Michigan Mortgage Refinance Calculator

By SoFi Editors | Updated November 20, 2025

Refinancing your home loan can be a wise financial move if you want to lower your monthly payment or save on interest over the life of the loan. However, you should understand all the costs involved before committing to anything. When deciding how to refinance a mortgage, use a Michigan mortgage refinance calculator to estimate the costs and potential savings.

Key Points

•  Using a mortgage refinance calculator can help you determine the point at which you’ll break even, allowing you to see if the savings from refinancing will outweigh the costs.

•  Checking current mortgage rates is important for determining whether to refinance, as these factors can significantly impact potential savings.

•  Purchasing mortgage points can lower your interest rate and monthly payments, but you’ll need to do a careful cost-benefit analysis with a home refi calculator to see if it’s worth it.

•  Extending the loan term can reduce your monthly payments but increase the total interest paid over the life of the home loan, so always evaluate such a trade-off with a mortgage refi calculator before making this decision.

•  Improving your credit score can lead to a better interest rate and lower your monthly payments.

Calculator Definitions

•  Remaining loan balance: The remaining loan balance is the principal amount you still owe on your home loan, and it determines how soon you can refinance a mortgage.

•  Current/New interest rate: Interest is the percentage of the loan amount the lender charges. Refinancing with a lower interest rate can reduce your monthly payments and total interest costs.

•  Remaining/New loan term: The remaining loan term is the number of months left on your current mortgage. When refinancing, you can choose a shorter term that reduces the total interest paid or a longer term that lowers your monthly payments.

•  Points: Mortgage points allow you to reduce the interest rate by prepaying the interest at closing. Each point costs 1% of the loan amount and can lower the rate by .25%.

•  Other costs and fees: Refinancing involves origination fees, appraisal fees, and attorney fees, typically ranging from 2% to 5% of the loan amount. When estimating the total cost of refinancing, make sure you include these fees.

•  Monthly payment: In addition to the principal, your monthly mortgage payment includes the interest on the loan. To determine if refinancing is right for you, use a refi mortgage calculator to estimate these interest costs, and compare them with your current loan.

•  Total interest: The total interest is what you pay the lender over the life of the loan, excluding the principal. To determine if refinancing will save you money in the long term, compare the total interest on your current mortgage to the projected total interest of the refinance option you’re considering.
