Mini-split cost calculator
How Much Does a Mini-Split Cost to Run?
Estimate mini-split electricity cost using input power, daily run time, and your local electricity price.
Cost estimate
Calculate your electricity cost
Estimated energy use0 kWh/day
Estimated monthly energy0 kWh/month
Cost = watts ÷ 1,000 × hours used × electricity price.
Example
How the starting estimate works
At 1,000 watts for 8 hours per day, the starting example uses 8 kWh per day. Replace the wattage with an observed or rated input value for your system.
Real-world use
Inverter systems rarely stay at one power level.
Mini-splits modulate output as heating or cooling demand changes, so rated or maximum input power may overstate average draw. A smart meter or energy monitor can provide a better real-world average.
