Wilks Calculator (IPF GL Points)
Score a powerlifting total or bench press against bodyweight with the IPF GL formula, the points system the IPF uses in place of Wilks.
Result
IPF GL points: 132.796
Points compare a lift with the IPF’s elite reference for that bodyweight; 100 is that reference level.
- IPF GL coefficient
- 0.189738

How to use the Wilks Calculator (IPF GL Points)
- Choose the equation for men or women, classic or equipped lifting, and a full powerlifting total or bench press only. The IPF publishes separate coefficients for each of those eight combinations.
- Enter bodyweight and the weight lifted, in kilograms or pounds.
- Read the IPF GL points and the coefficient behind them.
The IPF GL formula
The International Powerlifting Federation published the IPF GL formula in May 2020. It gives each lifter a coefficient from their bodyweight, then multiplies the result by it:
coefficient = 100 ÷ (A − B × e^(−C × bodyweight))points = coefficient × resultBodyweight and result are in kilograms, and e is the base of natural logarithms. A, B and C depend on the category:
| Category | A | B | C |
|---|---|---|---|
| Men, equipped total | 1236.25115 | 1449.21864 | 0.01644 |
| Men, classic total | 1199.72839 | 1025.18162 | 0.00921 |
| Men, equipped bench | 381.22073 | 733.79378 | 0.02398 |
| Men, classic bench | 320.98041 | 281.40258 | 0.01008 |
| Women, equipped total | 758.63878 | 949.31382 | 0.02435 |
| Women, classic total | 610.32796 | 1045.59282 | 0.03048 |
| Women, equipped bench | 221.82209 | 357.00377 | 0.02937 |
| Women, classic bench | 142.40398 | 442.52671 | 0.04724 |
The IPF states the formula for bodyweights of at least 40 kg for men and 35 kg for women. Entering pounds is fine; the page converts to kilograms first.
Where the coefficients come from
The IPF derived them by regression on the best results of elite lifters at its international and European championships, and on world and European records, from 2011 onward. The shape of the curve encodes three assumptions the IPF describes: a heavier lifter lifts more in absolute terms, lifts less per kilogram of bodyweight, and approaches a physical ceiling. The document says the parameters drift over time and plans to refit them on a four-year cycle; its cover gives the period 2020 to 2023, and the IPF still links it as the current table.
What the score is for
IPF GL points answer one question: how does a result compare with the elite reference level for a lifter of that bodyweight and category? That makes it useful for ranking across weight classes at a meet or tracking your own relative strength as your bodyweight changes. It does not grade a lift as good or bad, and the page does not offer any bands for it.
With your numbers
- The formula uses kilograms: bodyweight 83.01 kg, result 699.89 kg (1,543 lb lifted)
- Coefficient = 100 ÷ (A − B × e^(−C × 83.01)) = 0.13842, to six decimals
- 0.13842 × 699.89 = 96.879 points
Quick reference
Points compare a lift with the IPF’s elite reference for that bodyweight; 100 is that reference level.
| Example | IPF GL points |
|---|---|
| Men, classic, 74 kg, 600 kg total | 88.086 |
| Men, classic, 93 kg, 750 kg total | 98.116 |
| Men, classic bench, 105 kg, 200 kg | 89.553 |
| Women, classic, 63 kg, 400 kg total | 87.513 |
| Women, equipped, 57 kg, 500 kg total | 95.84 |
| Men, 198 lb, 1,500 lb total | 90.546 |
Common questions about the Wilks Calculator (IPF GL Points)
- Is this the Wilks formula?
- No. The page keeps the familiar name, but it calculates IPF GL points, which the International Powerlifting Federation has used for its best-lifter rankings since 1 May 2020. Wilks is an older bodyweight formula with different coefficients, and its scores are on a different scale, so the two numbers cannot be compared directly.
- What does a score of 100 mean?
- The IPF set the formula up so that 100 points is the level of an average elite lifter at that bodyweight, in that category. A score of 90 is 90 percent of that reference level. It is a way to compare lifters of different sizes, not a rating of anyone's training.
- Why are there different coefficients for classic and equipped lifting?
- The IPF's statistical analysis found that the lifter's sex, the use of supportive equipment and the type of competition all greatly affect results. So rather than one curve for everyone, it fitted separate parameters for every combination, and a classic total and an equipped total get different coefficients at the same bodyweight.
- Why does my score go down when I get heavier?
- It does not, if your lifts go up with your bodyweight. The coefficient falls as bodyweight rises, because heavier lifters are expected to lift more. The points only rise if the result rises faster than the coefficient falls.
- Will these match a meet score sheet?
- They should. The IPF rounds the coefficient to six decimal places before multiplying it by the result, and this page does the same. Official general score sheets show the points to three decimals, as here.
