Account Size Finder Calculator — Frequently Asked Questions

Q.What prop firm account size should I start with?

Start with the account size where 1% risk per trade equals an amount you are comfortable losing. For a $25K account, 1% = $250 per trade. For a $100K account, 1% = $1,000 per trade. If losing $1,000 on a trade would cause you to break your rules or revenge trade, start with $25K or $50K.

Q.Is a larger prop firm account always better?

No — larger accounts have the same drawdown percentages but much larger dollar amounts at stake. Psychological pressure increases with account size. Start at a size where you trade your system without emotion, then scale up after consistent results. Many traders perform better on $50K than $200K due to reduced pressure.

Q.How much can I earn on a $100K FTMO account?

With FTMO at 80% payout: If you earn 5% monthly ($5,000), you receive $4,000 (80%). At 10% monthly ($10,000), you receive $8,000. Realistic: experienced funded traders average 3–7% monthly on their accounts. At 5% on $100K = $4,000/month take-home. Scale up accounts as consistency is proven.

Q.Should I run multiple prop firm accounts?

Yes — diversifying across 2–3 prop firms at smaller sizes is often better than one giant account. If you blow one, you still have income from others. Firms like FTMO allow multiple accounts. Many funded traders run $50K accounts at 3 different firms simultaneously for $150K total buying power with diversified drawdown risk.

Q.What monthly return is realistic for a funded trader?

Realistic monthly returns for consistently funded traders: 3–5% (conservative, high pass rate), 5–10% (aggressive, higher drawdown risk), 10%+ (very aggressive, frequent account failures). Most experienced funded traders target 4–6% monthly — enough for good income without excessive risk. An honest assessment of your backtested returns is the best starting point.
