A Wilks score is a single number that lets you compare powerlifting strength fairly between lifters of different bodyweights. A 60 kg lifter and a 100 kg lifter cannot be ranked by their raw total alone, because heavier people can usually move more weight. The Wilks coefficient corrects for that: it scales your total lifted up or down based on your bodyweight, so pound-for-pound strength is what gets measured. This calculator takes your sex, bodyweight and total lifted and returns your Wilks coefficient and your Wilks score.
How the Wilks score is calculated
The method comes from a formula published by Robert Wilks. Your bodyweight in kilograms is fed into a fifth-order polynomial with six fixed constants that differ for men and women. The result is divided into 500 to produce your Wilks coefficient, a multiplier that is largest for the lightest lifters and shrinks as bodyweight rises. Your Wilks score is simply that coefficient multiplied by your total lifted.
For example, a man weighing 90 kg has a Wilks coefficient of about 0.638. If his combined squat, bench press and deadlift add up to a 600 kg total, his Wilks score is 0.638 multiplied by 600, or roughly 383. A lighter 75 kg man with the same 600 kg total would have a higher coefficient near 0.713 and a score around 428, which is the whole point: the same raw total counts for more when you carry less bodyweight.
What is a good Wilks score?
As a rough guide, a score under 200 is beginner territory, 200 to 300 is novice, 300 to 400 is a solid intermediate, 400 to 500 is advanced, and 500 or more is elite competitive level. The same bands apply to men and women because the coefficients already account for the difference. These are starting reference points, not strict rules, and a single lift or a partial total will naturally score lower than a full three-lift total.
Use the score to track your own progress over months and to compare yourself with training partners across weight classes. Because it rewards strength relative to bodyweight, your Wilks can climb even when your raw total stays flat, simply by getting leaner, and it can drop if you gain bodyweight faster than you gain strength.
Wilks and the newer formulas
This calculator uses the original Wilks coefficient, the version that ranked lifters for decades and is still the most widely recognised strength-comparison score. Several federations have since adopted updated systems such as Wilks 2 and the IPF GL points, which retune the curve with more recent data. The numbers differ slightly, but the idea is identical, and the original Wilks remains the most useful common language for comparing pound-for-pound strength.

Frequently Asked Questions
It multiplies your total lifted by a coefficient based on bodyweight, so a 60 kg and a 100 kg lifter can be compared fairly.
Roughly 300 is a solid intermediate, 400+ is advanced, and 500+ is elite competitive territory.
Usually your combined best squat, bench press and deadlift, but you can use any total you want to score.
Many federations moved to newer coefficients, but Wilks remains the most widely recognised strength-comparison score.
