What is included in the total monthly payment?

Principal and interest (the actual loan payment), property taxes, homeowner's insurance, and PMI if your down payment is under 20%. This gives you the real cost of owning the home each month.

What is PMI and when does it go away?

Private Mortgage Insurance (PMI) is required when your down payment is less than 20%. It typically costs 0.3-1.5% of the loan annually. PMI automatically drops off when you reach 20% equity (80% LTV).

How much down payment do I need?

A 20% down payment avoids PMI and results in lower monthly payments. However, many loans allow 3-5% down. FHA loans require 3.5% minimum.

What does a mortgage payment actually include?

A full mortgage payment is often described as PITI: Principal (reduces your loan balance), Interest (lender's fee), Taxes (property tax collected in escrow), and Insurance (homeowner's insurance plus PMI if your down payment is under 20%). This calculator shows principal and interest only — add your local tax and insurance estimates to get your true monthly cost.

When can I remove PMI?

Private Mortgage Insurance (PMI) is required when your down payment is below 20% and typically costs 0.5–1.5% of the loan per year. You can request cancellation once your equity reaches 20% through payments or appreciation. Lenders are legally required to automatically cancel PMI when your balance drops to 78% of the original purchase price.
