Advanced Mortgage Analyser

PITI stands for Principal, Interest, Taxes, and Insurance - the four parts of a typical monthly mortgage payment. Budgeting on principal and interest alone understates the true cost of owning, because property taxes and home insurance (and sometimes mortgage insurance) can add a meaningful amount every month. Lenders assess affordability on the full PITI figure, not just the loan repayment, so seeing all four together gives you a realistic picture of what the home will actually cost you each month.

Any payment above your scheduled amount is applied directly to the loan principal, which lowers the balance that future interest is charged on. Because interest is calculated on a smaller balance from that point forward, even modest regular overpayments can remove years from the term and save a large amount of total interest. This calculator lets you test an extra monthly amount so you can see the reduction in both the payoff date and the lifetime interest before you commit.

A shorter term usually carries a slightly lower interest rate and forces disciplined repayment, but it commits you to a higher required monthly payment. A longer term with voluntary overpayments keeps your obligated payment low for flexibility while still letting you accelerate when you can. Neither is universally correct: the shorter term is cheaper if you are certain you can afford it, while the longer term plus overpayments is safer if your income varies.

No. This is an educational estimate based on the figures you enter. Real property taxes and insurance premiums change over time, and if you have a variable or adjustable rate your interest cost will move with it. Treat the output as a planning tool to compare options, and confirm the exact numbers with your lender and a current tax and insurance quote before making a decision.
