Wilks Calculator

The Wilks score normalizes powerlifting totals so lifters of different bodyweights can be compared.

How the Math Works

The Wilks formula normalizes strength across different bodyweights using a polynomial equation. It calculates Wilks Score = 500 ÷ polynomial(bodyweight) × total, where 'total' is the sum of squat, bench press, and deadlift. The polynomial adjusts for bodyweight by applying a standardized mathematical function, ensuring that smaller and larger athletes are compared fairly. This formula accounts for natural strength differences tied to size, making it a reliable metric for cross-weight-class comparisons.

Practical Applications

To use the Wilks Calculator, input your bodyweight in kilograms or pounds (depending on your region) and your total lifted weight (sum of your three competition lifts). The calculator applies the polynomial formula to generate a standardized score, allowing you to compare your performance against lifters of all sizes. This is especially useful in powerlifting meets, where athletes compete in weight classes, as it provides a universal benchmark to assess relative strength regardless of your frame.

Day-to-Day Use

The Wilks Calculator helps lifters objectively measure progress and set realistic goals. By tracking your Wilks Score over time, you can gauge improvements in strength efficiency relative to your bodyweight, even as you gain or lose weight. Coaches and athletes also use it to design personalized training programs, optimizing performance for each individual's physique. Beyond competitions, it serves as a motivational tool, showing how your strength compares to peers and encouraging targeted, data-driven fitness journeys.

Worked example

80 kg male, 500 kg total → ~330 Wilks.
