1. What is a Refinance Mortgage Rates Calculator?

Definition: This calculator estimates your monthly mortgage payment when refinancing, based on loan amount, interest rate, and loan term.

Purpose: It helps homeowners evaluate potential savings when considering refinancing their mortgage.

2. How Does the Calculator Work?

The calculator uses the standard mortgage formula:

Where:

• \( M \) — Monthly payment (USD)
• \( P \) — Loan principal amount (USD)
• \( r \) — Monthly interest rate (annual rate ÷ 12)
• \( n \) — Number of payments (loan term in years × 12)

Explanation: The formula accounts for both principal and interest payments over the loan term.

3. Importance of Refinance Calculation

Details: Proper calculation helps determine if refinancing will lower your monthly payments, reduce total interest, or shorten your loan term.

4. Using the Calculator

Tips: Enter your current loan balance, the new interest rate you qualify for, and the desired loan term. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q4: What's a good refinance rate?

Q5: How often can I refinance?
