Prop Firm Daily Loss Calculator

Most blown challenges don't die on the max drawdown — they die on the daily loss limit, usually on a revenge trade sized against the original allowance instead of what's actually left. This calculator answers the only question that matters mid-day: how much room do I still have, and what size still fits?

Remaining daily room $5,000
Daily allowance: $5,000 Used today: $0 (0%) Max XAUUSD lots at that stop: 10.00

Worst case at the stop keeps you exactly at the limit — leave a buffer for spread and slippage.

Firms measure the day from a balance or equity snapshot (FTMO: midnight CET) and most count floating losses. This tool is a planning aid — the number in your firm's dashboard is the one that counts.

Daily loss allowance by account size

Account5% rule4% rule3% rule
$5,000$250$200$150
$10,000$500$400$300
$25,000$1,250$1,000$750
$50,000$2,500$2,000$1,500
$100,000$5,000$4,000$3,000
$200,000$10,000$8,000$6,000

These are full-day allowances from a flat start. After any loss, your real number is the remaining room above — recalculate before every trade, not once per day.

Worked example: surviving a red morning

$100,000 account, 5% rule → $5,000 allowance. You're down $2,000 closed and $500 floating: used = $2,500, remaining = $2,500. Planning a gold trade with a $5.00 stop? Max size = 2,500 ÷ (5 × 100) = 5.00 lots — but sizing to the full remaining room means one normal loss ends your day at the hard limit. A calmer play is to risk a fraction of the room (e.g. 25% → 1.25 lots) and keep the gold lot size calculator math at 0.25–0.5% of the account. The full framework is in the prop firm risk guide and the prop firm risk planner.

FAQ

Daily loss rule questions

What is a max daily loss rule?

A cap on how much your account may lose within one trading day before the challenge or funded account is breached. Common limits are 5% (many 2-step challenges), and 3–4% (many 1-step programs). The base and reset time differ by firm — for example FTMO measures from the start-of-day balance/equity snapshot at midnight CET. Always confirm the exact rule in your firm's dashboard.

Does floating (open) P/L count toward the daily loss?

At most firms, yes — the limit is monitored on equity, so an open position that is deep underwater can breach the rule even if you never close it. That is why this calculator asks for open P/L as well as closed P/L.

How much is 5% daily loss on a $100,000 account?

$5,000. If you are already down $2,000 closed and $500 floating, your remaining room is $2,500 — and your next position size should be calculated against that number, not against the original $5,000.

How do traders avoid breaching the daily limit?

Three habits cover most of it: risk a small fixed fraction per trade (0.25–1%), pre-calculate position size so a stop-out costs exactly that fraction, and stop trading for the day after a fixed personal limit (for example −2%) long before the firm's hard limit.
