Down payment

$80,000

20.0% of home price

Loan amount

$320,000

Total cost

$808,142

Loan payments plus down payment

Monthly payment

$2,022.62

A larger down payment lowers your monthly payment and total interest, and can also remove the need for mortgage insurance.

How it works

Loan amount = price × (1 − down%). Payment uses the amortising formula; PMI added when down payment < 20%.

Example: $300,000 home, 20% down → $60,000 down, $240,000 loan, no PMI.

When to Use This Calculator

Use the down payment calculator when you are saving for a home and want to know what the upfront amount buys you. In India, a 20% down payment is the common expectation for home loans, and this tool works in both directions — it computes the down payment amount from a percentage of the property price, or the percentage a given lump sum covers. Enter the property price, the down payment you can manage and the loan rate and tenure to see the EMI, total interest and total loan cost that follow. First-time buyers saving in fixed deposits and mutual funds use it to set a savings target, and buyers with an unexpected windfall can check how a bigger down payment shrinks the loan and the interest. It is the starting point of any home-buying plan.

How to Use This Calculator

  1. Step 1: Enter the home price in the home price field — for an under-construction flat, use the agreement value.
  2. Step 2: Choose whether to enter the down payment as a rupee amount or as a percentage of the price.
  3. Step 3: Set the interest rate and loan term in years for the remaining amount.
  4. Step 4: Read the down payment, loan amount, monthly payment and total cost including interest over the full term.

Worked Example

You are buying a home for ₹80,00,000. With a 20% down payment, you pay ₹16,00,000 upfront and finance ₹64,00,000. At 8.5% for 20 years, the monthly payment is about ₹55,541, and the total cost — all EMIs plus the down payment — is about ₹1.49 crore. Raise the down payment to 30% and the loan drops to ₹56,00,000, lowering both the EMI and the interest paid over the term.

Tips and Common Mistakes

  • •Tip 1: RBI's loan-to-value guidelines cap financing at 90% for loans up to ₹30 lakh, 80% between ₹30 and 75 lakh and 75% above ₹75 lakh — the minimum down payment follows directly.
  • •Tip 2: Budget separately for stamp duty and registration, usually 5-8% of the property value depending on the state, since they are not covered by the loan.
  • •Tip 3: A larger down payment also shrinks the base on which lenders compute processing fees.
  • ✗Mistake 1: Entering a percentage when the field expects an amount — the two modes give very different down payments.
  • ✗Mistake 2: Planning only the down payment and ignoring registration, stamp duty, GST on under-construction flats and brokerage.

Frequently Asked Questions

How much should I put down on a house?

A 20% down payment avoids private mortgage insurance (PMI) and lowers monthly costs, but many programs accept 3–5% down. Use this calculator to see how each amount affects your loan and payment.

What is the minimum down payment for a conventional loan?

Most conventional loans allow as little as 3–5% down. FHA loans go as low as 3.5% and VA and USDA loans can be zero down for eligible borrowers.

How does a larger down payment save me money?

A bigger down payment means a smaller loan, so you pay less interest over the life of the mortgage, and at 20% you also eliminate PMI, a cost that typically runs 0.5%–1.5% of the loan per year.
