Wilks Calculator
Score and compare powerlifting totals across body weights with the Wilks coefficient.
Wilks score243.44
Wilks coefficient0.6086
The Wilks score normalises a powerlifting total across body weights so lifters of different sizes can be compared. It is total × 500 ÷ P(bw), where P is the men's fifth-degree polynomial in body weight: −216.0475144 + 16.2606339·bw − 0.002388645·bw² − 0.00113732·bw³ + 0.00000701863·bw⁴ − 0.00000001291·bw⁵. A 100 kg lifter with a 400 kg total scores ≈ 243.4. This uses the original (men's) Wilks coefficients; women use a different polynomial.

Questions
What is a Wilks score?
It is a number that adjusts a powerlifting total for body weight so that a lighter and a heavier lifter can be compared. It multiplies the total by a coefficient derived from body weight.
Which coefficients does this use?
It uses the original men's Wilks polynomial. Women's totals use a separate set of coefficients, and a newer Wilks-2 / IPF GL formula exists — this tool reports the classic men's Wilks.
