Comparing Strength Across Bodyweights, Honestly

A 180 kg total means something very different from a 70 kg lifter than from a 120 kg lifter. Federations solve this with the Wilks coefficient, a published fifth-degree polynomial regression with separate official coefficients for men and women that normalizes a total against bodyweight. This calculator does not attempt to reproduce those official coefficients — getting a regression constant even slightly wrong would silently misrepresent every score run through it. Instead it reports a straightforward, verifiably correct relative-strength ratio: total divided by bodyweight.

The Formula

This calculator's own explanation is explicit about the tradeoff, and the same reasoning applies here:

This is a simplified metric, not the official Wilks score or IPF GL Points — both of which require precisely-published, federation-maintained coefficients that are outside the scope of a general calculator to reproduce accurately. For an official Wilks or GL Points score for competition purposes, use your federation's official calculator.

Where This Calculation Matters

• Quick self-comparison — tracking your own total-to-bodyweight ratio over time is a simple, honest way to see relative strength gains independent of bodyweight changes during a training cycle.
• Weight-class planning — comparing the ratio at your current bodyweight against a target class shows whether cutting or gaining weight would net you a better relative-strength position.
• Training log reference — recording total and ratio together after each meet or heavy training block builds a comparable history.
• Understanding the limits of a simple ratio — this figure is directionally useful but does not correct for the non-linear relationship between bodyweight and strength that Wilks and GL Points are specifically built to model.

How to Use This Calculator

1. Enter your best Squat (kg).
2. Enter your best Bench Press (kg).
3. Enter your best Deadlift (kg).
4. Enter your Bodyweight (kg).
5. Select Calculate to see your total and total-to-bodyweight ratio.
