Annual taxes collected monthly and held in escrow by your lender.

Homeowners Insurance

PMI (Private Mortgage Insurance)

How additional payments can save you money

Frequently Asked Questions

Common questions about mortgage calculations and home loans

How accurate are the mortgage calculations?

Our mortgage calculator uses industry-standard formulas and provides highly accurate estimates. However, actual payments may vary slightly due to lender-specific fees, rounding practices, and local tax variations. Always consult with your lender for final payment amounts.

When should I consider making extra payments?

Consider extra payments after you have an emergency fund, are maximizing employer 401(k) matching, and have paid off higher-interest debt. Extra payments are most effective early in the loan term and when you have stable finances.

What's included in the monthly payment estimate?

Our calculator includes principal and interest (P&I), property taxes, homeowners insurance, private mortgage insurance (PMI) when applicable, HOA fees, and other monthly costs you specify. This gives you a comprehensive view of your total housing payment.

How do I know when PMI will be removed?

PMI is typically removed when you reach 20% equity in your home (80% loan-to-value ratio). Our calculator shows when this occurs based on your payment schedule and any extra payments. You may need to request PMI removal from your lender.
