How to compare mortgage rates

Mortgage rates affect what you'll pay each month for your home. But what are they? And how can you make sure you're getting a good one?

Numerica is here to help you feel confident as you plan your next move.

What is a mortgage rate?

A mortgage rate is the interest you pay each year on the money you borrow to buy or refinance a home. It has a big impact on your monthly payment and on how much you'll pay in total over the life of your loan.

Some mortgage rates stay the same for the full loan. Others can change after a certain amount of time.

Your rate depends on things like your credit, loan type, down payment, and what's happening in the economy.

At Numerica, we'll help you find a mortgage rate and loan that match your financial goals.

What affects your mortgage rate?

Your mortgage rate isn't random. It's shaped by a mix of national trends and personal factors.

Here's what plays a role:

  • The economy: Rates often rise when inflation is high or the economy is growing fast.
  • Your credit score: Higher scores usually qualify for lower rates.
  • Your loan type: Different loans (like FHA or VA) come with different rate structures.
  • Your down payment: A bigger down payment can lower your rate.
  • Loan length and structure: A 15-year loan usually has a lower rate than a 30-year loan.

How mortgage rates impact your monthly payment

Your interest rate directly affects your monthly mortgage bill. Even a small difference can mean paying more or saving thousands over time.

Here's a simple example:

Loan AmountInterest RateEstimated Monthly Payment (Principal + Interest only)
$300,0006.5%$1,896
$300,0007.5%$2,098

That 1% increase adds about $200 more each month, or over $70,000 more across a 30-year loan.

Fixed vs. variable mortgage rates

When you apply for a loan, you'll usually choose between:

Fixed-rate mortgage

  • Rate stays the same for the life of the loan.
  • Predictable monthly payments.
  • Great if you plan to stay long term.

Variable-rate mortgage

  • Also called ARMs (adjustable-rate mortgages).
  • Rate may change after an initial fixed period.
  • Often starts lower than fixed rates.

Which is better? It depends on how long you plan to stay in the home and how comfortable you are with potential changes in your monthly cost.

How to get the best mortgage rate for you

Everyone wants a low rate, but the lowest number isn't always the best fit. Here's how to work towards a strong rate and a loan that meets your goals. 

Build your credit

  • Pay bills on time.
  • Keep credit card balances low.
  • Avoid new loans or credit applications right before applying.

Compare loan types

Some loan programs (like FHA or VA) offer lower rates or smaller down payments for eligible buyers.

Consider a rate lock

A rate lock lets you secure a specific rate for a set period during your loan process. This can protect you if rates go up before closing.

Don't forget about closing costs

Sometimes a super-low rate comes with higher closing fees. Look at the full loan estimate, not just the rate.

Final thoughts: Focus on fit, not just the rate

A low mortgage rate can save you money, but the right loan can save you stress.

Your best option is one that balances monthly costs, long-term goals, and your life today.
