Calculate your DOTS score for powerlifting. DOTS is a modern bodyweight-adjusted formula designed to reduce some Wilks-era bias at very light and very heavy bodyweights.
DOTS is a bodyweight-adjustment formula introduced in 2019 as an alternative to Wilks.
It converts a powerlifting total and bodyweight into a single score so performances can be compared across classes. DOTS scores are scaled to stay in a familiar range for lifters who already know Wilks-style numbers.
Enter your bodyweight and total to calculate a DOTS score for comparison.
It is useful for comparing totals across bodyweights with the same scoring system used in many modern meets and databases. As with any coefficient formula, it is a reference score rather than a complete picture of lifting performance.
DOTS Score = Total × 500 / (A × BW⁴ + B × BW³ + C × BW² + D × BW + E) Male coefficients: A = -0.0000010930, B = 0.0007391293, C = -0.1918759221, D = 24.0900756, E = -307.75076 Female coefficients: A = -0.0000010706, B = 0.0005158568, C = -0.1126655495, D = 13.6175032, E = -57.96288
Result: DOTS Score: 372.6
At 82.5 kg bodyweight (male), the DOTS coefficient produces a score of 372.6, compared with a Wilks score of 368.4 for the same total. The gap is small at this middle bodyweight but can widen at lighter or heavier extremes.
Powerlifting has used several scoring systems: the Schwartz/Malone formula (1970s–1990s), the Wilks formula (1997–2019), and now DOTS and IPF GL as modern alternatives. Each iteration improved upon statistical weaknesses in the previous model as more competition data and better analytical methods became available.
While Wilks uses a 5th-degree polynomial in the denominator, DOTS uses a 4th-degree polynomial with coefficients derived from a larger, more recent dataset. The lower polynomial degree reduces overfitting at extreme bodyweights, which was the primary source of Wilks bias. This means DOTS is less likely to produce anomalous scores at the boundaries.
For a 60 kg male with a 400 kg total, Wilks gives approximately 369 while DOTS gives approximately 355 — a 14-point difference that could affect best lifter awards. Conversely, a 120 kg male with a 700 kg total might see Wilks at 430 and DOTS at 440. The direction of difference reverses depending on bodyweight.

DOTS addresses known biases in the Wilks formula, particularly at extreme bodyweights. For lifters in the 70–100 kg range, both scores are very similar. If you compete at very light or very heavy bodyweights, DOTS provides a fairer comparison. Neither is definitively "better" — they're tools for different contexts.
DOTS is used by the USPA (United States Powerlifting Association), some WRPF affiliates, and several other federations. The IPF uses its own GL Points system. Many regional and national federations have adopted DOTS as their primary or secondary scoring system since 2019.
Rough shorthand ranges often cited by lifters are: under 200 beginner, 200–300 intermediate, 300–400 advanced, 400–500 elite, and 500+ world-class. Treat them as broad heuristics rather than federation standards.
Statistical analysis showed that the Wilks formula, derived from 1990s data, systematically overvalued super-heavyweight lifters and undervalued light-weight lifters. As the sport evolved and more data became available, a new formula was needed. Tim Cooke developed DOTS using modern regression techniques on updated competition data.
Yes. Like Wilks, the DOTS coefficient can be applied to any individual lift (bench-only, deadlift-only, etc.) or to the powerlifting total. The coefficient is bodyweight-dependent, not lift-dependent. Multiply the lift weight by (500 / denominator) just like you would for a total.
The male and female DOTS coefficients use different polynomial constants that model the gender-specific relationship between bodyweight and strength potential. Female coefficients produce higher multipliers at equivalent bodyweights to normalize for the physiological differences in muscle mass and hormonal profiles.
