The down payment calculator below, from The Finance Reveal, shows how much cash you would put down and how much you would need to borrow: enter the purchase price and your down payment percentage, and it splits the price into your deposit and the loan amount.

What a down payment is

A down payment is the portion of a purchase price you pay upfront in cash, with the rest covered by a loan. It applies most often to homes and cars. The larger your down payment, the smaller your loan, which usually means lower monthly payments and less total interest over the life of the borrowing.

How to use the result

Use it to test how different deposit sizes change the loan you would carry, then feed the loan amount into our mortgage calculator or auto loan calculator to see the monthly cost. For homes, a larger deposit can also affect mortgage insurance, as our guide to down payments and PMI explains.

Frequently asked questions

How much should I put down?

It depends on your goals and cash. A bigger deposit lowers your loan, payments, and total interest, but leaving yourself an emergency fund matters too. There is no single right figure, only the balance that fits your situation.

Does a bigger down payment lower my interest?

It lowers the total interest you pay because you borrow less, and on some loans it can also improve the rate or remove extra charges like mortgage insurance.

What counts toward a down payment?

Usually your own saved cash. Some programs allow gifts or assistance, but the calculator simply splits the price by the percentage you enter.
