Cash Account vs Margin Account: What Beginners Need to Know
A cash account only lets you trade with money you’ve deposited. A margin account lets you borrow money from your broker to take larger positions. Beginners should start with a cash account in most cases. Margin amplifies both gains and losses, and the added complexity creates traps that new traders aren’t ready for.
How Cash Accounts Work
With a cash account, you trade exclusively with your own money. If you deposit $5,000, you can buy up to $5,000 worth of stock. Once you sell, the cash takes one to two business days to settle (called T+1 or T+2 settlement) before you can use it again.
The main advantage: you can never lose more than what’s in your account. There are no margin calls, no interest charges, and no risk of your broker liquidating your positions. Cash accounts also aren’t subject to the Pattern Day Trader rule, so you can day trade with less than $25,000, though settlement times will limit how frequently.
The downside is less buying power and the settlement delay. If you sell a stock today, you might not be able to use that cash to buy something else until tomorrow or the day after.
How Margin Accounts Work
A margin account lets you borrow funds from your broker, typically up to 2:1 for stocks (so $5,000 in cash gives you $10,000 in buying power). For futures, the leverage is much higher, sometimes 10:1 or more.
This extra buying power can boost your returns, but it also magnifies your losses. If you buy $10,000 worth of stock on margin and it drops 10%, you’ve lost $1,000, which is 20% of your actual $5,000 deposit.
Margin calls are the real danger. If your account value drops below the broker’s maintenance requirement (usually 25-30% of your position value), you’ll be forced to deposit more money or your broker will sell your positions automatically, often at the worst possible time.
Margin accounts also trigger the PDT rule. If you make four or more day trades within five business days, you’ll be flagged as a Pattern Day Trader and must maintain $25,000 in your account.
Which Should You Choose?
Start with a cash account if:
- You’re brand new to trading
- Your account is under $25,000
- You want to avoid the PDT rule
- You prefer simpler risk management
Consider a margin account if:
- You have $25,000+ and want to day trade stocks actively
- You understand leverage and risk management
- You’ve been trading profitably in a cash account or paper trading for several months
For most beginners, a cash account is the safer choice. Once you have a track record and understand your risk tolerance, upgrading to margin makes sense. Learn more about responsible trading approaches in our education section.

Frequently Asked Questions
Can I switch from a cash account to a margin account? Yes. Most brokers let you upgrade your account type at any time. You’ll typically need to sign additional risk disclosures. Downgrading back to cash is also possible.
Do I pay interest on margin? Yes. Borrowing on margin costs interest, typically 5% to 12% annually depending on your broker and loan amount. This cost eats into your profits, especially on longer-term positions.
Can I lose more than my deposit with a margin account? Yes. In extreme market conditions, your losses can exceed your deposit. You’d then owe money to your broker. This is rare but has happened during flash crashes and overnight gaps.
