EV vs petrol running cost
Pick a petrol bike and an electric model. We use the specs already in our database — no invented figures — and show you cost per kilometre, monthly saving and how long the price difference takes to pay back.
Change the fuel and tariff rates to match your city — the defaults come from site settings, not a live feed.
We cannot calculate this pair
Our database is missing mileage for the petrol bike and battery capacity for the EV and range for the EV. Rather than guess a number, we leave it blank — please pick another model.
Questions people ask
How is electric cost per km calculated?
We divide the usable battery capacity (kWh) by the claimed range to get kWh per km, multiply by your electricity tariff, then divide by charging efficiency to account for losses at the charger and in the battery.
Are claimed range figures realistic?
Usually not. Manufacturer range is measured in ideal conditions. Real-world range is often 20-30% lower, which raises the real cost per km. Where we have a verified real-world figure we show it on the model page.
Does this include battery replacement?
No. Battery replacement cost and timing vary far too much to assume a number, so we leave it out rather than guess. Factor it in separately if you plan to keep the vehicle beyond the warranty.
