Why Every EV Decision in India Needs a Calculator

Making the switch to an electric vehicle in India is more complex than just comparing sticker prices. First, India's electricity is slab-rated — meaning charging cost isn't a flat ₹7/unit for everyone. Adding an EV to your home can push your overall household consumption into a higher slab, significantly altering your real monthly savings. Our calculators account for this exact DISCOM-level nuance.

Second, EV depreciation varies dramatically by model. While a premium BYD Atto 3 might retain value remarkably well, some early-generation 2-wheelers lose up to 35% of their value in the first year alone. Understanding your specific EV's battery State of Health (SoH%) and market depreciation curve is crucial for both buyers and sellers.

Finally, financing an EV comes with unique advantages like Section 80EEB, which allows taxpayers to deduct up to ₹1.5 lakh on interest paid. This makes EV financing cheaper than most buyers realize, completely changing the break-even math compared to a petrol vehicle.

Frequently Asked Questions — EV Calculators India

Which EV calculator should I use first?
If you're buying a new EV: start with the Subsidy Calculator to find the actual on-road price, then the Loan EMI + 80EEB calculator to understand monthly cost. If evaluating a used EV: use the Battery Health & Resale Value calculator. If you drive for Ola/Uber/delivery: the Gig Worker Break-Even calculator gives you the number you need.
Are these calculators accurate for India?
All calculators use India-specific data — DISCOM slab rates, PM E-DRIVE subsidy amounts, Section 80EEB limits, and model-specific depreciation rates derived from Indian used EV market listings. Estimates for resale value are typically within 10–15% of actual sale prices for popular models with sufficient market data.
Do I need to sign up or pay anything?
No. All 6 calculators are completely free. No signup, no email, no account required. Everything runs in your browser — no data is uploaded to any server.
How often is the subsidy data updated?
We update the subsidy calculator when PM E-DRIVE or state subsidy policies change. The date of last update is shown on the subsidy calculator page.
What is Section 80EEB and who can claim it?
Section 80EEB allows individual taxpayers to claim a deduction of up to ₹1.5 lakh on interest paid on EV loans, under the old tax regime. It applies to loans sanctioned between April 1, 2019 and March 31, 2023 — but the deduction can be claimed until the loan is fully repaid. Salaried individuals using the old tax regime benefit most.
Why does home charging cost vary so much by state?
India's electricity tariff is slab-rated — different price per unit applies at different consumption levels. Adding an EV can push your household into a higher consumption slab, which changes the rate not just for EV charging but for all units. The actual cost impact depends on your DISCOM, your current monthly consumption, and your EV's battery size.
Which EV holds resale value best in India?
Based on available used EV market data, premium EVs like BYD Atto 3 (~10% first-year depreciation) and Kia EV6 (~12%) hold value best. Mid-range EVs like Tata Nexon EV depreciate at ~22% per year. 2-wheelers like Ola S1 Pro depreciate fastest (~35%), partly due to rapid new model launches.
Can I use these calculators on mobile?
Yes. All calculators are built mobile-first and work on any smartphone browser without any app download.
