RPE Calculator

Rate of perceived exertion based training calculator.

How It Works

  1. Log your last set. Enter weight, reps, and RPE (6–10 scale) from your most recent working set.
  2. Estimate 1RM. The calculator derives your estimated one-rep max using the RTS RPE chart.
  3. Read the RPE chart. See % of 1RM for each RPE level at your target rep count.
  4. Plan backoff sets. Drop weight by a percentage for volume work after top sets.
  5. Set target weights. Find the load for any rep count and RPE combination.

Pair with our One Rep Max Calculator or VDOT Calculator.
