Official IPF relative-strength scoring
Calculate IPF GL points from bodyweight and competition result using the published International Powerlifting Federation constants for men or women, classic or equipped, and powerlifting or bench press.
Competition scoring
Select the exact category that matches the performance. For powerlifting, enter the three-lift total. For bench press, enter the bench press result.
Official methodology
The published GL method first calculates a bodyweight coefficient, then multiplies that coefficient by the competition result in kilograms.
Formula: GL coefficient = 100 ÷ (A − B × e−C×BW); GL points = coefficient × result. The published definition applies from 40 kg bodyweight for men and 35 kg for women.
When pounds are entered, bodyweight and result are converted to kilograms before scoring.
A, B and C depend on sex category, classic/equipped status, and powerlifting/bench press event.
The result is a points score intended to compare performances across bodyweights within the scoring system.
| Category | A | B | C |
|---|---|---|---|
| Men — Equipped Powerlifting | 1236.25115 | 1449.21864 | 0.01644 |
| Men — Classic Powerlifting | 1199.72839 | 1025.18162 | 0.00921 |
| Men — Equipped Bench Press | 381.22073 | 733.79378 | 0.02398 |
| Men — Classic Bench Press | 320.98041 | 281.40258 | 0.01008 |
| Women — Equipped Powerlifting | 758.63878 | 949.31382 | 0.02435 |
| Women — Classic Powerlifting | 610.32796 | 1045.59282 | 0.03048 |
| Women — Equipped Bench Press | 221.82209 | 357.00377 | 0.02937 |
| Women — Classic Bench Press | 142.40398 | 442.52671 | 0.04724 |
What the result means
A higher score means a larger competition result after the GL coefficient is applied. GL points can help compare performances across bodyweights, but the selected event and equipment category must match the result being scored.
Three-lift powerlifting uses the squat + bench press + deadlift total. Bench press scoring uses the bench result alone and different constants.
The official tables publish separate constants for classic and equipped categories. Do not swap them when comparing scores.
IPF GL replaced the earlier IPF formula from 1 May 2020 and is the scoring method published by the IPF for sanctioned events.
Worked example
At 46.50 kg bodyweight with a 397.5 kg total, the women’s classic GL constants produce a coefficient of about 0.28018 and approximately 111.37 points. Published IPF score sheets display the coefficient rounded for reporting, so displayed meet values can differ slightly at the hundredth.
Tool guide
Use these tool-specific notes to understand the method, enter better data, interpret the output, and apply the result appropriately.
IPF GL points scale a lifting result by bodyweight using the official sex-specific coefficient set. The formula is designed for comparison within the relevant IPF scoring context.
Use kilograms or let the calculator convert pounds. The scoring equation itself uses bodyweight in kilograms and applies official minimum bodyweight conditions.
Use the result type that matches the comparison you are making. A powerlifting total and a single-lift performance should not be mixed as though they represent the same event score.
Compare athletes using the same GL implementation and event context. Equipment category, rules, successful attempts, and meet conditions still matter beyond the numeric score.
Frequently asked questions
Practical answers about this tool's inputs, method, results, limitations, and common real-world use.
IPF GL points are a bodyweight-adjusted scoring method published by the International Powerlifting Federation to compare competition performances across bodyweights.
Yes. The published table has separate men’s and women’s A, B and C constants for each event/equipment category.
The equation structure is the same, but the constants are different. Always select the equipment category that matches the performance.
Select Bench Press and enter the bench press result being scored. Do not enter a three-lift total when using bench press constants.
Yes. Pound inputs are converted to kilograms internally because the official GL formula is defined with bodyweight and result in kilograms.
No. Wilks and IPF GL are different relative-strength scoring systems with different equations and scales. Do not directly compare the numerical scores as if they were the same ruler.
They can be calculated from a result value, but comparisons should remain within the same event type. Do not compare a bench-only GL score directly with a three-lift total as if the event demands were identical.
The official coefficient document specifies lower bodyweight conditions for the formula. Enforcing those limits avoids extrapolating the scoring model into unsupported ranges.
Yes. The calculator converts pounds to kilograms before applying the official formula, so the underlying score uses the correct bodyweight unit.
Use the actual bodyweight associated with the lifting result, not the upper limit of the weight class. The GL coefficient is calculated from the athlete’s real bodyweight entered in kilograms.
