How it works
How Cycling Watts (FTP) calculadora solves the problem
Think of Cycling Watts (FTP) calculadora as the back-of-the-envelope version of the calculation, only the envelope is a web page and the arithmetic is audited by our test suite.
If a value drops into a red band, act; if it is borderline, track. Measure at the same time of day for consistency — then work out the number and the rest of this page explains what the answer means.
Estimate FTP from a 20-minute test (95% × average power) or ramp test, plus power zones 1–7 for training.
Seeing it on real numbers
A working example keeps the formula honest:
Estimate FTP from a 20-minute test (95% × average power) or ramp test, plus power zones 1–7 for training.
When to use this calculadora
Cycling Watts (FTP) calculadora is aimed at people arriving with questions like these:
- "FTP calculadora"

- "Cycling power zones"
- "What is cycling ftp"
- "How to calculate cycling ftp"
- "Cycling ftp formula"
When to reach for something else
Every tool has an edge where it stops being the right answer. Cycling Watts (FTP) calculadora is no exception:
- For legally binding tax or medical decisions — cross-check with HMRC, NHS or a qualified professional.
- For very large or very small extremes the rounding error outgrows the useful precision.
- When the underlying rate or threshold has changed since the page was last reviewed — always verify with the primary source.
- When the input you have is already a derived figure (net of something) — feeding it in as "gross" will double-subtract.
Traps to steer around
Every time you work out the number for a new scenario, one of these creeps in — it's worth knowing them ahead of time.
- Entering a monthly figure into an annual field (or vice versa).
- Forgetting a leading zero on decimals (.5 instead of 0.5 breaks some inputs).
- Trusting a single reading when the underlying number naturally fluctuates.
- Comparing two answers that used different assumptions — always re-run both.
- Skipping the formula box. If you don’t understand the method, the answer is just a vibe.
The sources behind the numbers
Where the maths needs an external authority, we cross-check against:
- British Cycling
- TrainingPeaks
Works well alongside
If this question keeps coming up for you, the same cluster of tools usually comes next:
- VO₂ Max calculadora — Estimate VO₂ max from the Cooper test, Rockport walk test, or max HR — with fitness-category banding.
- Heart Rate Zone calculadora — Work out your max heart rate and the five training zones (recovery, easy, tempo, threshold, VO₂ max) using age-adjusted formulas.
- Running Pace calculadora — Convert between pace, speed and time over any distance — plus split times for 5K, 10K, half and full marathon targets.
