Savings & Comparisons
EV vs Petrol Cost Calculator
Compare operational expenditure between electric and internal combustion vehicles.
Primary Metric: Net Savings with EV
Savings & Comparisons Deterministic Model v1.2
EV Break-Even Calculator
Calculate the exact distance and timeframe required to recover the EV purchase premium.
Price Premium & Fuel Differential
Calculate payback mileage and recovery horizon Break-Even Distance 54,545 km Approx. 3.6 years (43.6 months)
Initial Purchase Premium:
Operational Savings / km: ₹5.50 / km
Annual Running Savings: ₹82,500.00 / yr
After 54,545 km, all subsequent driving yields pure cumulative operational profit compared to the petrol vehicle.
Mathematical Formula & Physical Model
Divides the initial purchase price premium by the per-kilometer operational cost savings to determine the financial recovery point.
1
Purchase Premium = EV Purchase Price - Petrol Purchase Price 2
Operational Savings per km = Petrol Cost per km - EV Cost per km 3
Break-Even Distance (km) = Purchase Premium / Operational Savings per km 4
Break-Even Time (Years) = Break-Even Distance (km) / Annual Driving Distance (km) Worked Example
Reference Benchmark₹300,000 Upfront EV Premium Recovery
Comparing a ₹1,500,000 EV against a ₹1,200,000 petrol car with a ₹5.50/km operational savings advantage at 15,000 km annual commute.
EV Price ₹1,500,000
Petrol Price ₹1,200,000
EV Cost/km ₹1.20 / km
Petrol Cost/km ₹6.70 / km
Annual Distance 15,000 km
Frequently Asked Questions
What happens if the EV is priced lower or equal to the petrol car?
If government subsidies, state tax waivers, or segment pricing make the EV cheaper upfront, the break-even is immediate (Day 1), delivering pure savings from the first kilometer.
Does higher annual mileage speed up break-even?
Yes, because operational savings accumulate on every kilometer driven, commercial fleets and high-mileage commuters recover the purchase premium significantly faster.
