Wilks Calculator

The Wilks formula scales a lifter's total by a coefficient based on bodyweight, so a lighter lifter and a heavier lifter with the same score have performed comparably for their size. This uses the classic Wilks coefficients; some federations now use Wilks-2 or IPF points instead.

Wilks score = total (kg) × 500 ÷ (a + b·x + c·x² + d·x³ + e·x⁴ + f·x⁵), where x is bodyweight in kg and a–f are sex-specific coefficients.

The score is a mathematical comparison of a total against bodyweight and reflects only the numbers you enter. It uses the classic Wilks coefficients, whereas some federations now use Wilks-2 or IPF points, so a score here may not match a specific competition's figure. It does not judge technique, equipment or the validity of the lifts.

A 90 kg male with a 600 kg total has a Wilks coefficient of about 0.638, giving a Wilks score of roughly 383.
