Strength Score Calculator
Score your powerlifting total with the Wilks coefficient to compare lifters across body weights, plus your strength relative to body weight. Calculates in your browser.
Wilks score
-
Show the math
The Wilks coefficient normalises a total across body weights:
Wilks score = coefficient(bodyweight) × total lifted
The coefficient is a polynomial in body weight, larger for lighter lifters because lifting a big total at low body weight is harder pound-for-pound. Relative strength is simply your lift divided by your body weight.
What this does
A strength score calculator scores your powerlifting total with the Wilks coefficient, letting lifters of different body weights be compared fairly, plus your strength relative to body weight.
How it works
The Wilks coefficient, based on your body weight, multiplies your total lifted so lifters of different sizes compare on a level field. Lighter lifters get a larger coefficient because a big total at low body weight is harder pound-for-pound.
How to use it
- Enter your body weight and sex.
- Enter your total (or a single lift).
- Read your Wilks score.
- Compare it against other lifters.
Understanding your result
A higher Wilks score is better. Entering a single lift instead of a total shows its relative-strength multiple of your body weight.
Example
An 80 kg male lifter with a 500 kg total scores roughly 330 Wilks points.

Frequently asked questions
What is a Wilks score?
It is a coefficient based on your body weight that multiplies your total lifted, letting lifters of different sizes be compared fairly. Higher is better.
What total should I enter?
Usually your best squat + bench press + deadlift. You can also enter a single lift to see its relative-strength multiple of your body weight.
Is a higher or lower body weight better?
Lighter lifters get a larger coefficient because lifting a big total at low body weight is harder pound-for-pound. The formula balances this across the field.
