Based on data compiled by Credible, mortgage rates remained unchanged since yesterday, with the exception of 20-year rates, which rose slightly.

  • 30-year fixed mortgage rates: 2.750%, unchanged
  • 20-year fixed mortgage rates: 2.500%, up from 2.375%, +0.125
  • 15-year fixed mortgage rates: 2.000%, unchanged
  • 10-year fixed mortgage rates: 2.000%, unchanged

Rates last updated on Sept. 17, 2021. These rates are based on the assumptions shown here. Actual rates may vary.

What this means: Mortgage interest rates have held at historic lows throughout 2021. But both Fannie Mae and Freddie Mac predict rates will increase in the final quarter of 2021. Though it’s likely those increases will be relatively modest, keep in mind that even a 0.100% difference in a mortgage rate could add up to thousands of dollars over the life of a loan. Homebuyers who act in September to lock in a near record-low rate stand to reap significant savings.

How does the Federal Reserve affect mortgage rates?

The Federal Reserve System — or "The Fed," as it’s commonly called — is the United States’ central bank. It’s tasked with taking steps to keep the economy safe, stable, and flexible. Consequently, the Fed controls the U.S. money supply and short-term interest rates, and sets the Fed funds rate, which is the rate that banks apply when borrowing from each other overnight. 

But the Fed doesn’t actually set mortgage rates. Rather, multiple things the Fed does influence mortgage rates. For example, while mortgage rates don’t mirror the Fed funds rate, they do tend to follow it. If that rate rises, mortgage rates typically rise in tandem.

The Fed also buys and sells mortgage-backed securities, or MBS — a package of similar loans that a major mortgage investor buys and then resells to investors in the bond market. When the Fed buys a lot of mortgage-backed securities, it creates demand in the market, and lenders can make money even if they offer lower mortgage rates. So rates tend to be lower when the Fed is doing a lot of buying. When the Fed buys fewer MBS, demand falls and rates will likely rise..

Current mortgage rates

Average mortgage rates dipped for all terms this week, with the week’s average for 30-year mortgages sitting at 2.750%, and at 1.975% for 10-year mortgages.

Current 30-year mortgage rates

The current interest rate for a 30-year fixed-rate mortgage is 2.750%. This is the same as yesterday. Thirty years is the most common repayment term for mortgages because 30-year mortgages typically give you a lower monthly payment. But they also typically come with higher interest rates, meaning you’ll ultimately pay more in interest over the life of the loan.

Current 20-year mortgage rates

The current interest rate for a 20-year fixed-rate mortgage is 2.500%. This is up from yesterday. Shortening your repayment term by just 10 years can mean you’ll get a lower interest rate — and pay less in total interest over the life of the loan.

Current 15-year mortgage rates

The current interest rate for a 15-year fixed-rate mortgage is 2.000%. This is the same as yesterday. Fifteen-year mortgages are the second most-common mortgage term. A 15-year mortgage may help you get a lower rate than a 30-year term — and pay less interest over the life of the loan — while keeping monthly payments manageable. 

Current 10-year mortgage rates

The current interest rate for a 10-year fixed-rate mortgage is 2.000%. This is the same as yesterday. Although less common than 30-year and 15-year mortgages, a 10-year fixed rate mortgage typically gives you lower interest rates and lifetime interest costs, but a higher monthly mortgage payment.

How Credible mortgage rates are calculated

Changing economic conditions, central bank policy decisions, investor sentiment, and other factors influence the movement of mortgage rates. Credible average mortgage rates and mortgage refinance rates are calculated based on information provided by partner lenders who pay compensation to Credible.

The rates assume a borrower has a 740 credit score and is borrowing a conventional loan for a single-family home that will be their primary residence. The rates also assume no (or very low) discount points and a down payment of 20%.

Credible mortgage rates will only give you an idea of current average rates. The rate you receive can vary based on a number of factors.

Fixed vs. adjustable-rate mortgages: How they affect interest costs

Mortgage interest rates can be fixed (meaning they remain the same for the life of your loan) or variable (the rate can change after an initial period). The type of mortgage you choose will affect your interest rate.

Interest rates for fixed-rate mortgages tend to be higher than the initial interest rate for adjustable rate mortgages, or ARMs. But they don’t change, so you’ll know at the beginning of your loan exactly how much interest you’ll pay over the life of your mortgage.

Initial interest rates for ARMs are typically lower than fixed-rate mortgages. But after the end of an introductory period, your interest rate will change — and it could increase significantly. Introductory periods can vary from several months to a year or a few years. After the introductory period, your interest rate will be based on an index your lender specifies. ARMs may or may not cap how much your interest rate can increase.

It’s common for homeowners with adjustable-rate mortgages to refinance into fixed-rate loans when their introductory period is about to end.
