7 minute read
August 10, 2022


If you have a mortgage, and want a smaller payment, you might ask, “Should I refinance my mortgage?” 

A mortgage refinance calculator can help you answer that question. 

Mortgage calculators can help you figure out the math, but there’s more to refinance than just the numbers. 

What is mortgage refinancing?

Mortgage refinance is when a homeowner decides to switch their current mortgage for a new one with better terms, typically to reduce their monthly payment and long-term costs.  

Refinancing requires you to complete a new mortgage loan application, submit new supporting documents, and meet different eligibility requirements. 

Many homeowners find the mortgage refinance process more streamlined than their first mortgage because they understand the process better this time. 

Submit your refinance scenario

How does mortgage refinance work?

When you refinance your existing mortgage, the new mortgage loan you receive pays off your first home loan altogether. 

After that, you’ll continue to make monthly mortgage payments on your new loan until it is repaid or until you refinance it. You’ll still only have one monthly payment, it’s just on a new loan.

To estimate the amount of your new mortgage and help you decide whether you should refinance, take a few minutes to enter loan details into the mortgage refinance calculator below.

Is mortgage refinancing right for me?

The reasons homeowners choose to refinance their mortgage are personal and specific to their financial situation. 

But, there are common reasons why a homeowner might want to refinance their current mortgage. These include:

  • Better interest rates
  • Reduced monthly mortgage payment
  • Get a fixed-rate mortgage (and/or get rid of an adjustable-rate one)
  • Get rid of mortgage insurance
  • Cash-out refinance
  • Change loan providers

Get a better interest rate

Lower interest rates mean spending less each month on monthly payments and homeowners can potentially save thousands of dollars on their mortgage with a lower interest rate. 

If rates have dropped or your credit score has improved since your first mortgage process, you could be eligible for an interest rate better than the one you’re currently paying. 

Reducing the monthly mortgage payment

In addition to lower interest rates, you might be able to reduce your monthly mortgage payments by lengthening your mortgage term. 

For example, going from a 10-year amortization period to a 20-year amortization period could decrease your monthly payments while freeing up cash in your monthly budget. 

An extended amortization period plus a better interest rate could mean significantly smaller monthly mortgage payments.

Adjustable rate to a fixed-rate mortgage

With an adjustable-rate mortgage, the amount of money you pay each month can change, depending on the adjustment period. 

For some adjustable rate mortgages, homeowners get a new interest rate—based on the current market—each year. If rates drop, you can save money, but when rates increase, you can find yourself paying more than you want to. 

Switching to a fixed-rate mortgage allows homeowners to lock in a specific rate and pay only that rate for the lifetime of their loan—no matter what the markets do.

Eliminate mortgage insurance

If you’ve been paying into your mortgage for a while, you may have built up enough equity in your home to stop paying mortgage insurance. 

20% equity in your home is required to refinance your mortgage and stop paying mortgage insurance. 

Many lenders require mortgage insurance when a homeowner has less than 20% equity in the home. Eliminating mortgage insurance can put that money back in your wallet. 

Cash-out refinance

Cash-out refinance mortgages are popular refinance options for many homeowners who have built up some equity in their homes. 

By tapping into the equity, homeowners get a lump sum cash payment that they can use for any purpose they want. For example, many homeowners use money from cash-out refinance to consolidate loans, pay for education, add to retirement savings, or finance home upgrades or renovations.

It’s a good idea to estimate your new monthly mortgage payments by using a mortgage refinance calculator to ensure that your new monthly payments are something you can safely afford. 

Change loan providers

If you aren’t enjoying the level of service your current mortgage providers deliver, you might consider a mortgage refinance as a way to switch lenders. Alternately, some borrowers may decide to work with a bank rather than a private mortgage lender.

How much will it cost to refinance?

Because refinancing your current mortgage requires an entirely new application process, homeowners should budget for closing costs. 

While the amount you’ll pay will be specific to your mortgage details, such as your mortgage amount, credit score, personal finances, etc., many homeowners can expect to pay between $5,000 and $10,000 in mortgage refinancing closing costs. 

Common mortgage refinancing costs can include: 

  • Home appraisal fees
  • Lawyers fees
  • Title insurance
  • Land transfer tax 
  • Loan origination fees, among others

Many homeowners find that the short-term costs associated with mortgage refinance are worth the long-term benefit. 

Additionally, the IRS allows for some mortgage refinancing costs—such as mortgage interest—to be deducted when homeowners file their income taxes.
