Home Mortgage Refinance Calculator

Refinancing a home mortgage can be a smart financial move if the conditions are right. With interest rates constantly changing, homeowners often wonder whether refinancing their mortgage will save them money in the long run. To make this process simpler, our Home Mortgage Refinance Calculator helps you quickly evaluate potential savings, estimate new monthly payments, and calculate how long it will take to break even after covering closing costs.

This tool is designed to give you clear insights into whether refinancing is worth it, so you can make informed financial decisions with confidence.


How the Refinance Calculator Works

The refinance calculator is built to compare your current mortgage payments with the payments under a new interest rate. It also considers closing costs and calculates your break-even period—the number of months it takes before the savings from refinancing outweigh the upfront expenses.

By entering details like your loan amount, current rate, new rate, loan term, and closing costs, the calculator shows:

  • Your current monthly payment
  • Your new monthly payment
  • The monthly savings you would gain
  • The break-even period in months

Step-by-Step Guide: How to Use the Refinance Calculator

Using the refinance calculator is straightforward. Here’s how:

  1. Enter Current Loan Amount ($):
    Input your remaining loan balance. For example, if you still owe $180,000, type this amount.
  2. Enter Current Interest Rate (%):
    Add the percentage interest rate you are currently paying, such as 6.5%.
  3. Enter New Interest Rate (%):
    Type the lower interest rate you are considering, e.g., 5.0%.
  4. Enter Remaining Loan Term (Years):
    Specify the number of years left on your mortgage, for example, 20 years.
  5. Enter Closing Costs ($):
    Input the estimated refinancing fees, like $4,000.
  6. Click “Calculate”:
    The calculator will display your current monthly payment, potential new payment, monthly savings, and the break-even period.
  7. Use “Reset” if Needed:

Example: Refinancing in Action

Let’s say you currently owe $200,000 on your mortgage with a 6% interest rate and 20 years remaining. You find a lender offering a 4.5% interest rate, and the closing costs are $5,000.

  • Current monthly payment: $1,432.86
  • New monthly payment: $1,265.30
  • Monthly savings: $167.56
  • Break-even period: 29.9 months (about 2.5 years)

In this example, if you plan to stay in your home for at least three more years, refinancing could save you thousands of dollars in the long term.

Tips for Refinancing Your Mortgage

  1. Compare Multiple Lenders: Don’t settle for the first offer; shop around.
  2. Watch Interest Rates: Even a 0.5% decrease can make a big difference.
  3. Factor in Closing Costs: High fees may cancel out potential savings.
  4. Consider Loan Term: Shorter terms may increase payments but save more on total interest.
  5. Think About Future Plans: If you plan to move soon, refinancing may not be worth it.

Frequently Asked Questions (FAQs)

1. What is mortgage refinancing?
Mortgage refinancing is replacing your current mortgage with a new one, usually to secure a lower interest rate, reduce monthly payments, or change loan terms.

2. When is the best time to refinance?
It’s usually best to refinance when interest rates drop significantly below your current rate or when you plan to stay in your home long enough to recoup closing costs.

3. What are closing costs in refinancing?
Closing costs are fees charged by lenders and third parties, such as appraisal, title search, and origination fees.

4. How does the refinance calculator help me?
It shows your new monthly payment, savings, and how long it takes to break even after covering closing costs.

5. What is the break-even point?
It’s the time required for your monthly savings to equal your closing costs. After this point, refinancing provides pure savings.

6. Can refinancing lower my monthly payment?
Yes, if you secure a lower interest rate or extend your loan term, your monthly payment will decrease.

7. Will refinancing affect my credit score?
Yes, a hard credit inquiry during the application can temporarily reduce your score, but the impact is usually small.

8. Can I refinance with bad credit?
It may be possible, but you might not get favorable rates. Improving your credit score can increase your chances.

9. Are there risks to refinancing?
Yes, risks include high closing costs, extending debt for longer, or not saving enough to justify the switch.

10. What loan term should I choose when refinancing?
It depends on your goals—shorter terms save on interest but increase payments, while longer terms reduce payments but increase total interest paid.

11. How much can I save by refinancing?
Savings depend on your loan balance, rate difference, loan term, and closing costs. The calculator helps estimate this.

12. Is refinancing worth it for small rate changes?
Even a 0.5% drop in rate can save thousands over time, depending on loan size and duration.

13. How do I estimate my closing costs?
Ask lenders for an itemized estimate or check past refinancing averages, usually between 2–5% of the loan amount.

14. Can I refinance multiple times?
Yes, but each refinancing comes with costs and should be weighed against potential savings.

15. Should I refinance if I plan to sell my house soon?
Probably not, since you may not stay long enough to reach the break-even point.

16. What documents do I need for refinancing?
Typically, proof of income, employment verification, tax returns, bank statements, and credit history.

17. Will refinancing change my total interest paid?
Yes, depending on your new rate and term. Lower rates usually reduce total interest, but extending the term can increase it.

18. Can I refinance into a shorter loan term?
Yes, refinancing into a 15-year mortgage, for example, often reduces total interest paid, though monthly payments may rise.

19. Do I need to pay property taxes and insurance again when refinancing?
Yes, property taxes and insurance remain part of your housing costs, even after refinancing.

20. How do I know if refinancing is right for me?
Use the refinance calculator, compare lender offers, and consider your financial goals and future plans.
