Watts per Kilogram Calculator
The most argued-about number in cycling. Enter your FTP and weight to see where you sit.
Need both a valid FTP and weight to work this out.
Your ratio
–
| Category | W/kg (FTP) |
|---|---|
| Untrained | 0.0–1.9 |
| Fair / new to structured training | 2.0–2.9 |
| Moderate (Cat 5 / social racer) | 3.0–3.7 |
| Good (Cat 4) | 3.8–4.4 |
| Very good (Cat 3) | 4.5–5.1 |
| Excellent (Cat 1–2) | 5.2–5.8 |
| Exceptional (domestic pro) | 5.9–6.6 |
| World class (WorldTour) | 6.7+ |
Benchmarks are a rough guide based on commonly-cited amateur/pro FTP power profiles — they skew toward male open-category riders, so treat them as a reference point, not a verdict. Bodyweight, terrain and how you got your FTP number all move where you land.
Chasing a higher number by losing weight has diminishing (and sometimes unhealthy) returns — the honest gains for most of us are in the watts, not the kilos.
