DOTS Score Calculator
Calculate the DOTS score for powerlifting to compare relative strength across different body weights and sexes.
Calculator
Formula
Total is the sum of best squat, bench press, and deadlift in kg. w is the lifter's bodyweight in kg. Coefficients a, b, c, d, and e differ by sex. The formula produces a score where higher values indicate greater relative strength.
Source: Tim Dallenbach, DOTS formula (2019). Used as the official IPF ranking formula starting in 2020.
How it works
The DOTS formula divides your powerlifting total (squat + bench press + deadlift) by a polynomial function of your bodyweight, then multiplies by 500 to produce a convenient score. The polynomial denominator was derived by Tim Dallenbach through regression analysis of elite competition data to produce consistent, fair comparisons across the full spectrum of competitive bodyweights.
Separate coefficients are used for male and female lifters because strength-to-bodyweight relationships differ physiologically between sexes. A score near 300 is typically considered competitive at a regional level, while elite international lifters often exceed 400–500 DOTS points. The formula is specifically designed so that the score is stable and does not disproportionately reward very light or very heavy lifters.
DOTS replaced the older Wilks coefficient as the IPF's official ranking metric in 2020 due to concerns that Wilks undervalued superheavy lifters. DOTS is now widely used in IPF-affiliated federations worldwide for determining best lifter awards and overall rankings.
Worked example
Suppose a male lifter weighing 82.5 kg posts a squat of 200 kg, a bench press of 130 kg, and a deadlift of 240 kg.
Step 1 — Compute the total: 200 + 130 + 240 = 570 kg
Step 2 — Evaluate the polynomial denominator at w = 82.5 using the male coefficients: a = −1.0706×10⁻⁸, b = 1.2497×10⁻⁵, c = −5.5444×10⁻³, d = 1.0659, e = −96.760. Substituting gives approximately denom ≈ 513.06.
Step 3 — Calculate DOTS: 570 × (500 / 513.06) ≈ 555.6. This is an elite-level score, reflecting a very strong performance relative to bodyweight.
Limitations & notes
DOTS is calibrated on competition data from equipped and raw powerlifting; applying it to partial lifts or non-competition attempts may produce misleading comparisons. The formula assumes bodyweight within the range of approximately 40–200 kg — extreme values outside this range may yield less reliable results. DOTS does not account for age (Masters or Junior categories), equipment type (raw vs. single-ply vs. multi-ply), or drug-testing status, so cross-context comparisons should be made cautiously. Finally, DOTS compares the full three-lift total; it is not designed for single-lift (bench-only or deadlift-only) comparisons, though it is sometimes applied this way informally.
Frequently asked questions
What is a good DOTS score?
For raw powerlifting, a DOTS score below 200 is beginner level, 250–300 is intermediate, 300–380 is advanced/competitive at the national level, and scores above 400 indicate elite performance. The very best lifters in the world can exceed 500 DOTS points.
How does DOTS differ from Wilks?
Both DOTS and Wilks adjust a total by bodyweight using polynomial coefficients, but DOTS was specifically calibrated to produce more equitable scores for superheavyweight lifters, who were historically undervalued by the Wilks formula. The IPF replaced Wilks with DOTS in 2020 for this reason.
Can I use DOTS to compare raw and equipped lifters?
DOTS can mathematically be applied to both raw and equipped totals, but the resulting scores are not directly comparable because equipped gear (suits, shirts) allows substantially heavier totals. You should only compare DOTS scores within the same equipment category.
Is DOTS used in all powerlifting federations?
DOTS is the official metric of the IPF and all IPF-affiliated national federations. Other federations such as the USPA, RPS, and WRPF may use different formulas (Wilks, Glossbrenner, or their own), so DOTS scores may not be officially recognized outside IPF-affiliated competitions.
Does bodyweight need to be the official weigh-in weight?
For competition ranking purposes, yes — the bodyweight used should be the official weigh-in weight recorded at the meet. For personal tracking or informal comparisons, you can use your current bodyweight, but be aware that even small differences can meaningfully affect the DOTS score, especially at lighter body weights where the polynomial curve is steeper.
Why does the DOTS formula use a polynomial rather than a simple ratio?
A simple strength-to-bodyweight ratio (total / bodyweight) overvalues lighter lifters because strength does not scale linearly with mass — it scales closer to the 2/3 power of body mass. A fitted polynomial more accurately captures the non-linear relationship between bodyweight and maximum strength potential observed in elite competition data.
