Calculate a three-lift DOTS score
DOTS multiplies a powerlifting total by a bodyweight-based coefficient. It gives you one number for comparing totals across bodyweights. This tool calculates the standard score, and can also show a masters age-adjusted score using USA Powerlifting’s published coefficients.
- Choose kilograms or pounds. Use the same unit for bodyweight and every lift.
- Select the published men’s or women’s formula for the category you are comparing, then enter bodyweight.
- Enter a three-lift total, or choose Three lifts and enter squat, bench press, and deadlift separately. Include the bar in each lift.
- Optional: choose Masters 40+ and enter your age to see an age-adjusted score beside the standard one.
Both entry modes require positive weights. The individual-lift mode adds one weight per lift; it does not add all of your attempts or multiply by repetitions. For a meet comparison, use the recorded bodyweight and accepted total from that meet. A set of gym bests from different days is a separate comparison, so label it that way in your log.
DOTS formula and coefficients
The original specification by Tim Konertz publishes two fourth-degree polynomial curves. Let W be bodyweight in kilograms after applying the boundary rule below, and T be the three-lift total in kilograms.
Coefficient = 500 ÷ (aW⁴ + bW³ + cW² + dW + e)
DOTS score = T × coefficient
| Term | Men | Women |
|---|---|---|
| a · W⁴ | -0.000001093 | -0.0000010706 |
| b · W³ | 0.0007391293 | 0.0005158568 |
| c · W² | -0.1918759221 | -0.1126655495 |
| d · W | 24.0900756 | 13.6175032 |
| e | -307.75076 | -57.96288 |
The bodyweight domains are 40–210 kg for men and 40–150 kg for women. Outside a domain, DOTS uses the coefficient at its nearest boundary. For example, the women’s formula uses its 150 kg coefficient for an entered bodyweight of 160 kg. This calculator shows a notice whenever that rule applies; the lifting total stays unchanged.
Pound entries are converted using 1 lb = 0.45359237 kg. Calculations keep full precision, and the final score is displayed to two decimal places. Switching units preserves the entered quantities; editing a converted field replaces that entry with the new value shown in your selected unit.
Worked examples in kilograms
With the men’s formula, an 83 kg bodyweight and lifts of 180 kg squat, 120 kg bench press, and 200 kg deadlift make a 500 kg total. The coefficient is approximately 0.675087376.
180 + 120 + 200 = 500 kg
500 × 0.675087376 ≈ 337.54 DOTS
With the women’s formula, a 60 kg bodyweight and 400 kg total use a coefficient of approximately 1.108545625, giving 443.42 DOTS. These are arithmetic examples, not targets or strength classifications.
DOTS score chart: the total each score needs
The same score needs a different total at each bodyweight. These tables show the three-lift total, in kilograms, that produces a given DOTS score. They are the formula rearranged (total = score ÷ coefficient) and rounded to the nearest kilogram. They are not strength standards or percentiles.
| Bodyweight | 300 DOTS | 350 DOTS | 400 DOTS | 450 DOTS | 500 DOTS |
|---|---|---|---|---|---|
| 60 kg | 355 kg | 415 kg | 474 kg | 533 kg | 592 kg |
| 75 kg | 418 kg | 488 kg | 558 kg | 627 kg | 697 kg |
| 90 kg | 464 kg | 541 kg | 619 kg | 696 kg | 773 kg |
| 105 kg | 497 kg | 580 kg | 663 kg | 746 kg | 829 kg |
| 120 kg | 522 kg | 609 kg | 696 kg | 784 kg | 871 kg |
| Bodyweight | 300 DOTS | 350 DOTS | 400 DOTS | 450 DOTS | 500 DOTS |
|---|---|---|---|---|---|
| 50 kg | 239 kg | 279 kg | 319 kg | 359 kg | 399 kg |
| 60 kg | 271 kg | 316 kg | 361 kg | 406 kg | 451 kg |
| 70 kg | 297 kg | 346 kg | 396 kg | 445 kg | 494 kg |
| 80 kg | 318 kg | 371 kg | 425 kg | 478 kg | 531 kg |
| 90 kg | 337 kg | 393 kg | 449 kg | 505 kg | 561 kg |
Read across a row to see how the score scales with the total, or down a column to see how much more a heavier lifter must total for the same score. For any other bodyweight, or for pounds, use the calculator above.
Age-adjusted DOTS for masters lifters
The DOTS formula itself has no age term. USA Powerlifting (USAPL) publishes a separate table of masters age coefficients for each year from age 40 to 95, and defines a master lifter’s age-adjusted DOTS as the DOTS score multiplied by that coefficient. Choose Masters 40+ in the calculator to apply it.
Age-adjusted DOTS = DOTS score × age coefficient
Age 50: 337.54 × 1.066 ≈ 359.82
| Age | Coefficient | 337.54 DOTS becomes |
|---|---|---|
| 40 | 1.000 | 337.54 |
| 45 | 1.026 | 346.32 |
| 50 | 1.066 | 359.82 |
| 55 | 1.120 | 378.05 |
| 60 | 1.194 | 403.03 |
| 65 | 1.290 | 435.43 |
| 70 | 1.411 | 476.27 |
| 75 | 1.562 | 527.24 |
| 80 | 1.745 | 589.01 |
The coefficient is 1.000 at age 40, so the adjustment starts at 41. The published table has no values below 40 or above 95, and this calculator does not extend it. Other federations may rank masters or junior lifters with different coefficients; use the ones your event specifies.
What does a DOTS score mean?
A higher DOTS score represents a higher total after the formula’s bodyweight adjustment. At a fixed bodyweight and formula category, a 5% larger total produces a 5% larger score. If bodyweight changes too, the coefficient changes.
The score does not tell you how many people you outperform, what load to attempt next, or how much muscle you have gained. For your own history, record the date, bodyweight, lifts, equipment, and whether the result came from a meet or training. Keep those conditions visible when comparing scores.
The calculator does not adjust for equipment or judging standards, and the only age adjustment it offers is the optional USA Powerlifting masters coefficient. For a competition result or qualification, check that event’s current rules and official results.
Common questions
What is a good DOTS score?
It depends on the comparison. Start with results for the event, category, and equipment you care about, or your own comparable previous totals. The score chart shows the total each score needs at several bodyweights. This tool does not label scores as beginner, elite, or a percentile: those claims would need a defined population and supporting data.
Does DOTS account for age?
Not by itself. The formula uses only bodyweight and the lifted total. USA Powerlifting publishes masters age coefficients for ages 40 to 95 that multiply a DOTS score; the calculator’s Masters 40+ option applies them. It has no adjustment for lifters under 40.
Is DOTS the same as Wilks or IPF GL?
No. They are different scoring formulas, so their points are not interchangeable. This calculator implements DOTS only. Do not relabel a DOTS result as a Wilks or IPF GL score.
Can I enter a bench-only result?
This page is designed around a squat, bench press, and deadlift total. Entering only a bench result in the total field would produce arithmetic, but it would not be a three-lift comparison. Use the rules and scoring method specified for your single-lift event.
Why are there two formula categories?
The published DOTS specification provides men’s and women’s coefficient sets. These controls select a curve for the calculation. They do not determine competition eligibility or supply a separate curve for every federation category; consult your event’s rules for that comparison.
Can I use estimated one-rep maxes?
You can explore a hypothetical total, but label it as estimated. Adding estimates introduces their uncertainty into the DOTS result. The RPE calculator explains its estimation method; an estimated total is not a completed meet total.
Are my bodyweight and lifts saved?
These entries and results stay in this page’s browser session. They are not submitted or stored, and reloading resets the example. Use the free workout log to keep your own record.
