Compound Score Calculator
Find out where you rank against professional benchmarks — from recreational through to WorldTour level — using the peer-reviewed Leo & Spragg methodology.
Category
Your highest average power held for exactly 5 minutes — from a race, test, or hard training effort.
Use your weight on race day, lightly clothed.
Optional — for extra insights
Functional Threshold Power. Your estimated 1-hour best power, or 95% of your 20-min power test.
How it's calculated
Formula
5-min Power (W) × 5-min W/kg
= W² / kg
Published by Leo, Spragg, Wakefield & Swart (2022) in the Journal of Science and Cycling, the compound score is the single metric with the highest predictive capacity for professional race success — outperforming FTP, absolute power, and W/kg individually.
It captures both aerodynamic ability (absolute watts) and climbing ability (W/kg) simultaneously — the two physical demands that decide races. The same formula applies equally to men and women.
