Calculate your Olympic weightlifting total and Sinclair coefficient. Compare snatch and clean & jerk performances across weight classes.
Calculate your Olympic lifting total and Sinclair score for snatch and clean & jerk.
The Olympic Weightlifting Calculator computes your competition total (snatch + clean & jerk) and Sinclair coefficient—the standard for comparing Olympic lifters across different bodyweight categories. Used by the International Weightlifting Federation (IWF), the Sinclair score determines the best overall lifter.
Olympic weightlifting is the ultimate expression of explosive power. The snatch and clean & jerk require a unique combination of strength, speed, mobility, and technique. Your Sinclair score normalizes performance so that a 56kg lifter can be fairly compared to a 109kg+ superheavyweight.
A and b are gender-specific coefficients updated by the IWF each Olympic cycle based on world records.
| Level | Snatch (× BW) | C&J (× BW) | Total (× BW) |
|---|---|---|---|
| Beginner | 0.5x | 0.7x | 1.2x |
| Intermediate | 0.8x | 1.0x | 1.8x |
| Advanced | 1.1x | 1.3x | 2.4x |
| Elite | 1.4x+ | 1.7x+ | 3.0x+ |
An 81 kg male lifter with 120 kg snatch and 150 kg clean & jerk: Total = 270 kg. Using 2024 Sinclair coefficients, this yields a Sinclair score of approximately 310 points.

Sinclair = Total × 10^(A × (log₁₀(BW/b))²). Coefficients A and b are gender-specific, updated by IWF each Olympic cycle. Allows comparison across weight categories.
Snatch is typically 78-83% of clean & jerk. If snatch is <75% of C&J, work on overhead strength/technique. If >85%, focus on pulling strength and front squat.
As bodyweight multiplier: Beginner 1.2x, Intermediate 1.8x, Advanced 2.4x, Elite 3x+. An 81kg male at advanced level totals ~195kg (85 snatch + 110 C&J).
