When buying a car, it is easy to focus on one number: the price you pay at the dealership. But that number is only the beginning of what a car actually costs.
Over the next five years, there will be fuel or charging expenses, servicing, insurance, tyres, repairs and eventually the value the car retains when you sell it. Put all of these together and the calculation can look very different from the original purchase price.
This is where electric vehicles can make an interesting financial case. The initial cost of an EV may not always be lower than a comparable petrol car, but its day-to-day running costs can change the equation over a longer ownership period.
So, are EVs cheaper to own than petrol cars over five years? The honest answer is that it depends on how the car is used. Looking at the total cost of ownership provides a much better answer than comparing ex-showroom prices alone.
Start with the cost of buying the car
The purchase price remains an important part of the calculation. Depending on the model and segment, the EV car price in India can be higher or comparable to that of a petrol-powered vehicle.
This difference matters because a higher upfront price means that the owner has more money tied up in the vehicle from day one.
However, the purchase price should be treated as one component of ownership cost, not the entire calculation.
A better comparison asks what happens after the car is purchased. How much will it cost to cover 10,000, 12,000 or 15,000 kilometres every year? How much will be spent on energy? What routine maintenance will be required? And what could the vehicle be worth after five years?
These questions give a more realistic picture of affordability.
Fuel versus charging changes the running-cost equation
For a petrol car, fuel is one of the biggest recurring expenses. Every kilometre driven consumes petrol, and the total amount spent depends on fuel efficiency, annual mileage and the price paid for fuel.
An EV uses electricity instead. Its energy consumption is expressed in kilowatt-hours per 100 kilometres.
Consider a simple example. A petrol car delivering 15 km per litre and travelling 12,000 km annually would consume around 800 litres of petrol in a year. Over five years, that would amount to approximately 4,000 litres.
An EV covering the same distance does not have a petrol bill. Instead, its electricity consumption depends on the vehicle’s efficiency and the amount of energy required to charge the battery. Charging losses should also be considered when calculating the actual electricity consumed.
The cost can vary depending on whether the vehicle is charged at home or at public charging stations. Electricity tariffs also differ by location and usage.
This means there is no single five-year saving figure that applies to every EV owner. The higher the annual driving distance, the more important the energy cost becomes in the overall calculation.
Maintenance is another part of the equation
Running costs are not limited to energy.
Petrol cars have internal combustion engines with components and fluids that require periodic servicing. Depending on the vehicle and service schedule, this can include engine oil, oil filters, spark plugs and other engine-related components.
An electric vehicle has a different mechanical setup. It does not require engine oil or spark plug replacement, for instance. This can reduce the number of routine engine-related maintenance tasks.
That does not mean an EV requires no maintenance. Tyres, brakes, suspension components, cabin filters, wipers and other consumables still need attention.
The braking system can also behave differently. Regenerative braking allows the electric motor to help slow the vehicle, potentially reducing reliance on conventional friction brakes in certain driving conditions.
For a five-year comparison, the most useful approach is to look at the scheduled maintenance requirements of the specific vehicles being compared rather than assuming that every EV or petrol car will have identical servicing costs.
The battery should be considered, not feared
For many buyers, the battery is the biggest question mark surrounding EV ownership.
The battery is a major component of an electric vehicle, and its condition can influence the vehicle’s long-term value and performance. Battery performance can be affected by factors such as usage, charging behaviour, temperature and age.
However, battery replacement should not automatically be treated as a routine five-year ownership expense. It is not equivalent to changing engine oil or replacing a regular service item.
Buyers should instead examine the battery warranty, coverage conditions and recommended charging practices for the vehicle they are considering.
This is particularly important when calculating total ownership cost because an assumption about a full battery replacement can significantly distort the five-year comparison if it is not actually required.
Depreciation can change the final answer
There is another cost that is often overlooked when people compare EVs and petrol cars: depreciation.
Imagine spending ₹15 lakh on a vehicle. If it is worth ₹8 lakh after five years, the effective cost associated with depreciation is ₹7 lakh. The exact figures will vary, but the principle remains the same.
This is why resale value needs to be included in a proper total cost of ownership calculation.
Factors such as vehicle age, mileage, condition, demand and the wider used-car market can influence resale value. The amount recovered when the vehicle is sold effectively reduces the net cost of owning it.
A five-year comparison that ignores resale value can therefore give an incomplete picture.
How much you drive matters more than you might think
Annual mileage is one of the biggest variables in the calculation.
Someone who drives 5,000 km a year will naturally spend less on fuel or charging than someone covering 20,000 km. As a result, the potential running-cost difference between an EV and a petrol car will have a different impact on each owner’s finances.
This is why a useful five-year calculation should start with an honest estimate of your monthly or annual driving distance.
If you use the car for occasional weekend trips, the higher initial price of an EV may take longer to offset through running-cost savings.
If you have a long daily commute, energy costs become a much larger part of your overall ownership bill.
The same EV can therefore represent very different value propositions for two different drivers.
Charging access matters too
There is also a practical question that can affect the economics: where will you charge?
Home charging can make everyday EV ownership more convenient and allows owners to use their domestic electricity supply, subject to the applicable tariff and charging setup.
Public charging is useful when travelling longer distances but charging costs can vary between locations and operators.
For someone with easy access to home charging, the five-year ownership calculation may look quite different from that of someone who depends heavily on public charging.
Therefore, when researching EV cars in India, it is worth considering charging access alongside the vehicle’s price and claimed efficiency.
What should a five-year calculation include?
A useful comparison does not need to be complicated. Start with the major costs.
For a petrol car, consider:
Five-year ownership cost = Purchase price + fuel + maintenance + insurance + tyres and other expenses – resale value
For an EV, consider:
Five-year ownership cost = Purchase price + charging + maintenance + insurance + tyres and other expenses – resale value
The comparison becomes even more useful when the same annual mileage, ownership period and assumptions are applied to both vehicles.
A total cost of ownership calculation can then show whether the difference in purchase price is offset by lower running costs over time.
Are EVs cheaper after five years?
Sometimes, yes. But not automatically.
An EV can have a higher initial purchase price while benefiting from potentially lower energy and routine maintenance costs. Over five years, particularly for drivers who cover substantial distances, these recurring expenses can have a meaningful impact on the overall ownership bill.
A petrol car may still work out better for someone who drives very little, has limited access to convenient charging or prioritises a lower initial purchase price.
There is no universal five-year winner because ownership costs depend on the vehicle, mileage, charging arrangements, maintenance, insurance and resale value.
The better question is not simply, “Which car is cheaper to buy?”
It is, “Which car costs less across the five years I expect to own it?”
That shift in perspective can make the decision much clearer. Instead of looking at the price on the day of purchase, calculate what you are likely to spend throughout the ownership period and subtract what the car may be worth when you sell it.
For buyers comparing electric and petrol vehicles, that is the number that deserves the most attention.
