R-Multiple Calculator
Enter the risk you planned and the P&L you actually got, and see the trade's R-multiple — the same calculation Fillbook runs on every logged trade automatically.

+1.50R
A 750 result on 500 of planned risk works out to +1.50R — +1.50R means the trade returned that many multiples of what you were willing to lose.
The formula
R-multiple = P&L ÷ planned risk
R-multiple normalizes trades of different sizes onto the same scale, so a $50 scalp and a $500 swing trade can be compared fairly — both as "how many multiples of planned risk did this return." This is the exact formula Fillbook's own metrics use for every trade with a planned risk logged.
Worked example
You plan to risk $200 on a trade (your entry to your stop). The trade works and you close it for a $500 gain. R-multiple = 500 ÷ 200 = 2.5R — the trade returned two and a half times what you were willing to lose. A trade that hits its stop exactly returns -1R by definition.
Common mistakes
Using the dollar amount you actually lost on a partial stop-out (rather than the risk you originally planned) understates R on losers. Forgetting to log a planned risk at all means the trade can't be R-scored — Fillbook treats those trades as having no R-multiple rather than guessing one.
Track R-multiple automatically on every trade
Log a planned risk once per trade and Fillbook calculates R-multiple, average R, and expectancy for you — no spreadsheet formula to maintain.

There's no universal "good" number — it depends on your win rate. A strategy that wins 40% of the time needs an average winner bigger than 1.5R just to be profitable after losers. What matters is your average R-multiple across many trades (your expectancy), not any single trade's result.
Dollar P&L mixes up how much you risked with how the trade performed — a $500 winner on $1,000 of risk and a $500 winner on $100 of risk are very different trades. R-multiple strips out position size so you can compare execution quality across trades of any size.
Yes — every trade you log with a planned risk gets an R-multiple calculated automatically, plus your average R-multiple across your full history, broken down by setup and symbol.
