Massachusetts Mortgage Refinance Calculator

By SoFi Editors | Updated December 2, 2025

Before deciding to refinance your home loan, you must understand the potential benefits and the costs. Use our Massachusetts mortgage refinance calculator to estimate your new monthly payment, total interest paid, and the break-even point — which determines when your savings will surpass the initial costs. Review this guide to better understand if refinancing makes sense for you.

Key Points

•  Our Massachusetts refinance calculator helps estimate monthly payments, total interest costs, and the break-even point, all key elements to making an informed refinancing decision.

•  A small reduction in your interest rate — even a quarter percentage point — can lead to significant savings over the life of the loan, making refinancing a potentially advantageous move.

•  Extending the loan term can lower monthly payments, but will likely increase total interest paid.

•  Refinancing costs, like origination, appraisal, and attorney fees, can range from 2% to 5% of the loan amount.




Calculator Definitions

•  Remaining loan balance: The remaining loan balance is what you owe on your existing mortgage. This affects how soon you can refinance a mortgage. In general, you need to have at least 20% equity in your home.

•  Current/New interest rate: Interest is the percentage of the total loan amount that the lender charges. The difference between your current and new interest rates will determine potential savings from refinancing.

•  Remaining/New loan term: The remaining loan term represents the amount of time over which you are expected to repay your mortgage after completing the refinancing process. A shorter term can save you a significant amount of money in interest payments over the life of the loan, but will also lead to an increase in your monthly payments.

•  Points: Points, or discount points, are optional upfront fees you pay a lender to lower your interest rate. Each point costs 1% of the total loan amount and reduces the interest rate by 0.25%.

•  Other costs and fees: Other costs associated with refinancing include origination, appraisal, and attorney fees. These expenses typically range from 2% to 5% of the new loan amount.

•  Monthly payment: Your monthly mortgage payment typically includes both principal and interest. A refinance mortgage calculator can help you compare your current monthly payment with the estimated payment after refinancing to potentially secure better terms. Lower monthly payments alone don’t indicate whether a mortgage refinance will save you money over the long term.

•  Total interest: Total interest is the cost you pay — excluding the principal — to the lender over the duration of the loan. The home refi calculator lets you compare the total interest you will pay on your current and proposed loans, helping you estimate potential savings.
