DOTS Calculator
DOTS is the IPF's preferred coefficient for comparing powerlifting totals across bodyweights - more accurate than Wilks for lighter and heavier lifters.

About the DOTS Score
DOTS - Dynamic Objective Total Score - is the International Powerlifting Federation's current official coefficient for comparing powerlifting totals across bodyweight classes. It was introduced in 2019 as a replacement for the Wilks score, which research had shown to systematically over-reward lighter lifters and under-reward heavier ones at the extremes of the bodyweight spectrum.
The formula uses a fourth-degree polynomial (one degree lower than Wilks), calibrated to produce a more uniform score distribution across the full range of competitive bodyweights - from the 47 kg female class to the Open 120+ kg male class. The result is that a DOTS score of, say, 350 points means approximately the same level of relative performance regardless of whether you weigh 60 kg or 120 kg.
For most recreational lifters, the difference between Wilks and DOTS is small - the formulas diverge most at the extremes. If you compete in the IPF or an affiliated national federation, DOTS is the number that will appear on your official results. For historical comparisons or comparisons with lifters in non-IPF federations, you may still need to reference Wilks.
Frequently Asked Questions
What is a DOTS score?
DOTS (Dynamic Objective Total Score) is a bodyweight-adjusted coefficient used in powerlifting to compare athletes across weight classes. It was adopted by the International Powerlifting Federation (IPF) in 2019 to replace Wilks.
How is DOTS calculated?
DOTS divides 500 by a fourth-degree polynomial of your bodyweight (in kg), then multiplies by your total in kg. The result is a single number where higher is better, with separate coefficients for males and females.
What is a good DOTS score?
Like Wilks, approximate benchmarks are: below 200 recreational, 200–300 intermediate, 300–400 advanced, 400–500 elite, 500+ world class. These reflect raw totals at a competitive level.
Why did the IPF switch from Wilks to DOTS?
Research showed Wilks systematically over-rewarded lighter lifters and under-rewarded heavier ones. DOTS was designed to produce a more uniform distribution of scores across all bodyweights, making inter-class comparisons fairer.
Does DOTS work for single lifts?
DOTS was designed for the full powerlifting total (squat + bench + deadlift). You can technically apply it to a single lift's total, but it will not reflect the coefficient's intent. Use it for the full three-lift total for meaningful results.
How does DOTS compare to IPF GL Points?
Both are modern IPF-sanctioned scoring methods. DOTS compares you to other lifters using a statistical model, while IPF GL points scale your total relative to the world record at your bodyweight - 100 GL points is roughly world-record level.
