Understanding Your Mortgage Payment
A monthly mortgage payment typically includes four components called PITI: Principal, Interest, Taxes, and Insurance. Understanding each helps you budget accurately and compare loan options. Many buyers focus only on principal and interest, leading to budget surprises.
PITI Breakdown
Principal: Amount going toward loan balance. Interest: Cost of borrowing, largest portion early in loan. Property Taxes: 1-3% of home value annually, collected in escrow. Homeowners Insurance: $800-$2,000/year typical, required by lenders. PMI: Required if down payment under 20%, typically 0.5-1% of loan annually. HOA Dues: Additional if applicable.
The Mortgage Formula
Monthly P&I = P x [r(1+r)^n] / [(1+r)^n - 1]. Example: $300,000 loan at 7% for 30 years. r = 0.07/12 = 0.00583. n = 360. Monthly P&I = $1,996. Add estimated taxes ($250/month), insurance ($150/month), PMI if applicable. Total payment: ~$2,400/month.
Factors Affecting Your Payment
Loan amount: Higher principal = higher payment. Interest rate: 1% difference = significant change. Loan term: 15-year = higher payment, much less interest. Down payment: 20%+ eliminates PMI. Credit score: Better score = lower rate. Location: Affects taxes and insurance costs.
Key Takeaways
Monthly payment includes more than just principal and interest. Factor in taxes and insurance for true cost. 20% down eliminates PMI. Shop rates from multiple lenders. Consider total payment, not just P&I. Use our Mortgage Calculator to estimate your full payment.
