Wilks Score Calculator
Use the Wilks Score Calculator to compare powerlifting performance across different body weights. By entering your gender, total lifted weight, and bodyweight, this tool estimates your Wilks coefficient — a standardized score that allows lifters of all sizes to be fairly compared. Widely used in powerlifting competitions and training analysis.

Where:
- $$T$$ = Total weight lifted (kg)
- $$W$$ = Bodyweight (kg)
- $$a$$,$$b$$,$$c$$,$$d$$,$$e$$,$$f$$ are gender-specific coefficients
Men’s coefficients:
- $$a$$ = -216.0475144
- $$b$$ = 16.2606339
- $$c$$ = -0.002388645
- $$d$$ = -0.00113732
- $$e$$ = 7.01863E-06
- $$f$$ = -1.291E-08
Women’s coefficients:
- $$a$$ = 594.31747775582
- $$b$$ = -27.23842536447
- $$c$$ = 0.82112226871
- $$d$$ = -0.00930733913
- $$e$$ = 4.731582E-05
- $$f$$ = -9.054E-08
The Wilks score is a strength standard used in powerlifting to normalize lifted weight relative to body weight, allowing fair competition between lifters of different sizes. It’s commonly used in federations like IPF and for training progress tracking. While newer formulas like IPF GL exist, the classic Wilks formula is still widely recognized and used. The higher your Wilks score, the more impressive your lift is for your size.
