Down Payment Calculator
Punch in a home price and the percent you want to put down — or a set dollar amount — and see the cash needed and the loan that's left.
How it works
Give it a home price and a percentage and it multiplies the two. A $400,000 home at 20% down means $80,000 in cash and a $320,000 loan. The rest of your mortgage is built on that loan figure.
Already know the cash you've saved? Flip to dollar mode, type the amount, and it works out the percentage instead. $50,000 down on that same $400,000 home is 12.5%, which tells you where you stand against the 20% mark.
That 20% line matters because dropping below it usually triggers private mortgage insurance, an extra monthly charge until you build enough equity. Seeing the percentage up front helps you decide whether to stretch for a bigger down payment.
Frequently asked questions
How much should I put down on a house?
Twenty percent is the classic target because it dodges private mortgage insurance, but plenty of loans allow far less — some as low as 3%. More down means a smaller loan and lower monthly payments, weighed against keeping cash in reserve.
What is the loan amount?
It's the home price minus your down payment — the part you actually borrow. Put $80,000 down on a $400,000 home and you're financing $320,000, which is the figure your mortgage payment is calculated from.
Does a bigger down payment lower my monthly payment?
It does, on two fronts. A larger down payment shrinks the loan, and crossing 20% can drop mortgage insurance entirely. Both trim the monthly bill, though tying up more cash upfront has its own trade-offs.
