🏆 Wilks Score Calculator
Enter your bodyweight and total lifted to calculate your Wilks score — used to compare strength across different bodyweights.
A fifth-order polynomial in bodyweight
Wilks divides 500 by a quintic curve fitted to bodyweight, then multiplies your total by the result. Men and women get entirely separate coefficient sets:
coefficient = 500 / (a + bx + cx² + dx³ + ex⁴ + fx⁵)
score = total lifted × coefficient (x = bodyweight in kg)An 83 kg man totalling 400 kg gets a coefficient of 0.6675 and a score of 267.00. The same 400 kg at 66 kg bodyweight scores 314.08, and at 100 kg only 243.44 - that spread is the whole point of the formula.
Using it properly
- Total means all three lifts. Squat plus bench plus deadlift, best successful attempt at each. A single lift produces a number that compares to nothing.
- Kilograms only. There is no lb option, so a 900 lb total goes in as 408.2 kg. Bodyweight is capped at 30-220 kg.
- The curve is steepest at the light end. Going 66 kg to 76 kg drops the coefficient by 0.079; 110 kg to 120 kg drops it by 0.014. Weight classes matter far more to light lifters.
Frequently asked questions
What is a good Wilks score?
As rough markers, 300 is a solid intermediate, 400 is competitive at national level and 500 sits near world class. Under 200 is early days, not a verdict.
How is a Wilks score calculated?
Your bodyweight in kilos is put through a five-term polynomial, 500 is divided by the answer, and your total is multiplied by that coefficient. At 83 kg the coefficient is 0.6675.
Is Wilks still the standard?
Not in the IPF, which switched to GL points in 2020. It stays common in gyms and other federations because decades of results are expressed in it.
