## Quick Answer

Estimate your one-rep max using submaximal lifting data. Input weight, reps, and RPE rating to calculate your 1RM and generate custom training percentage weights.

## Definition

In strength training and powerlifting, an RPE calculator is a tool used to estimate a lifter's one-rep maximum (1RM) based on a submaximal set. The Rate of Perceived Exertion (RPE) scale, typically ranging from six to ten based on Reps in Reserve, measures the subjective intensity of a completed set. By matching reps and RPE to standard intensity percentages from the Reactive Training Systems chart, the calculator divides the weight lifted by the estimated intensity to project a theoretical maximum single lift. Strength coaches and powerlifters utilize this calculator for autoregulated training, enabling them to adjust daily working weights according to current physical readiness.

## How to Use

1. **Enter weight and reps** — Type the weight lifted and the number of reps completed in your set.
2. **Set RPE rating** — Select your perceived RPE value from six to ten, based on how many additional reps you could have done.
3. **Read estimated maxes** — Review your estimated one-rep max and the corresponding percentage breakdown table.
