DOTS Score Calculator
Compare powerlifting strength across all body weights using the official DOTS formula — adopted by the IPF to replace Wilks.
DOTS Score Calculator
Official DOTS formula — male & female
Applies to both fields
DOTS uses a sex-specific 4th-degree polynomial fitted to large competition datasets. It corrects for biases present in the original Wilks formula and remains accurate at very light and very heavy body weights.
Formula: Total (kg) × (500 / f(bw)), where f(bw) is a 4th-degree polynomial with sex-specific constants.
How the DOTS Formula Works
The DOTS score multiplies your total by a body-weight coefficient derived from a sex-specific 4th-degree polynomial. The curve is fitted separately for men and women, correcting for biological differences in muscular potential across the weight spectrum.
Male constants: a = −0.000001093, b = 0.0007391293, c = −0.1918759221, d = 24.0900756, e = −307.75076
Female constants: a = −0.0000010706, b = 0.0005158568, c = −0.1126655495, d = 13.6175032, e = −57.96288
DOTS Score Classification Table
| DOTS Score | Level | Description |
|---|---|---|
| Below 200 | Beginner | First steps in the sport |
| 200 – 300 | Novice | Building a foundation |
| 300 – 400 | Intermediate | Competitive at local meets |
| 400 – 450 | Advanced | Regional-level performance |
| 450 – 500 | Elite | National competition level |
| 500+ | World Class | International competition |
DOTS vs. Wilks: Key Differences
Both normalize a total for body weight but use different polynomial models. The main practical differences:
- DOTS uses updated regression data and is unbiased across the full body weight range
- Wilks 2020 was also recalibrated and produces similar scores for most lifters (60–105 kg)
- For IPF-affiliated competitions, DOTS or IPF GL Points are the official ranking metrics
- For general cross-federation tracking, either works — pick one and stick with it
