What Goes Into a Mortgage Payment?

Principal, interest, taxes, insurance and the other costs behind a monthly housing payment.

When people ask "what is my mortgage payment?", the answer depends on which costs are included. The number a lender quotes for the loan itself is often lower than what you actually send each month. Understanding each piece helps you budget realistically and compare homes fairly.

The four core pieces: PITI

Lenders often describe a payment as PITI. Principal is the part that reduces what you owe. Interest is the cost of borrowing, charged on the remaining balance. Taxes are local property taxes. Insurance is homeowners insurance, which lenders require. Taxes and insurance are frequently collected by the lender each month into an escrow account and paid on your behalf when bills come due.

A worked example

Consider a home bought with a $320,000 loan at 6.5% for 30 years. Principal and interest comes to $2,022.62 a month. Add $400 a month for property taxes ($4,800 a year) and $150 for insurance ($1,800 a year), and the payment becomes about $2,572.62. Over the full 30 years you would pay roughly $408,142 in interest on the loan alone, which is why the rate and term deserve as much attention as the home price.

Costs that can be added on top

Private mortgage insurance (PMI) is commonly required on conventional loans when the down payment is below 20%. It protects the lender, not you, and it can often be removed once you have built enough equity. HOA dues apply in many condos and planned communities and are paid separately from the mortgage. Some buyers also finance part of their closing costs, which increases the loan amount.

Why your payment can change

• Property tax reassessments can raise your escrow amount.
• Homeowners insurance premiums can increase at renewal, especially in areas with higher weather risk.
• An adjustable-rate mortgage can reset to a new rate after its fixed period.
• PMI may fall away when your balance drops far enough.

Principal and interest on a fixed-rate loan does not change for the life of the loan, but everything else can.

Term: 30 years or 15?

A shorter term raises the payment but cuts interest sharply. On the same $320,000 at 6.5%, a 15-year loan has a payment of $2,787.54 instead of $2,022.62, but total interest falls to about $181,758. Lenders often price shorter terms slightly lower, though the exact rate depends on the market and your profile.

The effect of extra payments

Paying even a modest amount extra goes straight to principal. Adding $200 a month to the 30-year example would pay the loan off in about 23 years and 5 months and reduce total interest to roughly $302,714. Before doing this, confirm your loan has no prepayment penalty and that extra money is applied to principal.

Questions to ask a lender

• What is the APR, and what fees does it include?
• Is the quoted payment principal and interest only, or does it include escrow?
• How much PMI would I pay, and how can it be removed?
• Are there points or prepayment penalties?

You will also receive an official Loan Estimate, which is the best document for comparing offers side by side. To test your own price, down payment and rate, use the mortgage calculator.

Closing costs and cash to close

Beyond the monthly payment, buyers pay one-time closing costs, which commonly include lender fees, title insurance, appraisal and prepaid taxes and insurance. These are separate from your down payment, so plan cash reserves for both.
