EV vs Petrol Bike Total Cost of Ownership & Savings Calculator

How to Use the EV vs Petrol Bike Cost Calculator

The calculator starts with a typical case: a 125cc petrol scooter against a mid-range 3 kWh electric scooter, 30 km a day, six days a week, in Delhi. Change what is different for you. Results update as you type.

1. Enter how you ride. Daily kilometres and riding days decide almost everything. 30 km on 26 days is 780 km a month.
2. Pick the petrol bike type or enter your own mileage, on-road price and yearly service cost. Use the mileage you actually get, not the company claim.
3. Choose your city. The petrol price fills in from the rates of 21 September 2026. You can type a different price.
4. Describe the electric scooter. Battery size in kWh, real range, the on-road price after the PM E-DRIVE subsidy, your home electricity rate and how often you will use public chargers.
5. Open “Extras” if you want more detail. Insurance, yearly price rise, charger loss, battery replacement and resale value already have sensible defaults.
6. Read the result. The top card tells you which bike is cheaper over your ownership period and by how much. Below it are the break-even month, a cost chart, a full cost table, a year-by-year table and three “what if” checks.

Two numbers on the result are worth a look even if you skip the rest. Break-even month is when the EV’s lower running cost has paid back its higher price. Minimum daily distance is the least you need to ride for the EV to come out cheaper within the years you plan to keep it. If you ride less than that, the petrol bike is the cheaper choice.

EV vs Petrol Bike Running Cost

Running cost is what you spend on fuel or electricity for every kilometre you ride. This is where electric two-wheelers win clearly. A petrol scooter giving 45 km per litre costs ₹2.27 per km in Delhi at ₹101.96 a litre. A 3 kWh electric scooter giving 95 km of real range costs about ₹0.29 per km when charged at home at ₹8 a unit. That is about 8 times cheaper.

The gap depends on your city’s petrol price, since the EV side changes only with your electricity rate:

Petrol figures assume 45 km per litre. EV figures assume a 3 kWh battery, 95 km real range and 12% charger loss. Running cost does not include the purchase price, service, insurance or battery wear. Those come into the total cost of ownership further down.

Electric Bike Charging Cost vs Petrol Fuel Cost

A full charge takes a little more electricity than the battery size, because the charger and battery lose 10–15% as heat. Bajaj puts charger efficiency at 85–90%. So a 3 kWh battery draws about 3.4 units from your meter, not 3.

Swipe the table sideways to see every column.

Compare that with petrol. Filling a 5.3-litre scooter tank in Delhi costs about ₹540 and takes you about 240 km at 45 km per litre. Covering the same 240 km on a 3 kWh electric scooter at home costs about ₹69.

Home charging vs public charging

• Home: domestic tariffs in most states run from about ₹4 to ₹10 a unit, depending on the state and your slab. Charging adds units at your highest slab, so use the top rate on your bill.
• Public AC chargers: usually ₹10–₹18 a unit.
• Public fast chargers: about ₹18–₹30 a unit, sometimes with a session or parking fee.

Charging only at public fast chargers can cost three times as much as home charging. The EV is still cheaper to run than petrol, but the saving shrinks. Pick “Always public chargers” in the calculator if you have no parking spot with a plug.

How to Calculate EV Cost per Kilometer

Worked example: 3 kWh battery, 12% charger loss, ₹8 a unit, 95 km real range.

1. Units per charge = 3 ÷ 0.88 = 3.41 units.
2. Cost per charge = 3.41 × ₹8 = ₹27.27.
3. Cost per km = ₹27.27 ÷ 95 = ₹0.29 per km, or about ₹29 per 100 km.

Use the real range, not the IDC figure on the brochure. The Indian Driving Cycle is a slow lab test. Riders usually get 70–80% of it, and less at high speed, with a pillion or in sport mode. If your scooter shows its own efficiency in Wh/km, cost per km is simply Wh/km ÷ 1,000 × ₹ per unit, plus the charger loss.

For an exact figure, read your meter before and after one full charge. The difference is the true units your scooter uses, with the loss already included.

How to Calculate Petrol Bike Cost per Kilometer

Worked example: ₹101.96 a litre in Delhi and 45 km per litre gives 101.96 ÷ 45 = ₹2.27 per km.

The mileage you get on the road is usually 15–25% below the company’s claim, more in heavy traffic. To measure it, fill the tank to the brim, reset the trip meter, ride as usual, then fill to the brim again. Kilometres ridden ÷ litres added is your real mileage.

A high-mileage 100cc commuter bike is the hardest petrol vehicle for an EV to beat on price, because it is cheap to buy and already cheap to run.

EV vs Petrol Bike Monthly Running Cost

Monthly cost is daily distance × riding days × cost per km. With 26 riding days a month, petrol at ₹101.96 and 45 km/L against an EV at ₹0.32 per km (mostly home charging):

Swipe the table sideways to see every column.

Add service cost spread over the year and the monthly gap grows by about ₹296 at 30 km a day (about ₹5,500 a year for a petrol scooter against ₹1,800 for an EV at 10,000 km a year). The calculator shows your full monthly cost including service.

EV vs Petrol Bike Annual Running Cost

Yearly running cost = energy for the year + service for the year. Service here starts at ₹5,500 (petrol) and ₹1,800 (EV) for 10,000 km a year and moves with distance, since oil changes, brake pads and chains wear by the kilometre. Insurance is separate because the first year is paid inside the on-road price.

Swipe the table sideways to see every column.

At 30 km a day the yearly saving is about ₹21,743. That is the number that pays back the EV’s higher price. If petrol rises 3% a year, as the calculator assumes by default, the saving grows a little each year.

EV vs Petrol Bike Maintenance Cost

An electric motor has far fewer wearing parts than an engine. Ather puts average service cost for its scooters at about ₹1,500 a year, against about ₹6,000 for a 125cc petrol scooter. Chetak owners report ₹300–₹500 per service and TVS iQube about ₹680 per service.

Swipe the table sideways to see every column.

The one big EV maintenance cost is the traction battery. Replacement prices today are about ₹19,000–₹25,000 per kWh, which means ₹45,000–₹50,000 for a 2.2 kWh pack, ₹60,000–₹75,000 for a 3 kWh pack and over ₹1 lakh for a 5 kWh pack. Most brands give 3–8 years of battery warranty, and some sell extended plans. Many batteries still hold 70–80% of their range after the warranty ends, so a replacement is not certain. The calculator lets you include it or leave it out.

EV vs Petrol Bike Total Cost of Ownership

Total cost of ownership (TCO) is everything you pay from the day you buy to the day you sell, minus what you get back.

What goes into the on-road price

• GST: 5% on electric two-wheelers. Petrol two-wheelers up to 350cc pay 18% since the GST cut of 22 September 2025, down from 28% plus cess. That cut narrowed the price gap between petrol and electric models.
• PM E-DRIVE subsidy: ₹2,500 per kWh, capped at ₹5,000 or 15% of the ex-factory price, for e-two-wheelers priced up to ₹1.5 lakh ex-factory. It is now extended to 31 March 2028, subject to funds. The dealer deducts it.
• Registration and road tax: battery electric vehicles are exempt from registration fees nationally, and many states waive or cut road tax on EVs. Petrol bikes pay state road tax, often 8–12% of the price.
• Insurance: the IRDAI third-party premium is ₹457 a year for e-two-wheelers up to 3 kW and ₹607 for 3–7 kW, against ₹714 for 75–150cc and ₹1,366 for 150–350cc petrol bikes. New two-wheelers come with a 5-year third-party cover in the on-road price.

Worked example: 5 years, 30 km a day

Swipe the table sideways to see every column.

In this example the electric scooter costs ₹84,324 less over 5 years, even after a faster loss in resale value. The all-in cost per km is the fairest single number to compare, because it includes the purchase price and resale.

How Long Does It Take to Recover the Higher EV Purchase Cost?

In the default case the price gap is ₹25,000 and the EV pays it back in month 14. The table below shows how the payback time changes with the price gap and your daily distance (26 riding days, Delhi petrol, mostly home charging, service scaled to distance):

Swipe the table sideways to see every column.

Two things move payback the most: how far you ride and how big the price gap is. A rider doing 15 km a day who pays ₹60,000 extra for a premium EV may not break even before selling it. The calculator’s “minimum daily distance” line tells you where that point is for your numbers. Payback ignores resale value, so it is a cash-flow view; the total cost of ownership above includes resale.

EV vs Petrol Bike Cost Over 5 Years

Year by year for the default case (30 km a day, 26 days a month, petrol and electricity rising 3% a year). Year 1 includes the on-road price.

Swipe the table sideways to see every column.

A negative figure means the petrol bike is still ahead. After 5 years the EV has saved ₹87,735 in cash. After resale value is counted the gap is ₹84,324, because the EV is worth less when sold. At 46,800 km the battery is well inside the usual 8-year or 80,000 km life, so no replacement is counted. Keep the EV past 8 years or ride much more, and the calculator adds one.

What Factors Affect EV vs Petrol Bike Cost?

• Daily distance. The biggest factor by far. Savings grow with every kilometre, while the EV’s price premium is fixed.
• City petrol price. Petrol costs ₹14 a litre more in Hyderabad than in Delhi, which adds about 30 paise to every petrol kilometre.
• Your electricity slab. Charging adds units at your highest slab. In states with steep slabs, a large home bill can push the rate above ₹10 a unit.
• Home or public charging. Public fast charging at ₹18–₹30 a unit can triple the EV’s running cost.
• Real mileage and real range. Traffic, speed, weight and tyre pressure affect both. Always use real-world numbers.
• Purchase price gap. After the 2025 GST cut on petrol bikes, the gap narrowed. Subsidy, state road-tax waivers and dealer offers change it further.
• Battery warranty and life. A replacement inside your ownership period can wipe out several years of savings. Check the warranty in both years and kilometres.
• Resale value. Used EVs sell for less today than used petrol bikes. Keeping the bike longer reduces the effect.
• Price changes. Petrol prices follow crude oil and taxes; electricity tariffs change each year with state regulators.
• Battery rental (BaaS). Some brands sell the scooter without the battery and charge a monthly rental. This lowers the purchase price and moves battery risk to the company, but adds a fixed monthly cost.
