The formula
How to calculate dOTS calculator
DOTS (Dynamic Objective Team Scoring) is a bodyweight-normalization formula introduced in 2019 to replace the older Wilks formula in competitive powerlifting. Like Wilks, it turns a squat, bench press and deadlift total into a single coefficient-adjusted score so lifters of different bodyweights can be ranked on one scale — but it was fitted to a larger, more modern dataset and behaves more consistently across the full bodyweight range.
The DOTS coefficient comes from a 4th-degree polynomial fitted to bodyweight, with separate sets of five constants for men and women. Dividing 500 by that polynomial produces the multiplier applied to the total. The equipment field above (raw or equipped) is purely informational here — it labels the lift for your own reference and does not feed into the DOTS formula, since DOTS itself makes no distinction between raw and equipped lifting; the polynomial coefficients are identical either way.
Here is what each field means:
- Gender
- Bodyweight (kg)
- Squat (kg)
- Bench press (kg)
- Deadlift (kg)
- Equipment

Where a figure is not immediately to hand — a precise interest rate, an exact balance — a reasonable estimate is a perfectly good starting point. Because every result updates instantly, refining a rough guess into the real figure once you have it takes a moment, and nothing about the calculation depends on getting it exactly right on the first attempt.
Why dOTS calculator matters
A calculation like this usually gets used at a decision point rather than out of curiosity — comparing two real options, checking a number a lender or adviser has quoted, or working out whether a plan that sounded fine in conversation still holds up once it is written down with actual figures. The maths itself is rarely complicated; what is hard is remembering which figures to use and in what order, which is exactly what a dedicated calculator is for.
This tends to come up when comparing two concrete alternatives — two lenders, two savings products, two ways of structuring the same decision — rather than in the abstract. Run both scenarios through the same calculator with the same assumptions and the comparison becomes fair, because the only thing changing between the two results is the number you are actually trying to test.
It is also worth being clear about what a single figure like this can and cannot settle on its own. It answers the specific question the formula was built to answer, and nothing more — a favourable dOTS calculator result does not automatically mean a decision is a good one overall, since plenty of other factors that a formula cannot capture, from personal circumstances to how comfortable a commitment feels, usually matter just as much as the arithmetic. Use the number as one solid input among several rather than the whole of the decision.
In practice, most people arrive at a page like this one having already tried a version of the calculation by hand or in a spreadsheet, and use the calculator here to confirm it rather than replace it. That is a reasonable way to use it — the two should agree to the last decimal place if the same inputs and the same formula are used, and if they do not, the formula shown above is the one to check your own working against first.
Worked example
A concrete run-through, using the values already in the fields:
- Gender: male
- Bodyweight: 80 kg
- Squat: 150 kg
- Bench press: 100 kg
- Deadlift: 180 kg
- Equipment: raw
That gives:
- Total: 430 kg
- DOTS coefficient: 0
- DOTS score: 0
These figures are only the calculator's own starting values, included so the working is visible rather than hidden inside the tool above. Replace them with your own numbers and the same arithmetic applies — nothing about the method changes, only the inputs feeding it.
Reading the result
A higher DOTS score means a stronger performance relative to bodyweight. Because DOTS was fitted to more recent, higher-quality competition data than the 1994 Wilks formula, most federations that switched now treat it as the more accurate cross-weight-class comparison, particularly for lifters well outside the middle of the bodyweight distribution.
Where this goes wrong. The main mistake is expecting the equipment selection to change the score — it will not, by design, since raw and equipped lifting use the same DOTS polynomial and the field is kept purely for labelling your own entry, not as a missing scoring variable. The formula was also fitted specifically to replace Wilks at the low and high ends of the bodyweight range, where Wilks was known to be less accurate, so DOTS and Wilks scores for the same lifter will diverge slightly the further that lifter's bodyweight sits from the middle of the range.
A useful check on any unfamiliar result is to compare it against a rough mental estimate first — round the inputs to convenient numbers and see whether the calculator's answer lands in roughly the same territory. A wildly different figure usually means one of the fields was entered in the wrong unit, most often a percentage typed as a whole number where a decimal was expected, or the reverse.
DOTS is designed as a pure bodyweight-normalization formula and does not have separate coefficients for raw versus equipped lifting — that distinction is handled at the federation and division level (separate raw and equipped rankings), not inside the scoring formula itself. The field is included here so the calculator can label a result, not because it changes the arithmetic.
DOTS was fitted using a larger and more recent set of competition results than the original 1994 Wilks dataset, and it corrects for a known weakness in Wilks where lifters at the very light and very heavy ends of the bodyweight range were scored somewhat inconsistently relative to lifters in the middle of the range.
It returns total. With 80 kg bodyweight, 150 kg squat and 100 kg bench press, that comes to 430 kg. Change any field and the figure moves with it.
Whenever one of the underlying figures changes — a new interest rate, a different balance, an updated term — since the result only reflects what is currently in the fields. There is no need to keep a separate record of past results; the web address for a filled-in version already carries the figures used to produce it.
Not unless a tax rate or a fee is explicitly one of the inputs above. Where it is not, the figure shown is a gross calculation, and any tax due depends on your personal circumstances and current tax rules, which are worth checking separately.
The arithmetic itself is exact — the calculator applies the formula shown above precisely, with no rounding until the final figure is displayed. The uncertainty, where it exists, is entirely in the inputs: an estimated rate or an approximate balance carries that same approximation through to the result.
