How to Calculate Your IPF Lifting Score

As powerlifting has grown in popularity, so has the need for a standardized scoring system to compare performances across different weight categories and age groups. The IPF (International Powerlifting Federation) developed a standardized IPF GL (GoodLift) score to address this.

The IPF GL Score is a points-based system developed to compare individual powerlifting performances across different bodyweights, ages, and genders. The IPF GL score evens the playing field by adjusting for the body weight of the lifter to determine a score relative to other lifters.

It is used to help evaluate performance and determine the best overall lifter in competitions by factoring in these variables.

To calculate the IPF GL Score, you’ll need to know the lifter’s body weight, the total amount they lifted, and what event they competed in. Then, you can use the formula published by the IPF to calculate the IPF GL score:^[1]

Where:
x = lifter’s body weight
w = total weight lifted
e = natural logarithm
A, B, and C = parameters supplied by the IPF^[1]

The IPF provides separate parameters for use in measuring strength in all events, bench press, squat, or deadlift.

How to Calculate Your DOTS Lifting Score

The DOTS score (Dynamic Objective Total Score) is also a newer and more sophisticated formula that aims to solve the same problem in evaluating the lifter’s performance as the IPF GL score. The DOTS score is also a measurement of the amount of weight lifted relative to the lifter’s body weight.

The DOTS score is commonly used to evaluate performance in powerlifting competitions. You can calculate your DOTS score using a formula:^[2]

Where:
x = lifter’s body weight
w = total weight lifted
A, B, C, D, and E = parameters in the table below

How to Calculate Your Wilks Lifting Score

The Wilks formula, created by Robert Wilks, the CEO of Powerlifting Australia, is yet another formula used to measure the relative strength of a powerlifter.^[3]

The Wilks coefficient formula was updated in 2020 to refine and improve the measurements when comparing extreme bodyweight classes with those in the middle.

The revised Wilks coefficient formula is:^[2]

Where:
x = lifter’s body weight
w = total weight lifted
A, B, C, D, E, and F = parameters in the table below

The IPF GL, DOTS, and Wilks coefficients and scores all serve to provide a relative benchmark of lifters’ strength and performance compared to their body weight. You might also be interested in our one-rep max calculator to calculate your lifting strength.
