Start with the financed amount, not just the car price
For a car loan, the financed principal is the amount actually borrowed after your down payment. A larger down payment lowers the principal and therefore lowers both the EMI and the interest charged in the fixed-rate model.
The exact amount financed by a lender may differ from the vehicle price because registration, insurance, accessories, taxes, processing fees or other charges can be paid upfront or included in the financed amount depending on the product.
Worked example: ₹10 lakh financed at 9.5% for 5 years
For a financed amount of ₹10,00,000 at 9.5% over 60 months, the modeled EMI is about ₹21,002.
Estimated total interest is about ₹2,60,112 and estimated total repayment is about ₹12,60,112, excluding fees and other vehicle ownership costs.
Financed amount₹10,00,000
Monthly EMI≈ ₹21,002
Total interest≈ ₹2,60,112
Total repayment≈ ₹12,60,112
Compare down payment, rate and tenure separately
Changing several inputs at once can make it difficult to see what actually improved the repayment profile. Compare one factor at a time: first down payment, then rate, then tenure.
A shorter tenure generally raises the monthly EMI but reduces the period over which interest accrues. A lower financed amount reduces both the monthly burden and the total interest in the model.
