Cycling Functional Threshold Power (FTP) & Coggan 7-Zone Calculator
Calculate your cycling Functional Threshold Power (FTP in Watts) and Watts-per-Kilogram (W/kg) from a 20-minute time-trial test to define Coggan training power zones (Zone 1 to Zone 7).
Calculator Inputs
Live Real-TimeFunctional Threshold Power (FTP)
Power-to-Weight Ratio (W/kg)
3.17 W/kg
Zone 2 Base Endurance Ceiling
171 Watts
Detailed Calculation Breakdown
Calculation Methodology
FTP (Watts) = Average 20-Min Test Power * 0.95. W/kg = FTP / Body Weight in kg.
Important Legal & Educational Disclaimer
Standard cycling FTP protocol discounts average 20-minute power output by 5% (0.95 multiplier) to reflect sustainable 60-minute aerobic capacity.
