Mortgage PITI calculator

The old root /mortgage.html was a Tailwind lab that did not share classroom chrome. This is the same math — principal and interest, taxes, insurance, HOA, PMI over 80% LTV — in the library. Pair with DTI and how much house. Rate-and-term months to recoup: refinance break-even.

Quick answer: This calculator estimates monthly principal, interest, taxes, insurance, HOA, and PMI from the price, down payment, rate, and term you type. The sample is a $425,000 home with $85,000 down at 6.5% for 30 years. 6.5% and the 0.55% PMI factor are examples, not a lender quote.

Home price Down payment Interest rate % Term

Property tax / year Homeowners insurance / year HOA / month PMI rate % of loan / year (used if LTV > 80%)

Monthly housing

Estimate only. Year-1 interest is the first twelve months on the declining balance, not loan × rate. PMI is on only when loan-to-value is over 80%. 6.5% is a typed example, not a Freddie Mac print. Lenders quote their own MI factor, impounds, and credits. Amortization table: /tools/amortization. Qualify the payment with DTI. Educational only.

What this means for you

What this means for you: the headline is the monthly housing check in this model, before groceries and other debts. PMI appears only when the loan is over 80% of the price. Closing costs are not in the down payment. Compare that payment with the rest of your debts on the DTI calculator.
