How it works
How Cycling Watts (FTP) calculadora solves the problem
Every Cycling Watts (FTP) calculadora on this page runs the same cycling ftp calculadora logic a chartered accountant or coursework tutor would scribble on the back of an envelope — just faster, and reproducible.
Calculating a cycling ftp calculadora by hand takes five minutes and one stray digit to redo. Cycling Watts (FTP) calculadora runs it in a breath, keeps the working visible, and you get the same number every time you reload.
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.
On this page you will see Power zones, Cycling performance and FTP treated as first-class terms — each one is linked to the calculators and references that use it, so you can follow the thread without retyping queries into a search bar.
If it helps, jump straight to the Health hub or compare with the VO₂ Max calculadora and the Heart Rate Zone Calculator — those two calcs are the ones readers usually open right after this page.
One scenario, fully unpacked
Put the method down against a real situation and the sequence becomes obvious:
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"
- "20 minute FTP test"
- "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.
- Ignoring the unit multiplier (k, M, %, basis points) on the input and feeding the raw number in anyway.
- Assuming the default settings match your context — check the calc's assumptions box before trusting the figure.
- Re-entering the result of a previous step as an input without keeping the full-precision number in front of you.
- Reading a negative answer as an error when the maths is telling you the inputs are in the wrong order.
- Cross-comparing to a tool that uses a different formula family (e.g. Mifflin vs Harris-Benedict) without saying so.
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 Calculator — 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.
