Wilks Calculator
Compare powerlifting totals across body weights with the Wilks coefficient (Wilks 2020 formula) — your total times the coefficient for your body weight. An exact calculation from the published coefficients.
Your Wilks score (2020 formula)
400.82
Total 500 kg × coefficient 0.8016 = 400.82 Wilks points. A higher score means a stronger total for your body weight.
| Wilks coefficient | 0.8016 |
| Total lifted | 500 kg |
| Wilks score | 400.82 |
Rough guide on the 600-point scale: a Wilks 2020 score of 350 is a solid trained lifter, 450 is advanced, and 500+ is elite-level. The formula is designed for body weights between 40 and 200.95 kg (men) or 40 and 150.95 kg (women); outside that range the coefficient is unreliable.
Formula & source — Wilks 2020 formula (Powerlifting Australia, February 2020)
Wilks score = total × 600 ÷ (a + b·bw + c·bw² + d·bw³ + e·bw⁴ + f·bw⁵), with the 2020 coefficients: men a=47.46178854, b=8.472061379, c=0.07369410346, d=−0.001395833811, e=7.07665973×10⁻⁶, f=−1.20804336×10⁻⁸; women a=−125.4255398, b=13.71219419, c=−0.03307250631, d=−0.001050400051, e=9.38773881×10⁻⁶, f=−2.33346139×10⁻⁸. This is the 2020 revision — the classic 1994 Wilks formula used a 500 numerator and different coefficients, so the two scores are not comparable. An exact calculation from the published coefficients.
