DOTS Calculator: DOTS, Wilks and IPF Points
Calculate DOTS, Wilks & IPF GL
Three powerlifting formulas in one calculator.
DOTS points relate your powerlifting total to body weight: total × 500 divided by a polynomial of body weight. The calculator also shows the original Wilks score and IPF GL points.
What is a DOTS score?
In powerlifting, lifters of different weight classes are compared with scoring formulas. The total of squat, bench press and deadlift is divided by a curve that depends on body weight. For DOTS this is a fourth-degree polynomial: DOTS = total × 500 ÷ (A·BW⁴ + B·BW³ + C·BW² + D·BW + E). The coefficients A to E differ for men and women; the calculator uses the values from the report by Kopayev et al. (2020) published by the International Powerlifting Federation.
DOTS, Wilks and IPF GL compared
| Formula | Structure | Note |
|---|---|---|
| DOTS | Total × 500 ÷ 4th-degree polynomial | Coefficients per Kopayev et al. (2020) |
| Wilks (original) | Total × 500 ÷ 5th-degree polynomial | Coefficients per Kopayev et al. (2020) |
| IPF GL | Total × 100 ÷ (A − B · e−C · BW) | Official IPF formula since 2020 |
On behalf of the IPF, Kopayev et al. (2020) compared several formulas – including Wilks, Wilks-2, DOTS and IPF GL – using competition results. The IPF itself has scored with GL points since 2020; according to the IPF, 100 points equal the average of elite athletes at the same body weight.
Which score should I use?
It depends on the competition: each federation decides which formula it uses. For tracking your own progress, it matters more to always use the same formula. If you only train the bench press, the bench press calculator shows IPF points for the bench.
