Wilks Score Calculator
Compare your powerlifting total fairly across bodyweights using the Wilks coefficient — the long-standing standard for ranking lifters of different sizes. This free online fitness & health calculator runs entirely in your browser — no signup, no data sent anywhere.

How It Works (Formula & Method)
Wilks Score = (500 / D) × total, where D is a fifth-degree polynomial of bodyweight using sex-specific coefficients. The math was designed so that elite lifters across weight classes score similarly. Note: in 2020 the IPF replaced Wilks with IPF GL points for international meets, but Wilks remains the most widely-recognized comparison number in lifting culture.
Worked Example
Below is a worked example using the calculator's default values. The same numbers are pre-filled in the form above so you can press Calculate and see the result without typing anything.
Inputs used:
- Bodyweight (kg): 80
- Powerlifting Total (kg): 400
- Sex: male
With these inputs, the calculator computes the metrics shown in the Results panel. Change any value and press Calculate again to see how the result responds — the live widget and the chart both update instantly.
About the Wilks Score Calculator
The Wilks coefficient is a formula used in powerlifting to compare the relative strength of athletes across different bodyweights. Because smaller lifters can move less absolute weight but more relative weight, raw totals are not directly comparable — Wilks scales the total to produce a single number that can be ranked across the entire field.
How to Use This Calculator
Sum your best squat, bench press, and deadlift attempts (your "powerlifting total") in kilograms. Enter that total, your bodyweight in kilograms, and your sex. The calculator returns the Wilks score and a strength category.
Tips & Considerations
- A Wilks of 300+ generally indicates intermediate strength, 400+ advanced, 500+ elite, and 600+ world-class for unequipped lifting.
- For raw lifting, the newer Wilks 2 (Wilks-Robbie) and DOTS scores have replaced the original Wilks at many federations.
- Wilks rewards lighter lifters slightly more than heavier ones at the extremes — be cautious comparing super-heavyweights using Wilks.
Frequently Asked Questions
What is a good Wilks score?
For natural lifters: ~300 is intermediate, ~400 is advanced, ~500 is national-level competitive, ~600+ is elite/world-class.
Is Wilks still used?
It is the most-cited score in casual lifting communities. Competitions increasingly use IPF GL, DOTS, or Wilks 2 — but the original Wilks remains the cultural reference point.
Does Wilks apply to women?
Yes — there are separate coefficients for male and female lifters, designed so a competitive male and competitive female score similarly relative to their own demographic.
How is bodyweight measured?
Use your competition weigh-in weight (usually morning of the meet, often dehydrated). For casual comparison, use your current bodyweight in kilograms.
