Compare your strength across weight classes and genders using the most modern coefficient in powerlifting. The DOTS formula provides a fair, mathematical comparison for lifters of all sizes.
What is the DOTS Score Calculator?
The DOTS Score Calculator is a mathematical tool used in the sport of powerlifting to compare the relative strength of lifters across different body weight classes and genders. DOTS stands for Dynamic Objective Team Scoring.
Unlike absolute weight lifted, which naturally favors heavier athletes, the DOTS formula applies a coefficient based on a lifter's body weight. This allows a 60kg female lifter to be compared fairly against a 120kg male lifter. It is currently the primary scoring system used by the World Raw Powerlifting Federation (WRPF) and several other major federations, replacing older systems like the Wilks Score.
The DOTS Formula and Explanation
The DOTS formula is a fourth-degree polynomial equation. The coefficient is calculated by taking 500 and dividing it by the result of the polynomial for a specific body weight.
The General Equation:
Score = Total × (500 / (A*w⁴ + B*w³ + C*w² + D*w + E))
Where w is body weight in kilograms. The constants differ by gender:
| Constant | Male Value | Female Value |
|---|---|---|
| A | -0.000001093 | -0.0000010706 |
| B | 0.000739129 | 0.0005158568 |
| C | -0.191875922 | -0.1126655495 |
| D | 24.0900756 | 13.6175032 |
| E | -307.75076 | -107.010498 |
Efficiency Visualization
The following chart illustrates how the DOTS coefficient changes as body weight increases. Note how the "multiplier" decreases to compensate for the biological advantage of higher mass.

Practical Examples
Example 1: The Lightweight Specialist
A male lifter weighing 75 kg lifts a total of 550 kg. Using the DOTS calculator, his score is approximately 402.15.
Example 2: The Heavyweight Powerhouse
A male lifter weighing 110 kg lifts a total of 700 kg. Despite lifting 150kg more than the first lifter, his DOTS score is approximately 401.85. In a competition, the 75kg lifter would win the "Best Lifter" award by a narrow margin.
How to Use Step-by-Step
- Select Gender: Choose Male or Female as the coefficients are derived from different physiological datasets.
- Set Units: Toggle between Kilograms and Pounds. The formula uses KG internally, so our tool converts LB automatically.
- Enter Body Weight: Input your weight at the time of the lift (weigh-in weight).
- Enter Total: Sum your best successful Squat, Bench Press, and Deadlift.
- Analyze Result: Your DOTS score will appear instantly. A score above 350 is good, 450 is national level, and 500+ is world-class.
