Down Payment Calculator
Calculate the down payment you need as a dollar amount or percentage, plus the monthly payment and total loan cost on a home.
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.

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.
Is this down payment calculator free to use?
Yes, True Calculator's down payment calculator is completely free with no sign-up, no app install and no usage limits.
