Electricity Price Calculator - Monthly Power Bill

Estimate your monthly electricity cost from consumption, spot price, markup, and grid rent, with optional Norwegian power subsidy.

Estimated monthly cost
-

How the cost is calculated

The bill consists of the power itself (spot price + markup), grid rent (energy term per kWh + fixed fees), and value-added tax. The variable cost is multiplied by your consumption.

The Norwegian power subsidy covers 90% of the part of the spot price exceeding 73 øre/kWh (excl. VAT). It is calculated including VAT and deducted from the bill.

The numbers are indicative. Actual prices, fees, and subsidy schemes vary by grid company, power contract, and region.

About this tool

The electricity cost calculator computes what you actually pay per month based on consumption (kWh), spot price, retailer markup, grid rent (energy term and fixed fee), VAT and power subsidy. Useful for comparing electricity contracts, planning your budget, understanding your bill, and seeing the effect of switching provider. All in the browser, no data sent out.

How to use it

  1. Enter your monthly consumption in kWh (typically 300–2000).
  2. Fill in spot price, markup, grid rent and fixed fees.
  3. Choose whether to add 25% VAT and subtract the power subsidy.
  4. See monthly cost and breakdown update in real time.

Examples

Typical apartment
Input1000 kWh, spot 80 øre, markup 5, grid rent 40, fixed 200
Outputapprox. NOK 1550/month incl. VAT (without the electricity subsidy)
House with heat pump
Input2500 kWh in winter, spot 150 øre
OutputThe electricity subsidy takes off ~NOK 1200, net approx. NOK 3200/month
The Norwegian power subsidy (2024 rules) covers 90% of the spot price above 73 øre/kWh (incl. VAT). At higher spot prices, your net cost becomes less sensitive to spot fluctuations.

Common use cases

  • Compare electricity contracts with different markup and fixed fees.
  • Estimate how solar panels or a heat pump might pay off.
  • Understand why bills vary so much from month to month.
  • Simulate the effect of spot-price changes on the household budget.
  • See whether the power-subsidy threshold is worth thinking about.

Frequently asked questions

What makes up my electricity bill?
Two parties: the electricity supplier (spot price + markup) and the grid company (grid rent: energy term per kWh + fixed fee). VAT (25% in southern Norway, 0% in the north) is added to both. On top of that come electricity tax to the state (approx. 15 øre/kWh in 2024 outside winter, higher in winter) and an Enova levy (1 øre/kWh). The power subsidy is subtracted at the end when the spot price is high enough.
What is the spot price?
The hourly price on the Nord Pool power exchange, set the day before for each hour. Determined by supply (production) and demand, and varies strongly with weather, reservoir levels, interconnector cables abroad, and power-plant outages. A "spot price" contract follows this curve; "fixed-price" contracts lock the price for 3 months, 1 year, or longer.
What is a normal yearly electricity use?
Norway: apartment 5000–8000 kWh, house without electric heating 8000–15,000 kWh, with electric heating 20,000–30,000 kWh. An EV adds ~3000 kWh/year (15,000 km, 20 kWh/100 km). A heat pump can halve heating consumption. Sweden and Denmark are similar; Germany, France and Spain are much lower (2000–5000 kWh) because heating is often gas or district heating.
Are the numbers from this calculator accurate enough?
They are indicative. The actual bill is affected by hour-by-hour spot price (spot varies per hour, not just per month), power tariff in grid rent (based on peak usage), seasonal variation in electricity tax, and discounts. For exact figures, see your actual bill. For comparing contracts and budget planning, the calculator is more than accurate enough.

Technical background

The model: total = usage · (spot + markup + grid energy term) + fixed fee + subsidy deduction, all in øre/kWh and kroner. VAT (25%) is added at the end (or 0% if you’re in northern Norway). Subsidy deduction = max(0, spot_incl_VAT − 73_øre) · 0.9 · usage. Spot price is normally taken from Nord Pool in real time; here you enter it manually for quick simulation. Note that the Norwegian market is split into 5 price zones (NO1–NO5) which can have very different spot prices at the same time. Because of the 2022–2024 energy crisis, many contracts have "price cap" models where markup varies with spot to limit end-user exposure. All computed in double precision, no external service, no tracking. Tuned to Norwegian conditions; for other countries the subsidy usually doesn’t apply, but the basic structure (usage × price + fixed fee + tax) is the same.
