Wilks Calculator
Enter your body weight and total lifted to find your Wilks score.
This calculator uses the original Wilks formula coefficients for men.
How the Wilks score is calculated
The Wilks score multiplies your total weight lifted by a coefficient derived from a polynomial formula based on your body weight. This coefficient is designed so that lifters of different body weights can be compared on a level playing field, since raw strength naturally increases with body mass.
The formula uses five polynomial coefficients applied to your body weight (in kg) to compute a scaling factor, then multiplies your total lifted weight by that factor — heavier lifters get a smaller coefficient, while lighter lifters get a larger one, for a given total.
Frequently asked questions
Why do powerlifters need a scoring formula like this?
Raw totals naturally favor heavier lifters since more body mass generally allows for more absolute strength. The Wilks score adjusts for this, letting lifters of very different body weights be ranked fairly in open competitions.
Is the Wilks formula still used in competitive powerlifting?
The Wilks formula was widely used for years, but many federations have since adopted newer formulas (like the IPF GL Points or DOTS formula) that some consider more accurate across the full range of body weights. Check which formula your specific federation or competition uses.
Does this calculator work for women's lifts too?
No — this calculator uses the men's Wilks coefficients. Women's Wilks formula uses a different set of polynomial coefficients, since the relationship between body weight and strength differs somewhat by sex.
