DOTS Score Calculator
Calculate your DOTS score — the modern replacement for Wilks in powerlifting.
Compare strength across body weights with the updated formula.
DOTS Formula:
DOTS = Total (kg) × 500 / (A × bw⁴ + B × bw³ + C × bw² + D × bw + E)
Where:
- Total = your combined squat, bench press, and deadlift in kilograms
- bw = your body weight in kilograms
- A, B, C, D, E = polynomial coefficients that differ for male and female lifters. These constants were derived from statistical analysis of competition data to create a fair comparison curve across all body weights.
The DOTS formula normalizes your total by dividing it by a body-weight-dependent polynomial. This produces a score that allows fair comparison between lifters of very different body weights.
Why DOTS replaced Wilks: The DOTS system was adopted by the International Powerlifting Federation (IPF) in 2019 because it provides more accurate comparisons across all body weight classes. The older Wilks formula (from 1994) tended to favor certain weight classes, particularly undervaluing very light and very heavy lifters. DOTS corrects this bias using a 4th-degree polynomial instead of the 5th-degree polynomial used by Wilks.
DOTS Score Ranges:
| Score | Level | What It Means |
|---|---|---|
| Under 200 | Beginner | New to powerlifting |
| 200-300 | Novice | Developing consistent technique |
| 300-400 | Intermediate | Solid strength base |
| 400-475 | Advanced | Competitive at regional level |
| 475-550 | Elite | National-level competitor |
| 550+ | World class | International-level strength |
Practical Example: A male lifter weighing 82 kg with a total of 520 kg (200 squat + 130 bench + 190 deadlift): The polynomial denominator for 82 kg evaluates to approximately 675. DOTS = 520 x 500 / 675 = 385 (Intermediate level) To reach Advanced (400), this lifter would need a total of about 540 kg.
Tips:
- Enter your best competition lifts, not gym PRs — competition standards require deeper squats and paused bench presses
- If you only know your lifts in pounds, the calculator converts automatically
- DOTS and Wilks scores are usually close for lifters between 65-100 kg, but diverge more at extreme body weights
- Track your DOTS score over time to measure progress independent of body weight changes
