Wilks & DOTS Calculator

Score = total × 500 ÷ P(bodyweight), where P is a fifth-order polynomial for Wilks and a fourth-order polynomial for DOTS, with separate coefficients by sex.

Wilks RM (1994); DOTS coefficients (2020), adopted by the IPF and many federations.

Both normalise a total to bodyweight. Wilks penalises the lightest and heaviest lifters more than DOTS, so scores differ most at the extremes.

Comparing across equipment classes (raw vs. equipped) or non-powerlifting lifts — the coefficients assume the squat/bench/deadlift total.

Both convert a powerlifting total into a single number that's comparable across bodyweights, by multiplying your total by a coefficient based on your bodyweight and sex. They let a 60 kg and a 120 kg lifter be ranked fairly against each other.

They use different polynomial curves. The older Wilks formula penalises the very lightest and heaviest lifters a little more, while DOTS — introduced in 2020 — was refitted to modern data and is now the default in many federations. We show both so you can see how you score under each.

Use whichever your federation uses for the meet you care about. If you just want a modern, widely accepted number, DOTS is the current standard. For historical comparisons against older results, Wilks is still common.

Enter it in whichever unit the site is set to; we convert to kilograms internally, since both coefficients are defined for metric bodyweight and totals.

As a rough guide, a score around 300 is a solid intermediate lifter, 400 is advanced, and 500+ is elite or competitive at a national level. The exact thresholds differ by federation and sex.
