Electric Scooter Running Cost Calculator

How much does it cost to run an electric scooter?

Most of the time, much less than petrol per km, but the answer depends on three things: how much energy the scooter uses per km, what each unit of electricity costs you, and how you count the parts that do not show up on a monthly bill. In the default example here (a 3.5 kWh scooter with 120 km of real-world range, ridden 30 km a day for six days a week, in Delhi), electricity costs about ₹0.24 per km, or about ₹186 a month and ₹2,234 a year. A petrol scooter at 50 km per litre costs about ₹2.04 per km in fuel alone.

Electricity is only part of the story. Add servicing and a battery wear allowance and the electric scooter costs about ₹1.80 per km all-in, against ₹2.69 for the petrol scooter. The saving is real, but it is much smaller than the fuel-versus-electricity gap alone suggests.

The formula behind the calculator

Wh per km is found from the battery and the range you really get: battery kWh × usable share × 1000 ÷ real-world range. The default usable share is 0.90 because the battery management system keeps a reserve at the top and bottom of the pack. For the example scooter that is 3.5 × 0.90 × 1000 ÷ 120 = 26.3 Wh per km at the battery. At 88% charging efficiency the meter sees 29.8 Wh per km, and at ₹8 a unit that is ₹0.239 per km.

Use the price of your next unit, not the average

Fixed charges, fuel adjustments and taxes mean the true price of one more unit is often 8% to 30% above the headline energy rate. Slab tariffs make it worse: adding a scooter pushes a household into a higher slab, so the cost of the extra units is the slab rate, not the average of the whole bill. For a typical Indian household the effective rate is about ₹7 to ₹10 per unit, and about €0.23 to €0.37 in much of Europe. The bill helper above divides a bill by its units to get a practical figure.

Charging losses: why the meter reads more than the battery stores

The calculator uses 88% by default. If your own Wh per km figure was measured at the wall socket, choose wall in the advanced box and the loss will not be counted twice. Manufacturer figures are usually battery-side, while many independent road tests measure at the wall.

Real-world range, not claimed range

The headline range of an electric scooter is a test-cycle number. Independent tests usually find 70% to 80% of it in city riding and 60% to 70% on mixed roads, so the presets use typical real-world figures instead. Rider weight, speed, tyre pressure, temperature and riding mode all matter. Sport mode can use about 40% more energy than normal mode and eco mode about 25% less. Cold weather adds 5% to 25% depending on how cold it is, and a heavier load adds a few percent more.

Does an old battery make each km cost more?

No. A battery that holds 80% of its original energy gives 80% of the range, but each km still takes about the same energy. What changes is how often you charge. The advanced section lets you enter battery health, which cuts the range per charge and trims charging efficiency by up to four points.

The battery wear allowance

A lithium battery loses capacity from age and from use. The calculator estimates the yearly loss as calendar loss + (cycles per year ÷ cycle life × 20%), using 3% a year and 1,500 cycles for typical NMC, 2.5% and 2,100 cycles for premium NMC, and 2% and 2,500 cycles for LFP. It assumes the pack is replaced when health falls to 70% (you can choose 80%). At the default distance that is about 7.4 years, so a ₹77,000 pack adds ₹1.11 per km. This is a deferred cost: you may sell the scooter first, or replace only part of the pack. It is shown separately, as a pack that wears out is a real cost even though it never appears on a monthly bill. Our battery lifecycle and replacement cost calculator goes deeper on warranty and timing.

Servicing and wear

Electric scooters have no engine oil, spark plug, air filter or clutch, but tyres, brakes, suspension and a yearly check remain. Published figures for India range from about ₹0.10 to ₹0.90 per km, so the calculator uses ₹0.45 per km for electric and ₹0.65 per km for petrol, and lets you change both. Petrol scooters add oil changes, filters, spark plugs and a belt. For other countries the defaults are typical estimates and you should replace them with a quote.

Petrol comparison: use the mileage you really get

A petrol scooter certified at 59.5 km per litre usually returns about 47 to 55 km per litre in town, so the calculator uses 50. Petrol prices on 31 October 2026 are:

Electricity prices around the world

Household electricity prices vary by a factor of five between countries, and the gap is much bigger once time-of-use plans are included. The US average was 18.56 cents per kWh in March 2026, and the UK price cap from October 2026 is 26.32 pence per kWh. Other countries in the calculator use typical figures that you should check against your own bill: about €0.37 in Germany, €0.23 in France, €0.30 in the Netherlands, €0.31 in Italy, €0.25 in Spain, A$0.35 in Australia, C$0.14 in Canada, ¥0.55 in China and ¥30 in Japan. Public charging is often two to four times the home rate, which is why the advanced section lets you set a public share. Night tariffs such as UK Economy 7 or Indian time-of-day plans can cut the home rate by a third or more, and the off-peak share lets you include them.

Worked examples

The pattern is clear. A rider who covers about 17,000 km a year gains a lot, a delivery rider gains more, and a light user may be better off with petrol because the purchase price and the battery wear are spread over few km. Charging only at public stations removes most of the electricity advantage.

Outside India the same method gives these electricity costs per km for a 2.9 kWh scooter with 55 km of real range (about 54 Wh per km at the wall): $0.010 per km in the United States at 18.56 cents per kWh, £0.014 in the UK at 26.32 pence, and €0.020 in Germany at €0.37. Petrol for a comparable 125 cc scooter at 42 km per litre costs about $0.026, £0.034 and €0.042 per km in the same three markets, so electric is cheaper per km in all three, though the margin in cash terms is small for a rider who covers 9,000 km a year.

Usage profiles

Break-even and total cost of ownership

The calculator gives two break-even figures. The first divides the extra purchase price by the saving per km. The second walks month by month through the cash you spend, with insurance, servicing, electricity or fuel, and any battery replacement, and tells you when the electric total drops below the petrol total. The default example crosses over at about year 8.8. The ownership table also credits resale value using typical depreciation: for electric 50% at 3 years, 30% at 5 and 15% at 8, and for petrol 60%, 30% and 10%. Because the same percentage is applied to a higher price, resale favours the pricier scooter, so look at both figures. You can override both resale values, set a different yearly price rise for fuel and electricity, and add insurance in the advanced section.

Assumptions and limits

• Real-world range is a typical mixed-traffic figure. Your own may differ by 25%.
• Servicing, insurance and resale are typical estimates. Insurance is zero outside India until you enter it.
• Battery wear is linear and ignores warranty claims. A warranty replacement would lower your cost.
• Prices are held flat unless you enter a yearly rise. Subsidies, loans and road tax are not modelled, so enter the price you actually pay.
• Battery swap networks are not modelled directly. To approximate one, set public charging to 100% and enter the swap price per kWh.
