How Much Money Do You Need to Start Day Trading?
There are two answers: the minimum a broker or regulator will let you open, and the amount your own risk plan needs to make sense. They are rarely the same number, and the second one is the useful one.
There are two numbers: the minimum the rules impose, and the amount your risk plan needs. In the US, four or more day trades in five business days in a margin account requires $25,000 of equity under FINRA's pattern day trader rule. Forex, futures and evaluation accounts start far lower. Work backwards from the smallest sensible loss per trade.
What account size does your risk plan need?
Account = smallest sensible loss ÷ risk %. The streak line compounds that risk on a shrinking balance. This is arithmetic about sizing, not a suggestion that any amount makes trading likely to pay.
The rule-based minimums
- US stocks and options. If you place four or more day trades in five business days in a margin account, FINRA's pattern day trader rule requires the account to hold at least $25,000 in equity. Cash accounts avoid the rule but settle trades over days, which limits how often you can recycle the same money. Check the current rule with your broker - regulations change.
- Forex and CFDs. Many brokers open accounts for very small deposits. Leverage caps differ by jurisdiction, and a low minimum says nothing about whether the amount is workable.
- Futures. Brokers set day-trade margins per contract, and micro contracts lowered the entry point considerably. Margin is what you must post, not what you can afford to lose.
- Evaluation (prop) accounts. You pay a fee for a simulated account with rules. That is a different product from trading your own capital - see the challenge guide.
The number that actually matters
Work backwards from risk instead of forwards from hope. Pick the smallest loss per trade that still lets you take normal setups on the instrument you trade, decide what percentage of the account that loss is allowed to be, and the account size falls out. The calculator above does exactly that, and it also shows what a normal losing streak looks like at that size.

With too little capital, the smallest position the market allows is already a large percentage of the account. Every trade becomes high-stakes, ordinary losing runs feel catastrophic, and the behaviour that follows - sizing up to catch up, skipping stops - does the real damage. The risk of ruin calculator shows the same thing in numbers.

Frequently asked questions
How much money do I need to day trade stocks in the US?
If you make four or more day trades in five business days in a margin account, FINRA's pattern day trader rule requires at least $25,000 of equity. A cash account avoids the rule but settlement limits how often you can reuse funds.
Can I start day trading with $100?
Some brokers will open an account, but $100 rarely supports sensible position sizing, and the smallest tradeable size is usually a large share of the balance. Practising free first costs nothing.
Is more capital safer?
It makes proportional sizing easier, which is a real advantage. It does not create an edge, and it is not a reason to expect profit.
What about prop firm accounts?
You pay a fee for a rules-based simulated account. It lowers the capital needed but adds rules that most attempts fail on.
