Mortgage Calculator

A home is the largest purchase most people make in their lives, and the monthly mortgage payment includes far more than just principal and interest. The PITI breakdown — Principal, Interest, Tax, and Insurance — captures the four standard components of a typical monthly payment, and when your down payment is less than 20%, Private Mortgage Insurance (PMI) adds a fifth.

Each component varies independently: interest depends on your credit score and current market rates, property tax depends on your state and county (typically 0.5% to 2.5% of home value annually), insurance depends on home value and area risk, and PMI is roughly 0.3% to 1.5% of the loan amount annually. Utilify's calculator breaks all of these out separately so you understand exactly where each dollar of your monthly payment goes — and lets you toggle PMI on or off to see the impact of a 20% down-payment goal.

PMI is worth understanding because it is the one cost you can deliberately avoid or remove. Lenders require it when your down payment is under 20% because the loan is riskier to them — but it protects the lender, not you. The good news is that it is not permanent: as you pay down the balance (or the home appreciates) and your loan-to-value ratio improves, you can typically request cancellation at 80% LTV, and lenders are generally required to drop it automatically at 78%.

The rate you lock has an outsized effect over a 30-year term. Because interest compounds across hundreds of payments, even a 0.25% difference between two lender offers can add up to tens of thousands of dollars over the life of the loan. That is why it pays to shop multiple lenders and to weigh paying discount points up front against the monthly savings they buy.

Two costs this estimate intentionally leaves out are HOA dues and closing costs. Homeowners association fees, where they apply, are billed separately and can run from modest to substantial, and closing costs (typically 2–5% of the purchase price) are a one-time expense at signing rather than part of the monthly payment. Factor both into your overall budget alongside the PITI figure this tool produces.
