Wilks Calculator
Calculate your Wilks score, the classic way to compare powerlifting totals across bodyweights. Enter your sex, bodyweight and total lifted, and the original Wilks formula returns your coefficient and score so a lightweight and a heavyweight can be ranked on a level field.
How to use the Wilks calculator
- Select your sex, since the Wilks formula uses a different curve for each.
- Enter your bodyweight in kilograms (or switch on the pound helper).
- Enter your total lifted to see your Wilks coefficient and Wilks score.
Examples
90 kg male, 600 kg total
Male, bodyweight 90 kg, total 600 kg
Coefficient about 0.638, Wilks score about 383
60 kg female, 400 kg total
Female, bodyweight 60 kg, total 400 kg
Coefficient about 1.115, Wilks score about 446
Frequently asked questions
What is the Wilks score?
The Wilks score is a way to compare powerlifting totals between lifters of different bodyweights. It multiplies your total by a coefficient derived from your bodyweight and sex, so a 60 kg lifter and a 120 kg lifter can be ranked on equal terms. A higher score means a stronger lift relative to size.
What is the Wilks coefficient?
The coefficient is the multiplier the formula assigns to your bodyweight. It comes from a fifth-order polynomial fitted by Robert Wilks. In the normal competition range it falls as bodyweight rises, which is why heavier lifters need a bigger total to reach the same Wilks score.
Which Wilks formula does this use?
This tool uses the original Wilks formula with the standard male and female coefficient sets. Inputs are in kilograms, the unit the formula was built for. Note that many federations have moved to Wilks 2 or the IPF GL points, so check which system your meet uses.
Why does a heavier lifter get a lower Wilks for the same total?
The formula assumes that, pound for pound, heavier lifters can move more absolute weight. To keep the comparison fair it shrinks the coefficient as bodyweight climbs, so two lifters with the same total but different bodyweights get different scores, with the lighter lifter scoring higher.
What is a good Wilks score?
It depends on experience and sex, but as a rough guide a Wilks around 300 is a solid intermediate level, 400 is advanced, and 500 and up is elite or competitive at a national level. Use it to track your own progress over time as much as to compare with others.
