PITI is the sum of Principal, Interest, Tax, and Insurance — the four standard components of a US mortgage payment. Many borrowers focus only on principal and interest (P&I) and underestimate their actual monthly housing cost by 20-40%. This calculator includes property tax (typically 0.5-2.5% of home value annually), homeowners insurance ($800-$2,500/year), and PMI when applicable.
PMI (private mortgage insurance) kicks in when your down payment is under 20% of the home price. We estimate it at 0.5% of the loan principal per year, which is typical for conventional loans. PMI drops off automatically once you reach 22% equity (or 20% with a request).
20% down has been the historical 'no PMI' threshold. With less, you pay PMI (often $100-$300/month for typical loans) until you build enough equity. The PMI cost over a few years can exceed several thousand dollars, so larger down payments save real money.
Larger down also reduces the loan principal, which reduces interest paid over the life of the loan. On a $400k home at 6.5% for 30 years: 20% down means $320k loan and ~$408k total interest. 5% down means $380k loan and ~$485k total interest — $77k extra. Plus PMI.
Property tax: look up your county's millage rate or use 1-2% as a national US average. Insurance: ~$1,200/year is typical. HOA: only relevant if you're buying in a community with one. The calculator's PMI estimate is an approximation — your actual rate depends on credit score and loan type.
For more conservative budgeting, run the calculator with a slightly higher rate than today's. Mortgage rates can rise between rate-lock dates; planning for rate volatility is wise. Also consider closing costs (typically 2-5% of the loan amount) which are not modeled here.
The principal-and-interest payment uses the standard annuity formula M = P × r ÷ (1 − (1 + r)⁻ⁿ), where P is the loan amount after the down payment, r is the annual rate divided by 12, and n is the number of monthly installments. The amortization table above applies the same formula month by month: each payment first covers the interest accrued on the remaining balance, and the rest reduces the principal.
The PITI breakdown (principal, interest, taxes, insurance) and the PMI rule of thumb follow the definitions published by the U.S. Consumer Financial Protection Bureau; the exact pages are listed under Sources below. Lender quotes can still differ because of escrow handling, fees, and rate rounding, so treat the result as a planning figure rather than an offer.
This adds tax, insurance, PMI, and HOA — the real-world costs above just principal and interest. Use loan-calculator for non-housing loans.
Approximate. PMI varies from 0.3% to 1.5% per year depending on credit score, down payment, and loan type. We use 0.5% as a typical mid-range figure.
15-year saves substantial interest but doubles the monthly P&I. 30-year offers flexibility. Choose based on cash flow and other investment options. The calculator shows total interest for each term.
Search '[your county] property tax rate' or look on your county assessor's website. Typical US rate is 1-2% of home value annually.
Only if your home has one. HOAs vary from $0 (no HOA) to $1,000+/month for high-amenity buildings.
Lenders may include escrow for tax/insurance differently, may bundle PMI into the rate (LPMI), and may charge fees this calculator doesn't model. Always check the lender's official Loan Estimate.
No. Run the calculator with the new rate after refinancing for the updated payment.
No. Calculation runs locally.
