Mortgage Refinance Calculator

Refinancing a mortgage is about the numbers. Refinancing a mortgage can be a money-saver for borrowers who can snag a lower rate, lower their monthly payments, shorten their loan term or ditch mortgage insurance premiums.

Before you shop around for lenders, crunch the numbers to make sure refinancing your existing home loan will save you money. Bankrate’s mortgage refinance calculator will give you an idea of how much you stand to save (or lose).

What is mortgage refinancing?

Mortgage refinancing is replacing your current home loan with a new loan. Just like any other loan, you apply for refinancing, which includes a thorough check of your credit, income, employment history and finances. A lender orders a home appraisal to assess the current market value of your home, too, and how much equity you have in it.

When you refinance, the borrowed money from your new loan pays off your existing loan. Most people refinance to lock in a lower interest rate and lower their monthly payment, or to shorten the term of their mortgage. You can also get a cash-out refinance, which allows you to borrow against the equity in your home, pulling some or all of the difference between what you still owe and its current value. Ideally, you’ll also get a lower rate in the process. The money you tap from your home’s equity can be used to consolidate higher-interest debt or to improve your home.

How much does it costs to refinance a mortgage?

While refinancing can save you money in the long run, it comes with upfront fees. Refinancing includes much of the same fees you paid when you first bought your home, such as:

  • Lender fees, including a mortgage application fee, loan origination charges and points
  • Third-party fees, such as the appraisal fee, document recording and a credit check
  • Title search/insurance fees
  • Escrow costs for property taxes and homeowners insurance
Your closing costs will vary depending on the new loan amount, your credit score and debt-to-income ratio, loan program and interest rate.

Shopping around for a lender who not only offers a competitive interest rate but also the lowest fees is worth your time and effort. Because refinancing can cost thousands of dollars, make sure refinancing has a tangible benefit to your finances and that you’ll stay in your home long enough to recoup the fees.

What is the break-even point on a mortgage refinance, and why does it matter?

A key consideration when deciding whether to refinance a mortgage is when you’ll break even on refinancing costs. The break-even point is calculated by adding up all refinancing closing costs and figuring out how many years it will take you to make your new, lower mortgage payment to recoup those costs. Refinancing makes more sense if you plan to stay in your home longer than the break-even point, otherwise, you could potentially lose money.

How long do you plan to stay in your home, and why is it important?

Before refinancing, you should first consider how long you plan to stay in your home. Refinancing if you plan to move in a few years won’t make financial sense just to lower your interest rate and monthly payment but not at least break even on closing costs. On the other hand, refinancing to a lower rate might save on cash in the first few years but another 30-year loan term means you’ll actually pay more, overall, in interest payments for the new mortgage.

What are the most common reasons to refinance a mortgage?

Homeowners refinance their mortgage for a variety of reasons. No matter what your motivation is for refinancing, the result should leave you better off financially. Here are a few common reasons why homeowners decide to refinance a mortgage:

  1. To lock in a lower interest rate and lower their monthly payments. Homeowners who have improved their credit score or lowered their debt-to-income ratio, for example, might be eligible for a better rate today if they refinance.
  2. To switch from an adjustable-rate mortgage, or ARM, to a fixed-rate loan. Borrowers who took out an ARM but plan to stay in their homes may want to refinance into a more stable, fixed-rate loan before the ARM resets to a variable rate and payments become unaffordable.
  3. To pull out cash from their home’s equity. A cash-out refinance lets you tap your home’s equity by replacing your existing mortgage with a new one for a larger loan amount, withdrawing the difference in cash.
  4. To remove a borrower from the mortgage. Divorce is another reason to refinance in order to get one spouse’s name off the loan. This might also apply if you bought a home with another relative or friend. The person who is refinancing the loan into his or her name will have to qualify for the new loan solely with their own income, credit and employment. Don’t forget that removing someone from a mortgage doesn’t remove them from the deed of the home, which may require filing a legal document called a quitclaim deed (check your state’s property laws for guidance).
  5. To get rid of FHA mortgage insurance. For borrowers with a loan insured by the Federal Housing Administration, known as FHA loans, refinancing into a conventional mortgage can eliminate annual mortgage premium payments once you’ve reached 20 percent equity in your home.

Refinancing next steps

If you’ve looked at the numbers and refinancing makes sense, then it’s time to shop around for a refinance lender. Check with your current mortgage servicer, as well as national banks, credit unions, online mortgage lenders and a possibly a mortgage broker to compare refinance rates and terms.
Make sure you get everything in writing, such as fees and interest rates. Lenders will send you a loan estimate that breaks down your new loan details and all fees. Loan estimates are great tools for comparison shopping to give you the clearest picture of which lender will help you meet your refinance goals.
