How the Wilks and DOTS Calculator works

This Wilks and DOTS calculator turns a powerlifting total into a score that can be compared across bodyweights. Enter your sex, bodyweight and total, in kilograms or pounds, and it returns your DOTS score, your original Wilks score and IPF GL points for raw or equipped lifting, plus the total you would need at other bodyweights to keep the same DOTS.

Heavier lifters move more weight, but not in direct proportion to their size. Coefficient formulas correct for this so that a 59 kg lifter and a 120 kg lifter can be ranked on one list for best lifter awards. Wilks was the standard for decades, DOTS replaced it in many federations from 2019, and the IPF uses its own GL formula.

How the Wilks and DOTS calculator works

Each formula multiplies your total by a coefficient that falls as bodyweight rises. The Wilks formula is score = total × 500 ÷ (a + b·x + c·x² + d·x³ + e·x⁴ + f·x⁵), where x is bodyweight in kilograms and the six constants differ for men and women. DOTS uses a four-term polynomial with the same 500 numerator. IPF GL is total × 100 ÷ (A − B·e^(−C·x)), with separate constants for raw and equipped lifting.

First example. A 100 kg man with a 700 kg raw total scores 430.86 DOTS, 426.01 Wilks and 88.43 IPF GL points.

Second example. A 63 kg woman with a 400 kg raw total has a DOTS coefficient of 1.0755, so her DOTS is 400 × 1.0755 = 430.21, a strong national-level score.

How many DOTS points is a good total? Around 300 is a solid first meet, 400 is competitive at national level for men, and 500 or more is elite for either sex.

Tips and pitfalls

FAQ

What is the difference between Wilks and DOTS?

Both divide a total by a bodyweight curve, but DOTS was fitted to far more recent meet results and is less biased towards middle weight classes. The original Wilks tended to favour lighter men and heavier women. DOTS is simpler too, with four terms rather than five, and many federations adopted it in 2019 and 2020.

What is a good Wilks score?

For men, a Wilks of 300 marks a decent intermediate lifter, 400 is strong at regional or national level, and above 450 is world class. Women's scores run on the same scale, so the same bands apply. Use them as rough guides only, since standards rise each year.

What are IPF GL points?

The International Powerlifting Federation introduced the Goodlift formula in 2020 to rank lifters at its championships. It gives a score near 100 for a world-class total, with separate constants for raw and equipped lifting and for men and women. A raw score of 90 or more is elite.

Why does my Wilks score not match another calculator?

There are two Wilks formulas: the original from the 1990s and a revised Wilks2020 with different constants and a 600 numerator. This calculator uses the original, which most historical records quote. Small differences can also come from rounding the coefficient or the bodyweight.

Can I use this for a single lift?

Yes. Enter the bench press, squat or deadlift on its own in place of the total, and the calculator scores it with the same coefficient. Single-lift scores are much lower than full-total scores, so compare them only with other single-lift results, such as bench-only meets.
