How it works
Enter your monthly electricity usage in kWh, the total price you actually pay per kWh, and any fixed monthly fee on the bill. If your contract or invoice separates taxes, network charges, or surcharges, add them into the per-kWh figure before comparing results.
Monthly cost = (kWh usage × price per kWh) + fixed monthly fee. Annual = monthly × 12.
300 kWh at 1.50 kr/kWh with a 79 kr fixed fee → 529 kr/month, about 6,350 kr/year. If usage rises to 450 kWh in winter at the same price, the monthly total becomes 754 kr.
Comparing electricity contracts, checking how much of the bill comes from usage versus fixed fees, building a winter budget, or testing whether lower consumption would make a noticeable difference.

FAQ
What price per kWh should I use?+
Use the real total you pay per kWh on the bill. If taxes, network charges, or supplier surcharges are listed separately, include them so the estimate is comparable to what you actually pay.
Why include a fixed fee?+
Many electricity contracts include a fixed monthly charge even when usage is low. Including it shows whether a cheap-looking per-kWh rate still leads to a realistic monthly total.
Is the result exact?+
No. It is only as accurate as the usage and price you enter. Real bills can vary by season, meter readings, taxes, network fees, and whether your contract price changes over time.
Does this work for both apartments and houses?+
Yes. The calculator is not tied to a property type. What matters is using your own usage level, your real all-in price per kWh, and any fixed fee from the contract.
