By SoFi Editors | Updated November 21, 2025

Refinancing your mortgage can be a powerful way of managing your finances more effectively, but it’s important to understand both the potential benefits and costs involved before making any decisions. A mortgage refinance calculator can help you understand how to refinance a mortgage and make an informed financial decision by providing estimates of your monthly savings, total interest paid, and your break-even point. With these results, you can then decide if refinancing aligns with your financial goals and long-term plans. A refinance calculator can also help you determine how soon you can refinance a mortgage after your initial financing, as this can impact your financial strategy and the effectiveness of refinancing.

•   Remaining loan balance: The remaining loan balance is the outstanding principal amount on your current home loan. Input the correct balance to help you determine how soon you can refinance a mortgage.

•   Current/New interest rate: Interest is a percentage of the loan amount charged by the lender for borrowing. A lower interest rate can lead to significant savings over the life of the loan.

•   Remaining/New loan term: The remaining loan term is the number of months you have left to pay off your existing home loan. You can decide whether your new loan term will be shorter or longer than your current loan, which will affect your monthly payments and total interest paid.

•   Points: Mortgage points, also known as discount points, are upfront fees paid to the lender to lower the interest rate. Each point typically costs 1% of the loan amount and can reduce your monthly payments by 0.25%.

•   Other costs and fees: Refinancing your mortgage typically comes with other costs and fees, including origination fees, appraisal fees, and attorney fees. These typically range from 2% to 5% of the new loan amount.

•   Monthly payment: Your monthly payment includes the principal and interest on your home loan. Using a refi calculator can help you estimate your new monthly payment based on the refinanced terms and compare it with your current payment.

•   Total interest: Total interest is the cost paid to the lender over the life of the home loan, excluding the principal. A mortgage calculator can help you compare total interest costs between your current and refinanced loans and determine potential savings.
