Wilks Score Calculator: Compare Powerlifting Strength Across Weight Classes
Calculate your Wilks score to fairly compare powerlifting performance regardless of bodyweight. Get instant strength rankings and competition standards.
What is the Wilks Score?
The Wilks score is a coefficient used in powerlifting to compare the relative strength of lifters across different weight classes. Developed by Robert Wilks, this formula normalizes total weight lifted relative to bodyweight, creating a fair comparison between lighter and heavier lifters.
The Wilks coefficient addresses the natural advantage that heavier lifters have in absolute strength by giving lighter lifters a higher coefficient per kilogram lifted. This creates a level playing field where a 60kg lifter can be fairly compared to a 120kg lifter based on their relative strength performance.
How to Calculate Wilks Score
The Wilks score is calculated using the formula: Wilks Score = Total Weight Lifted × Wilks Coefficient
The Wilks coefficient is determined by a complex polynomial equation that considers your bodyweight and gender:
Wilks Coefficient = 500 / (a + b×BW + c×BW² + d×BW³ + e×BW⁴ + f×BW⁵)
Where BW is bodyweight in kilograms, and a, b, c, d, e, f are gender-specific constants derived from powerlifting competition data.
Wilks Score Standards and Rankings
Men's Standards
- Elite: 400+ (World-class strength)
- Advanced: 350-399 (Competitive level)
- Intermediate: 300-349 (Strong lifter)
- Novice: 250-299 (Developing strength)
- Beginner: <250 (Starting out)
Women's Standards
- Elite: 350+ (World-class strength)
- Advanced: 300-349 (Competitive level)
- Intermediate: 250-299 (Strong lifter)
- Novice: 200-249 (Developing strength)
- Beginner: <200 (Starting out)
Using Wilks Score for Training
Your Wilks score serves as an excellent benchmark for tracking strength progress over time. Unlike absolute numbers, Wilks score accounts for bodyweight changes, making it ideal for:
- Comparing your strength to other lifters regardless of weight class
- Setting realistic strength goals based on your current level
- Tracking progress during weight cuts or bulking phases
- Determining competitive readiness for powerlifting meets
Limitations and Modern Alternatives
While Wilks remains widely recognized, newer formulas like IPF GL Points and Dots have been developed using more recent competition data. These newer systems may provide more accurate comparisons, especially at the extremes of bodyweight ranges.
However, Wilks score remains valuable for historical comparison and is still used by many lifters and coaches as a familiar strength standard. It provides a good general indication of relative strength performance.
