The Dots Calculator is designed to provide a fair comparison of powerlifting performances across different body weights. By calculating a Dots score, lifters can objectively compare their total lifts regardless of their weight class, making competitions more equitable.
The Formula of USAPL Dots Calculator
The formula used by the USAPL Dots Calculator is:
Dots = (500 / (a + b * BW + c * BW^2 + d * BW^3 + e * BW^4)) * Total
- Dots: The Dots score.
- BW: Body weight of the lifter in kilograms.
- Total: Sum of the best squat, bench press, and deadlift in kilograms.
- Coefficients differ based on gender:
- For men: a = 0.00001291, b = -0.0007393, c = 0.0023886, d = -0.0012757, e = 0.000009579
- For women: a = 0.00000914, b = -0.0004924, c = 0.0019436, d = -0.0010736, e = 0.000008723
Understanding these coefficients and their impact on the score is crucial for using the calculator effectively.

Example of USAPL Dots Calculator
Let's consider a male lifter weighing 90 kilograms with a total lift of 700 kilograms. Using the formula, his Dots score would be calculated as follows:
Dots = (500 / (0.00001291 + -0.0007393 * 90 + 0.0023886 * 90^2 + -0.0012757 * 90^3 + 0.000009579 * 90^4)) * 700
This example helps illustrate the calculation process and the impact of each variable.
