The calculator shows your monthly payment broken down into principal and interest, plus optional property tax, insurance, and PMI estimates.

Frequently Asked Questions

How much house can I afford?+
The general guideline is that your total monthly housing payment (principal, interest, tax, insurance) shouldn't exceed 28% of your gross monthly income. This is known as the 28/36 rule — total debt payments shouldn't exceed 36% of income.
What is PMI?+
Private Mortgage Insurance (PMI) is required when your down payment is less than 20% of the home price. It typically costs 0.5-1% of the loan amount annually and protects the lender (not you) if you default. It's automatically removed once you reach 20% equity.
