How it works

Your mortgage payment is a fixed amount that pays down principal and interest over the loan term; property tax and insurance ride along in escrow. Early payments are mostly interest, which is why the lifetime interest figure can surprise people.

Frequently asked questions

Does this include PMI?

No. With less than 20% down, lenders usually add private mortgage insurance (PMI) until you reach 20% equity. Add it to the taxes/insurance line to see your true payment.

How much interest will I pay overall?

On the defaults — a $320,000 loan at 6.5% over 30 years — you repay well over $400,000, more than $100,000 of it interest. A shorter term cuts that sharply.
