1. What is the Loan Payment Formula?

The loan payment formula calculates the fixed monthly payment required to fully amortize a loan over its term. This is essential for understanding mortgage refinancing options and comparing loan offers.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

Where:

• \( PMT \) — Monthly payment amount
• \( P \) — Principal loan amount
• \( r \) — Monthly interest rate (annual rate ÷ 12)
• \( n \) — Total number of payments (loan term in years × 12)

Explanation: The formula accounts for both principal repayment and interest charges, with more interest paid early in the loan term and more principal paid later.

3. Importance of Loan Payment Calculation

Details: Accurate payment calculation helps borrowers understand affordability, compare refinancing options, and plan their long-term finances when considering mortgage refinancing.

4. Using the Calculator

Tips: Enter the loan amount in dollars, annual interest rate as a percentage (e.g., 3.5 for 3.5%), and loan term in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How does refinancing affect my monthly payments?
A: Refinancing at a lower rate reduces monthly payments, while extending the term can also lower payments but increase total interest paid.

Q2: What costs aren't included in this calculation?
A: This calculates principal and interest only. Real payments may include property taxes, insurance, and PMI if applicable.

Q3: How often should I consider refinancing?
A: Consider refinancing when rates drop significantly (typically 0.5-1% below your current rate) or your credit score improves substantially.

Q4: What's the break-even point for refinancing?
A: Divide closing costs by monthly savings to determine how many months until you recoup refinancing costs.

Q5: Are there prepayment penalties?
A: Some loans have penalties for early payoff. Check your loan terms before refinancing.
