Abbreviations Explained

PMI (Private Mortgage Insurance): Insurance required by lenders when down payment is less than 20% of home value. Protects the lender if you default.

APR (Annual Percentage Rate): The yearly cost of the mortgage including interest rate and fees, expressed as a percentage.

Principal: The original loan amount borrowed to purchase the home, excluding interest.

Interest: The cost of borrowing money from the lender, calculated based on the loan amount and interest rate.

Amortization: The process of paying off the loan through regular payments over time, with each payment covering both principal and interest.

Escrow: An account where funds for property taxes and insurance are held and paid by the lender on your behalf.

How the Calculation Works

This calculator uses the standard mortgage payment formula:

M = P × [r(1 + r)^n] / [(1 + r)^n - 1]

Where:

  • M = Monthly payment
  • P = Principal loan amount (home price - down payment)
  • r = Monthly interest rate (annual rate ÷ 12)
  • n = Total number of payments (loan term in years × 12)

Example: $300,000 loan at 6.5% for 30 years:
• P = $300,000
• r = 0.065 ÷ 12 = 0.00542
• n = 30 × 12 = 360 payments
• Monthly payment = $1,896
• Total interest over 30 years = $382,633

Understanding Mortgages

A mortgage is a loan used to purchase real estate, where the property serves as collateral. Key factors that determine your monthly payment:

  • Home Price: The purchase price of the property you're buying.
  • Down Payment: The upfront amount you pay, typically 3-20% of the home price. A larger down payment reduces your loan amount and may eliminate PMI.
  • Interest Rate: The cost of borrowing, influenced by credit score, market conditions, and loan type.
  • Loan Term: Most common are 15-year and 30-year mortgages. Shorter terms mean higher monthly payments but less total interest.

Remember: Your total monthly housing cost includes property taxes, homeowners insurance, and potentially HOA fees, which aren't included in this calculator.
