How to calculate your cost per 100 km
Understanding your real driving cost is simpler than you might think. The formula is straightforward:
your consumption per 100 km × the cost of your energy (fuel or electricity)
For example:
A petrol or diesel car uses litres per 100 km, multiplied by the price per litre
An electric vehicle uses kWh per 100 km, multiplied by your electricity price
This gives you a clear cost per 100 km, making it easy to compare different powertrains on equal footing. Why does this matter? Because once you know your own number, you can directly compare it to alternative options and instantly see where savings are possible.
Want to see how this compares to your current car? Use our calculator to easily determine your cost per 100 km, whether you’re driving electric or an ICE vehicle, and discover how much you could potentially save by switching.

Save more than just on energy
Lower driving costs don’t stop at energy. With electric driving, you also save significantly on maintenance. Electric vehicles are designed with far fewer moving parts than traditional combustion engines. No oil changes, fewer wear components, and reduced mechanical complexity all mean fewer things can break, resulting in lower maintenance costs over time.
That’s why our electric models, such as the BYD ATTO 3 EVO, have a recommended maintenance interval of just every 2 years, helping you save both time and money.
