DOTS Calculator
Quick answer
DOTS multiplies your total by 500 divided by a fourth-degree polynomial of body weight in kilograms. Men and women use different coefficients, published by Tim Konertz for the German federation and used by OpenPowerlifting.
A 90 kg man with a 600 kg total scores about 388. The IPF itself has scored meets with IPF GL points since May 2020. That number is shown beside DOTS so the two are not confused.

Coefficient 0.6466.
IPF GL classic (secondary): 79.77 points.

How does the DOTS calculator work?
Score = total × 500 / (a·bw⁴ + b·bw³ + c·bw² + d·bw + e). Body weight and total are in kilograms. Pounds are converted with 1 lb = 0.45359237 kg before the polynomial runs.
Men: a = −0.0000010930, b = 0.0007391293, c = −0.1918759221, d = 24.0900756, e = −307.75076. Women: a = −0.0000010706, b = 0.0005158568, c = −0.1126655495, d = 13.6175032, e = −57.96288.
What inputs does it need?
Sex, body weight, and a total. The total is your best squat, bench, and deadlift added together, usually from one meet, though the math does not check that.
Very light or very heavy body weights are clamped to the range OpenPowerlifting uses: 40–210 kg for men and 40–150 kg for women. The page says when it clamped.
Worked example with sample numbers
Example only: a man at 90 kg with a 600 kg total. The men's coefficient at 90 kg is about 0.6466. Times 600 is about 388.0 DOTS. The same inputs are about 383 Wilks and about 79.8 IPF GL classic points.
A woman at 63 kg with a 350 kg total lands near 376 DOTS. Comparing her score with the man's is the point of the formula. Comparing the raw totals is not.
Common mistakes
Calling DOTS the current IPF score. It is not. The IPF moved to IPF GL points. DOTS remains the default sort on OpenPowerlifting and in a lot of gym talk.
Mixing equipped and classic totals, or a gym total with a meet total, and then treating a 5-point gap as meaningful. The polynomial is exact. The lifts you fed it may not be.
FAQ
Who published DOTS?
Tim Konertz, for the German powerlifting federation (BVDK). OpenPowerlifting uses the same coefficients.
Does the IPF use DOTS?
No. IPF meets have used IPF GL points since 1 May 2020. This page shows classic powerlifting GL as a second number.
Why clamp body weight?
The polynomial is not meant for extremes. OpenPowerlifting treats outliers as if they weighed the nearest limit. This calculator does the same and tells you.
Do I include warm-ups in the total?
No. The total is the three best competition-style singles, or the three gym singles you are willing to stand behind. Not a 5-rep set.
Is a higher DOTS always a better lifter?
It is a better bodyweight-adjusted total under this formula. It says nothing about technique, weight-class strategy, or a single lift.
