How this calculator works
AC cost is estimated from its average power draw, daily operating time and your electricity rate. Inverter AC units often cycle and may consume less than their maximum rated power.
How to use the result
Change one input at a time to compare scenarios. This helps you see which factor has the biggest effect on your total cost or savings.
Results are estimates for planning and comparison. Actual costs can differ because of taxes, tariffs, fees, usage patterns, equipment efficiency and local conditions.
Frequently asked questions
Does inverter AC use less electricity?
Often yes, especially after the room reaches the target temperature, because the compressor can run at reduced output.
Should I use rated watts or measured watts?
Measured average wattage gives a better estimate when available.
Why does weather matter?
Hotter outdoor temperatures usually increase compressor runtime and total energy use.
