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

EIA state rates
About$0.00per hour
About$0.00per day
About$0.00per month
About$0.00per year
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.
