Buying a home is one of the biggest financial decisions you'll ever make. Understanding your mortgage payment is crucial to budgeting wisely and avoiding surprises.
What Is a Mortgage Payment?
A mortgage payment typically consists of four components, often called PITI:
- Principal: The loan amount you borrowed
- Interest: The cost of borrowing money
- Taxes: Property taxes (often escrowed)
- Insurance: Homeowner's insurance (and sometimes PMI)
The Mortgage Payment Formula
The standard formula for calculating a fixed-rate mortgage payment is:
M = P ร [r(1+r)^n] / [(1+r)^n - 1]
Where:
- M = Monthly payment
- P = Principal loan amount (home price minus down payment)
- r = Monthly interest rate (annual rate รท 12)
- n = Number of monthly payments (loan term in years ร 12)
Example Calculation
Let's say you're buying a $350,000 home with a 20% down payment ($70,000) and a 6.5% interest rate on a 30-year loan:
1. Loan amount: $350,000 - $70,000 = $280,000
2. Monthly rate: 6.5% รท 12 = 0.5417%
3. Number of payments: 30 ร 12 = 360
4. Monthly payment: Approximately $1,770 (principal + interest only)
Add estimated property taxes ($200/month) and insurance ($100/month), and your total monthly payment would be around $2,070.
Factors That Affect Your Payment
1. Interest Rate
Even a 0.5% difference can save or cost you tens of thousands over 30 years. For example, on a $300,000 loan:
- 6.0% โ $1,799/month
- 6.5% โ $1,896/month
- 7.0% โ $1,996/month
2. Down Payment
A larger down payment means:
- Lower monthly payments
- Potentially avoiding PMI (Private Mortgage Insurance)
- Better interest rates from lenders
3. Loan Term
- 30-year: Lower monthly payments, but more total interest
- 15-year: Higher monthly payments, but significantly less interest

Common Mortgage Questions
What is PMI?
Private Mortgage Insurance is required when your down payment is less than 20%. It protects the lender and typically costs 0.5%โ1% of the loan amount annually.
Should I pay points?
Discount points let you buy down your interest rate. Each point (1% of the loan) typically lowers the rate by 0.25%. If you plan to stay in the home for 7+ years, points can save you money.
Can I afford this home?
A common rule: your total monthly housing costs should not exceed 28% of your gross monthly income. Use our calculator to check!
