DOTS Score Calculator
Written by Thierno Sadou Diallo, formula verified per our methodology • Last checked on 9/9/2026
The DOTS score is calculated with total lifted × 500 ÷ a polynomial of body weight, with coefficients specific to each sex. For an 80 kg man with a 500 kg total, the DOTS score is about 344.8.
Explanation
The DOTS score is a powerlifting formula designed to fairly compare the performance of athletes with very different body weights, much like a 60 kg athlete and a 140 kg athlete can't be compared directly on their total lifted in kilograms alone. The score divides the total lifted (the sum of the squat, bench press, and deadlift in competition) by a fourth-degree polynomial of body weight, with separate coefficients for men and women, statistically calibrated from thousands of real competition results. DOTS was developed to succeed the Wilks score, older (1994) and increasingly criticized for fairness gaps across weight classes, especially at the extremes of the distribution; several powerlifting federations have since adopted DOTS or related formulas (GL/Goodlift, IPF) as the official reference for open-class rankings. No formula of this kind is perfectly neutral across all body weights: comparative statistical studies show that each formula (Wilks, DOTS, IPF, GL) retains slight residual biases depending on the weight class and sex considered, which explains why several competing formulas currently coexist rather than a single, definitive consensus. The total lifted to enter may already be known or estimated from a 1RM calculator on each of the three competition lifts.
Example: an 80 kg man, 500 kg total
Inputs
Total lifted: 500 kg. Body weight: 80 kg. Sex: man.
Calculation
The body-weight polynomial (with the male coefficients) gives about 725.2 in the denominator. DOTS score = 500 × 500 ÷ 725.2 ≈ 344.8.
Result
This 500 kg total at 80 kg body weight gives a DOTS score of about 344.8.
Frequently asked questions
What is the difference between the DOTS score and the Wilks score?
Both formulas serve the same purpose (comparing relative strength between athletes of different weights) but use different coefficients and calibration data: the Wilks score dates from 1994, while DOTS was developed more recently from more extensive competition data, aiming to correct certain statistical biases observed in the Wilks formula for some weight classes.
Is the DOTS score the same as the IPF or GL (Goodlift) score?
No, these are distinct formulas, each with its own coefficients and its own statistical calibration method, even though all aim for the same goal of fair comparison across body sizes. Comparative studies show each formula retains slightly different residual biases depending on weight class, which is why several competing formulas still coexist today rather than a single standard.
Does this score account for the athlete's age?
No, the base DOTS score only considers body weight, sex, and total lifted, with no adjustment for age. Some federations apply an additional multiplier by age bracket for masters categories (older athletes), but that factor is separate from the DOTS calculation itself and isn't covered by this calculator.
