1. What is the House Refinance Calculator?

This calculator helps determine your monthly mortgage payment when refinancing your home. It uses the standard mortgage payment formula that accounts for loan amount, interest rate (APR), and loan term.

2. How Does the Calculator Work?

The calculator uses the mortgage payment formula:

\[ PMT = P \times \frac{\frac{apr}{12} \times (1 + \frac{apr}{12})^n}{(1 + \frac{apr}{12})^n - 1} \]

Where:

\( PMT \) — Monthly payment
\( P \) — Loan principal amount
\( apr \) — Annual percentage rate (as decimal)
\( n \) — Total number of payments (months)

Explanation: The formula accounts for compound interest over the life of the loan, calculating the fixed monthly payment needed to pay off the loan completely by the end of the term.

3. Importance of Accurate Refinance Calculation

Details: Understanding your potential monthly payment is crucial when considering refinancing. It helps you determine if refinancing will save you money and fits within your budget.

4. Using the Calculator

Tips: Enter the new loan amount, APR (annual percentage rate including fees), and loan term in years. For accurate results, use the APR rather than just the interest rate as it reflects the true cost of borrowing.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between interest rate and APR?
A: The interest rate is the cost of borrowing the principal, while APR includes the interest rate plus other loan fees, reflecting the total cost of the loan.

Q2: How does loan term affect my payment?
A: Longer terms reduce monthly payments but increase total interest paid. Shorter terms have higher payments but lower total interest costs.

Q3: Should I include taxes and insurance in this calculation?
A: This calculator shows principal and interest only. Your actual payment may include property taxes and insurance if escrowed.

Q4: How accurate is this calculator?
A: It provides precise calculations based on the inputs, but actual loan offers may vary slightly due to rounding or specific lender practices.

Q5: When does refinancing make sense?
A: Typically when you can get a rate at least 0.5%-1% lower than your current rate, or when you need to change your loan term to better fit your financial situation.
