Enter your bodyweight, total lifted weight, gender, and preferred unit system to calculate your Wilks Score — the standard powerlifting metric that lets you compare strength across different body weights and genders.

The Wilks Score (also called the Wilks Coefficient) is a formula used in powerlifting to compare strength between athletes of different body weights and genders. It was developed by Robert Wilks of Powerlifting Australia and produces a single number that normalizes performance across weight classes.
Generally, a Wilks Score under 200 is considered a beginner level, 200–300 is intermediate, 300–400 is advanced, 400–500 is elite, and 500+ is world-class. Most recreational lifters fall in the 150–300 range, while competitive powerlifters typically aim for 350 and above.
The Wilks formula is: Wilks Score = Total Lifted × (500 / (a + b·x + c·x² + d·x³ + e·x⁴ + f·x⁵)), where x is bodyweight in kg and the coefficients a–f differ for males and females. This polynomial function creates a coefficient that adjusts for the diminishing strength gains as bodyweight increases.
Simply enter your bodyweight, the total weight you lifted (typically the sum of your squat, bench press, and deadlift in a powerlifting meet), select your gender and preferred unit (kg or lbs), then click Calculate. Your Wilks Score will be displayed instantly.
Yes. While the Wilks Score was designed for powerlifting totals (squat + bench + deadlift combined), it can also be applied to individual lifts such as just a bench press or deadlift. Simply enter the weight of that single lift as your total.
The Wilks Score is the older, more widely recognized standard and uses a polynomial formula. IPF GL Points (introduced by the International Powerlifting Federation in 2019) use a more statistically updated model based on current world record data. Many federations have transitioned to IPF GL, but Wilks is still widely used for general comparison.
Men and women have different strength-to-bodyweight curves due to physiological differences in muscle mass distribution and hormonal profiles. Using gender-specific coefficients ensures fair comparison within each gender and avoids skewing results when comparing performances.
Yes — a higher Wilks Score indicates greater relative strength adjusted for bodyweight. Two lifters with very different bodyweights can be fairly compared: if lifter A has a Wilks Score of 380 and lifter B has 350, lifter A is considered relatively stronger regardless of their actual body weight.
