Why does your all-in price differ from my bill?

Usually for one of three reasons: your real spot price differs from the one you typed, your retailer charges a monthly fee or surcharges you did not add to the mark-up, or your grid company has a power charge or changed its price after 1 January. Compare line by line with the bill; write to us if the grid price looks wrong.

How often are grid fees updated?

The Energy Markets Inspectorate publishes grid companies’ prices once a year, as of 1 January. We load the file when it appears and check it against the companies’ own price lists when someone reports a change. Authority charges for 2026 are set to SEK 140 for every grid, since some companies reported the old amount.

Is my pasted price list used anywhere else?

No. A script in your browser reads it and it disappears when you close the page. It is neither sent to us nor stored. Nor do we fetch any spot prices ourselves, at build time or while you visit, because they may not be republished without a licence.

Elpriskollen method 2026: how the all-in price is worked out

Elpriskollen works out what a kilowatt-hour costs a Swedish household once everything is in: the retail energy price, the grid company’s transfer fee, energy tax and VAT, plus the fixed monthly fees. Every tax rate and threshold sits in a parameter file dated 12 October 2026, with a source for each block. Grid prices come from the Energy Markets Inspectorate’s (Ei) compilation for 136 grid areas and contract statistics from Statistics Sweden (retrieved 12 October 2026). No figure is typed by hand into the texts: they are computed from the same files the calculators use.

The formula

All-in price per kWh = (spot price + mark-up + transfer fee + energy tax) × (1 + 25%). Every part is entered before VAT; VAT goes on the sum, tax included, exactly as on the bill. A negative spot price lowers the total but the tax stays.

Example: spot 80 öre, mark-up 5 öre, Umeå Energi’s transfer fee of 18.1 öre for a 16 A house, energy tax 36.0 öre. The sum before VAT is 139.1 öre, VAT 34.8 öre, total 173.9 öre per kWh.

Energy tax and VAT

Energy tax is 36.0 öre per kWh before VAT from 1 January 2026 under chapter 11, section 3 of the Energy Tax Act (1994:1776). In the municipalities listed in section 4, the grid company deducts 9.6 öre, so households pay 26.4 öre. The Act indexes the amount to prices from 2027; a March 2026 government memorandum proposes keeping it at 36.0 öre instead. That had not been decided when this page was updated, and we change the value only once a decision is made. VAT is 25% according to the Swedish Tax Agency.

Grid fees

Every year Ei collects grid companies’ charges for standard customers: a 16 A flat using 2,000 kWh, a 16 A house using 5,000 kWh, a 20 A house using 10,000 or 20,000 kWh and a 25 A house. For each case there is a fixed fee, authority charges, a variable price and an annual total before VAT. We derive an average price per kWh as (total − fixed parts) ÷ consumption, which weights peak and off-peak rates when a grid has two prices. Where Ei shows no price, often because the grid uses a power charge for houses, we show nothing rather than guess. Ei’s open data may be reused freely under the authority’s terms.

Statistics Sweden price data

The pre-filled spot price and the history come from Statistics Sweden’s Electricity prices and contracts: the monthly retail price by contract type, bidding zone and type of home, before energy tax, VAT and grid fee, mark-up included. Example: a variable contract for a house without electric heating in SE3 in August 2026 was 86.9 öre. Statistics Sweden publishes under CC0. Latest month in the file: 2026M08.

Spot prices

We show no spot prices. Day-ahead prices belong to the power exchange; ENTSO-E’s list of data free for re-use does not include them, and the exchange sells display licences. You type or paste your own price. The calculator reads the list in your browser, recognises öre, kronor and euros per megawatt-hour and handles each quarter hour separately.

Tests

Ei’s standard cases are recomputed and checked against the regulator’s totals, for example Umeå Energi: SEK 3,234 a year before VAT for a 16 A house with SEK 140 of authority charges.
Statistics Sweden values are checked against published figures, and the energy tax in its half-year household statistics must equal the parameter.
Lowest, highest and average come from the same list and are tested so that the lowest can never exceed the highest.
Every mini-calculator is run with defaults and with empty and maximum fields, and must never return NaN.

Limits

Power charges are included only where they appear in Ei’s standard cases. You add the retailer’s monthly fee, electricity certificates and guarantees of origin yourself. Grid companies may change prices during the year. Electricity support is paid afterwards and does not change the price per kWh. Found an error? kontakt@totalelpris.se.
