Why your mortgage bill is higher than this calculator

A loan calculator like the one on this site shows principal and interest, the part of a mortgage payment that follows the amortization formula. Many homeowners send more than that each month. Lenders often collect property taxes and homeowners insurance along with the loan payment, and some loans add mortgage insurance. Together these are often called PITI: principal, interest, taxes, and insurance.

What each piece is

• Principal and interest (P&I): repays the loan and the interest on it. On a fixed-rate loan this amount stays the same for the whole term. This is what the 30-year and 15-year mortgage calculators estimate.
• Property taxes: set by your local taxing authorities, not your lender. Many lenders collect a monthly share into an escrow account and pay the bill for you when it is due.
• Homeowners insurance: protects the home and is usually required by the lender. It is often paid through escrow too.
• Private mortgage insurance (PMI): according to the CFPB, PMI may be required on a conventional loan when the down payment is less than 20 percent of the purchase price. It protects the lender, not you. It is most often paid as a monthly premium added to the mortgage payment, though some loans use an up-front premium at closing or both.
• HOA or condo dues: if the home is in an association, these are usually paid to the association directly, not through the lender, but they are still a monthly housing cost.

Government-backed loans, such as FHA, VA, and USDA loans, have their own mortgage insurance or fee rules that differ from conventional PMI. The CFPB notes that FHA and VA mortgages have different requirements for removing mortgage insurance and suggests contacting your servicer with questions. Your Loan Estimate shows any mortgage insurance or guarantee fee on your specific loan.

Why escrow amounts change

Your principal and interest stay fixed on a fixed-rate loan, but taxes and insurance do not. If your property is reassessed, your local tax rate changes, or your insurance premium goes up, your servicer adjusts the escrow part of your payment, usually after a periodic escrow review. So your total mortgage bill can go up or down even though your loan rate has not changed.

A worked example (illustration only)

All inputs here are hypothetical and are not current rates, tax rates, or premiums. Say a $250,000 loan at 6.75% for 30 years has a principal-and-interest payment of $1,621.50. If the annual property tax bill were $3,600 and annual homeowners insurance were $1,800, the monthly escrow would be $300.00 + $150.00 = $450.00. The planning total would be $2,071.50 a month before any PMI or HOA dues. Your own numbers could be very different. Use the figures from your own documents, not these.

Where to find your real numbers

• Loan Estimate: for most mortgages, the lender must give you this three-page form within three business days of your application. It shows the estimated interest rate, monthly payment, closing costs, and estimated taxes and insurance. The CFPB notes that a monthly PMI premium appears on page 1 in the Projected Payments section.
• Property tax: your county or city tax bill, or the listing's tax history for a home you are buying.
• Insurance: a written quote from an insurer.
• HOA: the association's current dues schedule.

To build a planning total, enter the loan amount, rate, and term in the calculator. Then take each annual tax and insurance amount, divide by 12, and add them to the principal-and-interest result, along with any monthly PMI or HOA dues. This gives you a rough planning figure. It is not an escrow analysis and not a lender quote.

Closing costs are separate

Origination charges, discount points, title costs, and prepaid items are paid at closing and do not appear in the monthly amortization schedule. Some of these fees are reflected in the APR on your Loan Estimate. See APR vs. interest rate.

Auto and personal loans

Auto loans and personal loans do not usually use escrow or PITI. If sales tax, title fees, or add-on products are rolled into an auto loan, enter the full amount financed as the loan amount in the auto loan calculator. Insurance, registration, fuel, and maintenance are ongoing costs outside the loan payment.

FAQ

• What does PITI stand for? Principal, interest, taxes, and insurance. Some people include PMI and HOA dues when they talk about the total monthly housing cost.
• Why doesn't this calculator include taxes and insurance? Those costs depend on the property, your location, and your insurer, and they change over time. The calculator sticks to principal and interest so the amortization schedule stays exact.
• Is PMI permanent? Usually not. According to the CFPB, for many single-family principal-residence mortgages that closed on or after July 29, 1999, you can ask in writing to cancel PMI once your balance is scheduled to reach 80% of the home's original value (or earlier, if extra payments get you there), provided you meet conditions such as a good payment history and no junior liens. The servicer generally must end PMI automatically when the balance is scheduled to reach 78%, as long as you are current. Different rules apply to FHA and VA loans and to lender-paid mortgage insurance, so check with your servicer.
• Why did my mortgage payment go up when my rate is fixed? Usually because the escrow part changed after a property tax or insurance increase.
