Your mortgage rate plays a large role in how much your monthly payment will be. Use this mortgage calculator to see how your mortgage amount, rate, and term length will impact your monthly payments:

A mortgage interest rate is a fee for borrowing money from your lender, expressed as a percentage. You can choose from two types of rates: fixed or adjustable.

A fixed-rate mortgage locks in your rate for the entire life of your loan. For example, if you get a 30-year mortgage with a 6% interest rate, your rate will stay at 6% for the entire 30 years unless you refinance or sell.

An adjustable-rate mortgage locks in your rate for a predetermined amount of time and then changes it periodically. Let’s say you get a 7/1 ARM with an introductory rate of 6%. Your rate would be 6% for the first seven years, then the rate would increase or decrease once per year for the last 23 years of your term. Whether your rate goes up or down depends on several factors, such as the economy and housing market.

At the beginning of your mortgage term, most of your monthly payment goes toward interest. Your monthly payment toward mortgage principal and interest stays the same throughout the years — however, less and less of your payment goes toward interest, and more goes toward the mortgage principal or the amount you originally borrowed.

A 30-year fixed-rate mortgage is a good choice if you want a lower mortgage payment and the predictability that comes with having a fixed rate. Just know that your rate will be higher than if you choose a shorter term, and you will pay significantly more in interest over the years.

You might like a 15-year fixed-rate mortgage if you want to pay off your home loan quickly and save money on interest. These shorter terms come with lower interest rates, and since you’re cutting your repayment time in half, you’ll save a lot in interest in the long run. But you’ll need to be sure you can comfortably afford the higher monthly payments that come with 15-year terms.

Typically, an adjustable-rate mortgage could be good if you plan to sell before the introductory rate period ends. Adjustable rates usually start lower than fixed rates, then your rate will change after a predetermined amount of time. However, 5/1 and 7/1 ARM rates have similar to (or even higher than) 30-year fixed rates recently. Before getting an ARM just for a lower rate, compare your rate options from term to term and lender to lender.

Yes, for now. Mortgage rates have remained level or decreased over the last eight weeks. The 30-year and 15-year fixed rates are still just higher than they were this time last year.

Mortgage interest rates will probably stay relatively stable for the rest of the year. The latest Fannie Mae and Mortgage Bankers Association (MBA) forecasts predict that mortgage rates will stay at or just above 6% even through 2026.

According to Freddie Mac, the national average 30-year mortgage rate is down to 6.35% for the week, and the average 15-year mortgage rate also slipped lower to 5.50%.

According to its August forecast, the MBA expects the 30-year mortgage rate to be 6.6% by the end of the year and near 6.5% throughout 2026. Fannie Mae puts the 30-year rate at 6.5% by the end of the year and near 6.1% by the end of 2026.

Mortgage rates will probably be very close to where they are now, according to most industry forecasts, if not slightly lower.
