Key Points

•  A Missouri mortgage refinance calculator helps estimate potential savings and costs, comparing your current loan to a potential new one.

•  The break-even point is when the savings from refinancing will outweigh the associated costs.

•  Current market conditions, including mortgage rates, significantly influence the benefits of refinancing your existing mortgage.

•  Paying mortgage points can reduce your interest rate and monthly payments, but it requires careful consideration of upfront costs versus long-term savings.

•  Extending the loan term can lower monthly payments but increases the total interest paid over the life of the loan, so it’s important to weigh the trade-offs.

Calculator Definitions

•  Remaining loan balance: The remaining loan balance is the principal amount you still owe on your home loan.

•  Current/New interest rate: Interest is the cost of borrowing money, expressed as a percentage of the loan amount. The difference between your current interest rate and a potential new one, even a slight one, can significantly impact both your monthly payments and your overall savings over the duration of the loan.

•  Remaining/New loan term: The remaining loan term is the number of months left on your current mortgage. The new loan term is the total repayment period for the new loan. Shorter terms mean higher monthly payments but lower total interest costs.

•  Points: Mortgage points are optional upfront fees paid to reduce your interest rate. Each point costs 1% of the loan amount and can lower the rate by about 0.25%.

•  Other costs and fees: Refinancing costs include lender, appraisal, and attorney fees, typically ranging from 2% to 5% of the loan amount.

•  Monthly payment: Your monthly payment includes the principal and interest on your mortgage. A refinance calculator can estimate your new monthly payment and help you compare it with your current one. Keep in mind that lower monthly payments alone don’t indicate whether a refinance will save you money over the long term.

•  Total interest: Total interest is the cost you pay to the lender over the life of the mortgage. Comparing the total interest of your current and potential refinance loans helps determine the financial benefits.
