How is your monthly mortgage payment calculated?

Your monthly mortgage payment is determined using the standard amortization formula:

M = P [ r(1 + r)^n ] / [ (1 + r)^n - 1 ]

Where:

  • M = your total monthly mortgage payment
  • P = the principal loan amount (home price minus your down payment)
  • r = your monthly interest rate (annual rate divided by 12)
  • n = total number of payments (loan term in years multiplied by 12)

What makes up your total payment

The formula above calculates only the principal and interest portion of your payment. Your actual monthly obligation also includes:

  • Principal & Interest (P&I): The core of your payment. Early in the loan, most goes toward interest. Over time, more goes toward paying down the principal balance.
  • Property Taxes: Local governments assess property taxes based on your home's assessed value. These are typically collected monthly by your lender and held in an escrow account.
  • Homeowners Insurance: Required by your lender to protect against damage, theft, and liability. Premiums vary based on location, home value, and coverage level.
  • Private Mortgage Insurance (PMI): If your down payment is less than 20%, your lender will require PMI to offset the higher risk. PMI is automatically removed once you reach 78% loan-to-value.

Frequently Asked Questions

What's included in a mortgage payment?+

A typical mortgage payment is often referred to as PITI, which stands for the four components that make up your monthly obligation:

  • Principal: The portion that goes toward paying down your loan balance.
  • Interest: The cost your lender charges for borrowing the money.
  • Taxes: Property taxes assessed by your local government, typically collected monthly and held in escrow.
  • Insurance: Homeowners insurance protects against damage and liability. If your down payment is less than 20%, you will also pay private mortgage insurance (PMI).

How does the loan term affect my payment?+

The loan term is the length of time you have to repay your mortgage. A shorter term means higher monthly payments but significantly less interest paid over the life of the loan.

With a 30-year fixed mortgage, your payments are spread over a longer period, keeping them more affordable each month. However, you pay much more in total interest.

A 15-year fixed mortgage will have noticeably higher monthly payments, but you will build equity faster and pay far less interest overall -- often saving tens of thousands of dollars.

How does my down payment affect things?+

A larger down payment reduces your loan amount, which lowers both your monthly payment and the total interest paid over the life of the loan.

Putting down at least 20% also eliminates the need for private mortgage insurance (PMI), which can save you hundreds of dollars per month. Even a few extra percentage points on your down payment can make a meaningful difference in your overall housing costs.

What is PMI and how can I avoid it?+

Private mortgage insurance (PMI) is required by lenders when your down payment is less than 20% of the home price. It protects the lender -- not you -- in case you default on the loan.

PMI typically costs between 0.3% and 1.5% of the original loan amount per year. To avoid PMI, you can make a down payment of 20% or more. If you already have PMI, you can request removal once your loan-to-value ratio reaches 80%, and your lender is required to automatically cancel it when you reach 78% LTV.

Can I lower my monthly payment?+

There are several strategies to reduce your monthly mortgage payment:

  • Make a larger down payment to reduce your loan amount and potentially eliminate PMI.
  • Choose a longer loan term (e.g., 30 years instead of 15) to spread payments over more time.
  • Secure a better interest rate by improving your credit score, shopping multiple lenders, or waiting for favorable market conditions.
  • Buy down your rate with points -- paying upfront to reduce your interest rate can lower your monthly payment over the life of the loan.

What are closing costs?+

Closing costs are the fees and expenses you pay when finalizing your mortgage, typically ranging from 2% to 5% of the loan amount. They are paid on your closing day in addition to your down payment.

Common closing costs include:

  • Loan origination fees
  • Appraisal fee
  • Title search and title insurance
  • Attorney fees
  • Recording fees
  • Prepaid taxes and insurance (escrow)

Some lenders offer credits or no-closing-cost options, though these usually come with a slightly higher interest rate.
