A calculator to estimate what an air conditioner really consumes, and what that means on your bill.
Unlike a heater, an air conditioner does not draw its rated power continuously: a thermostat switches the compressor off once the target temperature is reached, then switches it back on as it drifts. It's this real running rate, not the power printed on the spec sheet, that determines the day's consumption.
This tool applies a physical model (power draw, daily hours of use, heat intensity for your region) to give a realistic consumption range, converted into an electricity cost per day, per month and over the full season based on the price per kWh you enter.
The result is always given as a range, never as a single figure, and comes with a direct comparison against a fan to measure the cost gap between the two solutions.
Consumption over the daily usage period1360 to 1840 Wh
For comparison, a fan (50 W) over the same hours would cost €0.10/per day.
Unlike a heater, an air conditioner does not draw its rated power continuously: a thermostat switches the compressor off once the target temperature is reached, then switches it back on as it drifts. The running rate used here depends on the gap between the reference outside temperature (chosen city) and a target inside temperature fixed at 24°C, not a measurement of your specific room: insulation, sun exposure and floor area also matter, see our power calculator to refine those.
