How the mortgage calculator works

This calculator uses the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n − 1], where M is the monthly principal-and-interest payment, P is the loan amount, r is the monthly interest rate, and n is the number of monthly payments.

PITI breakdown

Most US lenders escrow property taxes and homeowners insurance into your monthly payment, then pay those bills on your behalf when they come due. This means your real monthly outflow includes all four PITI components, not just principal and interest.

PMI (Private Mortgage Insurance)

When your down payment is below 20% of the home price, lenders require PMI to protect themselves against default. PMI is typically 0.3%–1.5% of the loan amount per year. Once your loan balance drops to 80% of the original home value, you can request PMI cancellation.

30-year vs 15-year

A 30-year mortgage on $360,000 at 6.85% costs around $2,360/month in P&I with total interest of about $490,000 over 30 years. The same loan as a 15-year at 6.0% would be roughly $3,038/month but only $187,000 in total interest — about $300,000 saved.

Frequently Asked Questions

What is included in the monthly mortgage payment?+
A complete mortgage payment includes four components, known as PITI: Principal (paying down the loan balance), Interest (cost of borrowing), Taxes (property tax escrowed monthly), and Insurance (homeowners insurance, plus PMI if your down payment is under 20%). HOA dues, if applicable, are separate.
How much down payment do I need to avoid PMI?+
Most lenders require Private Mortgage Insurance (PMI) when your down payment is less than 20% of the home price. PMI is typically 0.3% to 1.5% of the loan annually. This calculator adds 0.5% automatically when down payment is below 20%.
Should I choose a 15-year or 30-year mortgage?+
30-year mortgages have lower monthly payments but cost significantly more in total interest. 15-year mortgages save 50%+ in interest but require ~50% higher monthly payments. Try both in the calculator above to see your specific numbers.
How accurate is this mortgage calculator?+
Calculations use the standard amortization formula used by lenders. Your actual rate will depend on credit score, down payment, loan type (conventional, FHA, VA), and current market conditions. Get a real quote from a lender for binding terms.
What is amortization?+
Amortization is the process of paying off a loan through scheduled payments. Early in the loan, most of your payment goes to interest. Over time, more goes to principal. Click 'Show amortization schedule' above to see this play out year by year.
