IPF GL Points Calculator

The IPF GL Points Calculator computes Goodlift (GL) points for raw powerlifting totals using the International Powerlifting Federation's body-weight adjustment formula. GL points allow lifters of different body weights to compare performances on a common scale, where a higher score indicates greater relative strength.

How IPF GL Points Calculator works

This calculator applies the IPF Goodlift formula to a powerlifting total (the sum of best squat, bench press, and deadlift) and body weight. The formula uses sex-specific coefficients to normalise totals across weight classes. A 500 kg total at 80 kg body weight will score differently than the same total at 100 kg, reflecting the non-linear relationship between body mass and strength potential. The tool outputs a single GL score that can be compared against other lifters' scores regardless of weight class.

The formula

IPF GL Points = (100 / (a − b × e^(−c × bodyweight_kg))) × total_kg, where (a, b, c) are sex-specific coefficients published by the IPF. For male lifters the raw coefficients are a = 1199.72839, b = 1025.18162, c = 0.00921. For female lifters they are a = 610.32796, b = 1045.59282, c = 0.03048. The exponential term adjusts for the diminishing returns of added body mass at heavier weights. The coefficients here are the official raw powerlifting set published on the IPF's formula page; the IPF publishes separate coefficients for equipped lifting and for bench-only events, which this calculator does not implement. Worked through with the defaults: at 80 kg male bodyweight the denominator evaluates to 709.1, so a 500 kg total scores 100 × 500 ÷ 709.1 = 70.52 GL points. The denominator has a readable meaning: it is the formula's projected elite raw total at that bodyweight (709 kg at 80 kg male, 442 kg at 60 kg female), so GL points can be read as a percentage of elite-level performance. The IPF's own results platform, goodlift.info, scores every sanctioned meet with this formula.

Where this method is most accurate

The IPF GL formula is calibrated to raw powerlifting totals in sanctioned competition conditions: knee sleeves, belt, and wrist wraps allowed but no supportive shirts or suits. Equipped totals entered into this tool will produce artificially low GL scores because the raw coefficients do not account for the mechanical advantage of gear. The formula's accuracy is highest within the typical competitive body-weight range (approximately 50–150 kg for males, 40–110 kg for females). Totals from gym lifts, estimated maxes, or single-lift PRs may not align with three-lift meet totals due to differences in fatigue, judging standards, and attempt selection.

What this tool does not do

This calculator does not provide training programming, nutrition guidance, or medical assessments. It does not predict future performance, diagnose strength imbalances, or account for age, training experience, or injury history. The tool does not convert equipped totals to raw equivalents; equipped lifts require the IPF's equipped-specific coefficient sets, which are not implemented here. GL points are descriptive statistics for comparing meet results, not prescriptive targets for individual lifters.
