Investopedia’s Mortgage Calculator is based on a complex formula that factors in your mortgage principal (how much you are borrowing), the interest rate you’re paying and the duration of the loan to determine how much that monthly mortgage payment will be. It lets you try out different scenarios of how much you might borrow and what varying interest rates will do to the amount you’ll be asked to pay. Read below to understand what each of these terms mean.
This seemed to be the thinking a few years ago, and things didn’t turn out very well. When you borrow more than you can realistically pay, that’s a sub-prime mortgage. Banks sold a lot of those to people who assumed the housing market would keep rising like gangbusters. Their home values would go up, giving them nearly instant equity and they could refinance quickly at a lower rate or sell the home for a quick profit. Lenders sold these loan products because they were making the same bet, and interest rates are always higher on sub-prime loans. Even if some ended up in foreclosure, the lenders would still make a tidy profit. Unfortunately, it was a bad bet for almost everyone.
With an adjustable-rate mortgage or ARM, the interest rate—and therefore the amount of the monthly payment—can change. These loans start with a fixed rate for a pre-specified timeframe of 1, 3, 5, 7 or 10 years typically. After that time, the interest rate can change each year. What the rate changes to depend on the market rates and what is outlined in the mortgage agreement.
If you plan on staying put until the mortgage is paid off, a fixed-rate loan will give you stability. The interest rate is a little higher than an adjustable-rate mortgage (ARM). But it won’t go up like an ARM can. The only things that will change your house payment over time are property taxes and insurance rates, but those will change regardless of which type of loan you get.
A third option – usually reserved for affluent home buyers or those with irregular incomes – is an interest-only mortgage. As the name implies, this type of loan gives you the option to pay only interest for the first few years, and it’s attractive to first-time homeowners because of the low payments during their lower earning years. It may also be the right choice if you expect to own the home for a relatively short time and intend to sell before the bigger monthly payments begin.

Buying a home with a mortgage is probably the largest financial transaction you will enter into. Typically, a bank or mortgage lender will finance 80% of the price of the home, and you agree to pay it back – with interest – over a specific period. As you are comparing lenders, mortgage rates and options, it’s helpful to understand how interest accrues each month and is paid.
