentration, and other risks.

What is the minimum maintenance margin?

FINRA’s general minimum for long marginable stocks is 25% of their current market value. A broker may require 30%, 40%, or more and may apply different requirements to particular securities or accounts.

Does margin interest apply if I do not borrow?

Generally, margin interest applies to an outstanding margin debit rather than simply having a margin-enabled account. Confirm how your broker treats withdrawals, unsettled activity, and account balances.

What happens if I cannot meet a margin call?

The broker may sell securities in your account. If the liquidation proceeds do not fully repay the loan, interest, and charges, you may still owe money.

Final Thoughts

The central difference in the margin account vs. cash account decision is whether you can borrow from your brokerage.

A cash account requires you to pay the full purchase price of your investments. It avoids margin interest and margin calls, making it a simpler choice for many beginners and long-term investors. You must still understand settlement timing and avoid good-faith and freeriding violations.

A margin account can provide more purchasing power, short-selling access, and trading flexibility. However, it can magnify losses, charge ongoing interest, trigger margin calls, and allow the broker to liquidate securities without your approval.

Before enabling margin, read the brokerage agreement, compare interest rates and house requirements, and consider whether borrowing aligns with your financial position and tolerance for loss. If you do not clearly need a margin feature, a cash account may provide everything required for a straightforward long-term investment strategy.
