EV vs Petrol/Diesel TCO Calculator
Compare five-year total cost of ownership for EV and ICE vehicles with the same usage pattern.
Problem
Vehicle decisions go wrong when the sticker price is over-weighted and the running cost is under-weighted.
Promise
Compare electric and ICE ownership cost over time using purchase price, running cost, maintenance, and subsidy.

Vehicle setup
Usage and operating cost
Main answer
₹2,17,000
The EV is cheaper by about ₹2,17,000 over 5 years in this usage pattern.
The comparison adds purchase price, running cost, maintenance, and subsidy across the chosen ownership horizon.
EV total cost
₹19.0L
Purchase price net of subsidy plus running and maintenance cost.
ICE total cost
₹21.2L
Purchase price plus fuel and maintenance cost.
Running-cost gap
₹4,32,000
Fuel spend minus electricity spend over the same horizon.
Purchase premium
₹3,00,000
EV upfront premium after subsidy.
EV versus ICE total cost
EV running cost
₹1,08,000
Electricity spend over the full horizon.
ICE running cost
₹5,40,000
Fuel spend over the full horizon.
Ownership horizon
5 years
Shorter horizons make purchase premium matter more.
How to read this tool
This is a planning model, not a final quote. Use it to understand the direction and size of the trade-off before committing.
Adjust the inputs to test optimistic and conservative scenarios instead of relying on one default answer.
Why the result leans this way
Usage is the main swing factor
Higher monthly kilometres magnify the running-cost advantage of the EV and shorten the time needed to recover the purchase premium.
A short ownership horizon can keep ICE ahead
If you will not keep the vehicle for long, the EV purchase premium may not have enough time to pay back.

Frequently asked questions
When does the EV usually start to win?
EVs strengthen when monthly usage is high, maintenance stays low, and the purchase premium is not too large for the horizon you expect to keep the vehicle.
How should I use the ev vs petrol/diesel tco calculator result?
Run it with conservative and aggressive assumptions. If the conclusion survives both cases, the decision is usually more robust.
What can change the real outcome?
Taxes, policy rules, employer terms, personal behavior, and financing costs can all move the final result away from the estimate.
