About Mortgage Refinance Calculator

This Mortgage Refinance Calculator helps you determine if refinancing your mortgage is a financially sound decision. Compare your current mortgage terms with a potential new loan to see monthly payment changes, total interest savings, and the critical break-even period. Whether you are considering refinancing to lower your rate, shorten your term, or access equity, this tool provides the analysis you need to make an informed decision.

What is Mortgage Refinancing?

Mortgage refinancing is the process of replacing your existing home loan with a new mortgage, typically to take advantage of better terms. The new loan pays off your original mortgage, and you begin making payments under the new agreement. Common reasons to refinance include:

Key Metrics Explained

Break-Even Point

The break-even point is the most important metric when evaluating a refinance. It represents the number of months until your cumulative monthly savings equal the total refinancing costs. If you plan to sell or move before reaching the break-even point, refinancing may cost you money rather than save it.

Break-Even Formula
\[\text{Break-Even (months)} = \frac{\text{Total Closing Costs} }{ \text{Monthly Payment Savings} }\]

Monthly Payment

Your monthly mortgage payment is calculated using the standard amortization formula:

Monthly Payment Formula
\[M = P \times \frac{r(1+r)^n}{(1+r)^n - 1}\]

Where:

Mortgage Points

Discount points (or "mortgage points") are upfront fees paid to the lender to reduce your interest rate. One point equals 1% of the loan amount. For example, on a $300,000 loan, one point costs $3,000. Points can make sense if:

Tip: As a rule of thumb, each point typically reduces your interest rate by 0.25%. Calculate whether the monthly savings will recover the point cost within your expected ownership period.

How to Use This Calculator

  1. Enter your current mortgage details: Input your remaining loan balance, current interest rate, and years left on your loan.
  2. Specify new loan terms: Enter the new interest rate offered and select your desired loan term (15, 20, 25, or 30 years).
  3. Add refinancing costs: Input estimated closing costs and any points you plan to pay. Closing costs typically range from 2-5% of the loan amount.
  4. Choose closing cost treatment: Decide whether to roll closing costs into the new loan (no out-of-pocket) or pay them upfront (lower total cost).
  5. Review results: Analyze the comparison showing payment changes, savings, break-even timeline, and recommendation.

Frequently Asked Questions

What is mortgage refinancing?

Mortgage refinancing is the process of replacing your existing mortgage with a new loan, typically to secure a lower interest rate, change the loan term, switch from an adjustable to fixed rate, or access home equity. The new loan pays off the original mortgage, and you begin making payments on the new terms.

What is a break-even point in refinancing?

The break-even point is the number of months it takes for your monthly savings from refinancing to equal the total closing costs paid. After the break-even point, you begin realizing actual savings. If you plan to sell or move before reaching the break-even point, refinancing may not be cost-effective.

What are mortgage points and should I pay them?

Mortgage points (also called discount points) are upfront fees paid to the lender to reduce your interest rate. One point equals 1% of the loan amount. Paying points makes sense if you plan to stay in the home long enough for the monthly savings to exceed the upfront cost.

Should I include closing costs in my new loan?

Including closing costs in your new loan (rolling them in) means no out-of-pocket expense at closing, but you will pay interest on those costs over the life of the loan. Paying closing costs upfront saves money long-term but requires available cash. The best choice depends on your cash reserves and how long you plan to keep the mortgage.

When is the best time to refinance?

Consider refinancing when interest rates drop 0.5-1% below your current rate, your credit score has improved significantly, you want to switch from adjustable to fixed rate, you need to change your loan term, or you plan to stay in the home past the break-even point.

What closing costs should I expect when refinancing?

Typical refinance closing costs range from 2-5% of the loan amount and may include: application fee, origination fee, appraisal fee, title search and insurance, credit report fee, recording fees, and prepaid items (taxes, insurance). Always get a detailed Loan Estimate from your lender before committing.
