What a $400,000 mortgage costs per month

Principal and interest only, so you can see the effect of the rate cleanly. Property tax and insurance are added in the calculator above.

Rate is the single biggest lever on a $400,000 loan. Half a percent might sound small, but across 30 years it moves the payment and the total interest by a lot. Here is the monthly principal and interest at a range of rates:

Lower the payment

Three ways to bring it down

To reduce the monthly cost on a $400,000 mortgage, you have three main levers. A larger down payment shrinks the loan itself. A lower rate, from stronger credit or shopping lenders, cuts the interest. A longer term spreads the balance over more payments, though it raises total interest. Try each in the calculator and watch both the monthly figure and the total interest respond.
