Put your bodyweight and your lifts in below and it works out your Sinclair total. The coefficients are the current IWF ones for the 2025–2028 cycle, so the number you get is the number a scoresheet would give you.

What Are Sinclair Points?
Sinclair points are the gold standard in Weightlifting for working out your rankings in the world. They are adjusted each Olympic Year and are based on the current world records in their respective body weight groups. All you need to do is supply your bodyweight and total (best Snatch + best Clean & Jerk) and points are generated from the information. Please note that Sinclair Points only count from your body weight and total in any one competition.
How do they work it out?
Since June 2025 there are 8 body-weight categories each for senior men and women. Men: 60, 65, 71, 79, 88, 94, 110 and 110+. Women: 48, 53, 58, 63, 69, 77, 86 and 86+. Every category bar the heaviest has an upper limit.
The formula for working out Sinclair Points assumes the lifters who broke the World Records are at the top end of their body weight groups. However the 110kg+ category for men and 86kg+ category for women have no upper limits. The IWF (affiliated with Alberta Weightlifting Association) assign a body-weight for these two super-heavy weight categories. They use mathematical formula to plot a curve that best represents the class.
The formula
Your Sinclair total is your total multiplied by a coefficient worked out from your bodyweight:
Sinclair total = total × 10A(log10(bodyweight ÷ b))²
A and b are constants the IWF resets every Olympic cycle off the current world records. For 2025–2028 they are A = 0.700767794 and b = 201.159007 for men, and A = 0.674107962 and b = 163.918008 for women. Once your bodyweight reaches b the coefficient is 1.0 — the heaviest lifters get no handicap, because there is no heavier class to be compared against.
That is worth knowing if you use another calculator: plenty of them are still running the 2021–2024 numbers, which will quietly give you the wrong answer.
