Air conditioner electricity cost per month
A 1.5 kW AC scheduled for eight hours daily at 55% average compressor load uses about 198 kWh in 30 days. Multiply that energy by your applicable electricity rate for the monthly cost.
Cooling schedule
One AC, three monthly scenarios.
Each scenario uses 1.5 kW electrical input. The tariff remains separate so energy and price assumptions never get confused.

Keep energy and price visible.
Monthly kWh = input kW × hours/day × days × average compressor loadThen multiply monthly kWh by the applicable unit rate. For time-of-use tariffs, calculate peak and off-peak portions separately.
Why the month changes
Cooling demand is not constant.
Weather and humidityHotter, wetter periods usually increase compressor activity.
Room and buildingSun exposure, leakage, insulation, size and occupancy change heat gain.
Set point and maintenanceLow temperatures, blocked airflow and equipment condition can increase runtime.
