R-Multiple Calculator
Measure Every Trade in R
Enter your entry, stop loss, and exit price to instantly calculate your R-multiple. See how each trade measures against your initial risk.
A trade that risked $1.50 per share and gained $3.75 is a +2.5R winner — regardless of position size.
Optional — for dollar amounts
Enter your entry, stop loss, and exit price to see results.
Understanding R-Multiples
The universal language for measuring trade performance
What is R?
R represents your initial risk on a trade — the distance from entry to stop loss. All profits and losses are measured as multiples of this risk unit, making results comparable across different stocks and position sizes.
1R = Entry Price - Stop Loss (for longs)
R-Multiple Calculation
Your R-multiple is how much you actually made or lost, divided by your initial risk. A +2R trade means you made twice what you risked. A -1R trade means you lost exactly your planned risk.
R-Multiple = P&L Per Share / Initial Risk Per Share
Why R-Multiples Matter
R-multiples standardize performance. A $500 profit on a $250 risk is the same +2R as a $2,000 profit on a $1,000 risk. This lets you compare trades fairly regardless of position size.
$500 / $250 risk = +2R = $2,000 / $1,000 risk
Trading without a defined stop loss
Without a stop, you can't calculate R. Every trade needs a predetermined exit point before entry.
Moving your stop loss further away
This increases your 1R after entry, inflating potential losses. If you move your stop, recalculate your R using the original stop.
Judging trades by dollar P&L only
A $1,000 profit with $2,000 at risk (+0.5R) is worse than a $300 profit with $100 at risk (+3R). Always measure in R.
Cutting winners at 1R
If your average loss is -1R, you need winners above +1R to be profitable. Let winners run beyond your initial risk.
Ignoring R on losing trades
A -0.5R loss (exited early) is far better than a -2R loss (gap through stop). Track losing R-multiples to improve risk management.
