Wilks score calculator.

What Wilks actually measures.

A raw powerlifting total tells you how much you lifted. Wilks tells you how much you lifted relative to your bodyweight, adjusted by a polynomial curve that accounts for the non-linear relationship between body size and absolute strength. Two lifters with the same Wilks score are considered roughly equivalent in strength, regardless of weight class.

The curve was calibrated on competition data. Heavier lifters lift more in absolute terms, but the curve scales their totals down to make the comparison fair across classes. The problem is that the original curve was imperfect at the extremes, which is what led to Wilks 2 (2020) and DOTS.

How to read your number.

A 300 Wilks at 165 lb and a 300 Wilks at 250 lb represent the same level of bodyweight-adjusted strength output, at least according to the Wilks curve. If your score holds steady as your bodyweight goes up, your relative strength is not improving. If your score rises, you're gaining strength faster than bodyweight.

Week-to-week fluctuations of 3-5 points are normal noise from bodyweight variance and daily variation in performance. A shift of 15-30 points over a training block is meaningful. A 30-point gain in a year is a strong result.

Wilks vs. Wilks 2 vs. DOTS.

The original Wilks formula has been the cultural reference for powerlifting strength comparison since the 1990s. It's embedded in gym records, online rankings, and decades of competitive history. When someone says "my Wilks," they almost always mean original Wilks.

Wilks 2 (2020) updated the polynomial coefficients using a larger and more current dataset to address bias at the extremes of the bodyweight range. Most lifters in the 70-100 kg range see only minor differences between Wilks and Wilks 2.

DOTS replaced Wilks at IPF events in 2020. If you compete in the IPF or an IPF affiliate, your official score is DOTS. For comparing yourself against historical records or informal rankings online, use original Wilks. Check the DOTS calculator if you need the current IPF formula.

The IPF also runs a Goodlift score called GL points, which the IPF GL points calculator works out from your total.

Why Wilks penalizes the extremes.

The original Wilks polynomial was fit to competition data from the 1990s. At the low end, lifters under 60 kg tend to score higher than their actual relative strength would suggest, because the curve flattens. At the high end, lifters over 120 kg need proportionally larger totals to match the score of a mid-weight lifter. The super-heavyweight at 275 lb in the example above needs nearly a 2,000-lb total to reach the same Wilks as a 220-lb lifter with a 1,400-lb total.

This bias drove the development of both Wilks 2 and DOTS. Neither has fully replaced original Wilks in gym culture, but both produce more equitable outputs at the extremes. If you compete in a class below 60 kg or above 120 kg, you'll want to check your score against both formulas.

When the score doesn't matter.

Wilks is useful for comparing yourself to other lifters and to historical records. For your own training progress, it can serve as a rough benchmark, but it's not the right primary metric. If you added 40 lb to your squat in six months while your bodyweight stayed the same, that's progress regardless of what the Wilks number does.

Track your working maxes over time instead. Wilks gives you context for where you stand relative to other lifters, but a 5-point swing week to week is noise. A consistent upward trend over a full training year means something.
