EV vs Petrol: The Real 3-Year Running Cost in Latvia (2026)
An honest running-cost breakdown — fuel or charging, road tax and service over 3 years. Strictly what it costs to keep a car, not what it costs to buy.
Most "EV or petrol" calculations mix up two very different things: what a car costs to buy and what it costs to keep. This article is only about the second — the running cost over 3 years in Latvia: fuel or charging, road tax and service. We do not promise fixed numbers for your car; we show how they form and put them side by side, so you can enter your own figures in our calculators and work it out yourself. Short answer up front: an EV usually has a lower running cost — but it is worth adding up honestly, not assuming.
In this article:
Energy: charging vs fuel per 100 km
The biggest day-to-day line is what the car runs on. Take a typical EV consumption of ~18 kWh per 100 km and a home electricity price of ~€0.20/kWh — that is roughly €3.60 per 100 km. A comparable petrol car, say in the VW Golf or Škoda Octavia class, at ~7 l/100 km and ~€1.70/l costs about €11.90 per 100 km.
At 15,000 km a year that is a markedly lower energy cost on the EV side — about €540 a year for home charging versus about €1,785 a year for petrol. Over three years the difference adds up to thousands of euros, and that is just one of the three parts of the math.
An honest caveat: public fast chargers cost more than home charging, so the biggest benefit comes when you can charge at home or at work. If you have no home-charging access, the real energy gap will be smaller — which is exactly why it is worth entering your own numbers rather than relying on an average.
Road tax and annual fees
The second annual line is the vehicle operating tax. In Latvia it has historically been calculated on parameters where an EV sits more favourably, because it has no emissions. In practice that means an EV's annual tax tends to be lower than that of a comparable petrol car.
We deliberately do not state a fixed sum, because the rates change year to year and depend on the specific car. So the right step is to check your own car in the tax calculator and the 2026 tax guide, not to rely on an estimate. Even a small annual difference becomes a noticeable sum over three years in the total.
Service and wear: fewer parts
The third line is scheduled service and wear — and here the EV advantage is mechanical, not a marketing trick. An EV has no combustion engine, so there are no oil changes, spark plugs, timing belt, clutch or exhaust system that wear out over time and need replacing.
Regenerative braking (the motor slows the car and recovers energy into the battery) spares the brake pads and discs significantly — many EV owners replace them far less often than on a petrol car. What remains is tyres, cabin filter, brake fluid and software updates.
The practical takeaway: the scheduled-service bill over 3 years tends to be lower on the EV side. That does not mean "zero cost" — tyres and maintenance are still real lines — but the total tends to be lower than servicing a comparable petrol car.
3-year running cost side by side
We put all three lines together over 3 years and 15,000 km a year (45,000 km in total). These are illustrative estimates to show how the numbers form — for your own figures, use the calculators. As EV examples we take two real models, but this is strictly about running cost, not the purchase price:
| Line (3 years, 45,000 km) | Electric | Petrol (Golf/Octavia class) |
|---|---|---|
| ⚡ Energy / fuel | ~€1,620 (home charging) | ~€5,355 (petrol) |
| 🧾 Road tax (3 years) | Usually lower — check the calculator | Usually higher — check the calculator |
| 🔧 Scheduled service | Lower (no oil, brakes last longer) | Higher (oil, plugs, belt, brakes) |
| 📊 Running-cost trend | Lower day-to-day cost | Higher day-to-day cost |
The energy figures are calculated on the assumptions above (18 kWh/100 km @ €0.20/kWh; 7 l/100 km @ €1.70/l). Tax and service are shown as a trend, not a fixed sum, because they depend on the specific car and change year to year. So this is not a "final number" but a map of how to add up your own — with our calculators.
EV examples (running-cost context only)
Electric SUV · 218–258 HP · 475 km WLTP · ~80 kWh CATL · 3-year / 100,000 km warranty, serviced in the EU. As an electric SUV it falls under the lower-energy and less-frequent-service logic above.
Sedan · 673 HP · 830 km CLTC · 101 kWh CATL · 800V · 3-year / 100,000 km warranty, serviced in the EU. A large battery and 800V charging mean your charging access (home vs public) especially affects your €/100 km.
Prices are given only to identify the model — this section is about running cost, not the purchase price. Both models come with a 3-year / 100,000 km factory warranty, serviced in the EU, which matters specifically for the running-cost math (see below).
What buyers should weigh honestly
Running cost is only one side. For the math to be honest, there are two things that must not be glossed over:
Home-charging access
The biggest energy benefit requires the ability to charge at home or at work. If you only have public charging, the real gap against petrol will be smaller. It is the first question to ask yourself before the math.
Value uncertainty
The EV resale market is still younger than the petrol market, so future value is less predictable. It is not part of the day-to-day running cost, but it affects total ownership — worth putting into the math honestly.
Winter consumption
In the cold an EV's range and consumption worsen, so the real annual energy cost will be a little higher than a summer estimate. This applies to all EVs — plan with a buffer.
What a used EV with warranty changes
The 3-year running-cost math has one biggest unknown — the high-voltage system and the battery. This is exactly where warranty changes everything. If a used EV still has its factory warranty (for example, 3 years / 100,000 km, serviced in the EU), then this largest potential expense is covered, and the 3-year cost becomes more predictable.
By contrast, a used EV with no warranty is riskier: a single major repair can wipe out the entire energy and service saving. So compared with a petrol car, it is worth looking not only at price and consumption, but also at whether the high-voltage part is still covered.
