Cycling Power Calculator
Calculate cycling power output based on speed, weight, grade, and environmental factors
About this calculator
The Cycling Power Calculator determines the exact power output (measured in watts) required to maintain a specific cycling speed under various conditions. By factoring in your body weight, bike weight, road gradient, wind resistance, and environmental conditions, this tool provides accurate power calculations essential for training optimization, race planning, and performance analysis. Whether you're a competitive cyclist tracking FTP improvements or a recreational rider planning climbs, understanding power requirements helps optimize pacing strategies and training zones.
How to use
Enter your total weight (rider + bike), desired cycling speed, and road gradient percentage. Add environmental factors like wind speed, air temperature, and elevation if known for increased accuracy. The calculator will instantly display the required power output in watts to maintain your specified speed under those conditions.
Frequently asked questions
What factors affect cycling power calculations?
Key factors include total weight, speed, road gradient, wind resistance, air density, rolling resistance, and aerodynamic drag coefficient.
How accurate are cycling power calculator results?
Results are highly accurate when all variables are entered correctly, typically within 5-10% of actual power meter readings.
Can I use this calculator for indoor cycling?
Yes, for indoor cycling set gradient to 0% and minimal wind speed to calculate trainer resistance requirements.
