Wilks Score Calculator: Powerlifting Strength Comparison
The Wilks score is the most widely used method for comparing powerlifting performances across different bodyweight classes and between male and female athletes. Unlike raw totals (which favor heavier lifters) or simple bodyweight ratios (which favor lighter lifters), the Wilks formula uses a polynomial equation fitted to world record data across all weight classes to produce a fair relative strength comparison.
The Three Powerlifts
Competitive powerlifting consists of three lifts: the squat, bench press, and deadlift. The powerlifting total is the sum of each lifter's best successful attempt in all three lifts. The total is what gets entered into the Wilks formula.
Using Wilks for Training Goals
The Wilks score is valuable for goal-setting in training. Working toward specific Wilks milestones (250 to 300 to 350) provides more meaningful targets than arbitrary weight goals because it accounts for your changing bodyweight over time. If you gain muscle and bodyweight while improving your total proportionally, your Wilks score remains stable - reflecting true strength improvement vs. mass gain. Use the Strength Standards Checker to see where each individual lift ranks.
Alternative Scoring Systems
- DOTS: Newer system used by World Para Powerlifting, considered more accurate at extreme bodyweights
- IPF GL Points: Official scoring system of the International Powerlifting Federation, updated more recently than Wilks
- Allometric Scaling (ALS): Research-based approach using body mass to the power of 2/3
