Wilks & DOTS Calculator

The Wilks & DOTS Calculator turns a powerlifting total into a single score that can be compared fairly between lifters of different bodyweights. Enter your bodyweight and total — or your squat, bench and deadlift — and the tool computes your Wilks, Wilks-2 (2020) and DOTS scores side by side, places your DOTS on a strength-level gauge, and draws an equivalence curve showing exactly what total you would need at any other bodyweight to match your result.

What is the Wilks Coefficient?

The Wilks coefficient, created by Robert Wilks, is a bodyweight- and sex-based multiplier applied to your total (in kilograms). Lighter lifters lift less absolute weight but receive a larger coefficient, so the resulting Wilks score lets a 60 kg lifter and a 120 kg lifter be compared on the same scale. For years it was the default "best lifter" metric in most federations.

What is DOTS?

DOTS is a more recent scoring system that follows the same idea — total multiplied by a bodyweight coefficient — but uses an updated fourth-order polynomial fitted to modern competition data. Many federations switched from Wilks to DOTS because it is considered slightly fairer at the extreme light and heavy ends of the bodyweight range. A higher DOTS score always means a stronger performance for your bodyweight.

Wilks & DOTS Formulas

Each score multiplies your total in kilograms by a coefficient built from a polynomial of your bodyweight \( x \) in kilograms.

The coefficient sets \( a \ldots f \) differ by sex and by scoring system. Wilks-2 (2020) uses the same shape as Wilks but with revised coefficients and a numerator of 600, so its numbers run noticeably higher than classic Wilks.

DOTS Strength Level Standards

DOTS scores map to broad strength levels. These bands are a practical guide for drug-tested lifters, not official cut-offs.

Comparing Totals Across Bodyweights

Because a score equals your total (kg) multiplied by the coefficient for your bodyweight, you can invert it: total needed = your score ÷ the coefficient at a new bodyweight. The equivalence curve in the results does exactly this, plotting the total required across a range of bodyweights to hold your DOTS score constant. It is the clearest way to answer questions like "how much would I need to total if I moved up a weight class?"

Wilks vs DOTS vs IPF Points

Wilks is the classic metric and still widely quoted. Wilks-2 is its 2020 update. DOTS is favoured by many federations today for its handling of light and heavy lifters. A fourth common system, IPF GL Points, is used specifically at IPF events and is calibrated separately by equipment and event. All of them share the same goal: comparing strength relative to bodyweight on one number.

How to Use This Calculator

1. Select sex and units: Choose Male or Female and pick kilograms or pounds.
2. Enter your bodyweight and total: Type your competition bodyweight and total, or fill in your squat, bench and deadlift and let the tool add them up.
3. Click Calculate: See your Wilks, Wilks-2 and DOTS scores together.
4. Compare across bodyweights: Read your strength level on the gauge and use the equivalence curve and table to see the total needed at any other bodyweight.

Frequently Asked Questions

What is the Wilks coefficient?

The Wilks coefficient is a number, based on your bodyweight and sex, that is multiplied by your powerlifting total (in kilograms) to produce a single score. It lets lifters of different bodyweights be compared fairly, because lighter lifters move less absolute weight but receive a larger coefficient.

What is DOTS?

DOTS is a newer scoring formula that also converts a total into points using a bodyweight-based coefficient, but with an updated polynomial that many federations adopted in place of Wilks. Like Wilks, a higher DOTS score means a better strength-to-bodyweight performance.

What is the difference between Wilks and DOTS?

Both turn your total into points relative to your bodyweight, but they use different coefficient curves. DOTS uses a fourth-order polynomial fitted to more recent data and is considered slightly fairer for very light and very heavy lifters, which is why it replaced Wilks in several federations. Wilks-2 is a 2020 revision of Wilks that uses updated coefficients and a numerator of 600.

Is a higher Wilks or DOTS score better?

Yes. For every scoring system a higher score is better and represents a stronger performance for your bodyweight. As a rough DOTS guide, under 200 is beginner, 300 is a solid intermediate, 400 is advanced, 500 is elite and 600 or more is world class.

Do I enter my total in kilograms or pounds?

You can enter either. The Wilks and DOTS formulas are defined for kilograms, so if you choose pounds the calculator converts your bodyweight and total to kilograms before scoring, then displays your results. The final Wilks and DOTS points are the same regardless of the unit you type in.

How is a total needed at another bodyweight worked out?

Because a score equals your total in kilograms multiplied by the coefficient for your bodyweight, the tool inverts that relationship: total needed = your DOTS score divided by the coefficient at the new bodyweight. The equivalence curve plots this for a whole range of bodyweights so you can see how the required total scales.
