What $300,000 of mortgage really costs

A $300,000 loan is squarely in the mainstream of American mortgages — near the typical loan on a median-priced U.S. home with 20% down. It's also where rate shopping pays real money: the spread between a 5% and 8% rate on this balance is $591 every month.

The full monthly bill is more than principal and interest. If this loan is 80% of the home's price ($375,000 home), national-average property tax (1.1%/yr) adds about $344/month and average insurance ($2,341/yr) another $195 — bringing the realistic total to roughly $2,435/month. Under the classic 28% housing ratio, that suggests around $104,359 of household income. Local taxes change this a lot — see the state-by-state comparison.

Frequently asked questions

How much is the monthly payment on a $300,000 mortgage?

At 6.5% on a 30-year fixed loan, principal and interest run $1,896.20 per month. With typical property taxes and insurance on top (assuming the loan is 80% of the home's price), the full monthly cost is roughly $2,435. On a 15-year term at the same rate the payment is $2,613.32. The table above shows every half-point from 5% to 8%.

How much income do I need for a $300,000 mortgage?

Using the standard 28% housing-ratio guideline and the full payment estimate above, you'd want roughly $104,359 of gross annual income ($8,697 per month). Less existing debt, a bigger down payment, or a lower rate all reduce that requirement — work your exact numbers in our home affordability calculator.

How much interest does a $300,000 mortgage cost over 30 years?

At 6.5%, total interest over a full 30-year schedule is about $382,633 — 128% of the amount borrowed. A 15-year term cuts that to about $170,398, and extra payments can remove years without changing the required payment.
