Cycling Calories Calculator
Estimate calories burned cycling from power output or speed.
About Cycling Calories Calculator
Because human cycling efficiency sits near 24 per cent and a calorie is 4.184 kilojoules, the two nearly cancel: kilojoules of work and kilocalories burned are approximately the same number. That coincidence is why power meters can report either unit almost interchangeably, which is unique to cycling among endurance sports.
Formula
Cycling Calories
Energy input = mechanical work ÷ metabolic efficiency, converted to calories
- metabolic efficiency
- Humans convert about 20 to 25 per cent of energy into pedal work
- kilojoule coincidence
- At 24 per cent efficiency, kilojoules and calories are nearly equal
Worked example
With the default values below, Cycling Calories Calculator returns Calories Burned of 1,010.1. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- These figures are estimates based on population-average formulas and are intended for training and recreational planning only. They are not medical advice. Consult a qualified health professional before starting or changing an exercise programme, particularly if you have an existing medical condition.
- This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions
How is Cycling Calories calculated?
Energy input = mechanical work ÷ metabolic efficiency, converted to calories Because human cycling efficiency sits near 24 per cent and a calorie is 4.184 kilojoules, the two nearly cancel: kilojoules of work and kilocalories burned are approximately the same number.
Why does Cycling Calories matter?
That coincidence is why power meters can report either unit almost interchangeably, which is unique to cycling among endurance sports.
