Understanding Mortgage

Understanding mortgages

A mortgage is a loan used to buy a home. You repay it in monthly installments (principal and interest). In the USA, 30-year and 15-year fixed-rate mortgages are common. Our mortgage calculators help you see monthly payment, payoff time, affordability, refinance savings, and PMI.

Down payment and PMI

A down payment of 20% or more often avoids private mortgage insurance (PMI) in the USA. Smaller down payments may require PMI until you reach 20% equity. Use our down payment calculator to see how much you need and our PMI calculator to estimate PMI cost. Refinancing can make sense when rates drop or when you want to shorten the term.
