How Mortgage Payments Work

Mortgage payments consist of four main components:

  • Principal: Payment toward the original loan amount
  • Interest: Cost of borrowing the money
  • Taxes: Property taxes (escrowed monthly)
  • Insurance: Homeowner's insurance (escrowed monthly)
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]
M = Monthly payment P = Principal loan amount i = Monthly interest rate n = Number of payments

Amortization Explained

Amortization is the process of paying off a debt over time through regular payments. With each payment:

  • Early payments are mostly interest
  • Later payments are mostly principal
  • Equity builds slowly at first, then accelerates
Year 5 ~10% Equity
Year 10 ~20% Equity
Year 20 ~50% Equity

Mortgage Calculator FAQ

What is PMI and when is it required?

Private Mortgage Insurance (PMI) is required when your down payment is less than 20%. It protects the lender if you default. PMI typically costs 0.5% to 1% of the loan amount annually and can be removed once you reach 20% equity.

Should I choose a 15-year or 30-year mortgage?

15-year loans have higher monthly payments but lower interest rates and save thousands in interest. 30-year loans have lower payments, providing more budget flexibility. Consider your financial goals and ability to handle higher payments.

How much house can I afford?

Most lenders recommend spending no more than 28% of your gross monthly income on housing costs. The 28/36 rule suggests 28% for housing, 36% for total debt. Use our calculator to find payments within your budget.

What's included in closing costs?

Closing costs typically range from 2-5% of the home price and include loan origination fees, appraisal fees, title insurance, escrow payments, recording fees, and prepaid interest. Always budget for closing costs separately from your down payment.
