What This Calculator Measures
The Wilks Score is a coefficient used in powerlifting to compare the relative strength of lifters across different body weight classes. A higher Wilks Score indicates greater pound-for-pound strength. It has been the standard comparison metric in the International Powerlifting Federation (IPF) for decades.
How It Works
The Wilks formula applies a polynomial coefficient to your powerlifting total (squat + bench + deadlift):
**Wilks = Total x (500 / (a + bx + cx² + dx³ + ex⁴ + fx⁵))**
Where x is body weight in kilograms and a-f are sex-specific published coefficients. The formula normalizes totals so that a 60 kg lifter and a 120 kg lifter can be compared fairly.
| Wilks Score | Classification |
|---|---|
| Below 300 | Beginner |
| 300 - 399 | Intermediate |
| 400 - 499 | Advanced |
| 500+ | Elite |
Limitations
•The Wilks formula has been criticized for slightly favoring heavier lifters at extreme body weights.
•The DOTS and GL coefficients were developed as more modern alternatives that may provide fairer comparisons at the extremes of body weight.
•Wilks only applies to the powerlifting total (squat, bench, deadlift). It does not apply to individual lifts or other sports.
•The formula uses separate coefficients for male and female lifters. It is not designed for cross-sex comparisons.
