DOTS calculator and IPF GL points

Bodyweight-adjusted scores let lifters of different sizes compare totals at a meet. Enter your bodyweight and result to see your DOTS score and IPF GL points side by side.

Scores

Enter your bodyweight and total to see both scores.

Compare scores only within the same formula, event (full power or bench only) and equipment category: a bench-only score and a full-power score are different scales, and DOTS and IPF GL numbers can't be compared with each other. Men's and women's results share each formula's scale. Neither score is a percentile. DOTS is shown to two decimals. IPF GL follows the IPF's published procedure (coefficient and points each rounded to six decimals) and is shown to three, as on IPF score sheets; OpenPowerlifting keeps full precision, so its figures can differ by less than 0.001.

What the scores are

A heavier lifter usually lifts more, so a raw total can't decide a best-lifter award across weight classes. Scoring formulas divide your result by a curve fitted to how results rise with bodyweight. They rank performances; they don't say what share of lifters you beat.

DOTS

DOTS was created by Tim Konertz of the German powerlifting federation (BVDK) in 2019 as an updated alternative to the older Wilks formula. Points = result × 500 ÷ a fourth-order polynomial of bodyweight, with separate constants for men and women. Bodyweight is clamped to 40–210 kg for men and 40–150 kg for women. Our implementation follows OpenPowerlifting's reference code and reproduces the DOTS values published in its data.

IPF GL points

The International Powerlifting Federation has used GL (Goodlift) points since 1 May 2020. Points = result × 100 ÷ (A − B × e−C × bodyweight), with different A, B and C for men and women, classic (raw) and equipped lifting, and full power or bench only. They are defined for bodyweights of at least 40 kg (men) and 35 kg (women). Following the IPF's document, the coefficient 100 ÷ (A − B × e−C × bodyweight) is rounded to six decimals, multiplied by the result, and the points are rounded to six decimals; its own example is 0.109039 × 1035 = 112.855365. The official coefficients document is labeled for 1 May 2020 to 31 December 2023, though the IPF site still links it as the current formula; check the IPF for updates before relying on it at a meet.

Worked example

A man weighing 83 kg with a classic (raw) full-power total of 600 kg. The DOTS denominator at 83 kg works out to about 740.64, so DOTS = 600 × 500 ÷ 740.64 ≈ 405.05. His IPF GL coefficient for classic powerlifting is 0.138427, so GL = 0.138427 × 600 = 83.0562 points, shown as 83.056. Enter the same numbers above to check. This tool shows DOTS to two decimals, as OpenPowerlifting publishes, and IPF GL to three, as the IPF's document specifies for general score sheets. OpenPowerlifting calculates GL without the six-decimal rounding, so its figures can differ by less than 0.001 (112.85 rather than 112.86 for the IPF's own example at two decimals).

Limits

  • Scores are only comparable within one formula, and for IPF GL within the same event and equipment category. A DOTS score and a GL score for the same total are different numbers. Both formulas put men's and women's results on one scale, which is why DOTS can be used for mixed comparisons such as team scoring.
  • Meets score official totals made under the rules. A gym total with high squats or touch-and-go benches will score higher than it would on a platform.
  • To see where a lift sits among actual competitors in your class, use the strength standards tool.
