About this calculator
A down payment calculator turns a home price and a down payment percentage into the cash you need up front and the loan you must finance. It also flags whether you are likely to owe private mortgage insurance (PMI), which usually applies when the down payment is below 20%.
Frequently asked questions
How much down payment do I need?
It depends on the loan, but 20% avoids mortgage insurance on a conventional loan, while many programs allow 3–5%. On a 350,000 home, 20% is 70,000 down and 280,000 financed.
What is PMI and when do I pay it?
Private mortgage insurance protects the lender when your down payment is under 20%. It is an added monthly cost that usually falls away once you build 20% equity, so a bigger down payment can remove it entirely.
