DOTS Calculator

By Jack Kyle — Jack Kyle writes about strength training and lifting math — calculators, programming and standards — with a focus on honest numbers and practical guidance.

Key findings

• DOTS stands for Dynamic Objective Team Scoring: one points score that lets totals from different weight classes rank together.
• DOTS points = total × DOTS coefficient, where the coefficient is 500 ÷ a fourth-order polynomial of bodyweight, with separate coefficient sets for men and women.
• Check value: an 80 kg male lifter with a 600 kg total scores 413.7 DOTS.
• DOTS is not the IPF’s system — the IPF uses GL points. Never compare a DOTS number with a GL or Wilks number.

Intro

A 500 kg total at 83 kg and a 500 kg total at 120 kg are not the same achievement, but a results sheet that lists raw totals treats them as if they were. DOTS exists to fix that: it converts a total and a bodyweight into one points score, so lifters in different weight classes can be ranked together.

DOTS is a powerlifting scoring system used by some federations as a successor to Wilks. It is distinct from IPF GL points, which are the IPF’s own system. The distinction matters if you follow powerlifting results, because scores published under different systems are not on the same scale. A 400 DOTS score and a 400 IPF GL score are different numbers that happen to share a range.

This calculator gives you the DOTS score for a total you enter. Type in your bodyweight and squat, bench, and deadlift total, pick the male or female set, and the tool returns your DOTS points plus the coefficient it applied. The method follows the published DOTS definition (Dynamic Objective Team Scoring; coefficients by Tim Konertz for the BVDK, 2019), and a human team checked this page for accuracy before it was prepared for publication. For the IPF’s own system, see the IPF GL Calculator.

How it works

The formula

DOTS points = total lifted × DOTS coefficient.

The coefficient = 500 ÷ (a + b·BW + c·BW² + d·BW³ + e·BW⁴), where BW is bodyweight in kg. Coefficients (Konertz, for the BVDK, 2019):

• 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.

The calculator applies the published set for the sex you select and displays the coefficient, so the multiplication can be verified by hand. Check value: an 80 kg male lifter with a 600 kg total scores 413.7 DOTS.

What to enter

• Bodyweight. Your weigh-in bodyweight. Use the weighed figure, not your weight-class label, because the coefficient moves with every kilo.
• Total. Your squat + bench + deadlift total from a single meet or testing day. Do not combine best lifts from different days into one total.
• Sex. Male or female coefficient set, matching the published DOTS tables.

DOTS and Wilks

DOTS is used by some federations as a successor to Wilks. The IPF uses a different system — IPF GL points — so do not assume every federation uses DOTS: check the rulebook for the meet you care about. When you read older results, check which system the score was published under before comparing it with a DOTS score. Never place a Wilks number and a DOTS number on the same ranking.

Honest limits

• The DOTS curve is fitted to group data. It describes an average bodyweight-to-strength relationship, not any individual lifter.
• Scores are sensitive to bodyweight input. A mis-weighed or rounded bodyweight shifts the coefficient and the score.
• DOTS compares totals across bodyweights within powerlifting. It does not compare across sports, across sexes, or across different lift selections.
• The score is only as honest as the total. A total built from gym lifts with loose judging is not the same as a meet total, even if the numbers match.

How to calculate your DOTS score

1. Weigh in. Use your weighed bodyweight in kg, not your weight-class label.
2. Add your three lifts. Squat + bench + deadlift from a single meet or testing day — do not combine best lifts from different days.
3. Select the coefficient set. Male or female, matching the published DOTS tables.
4. Multiply. DOTS points = total × DOTS coefficient, where the coefficient comes from the formula above.
5. Check. Compare your result against the worked example: an 80 kg male lifter with a 600 kg total scores 413.7 DOTS. If your number is far from what that scale suggests, re-check the bodyweight and total you entered.

FAQs

What does DOTS stand for?

DOTS stands for Dynamic Objective Team Scoring. The coefficients were published by Tim Konertz for the German federation (BVDK) in 2019. In practice, lifters just call the number a DOTS score — but the expansion matters when you see a different one elsewhere: any page expanding DOTS differently is describing a different system or an error.

Is DOTS the same as Wilks?

No. DOTS and Wilks use different curves and different scales, so a Wilks score and a DOTS score for the same lifter are not equal and cannot be swapped. DOTS is used by some federations as a successor to Wilks; the IPF uses IPF GL points instead.

Why does the same total score higher at a lower bodyweight?

Because the coefficient rises as bodyweight falls. The system credits lifting a given total at a lighter bodyweight, which is the whole reason for a bodyweight-adjusted score.

Can I use DOTS for a single lift, like bench only?

DOTS was designed for the three-lift powerlifting total. Applying it to a single lift gives a number, but it is not a DOTS score in the sense the system defines. For a single lift, compare raw weight or use a lift-specific reference instead.

Does DOTS work for equipped lifting?

DOTS scores the total you enter. Equipped and raw totals differ by large margins, so only compare DOTS scores within the same lifting style — raw with raw, equipped with equipped — and label the style when you quote a score.
