Calculadora de coste eléctrico

Introduce la potencia de un aparato en vatios, cuántas horas funciona al día y tu precio por kWh para ver el coste diario, mensual y anual.

Electricity Cost

What a device costs to run per year

Cost per day1.08
Cost per month32.40
Cost per year394.20
Energy per year1,314 kWh

How it works

  • kWh al día = vatios × horas ÷ 1.000.
  • El consumo en espera de todos los aparatos de una casa puede sumar un 5–10% a la factura.

Worked example: a 2,000 W heater, 4 hours a day, €0.30/kWh

  1. 1Daily use: 2,000 × 4 ÷ 1,000 = 8 kWh.
  2. 2Daily cost: 8 × 0.30 = €2.40.
  3. 3Yearly: 2.40 × 365 = €876 if used every day.

€2.40 per day · €72 per month · €876 per year

What common appliances cost per hour (€0.30/kWh)

ApplianceTypical powerCost per hour
LED bulb9 W€0.003
Laptop50 W€0.015
Fridge (average)100 W€0.03
Dishwasher cycle1,800 W≈ €0.54 per cycle
Tumble dryer2,500 W€0.75
Electric heater2,000 W€0.60

Fridges and freezers cycle on and off — their average draw is much lower than the rated power.
