- Input any fixed bank processing fees to get the complete total cost of ownership.
Car Loan EMI Formula Explained
Car loan calculations use the reducing balance EMI formula on the funded loan amount: Loan Amount (P) = On-Road Price - Down Payment Monthly EMI = [P × r × (1 + r)^n] ÷ [(1 + r)^n - 1] Where: • P = Financed vehicle amount • r = Monthly interest rate (Annual Rate ÷ 12 ÷ 100) • n = Total tenure in months Total Vehicle Cost = Down Payment + (EMI × n) + Processing Fees.

Auto Finance Tips
- ✓Aim for a down payment of at least 20% to prevent "negative equity" (owing more on the loan than the depreciated market value of the car).
- ✓Follow the 20/4/10 budgeting rule: 20% down payment, loan tenure no longer than 4 years, and total auto expenses (EMI + insurance + fuel) under 10% of gross monthly income.
- ✓Check if your bank offers 100% on-road funding versus ex-showroom funding only (RTO and insurance require separate funding).
- ✓Negotiate dealer quotes with pre-approved car loan interest rate offers from your primary salary bank.
- ✓Consider electric vehicle (EV) loans: select banks provide 0.5% interest concessions on green auto loans.
Costly Mistakes to Avoid
- ✗Taking a 7-year car loan to lower the EMI, resulting in interest costs that exceed 40% of the vehicle’s original value.
- ✗Calculating EMI on ex-showroom price instead of the full on-road price (which includes road tax, FASTag, insurance, and accessories).
- ✗Buying expensive dealer add-ons (extended warranties and basic accessories) rolled into the loan principal.
- ✗Failing to compare dealer-arranged financing with public sector bank rates (SBI, Bank of Baroda).
