How Our Powerlifting Calculations Work (DOTS, Wilks, IPF GL)

Short answer: every score on this site is calculated in your browser using the published formulas: DOTS (Tim Konertz, BVDK, 2019), Wilks (1995), Wilks-2 (2020) and IPF GL points (IPF, valid from 1 May 2020). This page lists the exact formulas and coefficients, shows worked examples, and explains why different calculators can give slightly different results.

What DOTS stands for

DOTS stands for Dynamic Objective Team Scoring. It was developed in 2019 by Tim Konertz of the German powerlifting federation (BVDK) to compare lifters of different bodyweights fairly. It converts your total (squat + bench press + deadlift, in kilograms) into a bodyweight-adjusted score.

The DOTS formula

DOTS = total (kg) × 500 ÷ (a·BW⁴ + b·BW³ + c·BW² + d·BW + e)

BW is bodyweight in kilograms. Bodyweight is limited to 40–210 kg for men and 40–150 kg for women before the formula is applied, as in the OpenPowerlifting reference implementation.

Woman63 kg350 kg376.43375.8976.57

For the man: the DOTS coefficient at 90 kg is 0.64660, so 600 × 0.64660 = 387.96. You can check these numbers in our DOTS calculator.

Wilks and Wilks-2

Wilks = total × 500 ÷ (a + b·BW + c·BW² + d·BW³ + e·BW⁴ + f·BW⁵)

CoefficientMen (1995)Women (1995)

f-1.291 × 10⁻⁸-9.054 × 10⁻⁸

Wilks-2 (2020) uses the same polynomial shape with updated coefficients (men: a = 47.46178854, b = 8.472061379, c = 0.07369410346, d = -0.001395833811, e = 7.07665973070743 × 10⁻⁶, f = -1.20804336482315 × 10⁻⁸; women: a = -125.4255398, b = 13.71219419, c = -0.03307250631, d = -0.001050400051, e = 9.38773881462799 × 10⁻⁶, f = -2.3334613884954 × 10⁻⁸). Use our Wilks calculator to compare both.

IPF GL points

IPF GL points = total × 100 ÷ (A − B · e^(−C · BW))

Pounds and kilograms

All formulas are defined in kilograms. If you enter pounds, we convert with 1 lb = 0.45359237 kg before calculating. Scores are shown to two decimal places.

Why calculators sometimes disagree

Limits of these scores

These calculators are for estimates and training comparisons. Official meet placings are calculated by each federation’s own software and rules. Dots Calculator is independent and not affiliated with the IPF, USA Powerlifting, the BVDK or any other federation.
