What is Mortgage Refinancing?

Mortgage refinancing involves replacing your existing home loan with a new one, typically to secure a lower interest rate, reduce monthly payments, or change the loan term. It can be a powerful financial tool, but it also comes with costs, such as closing costs and points, which need to be weighed against the potential savings.

Our Refinance Calculator helps you analyze these factors to make an informed decision about whether refinancing is right for you.

What the Refinance Calculator is Good For

  • Monthly Payment Reduction: See how much you can lower your monthly mortgage payments.
  • Total Savings Estimation: Calculate the overall savings over the life of the loan.
  • Break-Even Point: Determine how long it will take to recoup your refinancing costs.
  • Interest Rate Comparison: Evaluate the impact of a new, lower interest rate.
  • Loan Term Adjustment: Analyze the financial implications of changing your loan term.

Limitations of the Refinance Calculator

  • Assumes Fixed Rates: This calculator assumes fixed interest rates for both current and new loans.
  • Excludes Other Costs: Does not include potential costs like appraisal fees, title insurance, or escrow fees beyond specified closing costs and points.
  • Market Fluctuations: Interest rates can change rapidly, impacting the accuracy of future projections.
  • Credit Score Impact: Your actual new interest rate will depend on your credit score and financial situation.
  • Tax Implications: Does not account for potential tax deductions on mortgage interest or points.

Mortgage Payment Formula

The monthly mortgage payment (M) is calculated using the following formula:

M = P [ i(1 + i)n ] / [ (1 + i)n – 1]

Where:
  • P = Principal Loan Amount
  • i = Monthly Interest Rate (Annual Rate / 12 / 100)
  • n = Total Number of Payments (Loan Term in Years * 12)

Frequently Asked Questions

When is a good time to refinance a mortgage?

A good time to refinance is typically when interest rates are significantly lower than your current rate, or when your credit score has improved, allowing you to qualify for better terms. It can also be beneficial if you want to change your loan term (e.g., from 30 to 15 years) or convert an adjustable-rate mortgage to a fixed-rate one.

What are closing costs in refinancing?

Closing costs are fees paid at the closing of a refinance loan. They can include origination fees, appraisal fees, title insurance, attorney fees, and other charges. These costs typically range from 2% to 5% of the loan amount and can be rolled into the new loan or paid upfront.

What is a break-even point in refinancing?

The break-even point is the time it takes for the savings from your lower monthly payments to offset the costs of refinancing. For example, if refinancing costs $3,000 and saves you $100 per month, your break-even point is 30 months ($3,000 / $100).

Can I refinance if I have bad credit?

While it's more challenging, refinancing with bad credit is possible, especially if you have significant home equity. However, you may not qualify for the lowest interest rates. It's advisable to improve your credit score before applying for a refinance to get the best terms.

Should I choose a shorter or longer loan term when refinancing?

Choosing a shorter loan term (e.g., 15 years) typically results in higher monthly payments but significantly less interest paid over the life of the loan. A longer term (e.g., 30 years) offers lower monthly payments but more total interest. Your choice depends on your financial goals and cash flow needs.
