Student ProjectHi! I'm a student developer building Calculat in my spare time. I was tired of searching for basic math tools and having to click through 10 spammy popups, loan ads, and cookie trackers.

The Wilks Calculator computes the Wilks coefficient and Wilks score, a standardized powerlifting formula created by Robert Wilks to compare the relative strength of powerlifters across different bodyweight categories and genders.
\text{Coeff} = \frac{500}{a + bx + cx^2 + dx^3 + ex^4 + fx^5}, \quad \text{Wilks Score} = \text{Total (kg)} \times \text{Coeff}Where x is bodyweight in kilograms and a, b, c, d, e, f are gender-specific 5th-degree polynomial coefficients.
Scenario: An 80 kg male powerlifter with a 500 kg three-lift total
Lifter bodyweight: x = 80 kg.
Male polynomial denominator: a + b(80) + c(80²) + d(80³) + e(80⁴) + f(80⁵) = 732.38.
Wilks coefficient: 500 / 732.38 = 0.68270.
Wilks score: 500 kg × 0.68270 = 341.35.
For men: 300+ is competitive at local meets, 400+ is advanced/regional level, 450+ is national level, and 500+ is elite world-class. For women, similar relative benchmarks apply.
Classic Wilks (1997) uses a 500-point numerator. Wilks 2020 uses updated regression coefficients with a 600-point numerator, resulting in scores approximately 20% higher.
While primarily designed for the full three-lift total (Squat + Bench + Deadlift), it is frequently applied to bench-only or push-pull competitions using the single lift weight.
DOTS and IPF GL points are modern alternatives developed to address mathematical flattening at extreme bodyweights. Many federations use DOTS today, but Wilks remains the most recognized historical standard.
