Car Loan EMI
The instalment is the easy part. This page also shows the effective rate after fees, and the uncomfortable chart hiding inside every long car loan — the years when the car is worth less than what you still owe on it.
Price the loan reducing balance · fees priced in
Car worth = the insurer's IDV: ex-showroom price less the IRDAI depreciation slab for the car's age (5% up to 6 months, 15% to 1 year, 20% to 2 years, 30% to 3, 40% to 4, 50% to 5; beyond 5 years it is negotiated — shown at 10%/year). Rows in red are negative-equity years: a total-loss claim pays the IDV, not your loan balance.
§1The formula — and the fee
A car loan amortises like any EMI loan — interest on the reducing balance, the same formula as a home loan:
Stretching the same loan to 7 years drops the EMI to about ₹15,568 — and lifts the interest to ₹3.48 lakh, a ₹1.05 lakh penalty for the smaller instalment. Car loans reward short tenures.
§2Negative equity — the part nobody shows you
A car loses value faster than a young loan loses balance. Insurers value a car by its IDV — the ex-showroom price less a depreciation slab fixed by IRDAI for the car's age:
So a ₹10.5 lakh ex-showroom car is insured for ₹8.4 lakh once it is a year old and ₹7.35 lakh in its second year — while an 80%-funded, 7-year loan on the ₹12 lakh on-road price still owes more than ₹8.9 lakh after year one. RTO and first-year insurance, which the loan funded, are gone the moment the car is registered. The table above prints both curves side by side.
Why it matters: if the car is stolen or totalled, insurance pays the IDV, not your loan balance. Underwater years mean you'd keep paying EMIs on a car that no longer exists. If your combination shows red rows, either raise the down payment, shorten the tenure, or add a return-to-invoice / GAP cover rider for those years — it's cheap.
§3Fixed vs floating — what RBI's rulebook says
Most Indian car loans are fixed — one rate, one EMI, start to finish. Floating car loans exist too (banks must peg them to an external benchmark, usually the repo rate, resetting at least quarterly under RBI's October 2019 external-benchmark framework). The choice is not just about rate direction — RBI attaches different rights to each:
The specific rules, by document:
RBI's (Pre-payment Charges on Loans) Directions, 2025 (issued 2 July 2025) bar every regulated lender — banks and NBFCs — from charging prepayment or foreclosure fees on floating-rate loans to individuals for non-business purposes, for loans sanctioned or renewed on or after 1 January 2026: part or full prepayment, any source of funds, no lock-in, no minimum amount. Bank customers had this since a 2014 circular; the 2025 Directions extend it to NBFCs and remove the loopholes. A fixed-rate car loan sits outside this protection entirely.
RBI's Reset of Floating Interest Rate on EMI based Personal Loans circular applies to consumer credit, and RBI's own FAQ confirms auto loans to individuals are included (non-commercial use). On a floating car loan, at every reset the lender must let you choose: raise the EMI or stretch the tenure (or both), prepay part or all of the loan, or switch to a fixed rate (per the lender's board policy, which must state how many switches you get). They must also show you the impact of each reset and send quarterly statements of principal and interest recovered. Silence is consent — the default is usually a longer tenure, so answer the reset letter.
For every retail loan sanctioned from 1 October 2024, the lender must hand you a standardised KFS stating the all-in APR (the number this page computes), the rate type — fixed, floating or hybrid — and every charge. Anything not in the KFS cannot be levied later without your explicit consent. If the desk quote and the KFS APR differ, the KFS wins — read it before signing, it's one page by design.

§4The gotchas
“7.99%” at the showroom desk is usually a flat rate — interest on the full amount for the full tenure, ignoring repayments. On a 5-year loan that's roughly 14–15% reducing. Banks quote reducing; dealers often quote flat plus collect a commission from the financier. Always ask “flat or reducing?” and compare EMIs, not rates.
On-road price = ex-showroom + RTO (8–15% by state and engine size) + insurance + accessories. Most “100% funding” offers fund 100% of ex-showroom — you still bring ₹1–2 lakh for the rest. Genuine on-road funding exists but at higher rates and stricter profiles. Budget from the on-road number; the field above starts there deliberately.
The RBI prepayment-fee ban (§3) protects floating-rate borrowers; on the typical fixed-rate car loan banks charge 3–6% of the outstanding to foreclose, often with a 6–12 month lock-in (a few, like SBI, waive it). If you expect to prepay — bonus, sale, upgrade — either pick a floating loan for the free exit, or get the foreclosure grid from the KFS before signing, not after.
Showroom insurance quotes run 20–40% above online quotes for identical cover, and “mandatory” accessory packs and extended warranties get quietly rolled into the loan — you then pay interest on floor mats for five years. Insurance is your choice of insurer by law; finance only the car.
Old, boring, effective: at least 20% down, no more than 4 years, and all car costs (EMI + fuel + insurance) under 10–15% of take-home. If the numbers only work at 7–8 years, the car is too expensive — the calculator will show you the red rows to prove it.
