Wilks Calculator
Calculate your Wilks 2020 strength coefficient score to compare raw lifting performance across different weight classes.
About the Wilks Coefficient
The Wilks formula normalizes strength performance in competitive powerlifting, allowing athletes of different body weights and sexes to be ranked fairly against one another.
Why Wilks is Necessary
Lifting strength scales with cross-sectional muscle area rather than body mass directly. Larger lifters lift heavier gross weights, but lighter lifters frequently display superior strength-to-weight leverage ratios.

Frequently Asked Questions
What is the Wilks 2020 update?
The updated 2020 polynomial coefficients adjusted for historical statistical bias at the extreme light and heavy ends of the bodyweight curve.
Does Wilks differentiate between raw and equipped lifting?
No. Wilks measures gross total relative to bodyweight regardless of whether supportive bench shirts or squat suits are worn.
How does Wilks differ from the IPF GL or DOTS formula?
The IPF GL and DOTS scoring formulas use alternative statistical regression curves, but all share the common purpose of normalizing relative lifting strength.
Can I use pounds instead of kilograms?
The polynomial constants require bodyweight and lifted totals to be calculated in metric kilograms.
