What is the difference between DOTS and Wilks?

DOTS is a newer 4th-degree polynomial formula designed to reduce the bodyweight bias found in the classic 1994 Wilks 5th-degree polynomial.

Why does the equipment selection change my score?

The IPF GL and Goodlift formulas use specific coefficients for raw versus equipped lifting to account for the supportive gear used.

Does this calculator require an internet connection?

No, it performs all polynomial calculations locally and deterministically without calling external federation APIs.

What is a world-class score in IPF GL Points?

In the IPF GL system, a score of approximately 100 points is generally considered a world-class performance.

Can I enter my weights in pounds?

Yes, you can input weights in pounds, and the calculator will convert them to kilograms internally for the formulas.

Powerlifting Coefficient (DOTS / IPF GL) Calculator

Compare a powerlifting total across four strength coefficient systems side by side: DOTS, Wilks (1994), IPF GL Points and Goodlift. Enter sex, body weight and three-lift total (squat + bench + deadlift) in kg or lb, and see each formula's points, coefficient, relative-strength tier and a progress bar showing how close the total is to each system's elite threshold. Complements the existing Wilks calculator by adding DOTS and IPF GL rather than replacing it.

What this tool helps you do

A strength-coefficient calculator for powerlifters, coaches and meet directors:

Enter the lifter's sex, body weight and three-lift total (squat + bench press + deadlift). Weights can be in kilograms or pounds and are converted internally.
The tool computes four systems in parallel: DOTS (4th-degree polynomial, 500-normalised), Wilks (the classic 1994 5th-degree polynomial), IPF GL Points (official IPF formula since 2019, ~100 = world-class) and Goodlift.
A progress bar shows how close the total is to each system's elite threshold, since DOTS/Wilks and GL/Goodlift use very different point scales.
Each formula shows its points, coefficient (where one applies) and a relative-strength tier, plus a one-line explanation of how that system works.
Mark Raw vs Equipped: IPF GL and Goodlift use equipment-specific coefficients, so the equipment choice changes those two scores.

Offline and deterministic: pure polynomial computation, no federation API or live data.
