Free Wilks calculator for powerlifting. Get your relative strength score from body weight, squat, bench, and deadlift via Wilks and Wilks-2.
Estimates only. Training loads, paces and body-composition figures vary a lot between individuals, and none of this is medical or coaching advice. Talk to a professional before changing how you train.

The Wilks coefficient is the original standard for comparing powerlifting performance across different body weights and genders. Enter your squat, bench press, and deadlift to calculate your Wilks score and see how you compare to lifters worldwide.
The Wilks coefficient was developed by Robert Wilks and has been used in powerlifting since 1994. It uses a 5th-degree polynomial equation with gender-specific coefficients to normalize strength across body weights. The original formula was updated in 2020 (Wilks-2) with recalibrated coefficients based on modern competition data.
Wilks Formula
Compare scores with lifters from before 2019 when IPF used Wilks.
Some federations still use Wilks as their official scoring system.
Track your relative strength improvement over years of training.
Set classification targets: Class I (400+), Master (450+), Elite (500+).
Wilks has been the benchmark for powerlifting comparison for nearly 30 years.
Fair comparison between lifters of vastly different body weights.
Separate coefficients allow meaningful comparison between male and female lifters.
Monitor your relative strength as body weight changes over your lifting career.
Sub-Elite: under 300, Class III: 300-350, Class II: 350-400, Class I: 400-450, Master: 450-500, Elite: 500-550, World Class: 550+. Most competitive lifters aim for 400+ to be considered advanced.
Wilks-2 (2020) updated the original coefficients using modern competition data. It addresses criticisms that the original favored certain weight classes. Wilks-2 uses 600 as the base instead of 500 and has recalibrated polynomial coefficients.
DOTS (2019) is used by several federations such as USAPL and is considered more balanced across weight classes; the IPF uses its own GoodLift points. Wilks is still valid for historical comparisons and federations that haven't switched. All are useful measures of relative strength.
The original Wilks formula has been criticized for favoring very light and very heavy lifters at the extremes. Wilks-2 attempted to address this, though debates continue. Most criticism applies to extreme weight classes (under 52kg or over 120kg).
