PROP FIRM ROI

Is this prop firm challenge worth it?

500 simulated trading paths show realistic profit outcomes, blowout probability, and whether the challenge fee makes financial sense for your trading stats.

A prop firm ROI calculator uses Monte Carlo simulation to determine whether a funded account challenge is worth the fee based on your win rate, profit split, and realistic blowout probability.

ROI = (Net Profit × Profit Split − Challenge Fee) ÷ Challenge Fee × 100

How to Use This Prop Firm ROI Calculator

1

Pick Your Prop Firm or Set Custom Rules

Select a preset (FTMO, Topstep, Apex, MyFundedFX) to auto-fill the account size, profit split, challenge fee, and drawdown limits. Or toggle to custom mode and enter any firm's rules manually.

2

Enter Your Trading Stats

Input your win rate, average winner, and average loser from your actual trading history. If you don't know these numbers, pull them from your journal or backtesting data. The calculator also accepts risk-per-trade percentage and number of trades per month.

3

Toggle Challenge Phase (Optional)

Enable the challenge toggle to simulate whether you'd pass the evaluation phase. The calculator factors in the profit target, time limit, and daily drawdown rules specific to each firm's challenge.

4

Read the Simulation Results

The calculator runs 1,000 Monte Carlo simulations of your trade sequence. You'll see your median profit, blowout probability, P10/P90 range, and an equity curve chart showing the distribution of possible outcomes. Below the chart, the optimal risk table shows which risk level maximizes your expected profit without excessive blowout risk.

5

Compare Different Scenarios

Adjust your risk per trade, switch between trailing and static drawdown, or try different firms. Watch how each change shifts your expected profit and blowout probability. This helps you find the setup where you keep the most money after fees and splits.

Key Metrics Reference

What each output means and how to use it when evaluating a prop firm challenge.

ROI

Expected ROI

Your projected return on the challenge fee investment. Calculated as (net profit after split minus challenge fee) divided by challenge fee. An ROI above 100% means you're expected to earn back more than double what you paid.

Blowout

Blowout Probability

The percentage of simulations where your account hits the maximum drawdown limit before reaching your profit target. A blowout rate above 40% means the challenge is statistically stacked against you at your current risk level.

Median

Median Profit

The middle outcome across all 1,000 simulations — half finish above this number, half below. Unlike average profit, median isn't skewed by a few extreme winners. This is the outcome you should realistically plan around.

P10/P90

Profit Range

The 10th and 90th percentile outcomes. P10 is your realistic downside (only 10% of simulations do worse), and P90 is your realistic upside. A wide spread means your results depend heavily on trade sequencing and luck.

EV

Expected Value per Trade

Your average dollar gain or loss on each trade, calculated as (win rate × avg win) minus (loss rate × avg loss). Positive EV is the minimum requirement for any prop firm attempt. Negative EV means you'll lose money regardless of risk management.

Optimal

Optimal Risk Level

The risk-per-trade percentage that maximizes expected profit while keeping blowout probability within acceptable bounds. The risk analysis table tests multiple risk levels so you can see exactly where the tradeoff between profit and survival tips.

Prop Firm vs. Trading Your Own Capital

The appeal of prop firm trading is access to large account sizes without risking your own money beyond the challenge fee. But the profit split, drawdown restrictions, and challenge costs change the math significantly. Here's a side-by-side comparison.

Factor Personal $25K Account $100K Prop Firm (80/20 Split)
Capital at risk $25,000 (your money) $500 challenge fee
Buying power $25,000 $100,000
Profit on a 10% return $2,500 (keep 100%) $8,000 (keep 80%)
Max drawdown allowed No external limit 5-10% (firm rules)
Daily drawdown limit None 2-5% (varies by firm)
Upfront cost $25,000 $155-$500 (challenge fee)
If you blow the account Lose real capital Lose the challenge fee only
Best for Traders with capital & no time pressure Consistent traders with limited capital

Key takeaway: Prop firms make financial sense when your expected profit after the split exceeds what you'd earn trading your own, smaller account — and when your strategy can survive the drawdown rules. This calculator runs the numbers so you don't have to guess.

Prop Firm ROI Formulas

The core formulas driving this calculator. Understanding them helps you spot which variable has the biggest impact on your profitability.

Expected Value per Trade

EV = (Win Rate × Avg Win) − (Loss Rate × Avg Loss)

A $50K account with 55% win rate, $300 avg win, and $200 avg loss produces an EV of $75 per trade. Over 80 trades per month, that's $6,000 in expected gross profit before the split.

Net Profit After Split

Net Profit = Gross Profit × Profit Split %

If the firm takes 20%, your $6,000 becomes $4,800. Some firms scale the split in your favor as you hit milestones — always check the fine print.

ROI on Challenge Fee

ROI = (Net Profit − Challenge Fee) ÷ Challenge Fee × 100

If you net $4,800 and paid a $500 challenge fee, your ROI is 860%. That's the number this calculator optimizes for — the return on the only money you actually put at risk.

Why Monte Carlo matters here: A single EV calculation tells you what should happen on average. But prop firms don't care about your average — they care about your worst drawdown during a specific sequence of trades. Monte Carlo simulation tests 1,000 different orderings of your wins and losses to show what actually happens in practice.

Worked Example: Is an FTMO $100K Challenge Worth It?

Let's walk through a real scenario. Suppose you have these stats from 6 months of journaling in TradeZella:

Metric Your Value
Win rate52%
Average winner$420
Average loser$280
Trades per month60
Risk per trade1.5% of account

Step 1 — EV per trade: (0.52 × $420) − (0.48 × $280) = $218.40 − $134.40 = $84.00

Step 2 — Monthly gross: $84 × 60 trades = $5,040

Step 3 — After FTMO's 80/20 split: $5,040 × 0.80 = $4,032

Step 4 — Net after $540 challenge fee: $4,032 − $540 = $3,492

Step 5 — ROI: $3,492 ÷ $540 × 100 = 647%

That's the expected case. But what about blowout risk? With 1.5% risk per trade and a 10% max drawdown, the Monte Carlo simulation shows roughly a 12% chance of blowing the account before reaching meaningful profit. Dropping risk to 1% cuts the blowout rate to under 5% while still producing strong returns.

The lesson: EV tells you the destination. Monte Carlo shows you the potholes on the road. A strategy that looks profitable on paper can still blow up 1 in 5 times if the risk per trade is too high relative to the drawdown limit.

Frequently Asked Questions

How do I calculate prop firm ROI?

ROI = (Net Profit − Challenge Fee) ÷ Challenge Fee. Our calculator runs 500 simulations using your win rate and average win/loss to show the range of likely outcomes, not just best-case scenarios.

What is a good win rate for prop firm trading?

Most successful prop traders have win rates between 45-60%. What matters more is your profit factor (average win ÷ average loss). A 45% win rate with 2:1 reward-to-risk is more profitable than 60% with 1:1.

How does the profit split work?

Prop firms typically offer 70-90% profit splits. You keep that percentage of profits; the firm keeps the rest. Higher splits mean more money in your pocket but often come with stricter rules.

What happens if I blow the account?

You lose access to the funded account and forfeit any unrealized profits. Some firms offer resets for a fee. Our calculator shows your blowout probability based on your trading stats.

How many days to break even on the challenge fee?

Break-even depends on your expected value per trade and trades per day. Our calculator shows the median days to recover your challenge fee investment.

Should I trade the same strategy on a prop account?

Your strategy should account for the firm's drawdown rules. Strategies that work with 10%+ drawdowns may fail under 5% daily limits. Adjust position sizing accordingly.

Are prop firms worth it for beginners?

Generally, no. If you're not consistently profitable on a small personal account, prop firm rules will accelerate losses. Prove your edge first, then scale with prop capital.
