1. What is a 30-Year Mortgage?

A 30-year mortgage is the most common home loan term in the United States, offering fixed monthly payments over 360 months. While it results in more total interest paid compared to shorter terms, it provides lower monthly payments, making homeownership more accessible.

2. How Does the Calculator Work?

The calculator uses the standard mortgage payment formula:

Where:

• \( P \) — Principal loan amount (USD)
• \( r \) — Monthly interest rate (annual rate ÷ 12)
• 360 — Total number of monthly payments (30 years × 12)
• \( PMT \) — Monthly mortgage payment (USD)

Explanation: The formula accounts for compound interest over the loan term, calculating the fixed payment needed to fully amortize the loan.

3. Importance of Mortgage Calculation

Details: Accurate mortgage calculations help borrowers understand their long-term financial commitment, compare loan offers, and budget effectively for homeownership.

4. Using the Calculator

Tips: Enter the principal amount in USD and annual interest rate in percentage (e.g., 6.5 for 6.5%). Typical rates are 6-7% in USA, 8.40-8.45% in India.
