Prop firm pass rate calculator
Enter your win rate, how much a winner makes compared with what a loser costs, and what you risk on each trade. Pick a firm and an account size. The calculator plays 4,000 attempts of that evaluation under the firm's real rules and tells you how many pass, what ends the ones that fail, and how long a pass takes.

How it worksHow the prop firm pass rate is calculated
Your numbers, trade by trade
Each trade wins with your win rate and pays your reward to risk, or loses one risk. Trades come in random order, a few a day, the way a run of luck or bad luck really arrives.
The firm's real rules
Profit target, maximum loss and daily loss come from the firm's published rules, checked and dated on each firm page. The maximum loss follows the firm's type: fixed, trailing at the end of each day, or trailing during the day, stopping at the starting balance where the firm says so.
4,000 attempts
The same evaluation is played 4,000 times. The pass rate is the share that reached the target without breaking a rule. The same inputs always give the same answer.
What the calculator leaves out
It is a model of your numbers, not of your trading. Real trading is harder in ways it cannot see:
- Every trade is a full win or a full loss: no partial exits, no breakeven stops, no slippage.
- The trailing drawdown is checked when each trade closes. A trade that runs up and then stops out raises a real intraday floor more than this does.
- A consistency rule is reported, not enforced: the result says how often one day carried the pass.
- Losing streaks change how people trade. The calculator never revenge trades; people do.
Prop firm pass rate questions
How is the pass rate calculated?
The calculator plays the evaluation 4,000 times. In each attempt, trades win or lose at random with your win rate and reward to risk, a few a day, and the firm's profit target, maximum loss and daily loss decide when the attempt ends. The pass rate is the share of attempts that reached the target without breaking a rule.
Why does risk per trade change the odds so much?
The target and the maximum loss are fixed amounts. Risking more reaches the target in fewer winners, but a normal losing streak also reaches the maximum loss sooner. For most traders with a modest edge, the pass rate rises as risk per trade falls, until the time it takes starts to matter. The chart under the result shows this for your numbers.
Why is a trailing drawdown harder to pass?
A static maximum loss sits at a fixed distance below the starting balance. A trailing one moves up behind your best equity, so money you made and gave back still counts against you. Most futures firms trail, either at the end of each day or during the day, and many stop the trail once it reaches the starting balance.
Does it include the consistency rule?
It reports it. Firms such as Topstep, Take Profit Trader and Tradeify limit how much of the profit one day can make. When the firm has such a rule, the result says how many of the passes had one day above it. Those traders would usually need more days before the firm signs them off.
Where do the firm rules come from?
From each firm's own published rules, checked by hand and dated on that firm's page in the prop firm simulator. Firms change their rules, so check the firm's current rules before you buy anything.
Can I use my real trading results instead?
Yes, in the app. Practice a challenge on real market history, and the session's page runs the same kind of pass check on your own daily results, not on numbers you typed in.

Hypothetical or simulated performance results have certain limitations. Unlike an actual performance record, simulated results do not represent actual trading. Also, since the trades have not been executed, the results may have under- or over-compensated for the impact, if any, of certain market factors, such as lack of liquidity. Simulated trading programs in general are also subject to the fact that they are designed with the benefit of hindsight. No representation is being made that any account will or is likely to achieve profit or losses similar to those shown.
