What is the Dots coefficient?

The Dots coefficient is a formula created by Tim Koessler in 2019 and adopted by the IPF to replace Wilks. It uses a 4th-degree polynomial of body weight to normalize a powerlifter's total (kg), yielding a single comparable score.

How does Dots differ from Wilks?

Dots produces more equitable scores at the extremes of the body weight spectrum — lighter and heavier lifters are compared more fairly than with the older Wilks formula, which tended to favour lighter lifters.

What Dots score is considered good?

Recreational lifters typically score 200–300. A score of 350–400 is competitive at local meets. National-level competitors often reach 450+, while world-class elite lifters can exceed 500.

Should I enter equipped or raw totals?

The Dots formula itself is the same for both. However, equipped totals will naturally produce higher scores. Only compare Dots scores within the same equipment category (raw vs. equipped).

What body weight range is valid?

The formula is calibrated for 40–210 kg for male lifters and 40–150 kg for female lifters. Inputs outside these ranges produce unreliable results and are flagged as out-of-range.

Is the total in kg or lbs?

The Dots formula requires kilograms. This calculator accepts kg by default. If you train in pounds, divide your total by 2.20462 before entering it.

Summary

Calculate your Dots score to compare powerlifting totals across different body weights and sexes using the IPF-adopted 2019 formula.

How it works

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