How the r-multiple calculator works

R is the professional's unit of trading. One R is the amount you risked on a trade — the distance from entry to stop. Measuring outcomes in R (a +2R win, a −1R loss) makes trades of different sizes and prices directly comparable, and turns your track record into a clean, honest distribution.

  • Your initial risk (1R) is the distance from your entry to your stop-loss.
  • Your result is the distance from your entry to your actual exit.
  • The R-multiple is result ÷ initial risk: exiting at +2R means you made twice what you risked; −1R means you took your full planned loss.
R-multiple = (Exit − Entry) ÷ |Entry − Stop| (reverse the sign for shorts)

R-Multiple Calculator — FAQ

What is an R-multiple?

An R-multiple expresses a trade's profit or loss as a multiple of the money you initially risked (your "1R"). A trade that makes three times your risk is a +3R; one that hits your stop is −1R. It normalises every trade to the same scale regardless of size.

Why measure trades in R instead of dollars?

Dollars are distorted by position size and price — a $500 win could be a great trade or a reckless one. R strips that away and shows the quality of the decision. Your expectancy (average R per trade) is the truest measure of an edge.

What is a good average R?

Any positive average R (your "expectancy") means a profitable system over enough trades. Many solid systems sit around +0.2R to +0.5R per trade. The goal isn't huge single wins — it's a positive average across a large, consistent sample.
