The Math

How the Expected Value Is Calculated

First find the gross profit you'd make before a payout: account size times your profit target. Multiply that by the split you keep to get your payout. The expected value weighs that payout by your odds of passing, then subtracts the fee you pay either way — because the fee is spent whether you pass or fail.

Share = Account × Target% × Split% | EV = (Pass% × Share) − Fee Example: $100,000 × 8% = $8,000 gross. At an 80% split, your share = $6,400. EV at 30% = (0.30 × $6,400) − $500 = $1,420. Break-even pass rate = $500 ÷ $6,400 = 7.8%.

Quick Reference

Terms In This Calculator

Concept	What it means
Expected value	The average outcome weighted by your pass odds — what one attempt is worth on average.
Break-even pass rate	The pass percentage where expected value equals zero. Above it the math favours you; below it, it doesn't.
Note	Many firms refund the challenge fee on the first payout, which improves the real expected value.

Frequently Asked Questions

Is a prop challenge worth the fee?

It depends on your honest pass odds and the split. A challenge has positive expected value only when your chance of passing clears the break-even pass rate this tool shows. Be realistic: most traders overestimate their odds, and the fee is spent whether you pass or fail.

What is expected value here?

It's the average result of taking this challenge many times, weighting your payout by your odds of passing and subtracting the fee you always pay. A positive figure means the attempt pays off on average; a negative one means the fee outweighs the expected payout.

What pass rate breaks even?

The break-even pass rate is the fee divided by the payout you'd keep. In the default example, a $500 fee against a $6,400 share breaks even at 7.8%. Pass more often than that and the math favours you; pass less often and you lose money over time.

Is the fee refundable?

Many firms refund the challenge fee on your first payout, but not all do, and a failed attempt is rarely refunded. This tool treats the fee as a cost you pay either way. If your firm refunds it on success, your real expected value is a little better than the figure shown.

Fee vs payout

Prop Firm ROI Calculator to Weigh the Fee Against Your Payout

A prop firm ROI calculator helps you decide whether a challenge is worth paying for before you buy in. You weigh the challenge fee against the payout you would actually keep and your honest odds of passing, and it returns the expected return of one attempt along with the break-even pass rate. The default example starts from a $500 fee and a $100,000 account. Because the fee is spent whether you pass or fail, the answer is as much about probability as about cost. It is free and browser-based, and trading carries risk of loss, so a positive result is an average, not a promise.

Fee either way

Pass or Fail, the Prop Firm Challenge Fee Is Spent Either Way

Pass or fail, you pay the challenge fee up front, and that one fact shapes the whole return. In the default example a pass turns the $500 fee into a $6,400 payout share you keep, while a fail leaves the same $500 spent and no share at all. The attempt therefore nets the share minus the fee when you pass and only the lost fee when you fail, and your pass odds decide which outcome weighs more. Be realistic about those odds, because most traders overestimate them, and remember that trading carries risk of loss before any payout arrives.

Expected value

Expected Value of a Prop Firm Challenge in Three Numbers

Expected value is what one challenge attempt is worth on average, and three numbers produce it. The first is your payout share: account size times your profit target gives the gross profit before a payout, and multiplying that by the split you keep gives the share. The second is your pass odds, the honest chance you clear the challenge. The third is the challenge fee. Multiply the share by your pass odds and subtract the fee. A positive figure means the attempt pays off on average, a negative one means the fee outweighs the expected payout, and trading carries risk of loss either way.

Fee refunds

How a Refunded Challenge Fee Changes Your Expected Return

Many firms refund the challenge fee on your first payout, which improves your real expected value, but not all do, and a failed attempt is rarely refunded. The calculator treats the fee as a cost you pay either way, so its expected value and break-even pass rate assume no refund. If your firm's refund policy returns the fee with the first payout, a passing attempt costs you less than the tool shows, while a failing attempt still costs the full fee. Confirm the refund terms in your firm's rules before you count on them, and remember trading carries risk of loss.

Break-even first

Break-Even Prop Firm Pass Rate to Check Before You Buy a Challenge

Before you buy a challenge, find the break-even pass rate: the challenge fee divided by the payout share you would keep, which is the pass percentage where expected value equals zero. In the page's default example, a $500 fee against a $6,400 share breaks even at 7.8%. Pass more often than your own break-even and the math favours you; pass less often and the attempt loses money on average. The calculator shows that threshold but does not estimate your pass rate, so hold it against an honest look at your trading record and your firm's refund terms. Trading carries risk of loss.
