Appliance Running Cost Calculator

Every electrical appliance in your home contributes to your electricity bill, but how much does each one actually cost to run? This calculator helps you estimate the daily, monthly, and annual running cost of any appliance based on its wattage, how long you use it each day, and your electricity price.

Common Appliance Costs

High-consumption appliances like electric ovens (2,000โ€“2,500 W), tumble dryers (2,000โ€“3,000 W), and space heaters (1,000โ€“2,500 W) can add significantly to your bill when used frequently. Even smaller appliances add up over time: a 100 W TV running 5 hours a day costs around 450 kr per year at Danish electricity prices. Standby power consumption for all household electronics combined typically accounts for 5โ€“10% of total electricity use.

Choosing Energy-Efficient Appliances

When buying new appliances, the EU energy label (A to G rating) gives a quick overview of energy efficiency. An A-rated fridge-freezer may use only 100โ€“150 kWh per year, while an older model could consume 300โ€“400 kWh. Over a 10โ€“15 year lifespan, the savings from choosing an efficient model can easily exceed the price difference at purchase.

Frequently Asked Questions

Which appliances use the most electricity?

The biggest energy consumers are typically electric ovens (2,000-2,500 W), tumble dryers (2,000-3,000 W), space heaters (1,000-2,500 W), and electric kettles (2,000-3,000 W). However, total cost depends on how many hours each appliance is used per day.

How much does standby power cost?

Standby power consumption for all household electronics typically accounts for 5-10% of total electricity use, costing a Danish household 500-1,500 kr per year. Using power strips with switches and unplugging unused devices can eliminate most standby waste.

How do I read the EU energy label?

The EU energy label rates appliances from A (most efficient) to G (least efficient). It also shows annual energy consumption in kWh. An A-rated fridge may use only 100-150 kWh per year, while an older D-rated model could use 300-400 kWh, a significant cost difference over a 10-15 year lifespan.

How do I calculate the kWh consumption of an appliance?

Use the formula: Watts / 1,000 ร— Hours = kWh. Find the appliance's wattage (usually on the back), divide by 1,000 to get kW, and multiply by the number of hours it is on. For example, a 2,000 W oven running for 1 hour uses 2 kWh, costing about 5 kr at 2.50 kr/kWh.
