When looking for a feature-packed compact vehicle for daily commutes, the debate often comes down to choosing between a traditional petrol vehicle and a modern electric alternative. To understand the financial impact over the long run, here is a detailed 5-year Total Cost of Ownership (TCO) comparison between the Tata Punch EV (Adventure 40kWh) and the Hyundai Exter (SX AMT), assuming an annual running of 15,000 km (75,000 km over 5 years).
The Financial Breakdown

Note: Inflation factors account for Petrol at 5% p.a., Electricity at 4% p.a., Service & Tyres at 6% p.a., and Insurance at 5% p.a.
Key Takeaways from the Cost Analysis
1. Fuel vs. Electricity Savings
The Hyundai Exter petrol operating at a realistic 15 kmpl mileage accumulates a fuel bill of ₹5,10,000 over 75,000 km. In contrast, the Tata Punch EV, utilizing its 40kWh battery with a real-world range of 330 km, consumes roughly 10,000 units of electricity (including a 10% charging loss). At a Delhi residential rate of ₹8/unit, the 5-year energy bill comes out to exactly ₹80,000—representing a massive savings of ₹4,30,000 in fuel costs alone.
2. Maintenance and Running Expenses
EVs have fewer moving parts, which translates into lower maintenance outlays (₹25,000 for the Punch EV vs. ₹45,000 for the Exter). However, EV-specific tyres are slightly more expensive due to the higher torque and vehicle weight, costing around ₹7,000 per tyre compared to ₹6,000 for the petrol vehicle.
Excluding the initial vehicle purchase price, the standalone running cost for the Exter stands at ₹10.04 per km, whereas the Punch EV operates at a highly efficient ₹3.75 per km.
3. Charging Infrastructure Impacts
The charging ecosystem chosen directly influences overall expenditure and convenience:
Standard 3.2kW Home Charger: Charges from 10% to 100% in approximately 14.8 hours, keeping the 5-year energy bill at ₹80,000.
PDF
7.2kW AC Fast Charger: Reduces charging time significantly to 5.3 hours, but increases the 5-year expense to ₹1,10,000 due to additional fixed load infrastructure charges.
PDF
Public Charging Mix: Transitioning to a hybrid model—such as 70% home charging and 30% public DC fast charging (at ~₹25/unit)—will predictably elevate long-term electricity outlays.
PDF
The Solar Advantage: Integrating a 5-6kW residential solar setup brings variable electricity costs down to absolute zero, optimizing the lifetime savings of the EV.

Summary
Over a 5-year period covering 75,000 km, the Tata Punch EV proves to be significantly more economical than the Hyundai Exter Petrol, despite its higher initial on-road price. When accounting for realistic inflation parameters, the cumulative expenditure for the Hyundai Exter reaches ₹18.35 Lakh, while the Tata Punch EV settles at ₹15.04 Lakh. This delivers a net savings of approximately ₹3.31 Lakh in favor of the electric vehicle, driven primarily by its ultra-low running cost of ₹3.75/km compared to the petrol car's ₹10.04/km.
