DOTS Calculator: Powerlifting DOTS Score in kg or lb

How this DOTS calculator works

This DOTS calculator turns a powerlifting total and a bodyweight into points, so lifters of different bodyweights can be compared. Choose male or female, enter your bodyweight and your total, and pick kg or lb. The result is your DOTS score, shown with the substituted formula and the DOTS coefficient for your bodyweight.

Your total is the sum of your best squat, bench press, and deadlift. A single lift can be entered in the total field and is scored the same way. Every result is worked out in kilograms. If you enter pounds, bodyweight and total are both converted first, at 1 lb = 0.45359237 kg.

The DOTS formula

DOTS was created by Tim Konertz in 2019. It divides 500 by a fourth-degree polynomial of bodyweight and multiplies the result by the total:

DOTS = total × 500 ÷ (a + b·x + c·x² + d·x³ + e·x⁴), where x is bodyweight in kg and the total is in kg. The part 500 ÷ (…) is the DOTS coefficient for that bodyweight.

Men: a = −307.75076, b = 24.0900756, c = −0.1918759221, d = 0.0007391293, e = −0.000001093.

Women: a = −57.96288, b = 13.6175032, c = −0.1126655495, d = 0.0005158568, e = −0.0000010706.

These are the coefficients published by the author. The same ten values appear in a 2020 evaluation report prepared for the IPF. The highest power is x⁴, so there are five coefficients for each sex, one fewer than the Wilks formula.

DOTS calculator examples

A man weighing 90 kg with a 600 kg total scores 600 × 500 ÷ 773.2746 = 387.96 DOTS points. His DOTS coefficient is 0.6466.

A woman weighing 60 kg with a 350 kg total scores 387.99 DOTS points. A 100 kg man with a 1,000 kg total scores 615.52, and a 60 kg woman with a 500 kg total scores 554.27.

In pounds, a 200 lb man with a 1,300 lb total converts to 90.72 kg and 589.67 kg, for 379.77 DOTS points. A 132 lb woman with a 700 lb total scores 352.45 DOTS points.

Bodyweight limits

The author defines DOTS from 40 to 210 kg for men and from 40 to 150 kg for women. Outside that range, the coefficient at the nearest limit is used. This calculator follows that rule. It still shows a score and adds a short note, such as “Scored at 210 kg, the top of the DOTS range for men.”

For example, a 250 kg man with a 900 kg total is scored at 210 kg, for 446.06 points. A 35 kg man with a 300 kg total is scored at 40 kg, for 381.33 points. A 160 kg woman with a 500 kg total is scored at 150 kg, for 385.38 points, and a 30 kg woman with a 200 kg total is scored at 40 kg, for 296.96 points. A lifter exactly at a limit is scored at that bodyweight with no note.

These limits come with the formula. They are not the same as the Wilks ranges, so a lifter can be inside the DOTS range and outside a Wilks range.

Kilograms, pounds, and rounding

The coefficients are defined in kilograms, so pounds never go into the formula directly. Bodyweight and total are both converted at exactly 1 lb = 0.45359237 kg, and the conversion is shown with the result. Switching between kg and lb converts the numbers you typed, rounded to two decimals, so 90 kg becomes 198.42 lb. That rounding can move a score by a few hundredths.

Every step keeps full precision. Scores are shown to two decimals, and a score exactly halfway rounds up. The coefficient is shown to four decimals.

DOTS vs Wilks

DOTS and the original Wilks formula have the same shape: total × 500 ÷ a polynomial of bodyweight, with separate coefficients for men and women. DOTS uses a fourth-degree polynomial and its own coefficients, so it is a different scale. The 90 kg man with a 600 kg total scores 387.96 DOTS points. On its own scale, his original Wilks score is 383.04. This page never subtracts one score from the other or ranks one against the other.

To score the same total with the original Wilks and Wilks 2020 formulas, use the Wilks calculator.

Which federations use DOTS

USAPL and USPA use DOTS. The IPF has used IPF GL points since 1 May 2020, and Powerlifting Australia and World Powerlifting use Wilks 2020. This page calculates DOTS only, so check the rulebook of the federation you compete in for the formula it uses.

What a DOTS score does not tell you

A DOTS score compares totals across bodyweights. It does not adjust for age or equipment, and it does not grade the total. It scores lifts you completed. To estimate a one-rep max from a set of several repetitions instead, use the one-rep max calculator.
