FTP Calculator (Cycling)
Calculate Functional Threshold Power (FTP) from a 20-minute all-out cycling test. FTP represents the maximum power output (watts) you can sustain for one hour. Enter your average power from the 20-minute test to estimate FTP and power training zones.
Formula
FTP = 20-minute average power × 0.95
- FTP = 20-minute average power × 0.95 (conservative estimate)
- Zone 1 Recovery: <55% FTP (active recovery rides)
- Zone 2 Endurance: 56–75% FTP (aerobic base building)
- Zone 3 Tempo: 76–90% FTP (sustainable threshold work)
- Zone 4 Threshold: 91–105% FTP (FTP definition range)
- Zone 5 VO₂max: 106–120% FTP (high-intensity intervals)
- 20-min test should be performed after warm-up on flat terrain; power meter or smart trainer required for accuracy.
Example Calculation
Inputs
- Average power for 20-min test: 250 W
Suppose you enter: Average power for 20-min test = 250. The calculator applies the formula (FTP = 20-minute average power × 0.95) and shows all output values below. Change any input field to immediately see how the result changes.
