What is break-even in prop firm trading?

Break-even is the moment your cumulative payouts from a funded prop firm account equal the total money you've spent to get funded — challenge fees, resets, activation, monthly platform and data fees. Before break-even, the account is a net loss. After break-even, every additional payout is pure profit. Most traders massively underestimate how long this takes when blowup risk is factored in.

Why does break-even depend on blowup probability?

A blowup resets your payout clock and, if you choose to reset the account, adds a reset fee to your cumulative cost. A 20% monthly blowup probability means roughly 1 in 5 months, the account terminates. Each termination pushes break-even further into the future, both by missing a payout that month and by adding reset costs. Two traders with identical monthly payouts can have dramatically different break-even timelines based purely on their blowup rates.

What do P10, P50, and P90 break-even mean?

These are percentile outcomes from a Monte Carlo simulation. P10 is the optimistic 10th percentile — 10% of simulated paths break even this fast or faster. P50 is the median — half the paths break even by this month. P90 is the pessimistic 90th percentile — only 10% of paths take this long or longer. The spread between P10 and P90 tells you how much variance the blowup probability introduces into your expected timeline.

Should I reset or quit after a blowup?

The calculator supports both modes. Reset mode assumes you pay the reset fee and continue earning — break-even keeps moving but the added cost delays it. Quit mode assumes you stop entirely after the first blowup, so paths that blow up before break-even never recover. Quit mode shows much higher 'never break even' percentages. The right choice depends on whether you believe your strategy edge is real (favours reset) or whether a blowup reveals a flaw (favours quit).

Does the challenge fee refund improve break-even?

Yes — firms like FTMO, FundedNext, and E8 Markets refund the challenge fee on the first successful payout. This calculator deducts the refund from cumulative cost on the first non-blowup month, which materially accelerates break-even for low-true-cost firms. However, the refund is worthless if you blow up before your first payout, which is why quit-mode with a refund firm can still look grim.

Cumulative Payout vs. Cumulative Cost1,000 Monte Carlo paths
How It WorksSimulation Logicbreak_even_month = first month where cumulative_payout ≥ cumulative_cost
Each month, roll against p_blowup:
  if blowup & reset  → cost += reset_fee, no payout this month
  if blowup & quit   → path locked, no further earnings
  otherwise           → payout += monthly_payout (and apply refund on first such month)

Naïve break-even is almost always wrong. The obvious calculation — true cost divided by monthly payout — assumes you never blow up, never reset, and earn consistently every month. At your current inputs that gives 0.2 months. The Monte Carlo version accounts for the reality that at your 20% monthly blowup rate, roughly 1 in 5 months ends in a blowup, and each blowup either pauses earnings for a month (reset) or ends them entirely (quit). The spread between your naïve number and the P50 is the cost of ignoring variance.
The P10-to-P90 spread measures how lucky vs. unlucky matters. A tight spread means outcomes are predictable — break-even will land near P50 regardless of month-to-month variance. A wide spread means the blowup lottery dominates. If your P90 is double your P10, the honest answer is "I don't really know when I'll break even" — and that uncertainty should feed back into whether this firm and account size is the right bet in the first place.
Reset vs. quit is a strategy question, not a math question. Reset mode is the right model if you believe your edge is real and blowups come from bad luck or inevitable drawdowns. Quit mode is right if a blowup usually reveals a flaw in your setup — bad risk management, an untested strategy, emotional trading. The research suggests most funded traders would be better off in quit mode than they think, because resets compound costs faster than edges compound profits.
The "never break even" percentage is the sharpest signal on this page. If 30% of paths never recoup their cost within the time horizon, that's the probability you're donating money to the firm regardless of how passing feels. This number climbs fast with higher blowup rates and higher true costs, and it's the number that makes or breaks the economics of any "cheap challenge, high reset fee" plan.
What this tool does NOT model: time-varying payout amounts (the simulation treats monthly payout as constant), payout caps and cycle limits, consistency-rule failures that block specific payouts, payout frequency (treated as monthly), or the probability you voluntarily stop trading before the horizon for unrelated reasons. Treat the headline number as a directional estimate — the shape of the fan chart and the never-break-even percentage carry more information than any single month figure.

The middle scenario. Half of all simulated paths earn more than this by month M, half earn less. The line you track.
░░P10 / P90 Band
The shaded area covers 80% of likely outcomes. Wide band = high variance from blowup luck. Narrow = predictable.
━━Cumulative Cost
Starts at your true cost and climbs with each reset. Where this line crosses the payout line is your break-even month.
┈┈Cost P90 (pessimistic)
Cost under the unluckiest 10% of scenarios — multiple resets compounding. Only appears when reset mode is on and blowups are frequent.

Where the median payout line crosses cost — your expected break-even point.
Next StepsBreak-even answers "when do I stop losing money?" — but it depends on three inputs that this calculator treats as given. The True Cost Calculator gives you a sharper number for the cost side. The EV Calculator evaluates whether you should even attempt the challenge in the first place. And the Trailing Drawdown Visualizer informs the blowup probability input — different drawdown mechanics make blowups more or less likely for the same strategy.
