Wilks and DOTS Score Calculator (Powerlifting Coefficients)
Your powerlifting total scaled by bodyweight, as a Wilks score and as a DOTS score, so lifters of different sizes can be compared.

The dashed line marks the value you entered.
What this tool does
A heavier lifter lifts more in absolute terms, so federations multiply the total by a coefficient that falls as bodyweight rises. Wilks, from the 1990s, was the standard for decades; DOTS, introduced in 2019, uses a fourth-degree polynomial fitted to more recent data and is now common in meets and apps. Both are 500 ÷ a polynomial of bodyweight in kilograms, with separate coefficients for men and women, and the bodyweight is held between 40 kg and 200 kg (150 kg for women) because the polynomials fail outside that range.
Formula
score = total × 500 ÷ (a + b x + c x² + d x³ + e x⁴ [+ f x⁵]) · x = bodyweight in kg · Wilks (original 1990s coefficients) and DOTS (2019) use different polynomials
