How prop firms make money: evaluation fees, profit splits and simulated versus live accounts
Follow the money through a prop firm's business model, separate fee income from trading income, and see why most retail prop accounts are simulated.
What you will learn
- What a retail prop firm actually sells and where its revenue comes from.
- The difference between a simulated (demo) funded account and a live account, and why it matters to you.
- How to build a simple income statement for a hypothetical prop firm and read the incentives in it.
- Three questions to ask about any firm's model before you pay an evaluation fee.
Explanation
A proprietary trading firm (prop firm) traditionally trades its own capital with employed or contracted traders. The retail prop firm that advertises online is a different product. It sells an evaluation (also called a challenge): you pay a one-time fee, trade an account under a set of rules, and if you meet the target you receive a funded account. From then on, profits made under the rules are shared through a profit split, for example 80 percent to you and 20 percent to the firm.
Simulated versus live accounts
Most retail prop accounts are simulated: the funded account is a demo account with a price feed, and no real order reaches a market. The firm pays your share of simulated profits out of its own money. Some firms copy selected traders into a live account at a broker (the A-book approach) or hedge only part of the flow. A firm that runs simulated accounts is, economically, the counterparty to your results: every euro it pays you is a cost, exactly like a bookmaker paying a winning bet. Terms and conditions usually say so, often with words such as "simulated", "virtual" or "demo", and you should read them. The underlying products are CFDs and futures, which can lose money quickly whether the account is real or simulated.
Where the revenue comes from
- Evaluation fees are earned immediately. Whether you fail, pass or never log in again, the fee is revenue. Resets, retries and add-ons (higher leverage, no time limit, weekend holding) are extra fees.
- Profit splits are only meaningful if the firm actually has live exposure. In a purely simulated model the firm keeps nothing from "its share"; the split simply reduces its cost per payout.
- Affiliate and discount-code marketing: influencers and comparison sites earn a commission per sale, which tells you why the product is promoted so heavily.
- Breach and inactivity: a funded account that breaches a rule ends all future payout obligations.
The incentive map
This structure produces predictable incentives. Rules that are easy to misread (daily loss on equity instead of balance, consistency rules, news windows) raise the failure rate without changing the headline target. A high headline split (90 percent) costs the firm little if few traders reach a payout. None of this means a firm is dishonest; it means you should treat the fee as the price of a product and calculate what you receive for it, which is what lessons 4 and 7 do in detail.
Worked example
Hypothetical example: a firm sells 1,000 evaluations in one quarter for a nominal €100,000 account at €500 each. Assumptions (all invented for teaching): 10 percent of buyers pass, 30 of the 100 funded traders reach at least one payout, their average simulated profit at payout is €5,000, the split is 80 percent, the fee is refunded with the first payout, affiliates receive 20 percent of fee revenue, and other operating costs are €120,000. Taxes are excluded.
| Item | Calculation | Amount |
|---|---|---|
| Fee revenue | 1,000 × €500 | €500,000 |
| Payouts to traders | 30 × €5,000 × 0.80 | −€120,000 |
| Fee refunds | 30 × €500 | −€15,000 |
| Affiliate commissions | 20% × €500,000 | −€100,000 |
| Other operating costs | given | −€120,000 |
| Operating result | €145,000 |
Two observations. First, payouts and refunds together are €135,000, or €135 per buyer against a €500 fee, so the average buyer receives back 27 percent of what was paid. Second, the firm's result depends far more on sales volume and failure rate than on anyone's trading skill. If the pass rate doubled to 20 percent with everything else equal, payouts and refunds would double to €270,000 and the result would fall to €10,000. The firm's rule design and the trader's edge pull in opposite directions.
Common mistake
Practice activity
On paper, rebuild the income statement above with one change: the firm introduces a free retry that lifts the pass rate to 15 percent, and the number of funded traders who reach a payout rises in proportion (45 instead of 30). Everything else is unchanged. Calculate the new operating result and the amount returned per buyer.
Show solution
Payouts: 45 × €5,000 × 0.80 = €180,000. Refunds: 45 × €500 = €22,500. Result: €500,000 − €180,000 − €22,500 − €100,000 − €120,000 = €77,500. Returned per buyer: (€180,000 + €22,500) / 1,000 = €202.50, or 40.5 percent of the fee. The firm is still profitable, which shows why "easier" rules can be offered as marketing; the profit simply shrinks. Limitations: real firms have very different cost structures, and pass rates vary widely by rule set and market conditions.
Key takeaways
- A retail prop firm sells evaluations; fees are revenue on day one, payouts are its main variable cost.
- Most funded accounts are simulated, so the firm is economically your counterparty.
- Rule design, pass rates and marketing commissions determine the firm's profit far more than trading results.
- Treat the fee as a product price and calculate what you get for it before buying.

The next lesson decodes the rule set itself: profit targets, daily loss limits, consistency rules, minimum trading days and news restrictions.
