Cycling Wattage Calculator
Calculate your FTP (Functional Threshold Power), power-to-weight ratio (W/kg), and training power zones for cycling.
Our Cycling Wattage Calculator helps you understand your cycling fitness level. Here's how to use it:
Step 1: Select your FTP test type (20-minute, 8-minute, ramp test, or 60-minute).
Step 2: Enter your average power output during the test in watts.
Step 3: Enter your body weight in kg or lbs.
Step 4: Click 'Calculate' to see: - Your estimated FTP (Functional Threshold Power) - Power-to-weight ratio (W/kg) - Performance category based on Coggan's Power Profile - All 7 power training zones with watt ranges
FTP Calculation: - 20-min test: FTP = Average Power × 0.95 - 8-min test: FTP = Average Power × 0.90 - Ramp test: FTP = Last Minute Power × 0.75 - 60-min test: FTP = Average Power (direct)
Power-to-Weight Ratio: W/kg = FTP (watts) / Body Weight (kg)
Coggan's 7 Power Zones: - Zone 1 (Active Recovery): <55% FTP - Zone 2 (Endurance): 56-75% FTP - Zone 3 (Tempo): 76-90% FTP - Zone 4 (Threshold): 91-105% FTP - Zone 5 (VO2max): 106-120% FTP - Zone 6 (Anaerobic): 121-150% FTP - Zone 7 (Neuromuscular): >150% FTP
