Mortgage rates are a bit unsteady today — rates on roughly half of purchase terms have increased, and the other half have decreased. Thankfully, according to Zillow, the popular 30-year fixed mortgage rate is down by two basis points to 6.59%. The 15-year fixed rate has also declined by four basis points to 5.91%, and the 5/1 ARM rate has dropped by nine basis points to 7.15%.

Interest rates probably won't plummet anytime soon. They should stay relatively stagnant into 2025, with occasional increases or decreases.

Use our mortgage calculator

Use Yahoo Finance's free mortgage calculator to see how various interest rates and term lengths will impact your monthly mortgage payment. It also shows how the home price and down payment amount play into things.

Our calculator includes homeowners insurance and property taxes in your monthly payment estimate. You even have the option to enter costs for private mortgage insurance (PMI) and homeowners' association dues if those apply to you. These details result in a more accurate monthly payment estimate than if you simply calculated your mortgage principal and interest.

30-year fixed mortgage rates

There are two main advantages to a 30-year fixed mortgage: Your payments are lower, and your monthly payments are predictable.

A 30-year fixed-rate mortgage has relatively low monthly payments because you’re spreading your repayment out over a longer period of time than with, say, a 15-year mortgage. Your payments are predictable because, unlike with an adjustable-rate mortgage (ARM), your rate isn’t going to change from year to year. Most years, the only things that might affect your monthly payment are any changes to your homeowners insurance or property taxes.

The main disadvantage to 30-year fixed mortgage rates is mortgage interest — both in the short and long term.

A 30-year fixed term comes with a higher rate than a shorter fixed term, and it’s higher than the intro rate to a 30-year ARM. The higher your rate, the higher your monthly payment. You’ll also pay much more in interest over the life of your loan due to both the higher rate and the longer term.

15-year fixed mortgage rates

The pros and cons of 15-year fixed mortgage rates are basically swapped from the 30-year rates. Yes, your monthly payments will still be predictable, but another advantage is that shorter terms come with lower interest rates. Not to mention, you’ll pay off your mortgage 15 years sooner. So you’ll save potentially hundreds of thousands of dollars in interest over the course of your loan.

However, because you’re paying off the same amount in half the time, your monthly payments will be higher than if you choose a 30-year term.

Adjustable mortgage rates

Adjustable-rate mortgages lock in your rate for a predetermined amount of time, then change it periodically. For example, with a 5/1 ARM, your rate stays the same for the first five years and then goes up or down once per year for the remaining 25 years.

The main advantage is that the introductory rate is usually lower than what you’ll get with a 30-year fixed rate, so your monthly payments will be lower. (Current average rates don't reflect this, though — fixed rates are actually lower. Talk to your lender before deciding between a fixed or adjustable rate.)

With an ARM, you have no idea what mortgage rates will be like once the intro-rate period ends, so you risk your rate increasing later. This could ultimately end up costing more, and your monthly payments are unpredictable from year to year.

But if you plan to move before the intro-rate period is over, you could reap the benefits of a low rate without risking a rate increase down the road.

Are interest rates expected to go down?

Are mortgage rates dropping?

Mortgage rates have mostly been rising over the last two months. However, rates on some of the most popular terms have inched down today.

How do I get the lowest refinance rate?

In many ways, securing a low mortgage refinance rate is similar to when you bought your home. Try to improve your credit score and lower your debt-to-income ratio (DTI). Refinancing into a shorter term will also land you a lower rate, though your monthly mortgage payments will be higher.
