Quick Tool Overview

The Down Payment Calculator works in both directions: from a price and a percentage to the cash you need, or from the cash you have to the price it supports. It reports the loan, the loan-to-value ratio, the payment and whether mortgage insurance applies.

About the Down Payment Calculator

Work from either direction: enter a home price and a percentage to get the cash you need, or enter the cash you have and see the price it supports. Either way you get the loan amount, the loan-to-value ratio and the monthly payment that results.

Twenty percent is the number everyone quotes, and the reason is private mortgage insurance. Below that threshold most conventional lenders add a monthly premium that buys you nothing, and the calculator shows what it costs so you can weigh saving longer against buying sooner. It also shows closing costs, which are the expense first-time buyers most often forget: they sit on top of the down payment and typically run two to five percent of the price.

Conventional loans start around three percent, FHA at three and a half, and VA and USDA at zero for eligible borrowers. Twenty percent is not required, it is simply the point where mortgage insurance stops.
