Understanding the Wilks Formula
The Wilks formula was developed by Robert Wilks in 1994 to compare powerlifters of different bodyweights on a single scale. It uses a fifth-order polynomial fit to historical performance data, producing a coefficient that adjusts your total.
When Wilks Falls Short
Wilks has known biases: it tends to favor mid-heavyweight lifters and undervalue performance at the weight extremes. Modern alternatives like DOTS and IPF GL points address these issues. Serious competitive lifters often calculate all three.
About the Calculation
This tool uses the original 1994 Wilks coefficients. The 2020 "Wilks 2" update uses revised numbers but has seen limited federation adoption. If you're preparing for a specific meet, check which formula your federation uses.
