The three questions every prop trader needs answered
Whether you're paying for your first challenge or your tenth, three numbers decide whether prop trading is going to work for you. Almost nobody calculates them before paying. PropFirmBacktester is built to answer all three.
1. Can you actually pass this challenge?
Not the industry average — your number, against the exact rules of the firm you're considering, given the way you actually trade. The tool runs your strategy through thousands of simulated attempts at the full ruleset and tells you the share that survived. If barely any of them make it, paying hundreds for the eval is a decision worth thinking twice about. If most of them do, the math is on your side. Either way you know, before you pay, instead of after.
2. Once funded, will you ever get paid?
Passing isn't paying. Funded accounts have their own drawdown rules, their own daily loss limits, and payout gates — minimum profit buffers, qualifying profit days — that decide whether you actually withdraw cash or just trade until the account dies. The tool simulates this stage separately and tells you the probability you reach a real payout once funded. For most traders, this is where the money quietly disappears. The eval fee already cost something. Trading a funded account that was never going to pay costs a lot more — time, focus, and the next eval fee after this one.
3. Across many challenges, do you compound or bleed?
One pass is luck. One payout is luck. The number that actually matters is what happens when you run this for real, over months and years, paying eval fees on the failures and banking payouts on the wins. The tool simulates your full journey across 5 to 200 sequential challenges, subtracts every fee, banks every payout, and shows you the expected equity curve. Over time, are you net profitable — or are you funding the firm?
Who this is for
It's for you if —
- You've paid for evaluations before and don't fully know why some passed and some failed.
- You're choosing between two firms or two account sizes and the rulesets look almost identical on paper.
- You're already funded and want to know if your payout rules are as friendly as they look.
- You think you have an edge and want to know if the firm's rules let you keep it.
- You'd rather know one honest number than read ten flattering ones.
It's not for you if —
- You're looking for trading signals or a strategy. The tool measures yours; it doesn't supply one.
- You believe one challenge is enough to know whether you're profitable. (One challenge is luck — that's the whole premise.)
Why traders trust the numbers
Hedge funds don't bet on instinct. Before a strategy ever sees real capital, it's run through thousands of simulated paths, stress-tested against every rule that could end it, and priced honestly — does this make money over time, or doesn't it. That's the same math, the same discipline, applied to the one question you've been making blind since the day you paid for your first challenge: does the firm's ruleset let your trading survive, or doesn't it.
For years, retail traders have been the only ones in this game without the math. PropFirmBacktester closes that gap. The number you get back isn't a guess, an average, or a salesperson's promise — it's the share of thousands of simulated versions of you that made it through. Some passed. Some didn't. Some got paid. Some bled out over fifty challenges and didn't even notice.
You're going to find out which one you are. The question is whether you find out before you pay, or after.
How we stay honest in a category that mostly isn't
Three structural choices keep this clean. No affiliate fees from any prop firm — not a cent. No signals, no Discord, no course. The whole business model is $49 a month for the software. When the math comes back negative on a strategy, the tool says so plainly — we'd rather lose a sale than build a reputation on flattery.
Methodology
PropFirmBacktester is decision-grade math for pricing a prop firm decision before you pay for it. The model treats trade outcomes as draws calibrated to your stated win rate and average win/loss — the standard institutional approach for evaluating ruleset-driven path-dependent gates. It's built to answer "given my trading and these specific rules, what should I expect?" — not to predict any individual future challenge. Educational tool, not financial advice.
Questions, answered.
Is PropFirmBacktester legit?+
Yes. It's paid software ($49/month) — a Monte Carlo simulator that models any prop firm's exact ruleset against your trading stats. No affiliate fees from any firm, no signals, no Discord. The business model is the subscription, full stop.
What does PropFirmBacktester actually tell me?+
Three things every prop trader needs to know before paying for a challenge. Your real probability of passing a specific firm's challenge with your own strategy. Your probability of actually reaching a withdrawal once funded — accounting for the funded-account rules and payout gates. And your expected long-run profit or loss across 5 to 200 sequential challenges, with every eval fee and every payout factored in. The first two answer your odds. The third answers whether the odds are enough to keep playing.
How is this different from a free prop firm calculator?+
Free calculators give you a single static pass rate from a formula. PropFirmBacktester runs thousands of trade-by-trade simulations against the firm's exact rules, then separately simulates the funded-account stage, then composes both into the joint probability of actually getting paid — and projects your long-run equity curve across many challenges. It's the difference between a number on a page and the answer to whether you should be doing this at all.
Does it work for one-phase and two-phase challenges?+
Both, with independent rule sets and targets per phase. The engine also handles the funded-account stage — profit buffer, qualifying profit days, ongoing drawdown and daily-loss limits — which is the part most calculators skip entirely.
How do you make money?+
$49 a month for the software, full stop. No affiliate fees from any prop firm. No signals, no Discord, no course. We'd rather charge for the tool than profit from sending traders to firms where they're more likely to fail.
$49 to find out if the next challenge is even worth buying.
A losing strategy run 100 times costs thousands in fees. $49 buys you the answer before you spend another cent.

Note on methodology: the model assumes each trade is independent of the next. Real trading has streaks — tilt, fatigue, regime changes — that this model doesn't capture. Treat the numbers as an honest baseline, not a guarantee. PropFirmBacktester is independent and not affiliated with any prop firm.
