What is Mortgage Calculator?

This mortgage calculator goes beyond basic P&I to give you a complete picture of homeownership costs. It calculates your total monthly payment (PITI) including property tax, homeowners insurance, and PMI when applicable. You will see exactly where every dollar goes each month.

Additional features include a yearly amortization schedule, an extra payment calculator showing how much you can save, and an affordability check using the 28% rule. All calculations use US dollar formatting and happen locally in your browser.

FAQ

What is PITI?
PITI stands for Principal, Interest, Taxes, and Insurance. It represents your total monthly mortgage payment. Lenders use PITI to determine how much home you can afford, typically limiting it to 28% of your gross monthly income.
When is PMI required?
Private Mortgage Insurance (PMI) is typically required when your down payment is less than 20% of the home price. PMI protects the lender if you default. It can be removed once you reach 20% equity through payments or home value appreciation.
How much can I save with extra payments?
Even small extra payments can save thousands in interest and shave years off your mortgage. For example, an extra $200/month on a $300,000 30-year mortgage at 6.5% could save over $90,000 in interest and pay off the loan 7+ years early.
What is the 28% rule?
The 28% rule is a common lending guideline that your total monthly housing payment (PITI) should not exceed 28% of your gross monthly income. This helps ensure you are not overextending yourself financially.
