Fast charging vs home charging — what is cheapest?

For EV owners in Norway in 2026, the question is not whether an EV is cheaper than fossil — it is. The question is rather how much you can save by choosing the right charging strategy. The difference between home charging and fast charging can amount to many thousands of kroner per year.

Let us look at what actually pays off for different types of EV users.

The price difference in a nutshell

In 2026, the typical price picture in Norway looks like this:

• Home charging: 1.00-2.00 kr/kWh (including grid tariff and taxes)
• Fast charging (registered): 3.49-5.49 kr/kWh
• Fast charging (drop-in): 5.49-6.99 kr/kWh

This means that a kilometer driven on home-charged electricity costs about 18-36 ore, while a kilometer driven on fast-charged electricity costs 63-100 ore. Both are far cheaper than petrol (about 130-160 ore per km), but the difference between home and fast charging is still significant.

Three everyday scenarios compared

To make the comparison concrete, we have calculated three typical usage patterns. All scenarios are based on an EV driven 15,000 km per year with a consumption of 18 kWh/100 km — a total electricity consumption of 2,700 kWh per year.

Scenario 1: The commuter with their own home

Profile: Lives in a detached house with their own charger. Drives 50 km to work daily. Charges almost exclusively at home overnight.

Scenario 2: The apartment dweller without home charging

Profile: Lives in an apartment without the option for home charging. Dependent on public chargers — a mix of normal charging at work/shopping centres and fast charging.

For the apartment dweller without home charging, the annual cost is more than double. Still, it is cheaper than petrol, which would cost around 13,000-14,000 kr for the same distance.

Scenario 3: The mixed user

Profile: Lives in a terraced house with a charger. Home charges daily, but drives a lot of long trips during holidays and weekends and uses fast charging regularly.

The mixed user ends up in the middle — and can save the most by optimising fast charging costs with subscriptions and price comparison.

Hidden costs to consider

The price comparison above only shows the electricity cost per kWh. Several factors affect the total cost:

Home charging

• Charger: Investment cost of 8,000-15,000 kr (one-time expense)
• Increased grid tariff: Higher capacity charge if you charge at high power during daytime
• Electricity contract: Type of contract affects the price (spot vs fixed price)

Fast charging

• Start fee: Some operators charge a start fee per charging session
• Parking fee: Many fast chargers are located at paid parking
• Per-minute pricing: Some operators charge per minute instead of per kWh, which penalises cars with lower charging speed
• Idle fee: Some operators charge extra if you do not move your car after charging is complete

Is it worth installing a home charger?

In short: yes, almost always. Here is a simple calculation:

Without home charger (fast charging only): 2,700 kWh x 4.50 kr = 12,150 kr/year

With home charger (95% home): 2,565 kWh x 1.40 kr + 135 kWh x 4.50 kr = 4,199 kr/year

Annual saving: approx. 7,950 kr

With an installation cost of about 12,000 kr, you earn back the home charger in under two years. Over the car's lifetime, you save tens of thousands of kroner.

Tips for reducing fast charging costs

Even though fast charging is more expensive, there are several ways to reduce the costs:

1. Register for free in the apps of the operators you use — always avoid drop-in prices
2. Consider a subscription if you fast charge more than 2-3 times per month
3. Compare prices between stations nearby — price differences can be significant
4. Plan your charging stops on long trips to choose the cheapest stations
5. Charge to 80% instead of 100% — charging speed drops above 80%, and you pay more per kWh with per-minute pricing models

Conclusion: what pays off for you?

The answer depends on your living situation:

• Do you have the option for home charging? Install a home charger — it is hands down the best investment you can make as an EV owner.
• Do you live in an apartment without a charger? Look for charging options at work or in the housing cooperative, and use subscriptions to reduce fast charging costs.
• Do you drive a lot of long trips? A charging subscription can save you several thousand kroner per year.
