DOTS Score Calculator
Use this DOTS score calculator to convert a powerlifting total and bodyweight into a bodyweight-adjusted DOTS score. Enter a total directly or enter squat, bench press, and deadlift separately. Pound inputs are converted to kilograms before the published male or female DOTS polynomial is applied.
DOTS uses score = total × 500 ÷ denominator, where the denominator is a sex-specific fourth-degree polynomial of bodyweight in kilograms: A·bw⁴ + B·bw³ + C·bw² + D·bw + E. With the coefficients used here, a 750 kg total at 93 kg bodyweight under the male formula is approximately 477.2 DOTS.
score = total × 500 ÷ (A·bw⁴ + B·bw³ + C·bw² + D·bw + E)Interactive step-by-step proof

DOTS, Wilks and IPF GL Are Different Relative-Scoring Methods
The International Powerlifting Federation published a 2020 evaluation comparing GL, the earlier IPF formula, Wilks, Wilks-2 and DOTS across multiple competition categories.
The IPF separately states that IPF GL Points replaced its earlier IPF formula and became the points system used at IPF-sanctioned events from May 1, 2020. DOTS therefore should not be substituted for IPF GL when an official IPF result requires GL points.
This calculator is specifically for users who need a DOTS calculation. For competition results, first confirm which scoring method the relevant federation or meet specifies.
Why Powerlifting Uses Relative-Scoring Formulas
Relative-scoring formulas transform a powerlifting total using bodyweight so performances from lifters of different bodyweights can be compared under a specified scoring model. DOTS uses separate fourth-degree polynomial coefficient sets for male and female lifters.
The result is a DOTS score, not a universal measure of athletic ability and not an official placing unless the relevant competition uses DOTS. Different scoring systems can produce different relative scores because their mathematical models differ.
For official standings, use the scoring method named by the federation or meet organizer. The IPF currently documents IPF GL Points for its sanctioned events rather than DOTS.
How to Calculate Your DOTS Score, Step by Step
The calculator converts inputs to kilograms, evaluates the selected DOTS polynomial, and applies the score formula.
Step 1 — collect your total
Either type your total directly, or switch to squat/bench/deadlift mode so the calculator adds the three competition lifts together for you.
Step 2 — build the bodyweight coefficient
Your bodyweight is run through a fourth-degree polynomial — A·bw⁴ + B·bw³ + C·bw² + D·bw + E — using coefficients specific to your sex.
Step 3 — apply the formula
Your total is multiplied by 500 and divided by that bodyweight coefficient, producing your DOTS score.
Step 4 — use the right scoring system
Use the resulting DOTS value where DOTS is the intended comparison method. Official federation scoring may use a different formula.
DOTS Score Worked Examples
These are realistic illustrative inputs calculated with the same coefficients used by the tool. They are not real athlete profiles or official meet results.
Male formula: 93 kg bodyweight
750 × 500 ÷ 785.85 ≈ 477.2.
Female formula: individual lifts
470 × 500 ÷ 580.82 ≈ 404.6.
Same total, different bodyweights
The same raw total produces different DOTS values because bodyweight is part of the formula.
DOTS Score Calculator: Mistakes to Avoid
Selecting the wrong sex
The men’s and women’s DOTS formulas use entirely different polynomial coefficients. Picking the wrong option won’t just shift the score slightly — it can produce a number that’s off by a meaningful margin in either direction.
Mixing units mid-entry
Switching between kg and lb after already typing values can leave stale numbers in the wrong unit. This calculator clears the fields on a unit switch specifically to avoid that, so re-enter your values after toggling units.
Entering an event-day bodyweight that doesn’t match the total
For a competition-style comparison, use the bodyweight associated with the performance being scored. Mixing a current bodyweight with an unrelated historical total changes the calculation.
Assuming every federation scores meets with DOTS
DOTS is not universal. The IPF documents IPF GL Points for its sanctioned events, so confirm the scoring system used by the specific federation or meet.
DOTS, Wilks and IPF GL
These systems all adjust performances for bodyweight, but they use different mathematical models and are not interchangeable.
DOTS
This calculator applies the published DOTS polynomial coefficients. Use it when DOTS is the requested scoring method.
Wilks / Wilks-2
Wilks and Wilks-2 are separate relative-scoring formulas with their own coefficients. A Wilks result should not be labeled as DOTS.
IPF GL Points
The IPF states that GL Points replaced its earlier IPF formula and are used at IPF-sanctioned events.
Published comparison
The IPF’s 2020 model evaluation includes statistical comparisons of GL, the earlier IPF formula, Wilks, Wilks-2 and DOTS across competition categories.
