The Wilks formulas
Wilks 2020 = total × 600 ÷ (same polynomial, new coefficients)
| a | b | c | d | e | f | |
|---|---|---|---|---|---|---|
| Original Wilks, men | -216.048 | 16.2606 | -0.00238865 | -0.00113732 | 7.01863e-06 | -1.291e-08 |
| Original Wilks, women | 594.317 | -27.2384 | 0.821122 | -0.00930734 | 4.73158e-05 | -9.054e-08 |
| Wilks 2020, men | 47.4618 | 8.47206 | 0.0736941 | -0.00139583 | 7.07666e-06 | -1.20804e-08 |
| Wilks 2020, women | -125.426 | 13.7122 | -0.0330725 | -0.0010504 | 9.38774e-06 | -2.33346e-08 |
Coefficients as listed on Wikipedia’s Wilks coefficient article and the IPF’s 2020 evaluation. For the original formula, bodyweight is clamped to 40–201.9 kg for men and 26.51–154.53 kg for women, as OpenPowerlifting does. Wilks 2020 bodyweights are capped at about 201 kg (men) and 151 kg (women), where the curve turns back up. Because Wilks 2020 uses 600 rather than 500, its scores run about 20% higher — don’t compare the two scales directly.
Which formula does my federation use?
- IPF and its national affiliates — IPF GL points, since 2020 (best-lifter awards).
- Many other federations and OpenPowerlifting’s rankings — DOTS, introduced in 2019.
- Older results, gyms and online rankings — the original Wilks formula is still widely quoted.
Check your meet’s rules — and remember each formula has its own scale, so a “400” in one is not a “400” in another.
