How much does an air conditioner cost to run in Spain?

Split and window air conditioners typically draw 1,000 to 4,000 watts, with a mid-size unit around 2,000 W. What you pay depends on the wattage, how many hours a day it runs, and your electricity rate. In a Spanish summer, air-con is usually the single biggest driver of the bill — and across much of the country, summer, not winter, is the most expensive season. Enter your unit's wattage, your daily hours and your own rate to see the cost per hour, day, month and year.

How we calculate this

kWh/day = (W / 1000) × hours
cost/month = kWh/day × (days/week ÷ 7) × 30.44 × rate
cost/year = kWh/day × (days/week ÷ 7) × 365.25 × rate

Set 24–26°C and pre-cool at cheaper midday hours — each degree lower adds about 7%.
