Mortgage Payment Breakdown

PITI: The Four Parts of Your Payment

Your monthly mortgage payment is made up of four main components, collectively known as PITI. Two repay the loan itself; the other two are ownership costs your lender collects for you. Many buyers also pay PMI and HOA dues on top.

Only the first two parts depend on the loan maths. The rest are bolted on, which is why two homes with the same price can have very different monthly costs: a home in a high-tax area, or one with a large HOA fee, costs more each month than a cheaper-taxed home with the same mortgage. Lenders use the full payment — PITI plus PMI and HOA — when checking affordability, not just principal and interest. That is the figure our guide to how much house you can afford uses in the 28/36 rule.

Worked Example: A $400,000 Home at Today's Rate

Take a $400,000 home with an $80,000 down payment (20%), leaving a $320,000 loan on a 30-year fixed mortgage at 7.11% — the average 30-year fixed rate in Freddie Mac's survey for the week ending November 12, 2026. Property taxes are $4,800 a year, insurance $1,800 a year, no HOA dues. Run those inputs through the Mortgage Calculator:

Taxes and insurance add $550 a month on top of the loan payment — about a fifth of the total, and the part buyers most often underestimate: the loan payment is $2,152.66, but $2,702.66 leaves your account each month. Because the down payment is exactly 20%, there is no PMI here; put down less and a PMI line appears — see the second example below. Check current mortgage rates for the latest Freddie Mac averages: the rate moves the loan payment more than any other input.

Principal vs Interest: Why the Early Years Feel Slow

A fixed-rate mortgage uses the standard amortization formula to set the loan payment: M = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1), where P is the loan amount, r is the monthly interest rate and n is the number of payments. The payment stays the same every month, but the split inside it changes constantly: each month's interest is charged on the outstanding balance (interest = balance × annual rate ÷ 12), and whatever is left of the fixed payment goes to principal.

In month one, the balance is the full $320,000, so the interest is $320,000 × 7.11% ÷ 12 = $1,896.00, leaving just $256.66 of the $2,152.66 payment for principal. Only about 12% of the first payment reduces what you owe; the other 88% is the cost of borrowing. The first year tells the same story: of the $25,831.92 paid in principal and interest over twelve months, $22,649.62 goes to interest and only $3,182.30 to principal. After a year, the balance has fallen by just over $3,000 on a $320,000 loan.

The split flips slowly: each payment shrinks the balance, so next month's interest is smaller and the principal portion larger. By the final years, nearly the whole payment goes to principal. Over the full 30 years, total interest on this loan is $454,957.75 — more than the $320,000 borrowed — and the total cost of the home, all payments plus the $80,000 down payment, is $1,052,957.75. The Amortization Schedule Calculator shows the month-by-month split for any loan.

A Second Example: A $300,000 Loan at 6.5%

A smaller loan at a lower rate shows the same pattern. On a $300,000 loan at 6.5% for 30 years, principal and interest is $1,896.20 a month. In the first month, interest is $300,000 × 6.5% ÷ 12 = $1,625.00, leaving $271.20 for principal. Over the first year, $19,401.27 goes to interest and $3,353.18 to principal; total interest over the loan is $382,633.47.

This example also shows what PMI does. With less than 20% down, a conventional loan requires private mortgage insurance. Our calculator estimates PMI at 0.5% of the loan per year — $125 a month on a $300,000 loan, taking the monthly total to $2,021.20 before taxes and insurance. PMI protects the lender, not you, and builds no equity.

Escrow: How Taxes and Insurance Get Paid

Most lenders collect the money monthly and hold it in an escrow account (also called an impound account), rather than trusting borrowers to save up for a $4,800 tax bill and an $1,800 insurance premium. Each month, one-twelfth of the estimated annual tax bill and insurance premium is added to your payment — $400 and $150 in our example — and the lender pays the bills when they fall due.

Escrow is the most common reason a payment changes on a fixed-rate loan. The principal and interest part never moves, but property taxes and insurance premiums do. Once a year the lender reviews the escrow account: if taxes or insurance went up, the monthly collection rises to cover the shortfall, and your total payment rises with it. So a "fixed" mortgage payment is only fixed in its loan portion — the escrow portion follows your tax bills and insurance renewals. If your payment jumps unexpectedly, the annual escrow analysis statement is the first place to look.

PMI: What It Costs and When It Ends

Private mortgage insurance is charged on conventional loans when the down payment is below 20%. It protects the lender against default — it does nothing for the borrower — and it is priced as a yearly percentage of the loan. Our calculator estimates it at 0.5% a year: $125 a month on a $300,000 loan, $133.33 a month on a $320,000 loan. Actual PMI rates vary with your credit score and down payment size, so treat the estimate as a planning figure and check the real quote from your lender.

PMI does not last forever. Under the federal Homeowners Protection Act, your lender must automatically cancel PMI once your loan balance is scheduled to reach 78% of the home's original value, and you can ask for cancellation at 80% if you are current on payments. The simplest way to avoid PMI altogether is a 20% down payment — the Down Payment Calculator shows what that means for any home price.

What Your Mortgage Payment Does Not Include

The monthly payment is not the full cost of owning the home. Maintenance and repairs — a new roof, a broken boiler, a leaking pipe — are yours to pay, and they arrive on their own schedule. Utilities are separate, and often higher than in a rented home. HOA dues are usually billed separately rather than collected through escrow, even though our calculator shows them as part of the monthly picture. Moving costs, furnishing and closing costs sit outside the monthly figure entirely.

Three Ways to Lower Your Payment

Pay extra principal. Even a small extra payment, applied to principal, shortens the loan and cuts total interest sharply, because it shrinks the balance future interest is charged on. On our $400,000 example, adding $200 a month saves $122,082.30 in interest and pays the loan off 6 years and 10 months early — in 23 years and 2 months instead of 30. The Mortgage Payoff Calculator can run the same test on your own loan.

Refinance when rates fall. If rates drop well below your current rate, a new loan at the lower rate cuts the principal and interest portion of your payment. The test is the break-even — how long the monthly savings take to repay the closing costs — which our guide to whether you should refinance your mortgage works through with a real example.

Remove PMI. Once your loan balance falls to 80% of the home's original value, you can ask your lender to cancel PMI; it cancels automatically at 78%. On a $300,000 loan that removes an estimated $125 a month — a meaningful cut for a phone call and, in some cases, an appraisal.
