R-multiple calculator

Measure a closed trade in units of what you risked, so trades of different sizes compare fairly.

  • Result in R—
  • Direction—
  • 1R per share—
  • Move per share—

Worked example

R-multiple = (exit − entry) ÷ (entry − stop). The same formula covers both directions: for a short, the stop sits above the entry, so the signs flip on their own.

Example: long at 100 with a stop at 95 risks 5 (1R). Exiting at 110 is +2R; exiting at 97.50 is −0.5R.

Common questions

Why measure trades in R?

Dollar results mix up how good a trade was with how big it was. In R, a small winning trade and a large one are compared on the same scale, which is what makes setups comparable.

What if I moved my stop?

Use the INITIAL stop. R is defined by the risk you took on when you entered; moving the stop later changes your exit, not your R.
