Wilks 2020 (Wilks2) — updated coefficients
Applies to both fields
The Wilks score is the most recognized relative strength metric in powerlifting. It normalizes your total for body weight so that a 60 kg lifter and a 130 kg lifter can be compared on equal footing, regardless of weight class.
Uses the 2020 recalibration (Wilks2) fitted to 100,000+ competition results — fixing biases in the original formula at extreme body weights.
What Is the Wilks Score?
The Wilks score solves a fundamental problem in powerlifting: how do you fairly compare a 60 kg lifter totaling 400 kg against a 130 kg lifter totaling 550 kg? Raw totals are meaningless across weight classes — the Wilks score puts everyone on the same scale.
Robert Wilks developed the formula in the 1990s by running polynomial regressions on elite competition data. The resulting coefficient — unique to each body weight and sex — turns any total into a normalized score where higher always means stronger, no matter the weight class.
Wilks Score Classifications
Use these benchmarks to understand where you currently stand:
| Wilks Score | Level | What It Means |
|---|---|---|
| Below 200 | Beginner | Just getting started in the sport |
| 200 – 299 | Novice | Training consistently, making fast progress |
| 300 – 399 | Intermediate | Competitive at local and regional meets |
| 400 – 499 | Advanced | Top 10% of competitive powerlifters |
| 500 – 549 | Elite | National-level competitors |
| 550+ | World Class | Top-tier international athletes |
Wilks 2020 vs. Original Formula
The original Wilks formula served the sport for decades, but research showed systematic bias — it slightly favored lighter weight classes and became less accurate at extreme body weights. The 2020 recalibration (called Wilks2) used more than 100,000 competition results to re-derive the polynomial constants.
For lifters in the 60–100 kg range, the differences are minimal (±5 points). At very light or very heavy body weights, the 2020 formula is noticeably more fair. This calculator uses Wilks 2020 exclusively.
How to Improve Your Wilks Score
Your Wilks score grows when your total increases faster than your body weight. Two practical approaches:
- Increase your total without gaining weight — focus on technique, programming, and strength. Ideal when you're already at your natural body weight ceiling for your class.
- Cut to a lower weight class — if you're carrying excess body fat, a strategic cut can significantly boost your Wilks by reducing the denominator without reducing the numerator (your total).
Most intermediate lifters improve Wilks fastest by adding to their total first. Weight class strategy becomes relevant once raw strength gains slow down.
