Wilks Score Calculator
Show the math
What Your Result Means
- Wilks Score: A normalized strength metric calculated from your total lift and body weight. Scores above 500 indicate Elite-level strength; 400-500 is Advanced; 300-400 is Intermediate.
- DOTS Score: A modern alternative to Wilks, using an updated polynomial. DOTS tends to be more favorable to lighter lifters and is increasingly used in competitions.
- Classification: Your lifting level (Untrained through Elite) based on Wilks score. The same classification applies across body weights, letting a 120-pound lifter and 300-pound lifter compare results fairly.
- Body Weight (kg): Your weight converted to kilograms, used in the polynomial calculation.
How This Calculator Works
Wilks and DOTS both use a 5th-degree polynomial of body weight to normalize squat + bench + deadlift totals. The formula divides your total by a coefficient derived from the polynomial, offsetting the advantage heavier lifters naturally have. Sex-specific coefficients account for physiological differences.
Quick Questions
What is a good Wilks score?
Above 300 is Beginner-level; 400+ is Intermediate; 500+ is Advanced; 600+ is Elite. For reference, competitive powerlifters typically range 400-600 depending on weight class.
What's the difference between Wilks and DOTS?
DOTS (2019) is a modernized version using updated data and revised coefficients. DOTS is generally more favorable to lighter lifters and is now the standard in many federations.
Why are there separate formulas for male and female?
Physiological differences in muscle mass, leverage, and hormone profiles mean men and women typically have different absolute strength levels at similar body weights. Separate polynomials ensure fair comparisons within each group.
Which score do federations use?
The IPF (International Powerlifting Federation) and most major federations now use DOTS. Some regional meets still use Wilks. Always check your competition's rules.
How is the polynomial calculated?
The polynomial is a 5th-degree fit to historical strength data. Its coefficients were determined by regression to ensure the formula predicts strength fairly across all body weights. Updates to the formula reflect new data or refined methodology.
