Wind Turbine Profit Calculator

Your details

Horizontal-axis turbines are the standard three-blade design. Vertical-axis turbines work better in turbulent or urban settings.
For a HAWT, this is the blade length (= rotor radius). For a VAWT, enter half the rotor diameter.
m
Total turbines in your installation. Revenue and costs are multiplied accordingly.
Power coefficient (Cp). Typical modern turbines: 35-45%. The Betz limit sets the theoretical maximum at 59.3%.
%
Mean wind speed at hub height. Power scales with the cube of speed, so even small differences matter greatly.
m/s
Standard sea-level air density is 1.225 kg/m³. At altitude or in hot climates, use a lower value.
kg/m³
The rate at which you sell or offset electricity. US average is around $0.13/kWh for commercial consumers.
USD/kWh
Total equipment cost for all turbines. A utility-scale 1 MW turbine typically costs $1.2-$1.6 million.
USD
Civil works, grid connection, and commissioning. Often 15-20% of turbine cost.
USD
Typical O&M for a utility-scale turbine runs about 2% of capital cost per year.
USD/yr
Modern turbines are rated for 20-25 years of operation.

Your setup produces 401.3 kW.

  • Your installation generates an estimated $430,984 net profit per year after maintenance costs.
  • The investment pays back in about 3.5 years against a 20-year project life.
  • Total ROI over 20 years is 474.6%.
  • You offset roughly 1356.9 tons of CO₂ per year, equivalent to removing 295.0 average passenger cars from the road.

Next stepWind speeds above 6 m/s are well-suited to wind energy generation. Because power scales with the cube of wind speed, even a 10% speed increase lifts output by about 33%.
