How to Use This Calculator

To use this calculator effectively:

Enter your current loan balance in the "Current Loan Balance" field.

Enter the interest rate you're considering for your refinanced loan in the "Refinance Interest Rate" field.

The calculator will display your monthly payment for both your current loan and the refinanced loan, as well as the total interest paid over the life of the loan for each option.

Formula Used

The calculator uses the standard mortgage payment formula to calculate your monthly payments:

Monthly Payment = P * (r(1+r)^n) / ((1+r)^n - 1)

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years multiplied by 12)

The total interest paid is calculated by subtracting the principal loan amount from the total amount paid over the life of the loan.

Worked Example

Let's say you have a current loan with:

Loan balance: $200,000
Current interest rate: 6%
Remaining loan term: 5 years

You're considering refinancing to a 15-year term at 4%.

Using the calculator:

Enter $200,000 as the current loan balance.
Enter 6% as the current interest rate.
Enter 5 as the remaining loan term.
Enter 4% as the refinance interest rate.
Select 15 as the refinance term.
Click "Calculate".

The calculator will show you that your current monthly payment is approximately $3,865, while your refinance monthly payment would be about $1,520. Over the 15-year term, you would save about $12,000 in interest payments by refinancing.

FAQ

What is a 15-year refinancing?

A 15-year refinancing is a process where you replace your current mortgage with a new loan that has a 15-year repayment term. This typically results in lower monthly payments compared to a 30-year mortgage, but you'll pay more in total interest over the life of the loan.

How much can I save by refinancing to 15 years?

The amount you can save depends on your current interest rate, the new interest rate you qualify for, and the remaining term of your current loan. Generally, refinancing to 15 years can save you 20-30% in total interest payments compared to extending your current loan.

What are the benefits of a 15-year refinancing?

The main benefits of a 15-year refinancing include lower monthly payments, potential tax savings, and the ability to pay off your home sooner. However, you'll pay more in total interest over the life of the loan.

What are the risks of refinancing?

The main risks of refinancing include paying more in total interest, potential fees and closing costs, and the possibility of not qualifying for the new loan terms. It's important to carefully compare the costs and benefits before deciding to refinance.
