Mortgage Payment Calculator (Full PITI)

What PITI Means and Why It Matters

PITI stands for principal, interest, taxes and insurance. Lenders use this full number — not the bare P&I — when deciding whether to approve your loan. The principal portion reduces your balance each month. Interest is the cost of borrowing and makes up the majority of your early payments. Property taxes fund local government services and vary widely by county; in some areas they add $300 or more per month. Homeowner's insurance protects the collateral that secures the loan, and your lender requires it.

If your down payment is less than 20%, your lender adds private mortgage insurance (PMI), protecting them until you reach sufficient equity. HOA dues apply when your property sits in a managed community. All six line items flow through your escrow account into one single monthly withdrawal, which is why this calculator shows the combined total — the real number your household budget needs to absorb.

How Escrow Changes Your Payment Over Time

Even with a fixed interest rate, your monthly mortgage payment is not truly fixed. Your servicer performs an escrow analysis once a year, adjusting the amount collected for property taxes and homeowner's insurance. If your county raises assessments or your insurer increases premiums, the escrow portion of your payment rises and the servicer passes the cost directly to you.

Many homeowners on personal-finance forums report annual payment increases of $200 to $400 on a fixed-rate loan — and most had no idea it could happen when they signed closing documents. The calculator above shows your baseline PITI using today's inputs. To estimate future shifts, watch your annual escrow analysis statement and adjust the tax and insurance fields. Planning for a modest yearly increase helps you avoid the budget shock that catches many first-time homeowners off guard.

This estimate uses the inputs you entered. Your actual payment depends on your lender's escrow analysis, your county's tax rate, and the insurance policy you select.
