Refinancing House Calculator
What Is a Refinancing House Calculator?
A refinancing house calculator is an online tool that helps you estimate the costs and benefits of refinancing your home loan. It calculates:
- Monthly Payment: The amount you’ll pay every month.
- Total Payment: The overall amount you’ll repay by the end of the loan term.
- Total Interest: The portion of your payment that goes toward interest.
This calculator saves you from doing complicated formulas and instantly shows how changes in interest rate or loan term affect your finances.
How to Use the Refinancing House Calculator
Using our calculator is quick and easy. Just follow these steps:
- Enter Loan Amount
Type in the total loan balance you want to refinance. For example, if your current mortgage balance is $250,000, enter 250000. - Input Interest Rate (%)
Enter the new annual interest rate offered by your lender. For example, if you’re offered 5.5%, type 5.5. - Choose Loan Term (Years)
Select the number of years you want for repayment (e.g., 15, 20, or 30 years). - Click “Calculate”
The calculator will instantly show your monthly payment, total payment, and interest paid. - Compare Options
Try different scenarios with different rates and terms to see which refinancing plan saves you the most.
Example Calculation
Let’s walk through an example:
- Loan Amount: $200,000
- Interest Rate: 5%
- Term: 30 years
Results:
- Monthly Payment: $1,073.64
- Total Payment: $386,511.57
- Total Interest: $186,511.57
Now, let’s change the rate to 4% while keeping the same loan amount and term.
New Results:
- Monthly Payment: $954.83
- Total Payment: $343,739.01
- Total Interest: $143,739.01
That’s a savings of over $42,000 in interest—just by lowering the interest rate by 1%.
