Enter your gender, bodyweight, and total weight lifted to calculate your Wilks Score — the powerlifting metric that compares strength across different body weights. Choose between kg and lb units, and see how your lifts stack up against athletes of any size.

The Wilks Score (also called the Wilks Coefficient) is a formula used in powerlifting to compare the relative strength of lifters across different body weights. It was developed by Robert Wilks of Powerlifting Australia and allows a fair comparison between lighter and heavier athletes.
The Wilks Score is calculated by multiplying the total weight lifted (in kg) by a coefficient derived from the lifter's bodyweight using a polynomial equation. The coefficients differ for male and female lifters. A higher score means greater relative strength.
Generally, a Wilks Score above 300 is considered good for recreational lifters, above 400 is competitive, above 500 is elite, and above 600 is world-class. Scores vary by gender and the specific lift or total being measured.
The Wilks formula can be applied to any single lift (squat, bench press, or deadlift) or to the powerlifting total (squat + bench + deadlift combined). Simply enter the relevant weight lifted in the 'Total Weight Lifted' field.
Yes. Select 'Pounds (lb)' from the Units option and the calculator will automatically convert your bodyweight and lifted weight to kilograms before applying the Wilks formula, giving you an accurate score.
The Wilks Score was the standard for many years, but some federations have moved to newer formulas like IPF GL Points or DOTS. However, Wilks remains widely used and recognised for comparing lifters across bodyweight categories.
Yes, the Wilks formula uses a separate set of polynomial coefficients for male and female lifters. This accounts for biological differences in strength-to-bodyweight ratios, making cross-gender comparisons more equitable.
The Wilks formula is designed for bodyweights ranging approximately from 40 kg to 200 kg (about 88 to 440 lb). Results outside this range may be less reliable, as the polynomial coefficients are calibrated for competitive powerlifting bodyweight classes.
