RPE Calculator

RPE Calculator

RPE-based training adjusts the weight to how hard a set actually feels instead of a fixed percentage. Enter the weight you lifted, the reps and the RPE of that set, and this calculator uses the standard RPE chart to estimate your 1RM and suggest working loads for common rep targets. RPE 10 means no reps left in the tank; RPE 8 means roughly two in reserve. It is the basis of modern autoregulated programs and pairs well with a 1RM percentage plan.

Based on the standard RPE/RIR chart. RPE (rate of perceived exertion) rates how hard a set was: RPE 10 is a true max, RPE 8 means you could have done about 2 more reps. It is a more flexible alternative to fixed percentages for autoregulated training.
