Wilks and DOTS are the two most widely used formulas for comparing powerlifting totals across bodyweights. Both convert a raw total into a single score that lets lifters of different sizes compete on equal footing. This page explains how each formula works, when to use each one, and shows your score on both side by side.
Wilks-2 (2020)
Strengths
- Widely recognized outside IPF-affiliated meets
- Robert Wilks updated it in 2020 to address known flaws
- Useful when comparing to historical Wilks scores
- Some raw federations still use it as their primary metric
Limitations
- Not the IPF standard - you cannot use it for IPF rankings
- Less weight-class-neutral than DOTS in some analyses
- Two different versions (2004 and 2020) cause confusion
Best When
Use Wilks-2 when competing in a federation that still uses it, or when you want to compare your score against historical records predating 2019. Also useful for peer comparison when your training partners track Wilks.
DOTS
Strengths
- Official IPF scoring system since 2019
- Used in IPF World Championships and all affiliates
- Developed specifically to address Wilks flaws with modern data
- Simpler formula structure (4th vs 5th degree polynomial)
Limitations
- Less familiar outside IPF circles
- Scores not directly comparable to legacy Wilks totals
- Still contains some bodyweight-class bias at extremes
Best When
Use DOTS for any IPF-affiliated competition. It is the official standard for IPF Worlds, IPF Opens, and all national federations that affiliate with the IPF. If you plan to compete internationally, DOTS is the number that matters.

Verdict
For competition use, DOTS wins by default if you compete IPF. For general training comparison, both formulas produce very similar results - within a few points of each other for most lifters. Track whichever your federation uses, and use this calculator to compare both whenever you want a complete picture.
How the Wilks-2 Formula Works
The Wilks-2 formula (2020 revision) calculates a coefficient based on your bodyweight using a 5th-degree polynomial equation. This coefficient is then multiplied by your total to produce a bodyweight-normalized score. The formula uses separate male and female coefficients to account for natural strength differences between sexes.
The original 2004 Wilks formula was criticized for favoring certain bodyweight classes, particularly lighter lifters, due to the limited competition data available at the time. Robert Wilks revised it in 2020 using a much larger dataset of modern competition results, reducing this bias significantly.
A score of 300 DOTS or Wilks is generally considered the recreational-to-competitive threshold. Elite raw lifters typically score 400-500+, while the absolute best in the world approach 600.
How the DOTS Formula Works
DOTS (Dynamic Objective Team Scoring) was introduced by the IPF in 2019 to replace the original Wilks formula as the primary scoring system for international competition. It uses a 4th-degree polynomial rather than 5th-degree, making it slightly simpler mathematically while achieving better fairness across bodyweight classes.
The DOTS development team analyzed IPF competition data from recent years to build coefficients that reflect the actual distribution of competitive strength across bodyweight categories. Unlike Wilks, DOTS was purpose-built to work well for both raw and equipped lifting with the same formula structure.
Since 2019, all IPF World Championships, IPF Opens, and affiliated national meets use DOTS as the primary scoring metric. Most national record databases have been converted to DOTS scores.
Wilks vs DOTS: Score Differences in Practice
For most lifters in the typical competitive range (200-450 points), Wilks-2 and DOTS scores are very close - often within 5-15 points of each other. The differences become more pronounced at extreme bodyweights (below 59kg or above 120kg) where the coefficient curves diverge more.
In general, DOTS tends to score very light lifters slightly higher and very heavy lifters slightly lower compared to Wilks-2. The practical impact for most lifters is small enough that both formulas give essentially the same competitive picture.
