Is a Wilks score of 300 good?
A Wilks score of 300+ is considered elite for most lifters, indicating exceptional relative strength. Scores of 200-250 are advanced/competitive, 100-150 is intermediate/experienced, and below 100 is beginner.

What this calculator does
The Wilks score calculator is a specialized tool for powerlifters and strength athletes that normalizes their lifting performance across different body weights. It allows fair comparison between lifters of different sizes by calculating a strength coefficient. Created by Robert Wilks, this formula uses a sophisticated algorithm that adjusts for diminishing returns in strength as bodyweight increases. The resulting score enables international powerlifting competitions to rank athletes equitably and helps individual lifters track their progress relative to their weight class.
How it works
The Wilks formula calculates a coefficient based on your body weight, then multiplies that coefficient by your lifted weight to produce a normalized score. The formula accounts for the biomechanical reality that lighter lifters typically have greater relative strength compared to their body weight. The calculation applies different coefficients for men and women because of differences in muscle mass distribution and strength potential. Your Wilks score represents what you 'should' be able to lift if you were a theoretical 'average' human.
Formula
Wilks Coefficient = 500 ÷ (a + b×bodyweight + c×bodyweight² + d×bodyweight³ + e×bodyweight⁴ + f×bodyweight⁵). For men and women: specific constants derived from historical data. Wilks Score = Coefficient × Total Weight Lifted. Score of 300+ is elite, 200-250 is advanced, 100-150 is intermediate.
Tips for using this calculator
- Your Wilks score combines all three powerlifting lifts (squat, bench, deadlift)—improvements in any lift will increase your total
- A heavier bodyweight increases your absolute strength potential but decreases your Wilks score due to the formula's adjustment
- Track your Wilks score over time rather than focusing solely on total pounds lifted—it better reflects your actual strength progress
- Compare your Wilks score to others in your weight class and gender to understand your competitive standing
- Use Wilks scores to identify weak points: if your total is respectable but Wilks score is low, you may need to optimize body composition
Frequently asked questions
Why does a heavier lifter have a lower Wilks score than a lighter one?
The Wilks formula penalizes higher body weights because it accounts for the biomechanical advantage of size. A 200-pound lifter who deadlifts 500 pounds has a lower Wilks score than a 150-pound lifter deadlifting 450 because the lighter lifter demonstrates greater strength relative to body size.
Should I change my bodyweight to improve my Wilks score?
Not necessarily. Your ideal weight depends on your goals. Gaining muscle increases absolute strength but adds bodyweight which penalizes the Wilks formula. Generally, the best strategy is to maximize strength gains relative to bodyweight through progressive training.
