DOTS Calculator (IPF points)
Enter your bodyweight and your total (or a single lift), then choose men's or women's coefficients. Nothing is preselected, and the score appears once you choose. You get a DOTS score, so you can compare lifters of different bodyweights. It's free, needs no account, and your inputs stay on your device. They're never sent to us.
The calculator offers the men's and women's coefficients as the formula's authors published them. Anyone can choose either set: it's a choice of formula, not a question about who you are.
What DOTS is
DOTS is a bodyweight formula written by Tim Konertz for the BVDK, the German member federation of the IPF. The BVDK wanted one score that could rank lifters of all sexes on the same team, which IPF points don't allow. OpenPowerlifting, the open database of meet results, also calculates it. It works in kilograms.
The formula
DOTS = total × 500 ÷ (A·bw⁴ + B·bw³ + C·bw² + D·bw + E)
Here bw is bodyweight in kg and total is in kg.
| Coefficient | Men's coefficients | Women's coefficients |
|---|---|---|
| A | −0.0000010930 | −0.0000010706 |
| B | 0.0007391293 | 0.0005158568 |
| C | −0.1918759221 | −0.1126655495 |
| D | 24.0900756 | 13.6175032 |
| E | −307.75076 | −57.96288 |
| Bodyweight range | 40–210 kg | 40–150 kg |
Bodyweights outside the range count as the nearest limit. For example, 220 kg on the men's coefficients is scored as 210 kg. The calculator uses these coefficients and limits, and shows the score to two decimal places (for example, DOTS 405.05).
Worked examples
Men's coefficients, 83 kg bodyweight, 600 kg total
- Denominator: A·83⁴ + B·83³ + C·83² + D·83 + E = 740.64
- Coefficient: 500 ÷ 740.64 = 0.67509
- DOTS: 600 × 0.67509 = 405.05
Women's coefficients, 63 kg bodyweight, 400 kg total
- Denominator: 464.89
- Coefficient: 500 ÷ 464.89 = 1.07551
- DOTS: 400 × 1.07551 = 430.21
On these numbers, the second total scores higher relative to bodyweight than the first.
DOTS vs IPF GL points
The IPF doesn't use DOTS at its own events. Since 1 May 2020, IPF-sanctioned events have used IPF GL points, and the IPF encourages its member federations to use them at national events too. GL uses a different formula, with separate coefficients for classic and equipped lifting, for full powerlifting and bench-only, and for men and women. So a DOTS score and a GL score for the same lift aren't comparable. If your meet ranks on GL, check the GL number, not DOTS.

A score is for comparing results, not a goal to chase. Train for totals you can lift safely, and check official meet results for the score that counts.
