About this calculator

The Wilks formula normalizes powerlifting totals across bodyweights, letting a 60kg lifter and a 120kg lifter compete on a single score. Higher = stronger pound-for-pound. 500+ is elite international level (the Wilks 500 club). Most powerlifting federations have moved to IPF GL or Wilks2 since 2020 due to bias issues with the original Wilks at extreme bodyweights โ€” but the original Wilks remains the most widely understood gym-floor benchmark.

Frequently asked

Original Wilks (1995): widespread, slightly biased at extremes. Wilks2 (2020): updated coefficients. IPF GL: federation's current standard. All similar within ยฑ5 points.
