Wilks Calculator
A bodyweight-normalized score (Wilks 2020 coefficients) that lets lifters at different bodyweights be compared on one scale.
Squat + bench + deadlift combined, or a single lift if that's what you're scoring.

How it's calculated
A fifth-degree polynomial in bodyweight (kg) produces a coefficient, which you multiply by your total (kg):
Wilks score = coefficient × total (kg)
a-f are the published Wilks 2020 coefficients, separate sets for men and women; the 2020 revision uses 600 in the numerator (the original 1994 formula used 500 with a different coefficient set). Sourced from Wikipedia's "Wilks coefficient" article and cross-checked against multiple independent Wilks-2 calculator implementations.
Worked example: male, 90 kg bodyweight, 500 kg total
Coefficient at 90 kg: 0.766996. Score: 0.766996 × 500 = 383.50. Enter male, 90 kg, and 500 kg above and the tool shows the same number.
Frequently Asked Questions
What's the difference between Wilks and Wilks 2020?
Wilks 2020 (sometimes called Wilks-2) is a March 2020 rebalancing of Robert Wilks' original 1994 coefficients, meant to better align men's and women's scores and smooth out distortions at the very light and very heavy bodyweight classes. This calculator uses the 2020 coefficients -- an older "classic Wilks" score from the same total and bodyweight will come out slightly different.
Is a higher Wilks score always better?
Within the same scoring system, yes -- that's the entire point of Wilks: to let a 60 kg lifter's total and a 140 kg lifter's total be compared on one scale. Just don't compare a Wilks-2020 number to an old classic-Wilks number; they're not on the same scale.
Should I enter one lift or my full total?
Wilks was built to score a full powerlifting total (squat + bench + deadlift). You can enter a single lift if you want a rough comparison point, but it wasn't designed or validated for that use.
Wilks or DOTS -- which should I use?
DOTS is the newer formula and is what USA Powerlifting now uses for its own best-lifter scoring, in part because it doesn't distort as much at the bodyweight extremes that Wilks does. Wilks is still the more widely recognized name outside the US federation. See the DOTS calculator to compare both on the same total.
