Wilks Score Calculator

Summary

The Wilks score (Wilks coefficient) is a formula developed by Robert Wilks to compare powerlifting totals across different body weights and between male and female lifters. It adjusts raw totals using a polynomial function of body weight, producing a single normalized score. Higher scores indicate better relative strength regardless of body weight class.

How it works

1. Enter your body weight in kilograms or pounds.
2. Select your sex (male or female) — separate Wilks coefficients apply to each.
3. Enter your total (combined squat + bench press + deadlift).
4. The calculator applies the Wilks polynomial formula to your body weight to produce a coefficient.
5. Your total is multiplied by the coefficient to produce your Wilks score.
6. Use the score to compare yourself against other lifters regardless of body weight.

Use cases

• Compare powerlifting performance across different body weight classes.
• Rank lifters of different sexes on a fair, normalized basis.
• Track your own strength progress independent of body weight changes.
• Determine best lifter awards at powerlifting meets.
• Set personal strength goals relative to elite benchmarks.
• Compare yourself to world-record holders on a normalized scale.
• Plan competition strategy across weight classes.
• Evaluate programming effectiveness independent of weight fluctuations.
