Dots Coefficient Calculator

Summary

The Dots coefficient is a formula introduced in 2019 by Tim Koessler and adopted by the International Powerlifting Federation (IPF) to replace the Wilks score. It normalizes a lifter's total (kg) against body weight and sex, producing a single score that lets you compare performance across all weight classes on a level playing field. A Dots score above 400 is considered competitive; elite lifters often exceed 500.

How it works

1. Select your sex (male or female) — each uses a different set of polynomial coefficients.
2. Enter your body weight in kilograms (valid range: 40–210 kg for male, 40–150 kg for female).
3. Enter your powerlifting total in kilograms (sum of best squat + bench press + deadlift).
4. The calculator applies the Dots polynomial formula: Total × (500 / polynomial denominator).
5. Your Dots score appears instantly alongside a performance tier label.

Use cases

• Compare your powerlifting total against lifters in different weight classes.
• Track progress over time as your body weight changes.
• Evaluate meet performance using the same metric as IPF-sanctioned competitions.
• Determine an all-time total goal based on a target Dots score.
• Coach athletes and rank them fairly regardless of weight class.
• Plan a weight cut or bulk and see the expected impact on your Dots score.
