How to Calculate Monthly Mortgage Payment

The formula for calculating your monthly mortgage payment is:

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

Where:

  • M = Monthly mortgage payment
  • P = Principal loan amount (home price minus down payment)
  • r = Monthly interest rate (annual rate divided by 12)
  • n = Number of payments (loan term in years × 12)

Understanding Mortgage Components

Principal

The principal is the amount you borrow to buy your home. Each monthly payment includes a portion that reduces your principal balance.

Interest

Interest is the cost of borrowing money. In the early years of your mortgage, most of your payment goes toward interest.

Property Taxes

Property taxes are typically collected by your lender and held in an escrow account to be paid to your local government.

Home Insurance

Homeowners insurance protects your home and belongings. Lenders require this to protect their investment.

PMI (Private Mortgage Insurance)

If your down payment is less than 20%, you'll need to pay PMI. This protects the lender if you default on the loan.

Frequently Asked Questions

How much house can I afford with my salary?

A general rule is that your monthly mortgage payment should not exceed 28% of your gross monthly income. For example, if you earn $5,000 per month, your mortgage payment should be around $1,400 or less.

What is a good interest rate for a mortgage?

Mortgage rates vary based on market conditions, credit score, and loan type. As of 2025, rates between 6-7% are common for 30-year fixed mortgages. Shop around and compare offers from multiple lenders.

How much should I put as a down payment?

While 20% is the traditional down payment to avoid PMI (Private Mortgage Insurance), many lenders offer options with as little as 3-5% down. However, larger down payments mean lower monthly payments and less interest over time.

What is PMI and when can I remove it?

PMI (Private Mortgage Insurance) is required when your down payment is less than 20%. It protects the lender if you default. You can typically remove PMI once you have 20% equity in your home through payments or appreciation.

Is a 15-year or 30-year mortgage better?

A 15-year mortgage has higher monthly payments but significantly less total interest. A 30-year mortgage has lower monthly payments but more interest over time. Choose based on your budget and financial goals.
