1. What is the Mortgage Payment Formula?

The mortgage payment formula calculates the fixed monthly payment required to fully amortize a loan over its term. This is the standard calculation used by banks and financial institutions.

2. How Does the Calculator Work?

The calculator uses the mortgage payment formula:

Where:

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

Explanation: The formula accounts for both principal repayment and interest charges over the life of the loan, calculating a fixed payment that remains the same throughout the loan term.

3. Importance of Mortgage Calculation

Details: Understanding your mortgage payment helps with budgeting, comparing loan offers, and making informed decisions about home affordability and loan terms.

4. Using the Calculator

Tips: Enter the loan amount in USD, 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: What's included in a typical mortgage payment?
A: This calculator shows principal and interest. Actual payments may include property taxes, insurance, and PMI if applicable.

Q2: How does interest rate affect payments?
A: Higher rates increase monthly payments significantly. A 1% rate increase on a $300,000 loan adds ~$175 to the monthly payment.

Q3: What's the benefit of a shorter loan term?
A: Shorter terms (15 vs 30 years) have higher payments but save thousands in interest over the loan life.

Q4: How much can I afford to borrow?
A: Lenders typically recommend housing costs ≤28% of gross income. Use this calculator to test different loan amounts.

Q5: Are there other types of mortgage calculations?
A: Yes, for adjustable-rate mortgages (ARMs) or interest-only loans, different calculations apply.
