Total monthly housing cost including taxes, insurance, PMI, and HOA

What PITI Covers

PITI stands for Principal, Interest, Taxes, and Insurance — the four components lenders bundle into a single monthly payment in many mortgages. Adding PMI (private mortgage insurance, required when deposit is below 20 percent) and HOA (homeowner association) fees gives the complete monthly housing cost.

Why PITI Beats P+I Alone

Mortgage shoppers often focus on principal and interest only and are surprised by the real monthly cost after closing. PITI can be 30-40 percent higher than P+I for properties with high taxes, expensive insurance, HOA dues, and PMI. Budgeting from PITI instead of P+I prevents cashflow shock during year one of ownership.

Run it with sensible defaults

Using loan principal of 300,000, interest rate of 6.5, loan term of 30, annual property tax of 4,500, the calculation works out to 2,396.34. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Loan Principal, Interest Rate, Loan Term, Annual Property Tax, and Annual Home Insurance — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

How the math works

Principal and interest from standard amortization formula, taxes and insurance converted from annual to monthly, PMI and HOA added as-is. Results are estimates for illustration purposes only. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Why this matters before you sign

A mortgage is usually the biggest single financial commitment a person makes. The difference between a well-chosen product and a hasty one can run into tens of thousands over the life of the loan. Running the numbers here before committing is the cheapest form of due diligence available.

What this doesn't capture

The figure excludes arrangement fees, valuation costs, legal fees, insurance, and any early-repayment charges — those can add several thousand to the headline cost. Rate changes at renewal for fixed-term deals will shift the picture further. Use this for the core interest/principal math and add the other costs on top.
