R Multiple Calculator
The fairest way to measure any trade outcome. R multiples remove position size from the equation and show you exactly how well you executed.
R multiples let you compare trades fairly regardless of position size. A +2R trade is twice as good as a +1R, whatever the dollar amount.
What is an R multiple?
R is the amount you risked on a trade (from entry to stop loss). An R multiple expresses your trade outcome as a multiple of that risk. A +2R trade means you made twice what you risked. A –1R trade means you lost your full risk amount. A –0.5R trade means you closed at half your stop loss distance.
Why R multiples are more useful than dollars or percentages
A $200 profit on a $10,000 account is very different from a $200 profit where you risked $2,000 to make it. R multiples normalise for position size and account balance, making it possible to compare trades fairly and analyse your edge across hundreds of trades.
Building an R-based trading journal
Log every trade as an R multiple (+1.8R, –1R, +0.5R). Over time, calculate your average R per trade. Multiply by your trade frequency and you have your expected monthly growth. This is the quantitative foundation of professional trading.
