Question 1

Is an electric car really cheaper to run?

Accepted Answer

Yes. Electricity costs roughly €3-5 per 100 km for an EV, while petrol costs €8-12 per 100 km. Combined with lower maintenance (no oil changes, less brake wear), EVs save €1,000-2,000 per year on running costs alone.

Question 2

How long does it take for an EV to pay for itself?

Accepted Answer

With current price differences, an EV typically pays back its higher purchase price in 4-7 years through fuel and maintenance savings. Driving more kilometers per year shortens the payback period.

Question 3

What electricity price should I use?

Accepted Answer

Use your average all-in electricity price including grid fees and taxes. In Estonia, this is typically 12-18 c/kWh on a stock contract. With Elewatt smart charging, you can reduce this to 8-12 c/kWh by charging during the cheapest hours.

Question 4

Are the maintenance cost estimates accurate?

Accepted Answer

The calculator uses European average maintenance costs. EV maintenance is typically €300-500/year (tire rotation, cabin filter, brake fluid). Petrol car maintenance is €800-1,200/year (oil changes, filters, spark plugs, brake pads, exhaust system, timing belt).

Question 5

Does the calculator account for battery degradation?

Accepted Answer

The basic calculator does not include battery replacement costs. Most modern EV batteries retain 80%+ capacity after 200,000 km and come with 8-year warranties. Battery replacement costs (€5,000-15,000) are rare within a typical ownership period.
