What is the Wilks score?
The Wilks score is a formula used in powerlifting to compare lifters across different bodyweight classes. It adjusts your total (squat + bench press + deadlift) for your bodyweight using a polynomial coefficient, producing a single number that can be compared regardless of weight class.
How to use this calculator
- Select your sex and enter your competition bodyweight.
- Enter your total in kg or lbs (squat + bench press + deadlift, best attempts).
- Click Calculate Wilks Score to see your score and coefficient.
The formula
Wilks Score = Total × Coefficient
Coefficient = 500 / (a + bw + cw² + dw³ + ew⁴ + fw⁵)
Where w is bodyweight in kg and the coefficients are:
| Sex | a | b | c | d | |--------|-------------|------------|-------------|--------------| | Male | −216.0475 | 16.2606 | −0.002389 | −0.001137 | | Female | 594.3175 | −27.2384 | 0.8211 | −0.009307 |
How to interpret your result
| Wilks Score | Level | |-------------|-----------------| | < 200 | Beginner | | 200–300 | Intermediate | | 300–400 | Advanced | | 400–500 | Elite | | > 500 | World class |
These thresholds are approximate and vary by federation. Use your Wilks score to track progress over time as your bodyweight changes.
