Quick answer

Every rupee paid upfront is a rupee you don't pay interest on. On an ₹80,000 purchase at 12% for 12 months, a 20% down payment of ₹16,000 cuts the loan to ₹64,000, the EMI to ₹5,686 and interest to ₹4,236. That saves ₹1,059 compared with zero down payment.

How to use this calculator

Enter the on-road or final price.
Enter the down payment as a percentage of the price.
Add the loan rate and tenure from the dealer or bank.

Formula

Loan = price × (1 − down payment %)

EMI = loan × r × (1 + r)^n ÷ ((1 + r)^n − 1), with r = yearly rate ÷ 12 ÷ 100

Interest saved = interest at zero down − interest with your down payment

Dealer and bank offers differ. Ask for the full loan schedule before you sign.

Frequently asked questions

How much down payment is good?

20% or more keeps EMIs and interest low. Only pay more if you still keep an emergency fund.

Is zero down payment a good deal?

It is convenient, but you pay interest on the full price and often a higher rate or extra fees.

Does a down payment reduce processing fees?

Processing fees are usually a percentage of the loan, so a smaller loan means a smaller fee.
