What is it?
The Wilks Score (developed by Robert Wilks) is a coefficient used in powerlifting to compare total lifted weight across different body weight classes and between male and female lifters. It normalises the total using a polynomial coefficient derived from body weight, enabling fair cross-class comparisons.
How to use
Enter your competition total (Squat + Bench Press + Deadlift) in kilograms, your body weight in kilograms, and select your sex. The calculator applies the Wilks polynomial coefficients (5th-degree polynomial) to produce a single comparable score.
Example scenario
An 80 kg male totals 600 kg. His Wilks Score is approximately 389. A 60 kg male lifting 450 kg might score 393 — very close, showing the formula correctly accounts for the relative strength advantage of lighter athletes.
Pro tip
A Wilks score above 300 indicates a solid competitive level. Scores above 400 are elite amateur territory and 500+ marks world-class. Since 2019, the IPF has officially switched to IPF GL Points, but Wilks remains widely used in untested federations and community lifting for its familiarity and longevity.
