Wilks Calculator

Using the Wilks formula, our Wilks calculator will enable you to determine your strength. This calculator relies on three key points of information, your sex, body weight and total lifted weight, to determine your Wilks score.

It couldn't be easier to calculate your strength. First, choose whether you would like to enter your measurements in imperial or metric. Next, choose your sex, then, input you weight and your total lifted weight. (Your total lifted weight is the total of your deadlift, bench and squat lifted weight.) Finally, select "Calculate" to see your score.

Explaining Wilks

The term 'Wilks' is primarily found in powerlifting. It is the abbreviation of the Wilks coefficient or the Wilks formula, which was created by the CEO of Powerlifting Australia Robert Wilks.

To determine their Wilks score, a lifter needs to know just two factors, their weight and their total lifted weight. The score that a lifter is given reflects their relative strength and is a valuable tool for comparing the strength of different lifters.

For instance, consider a male lifter weighing 220lb with a total lifted weight of 1500lb (lifter A) and a male lifter weighing 150lb with a total lifted weight of 1300lb (lifter B). While lifter A may have greater absolute strength than lifter B, lifter B's relative strength, with a Wilks score of 451.8 versus lifter A's score of 414.4, is higher.

The Wilks Formula

Our Wilks calculator applies the Wilks formula, developed by the CEO of Powerlifting Australia Robert Wilks, to determine your Wilks score. The Wilks formula is as follows:

Wilks Formula for Men: Wilks Score = TWL * 500 / (a + b * BWT2 + c * BWT3 + d * BWT4 + e * BWT5 + f * BWT6)
Where: TWL is the total weight lifted [kg], BWT is the body weight of the lifter [kg],
a = -216.0475144, b = 16.2606339, c = -0.002388645, d = -0.00113732, e = 7.01863E-06, f = -1.291E-08.
Wilks Formula for Women: Wilks Score = TWL * 500 / (a + b * BWT2 + c * BWT3 + d * BWT4 + e * BWT5 + f * BWT6)
Where: TWL is the total weight lifted [kg], BWT is the body weight of the lifter [kg],
a = 594.31747775582, b = -27.23842536447, c = 0.82112226871, d = -0.00930733913, e = 4.731582E-05, f = -9.054E-08.
