How to Calculate Your Mortgage PaymentsCalculating mortgage payments can seem daunting, but with TipRank's Mortgage Calculator, you can effortlessly navigate through the numbers.

Home Price

Enter the purchase price if you're buying a new home, or the current market value if you're refinancing your existing property.

Down Payment

Specify the amount you plan to pay upfront if you're buying, or the equity you've built up if you're refinancing. Down payment refers to the initial lump-sum payment towards the home, while home equity is the property's value minus any outstanding loans. You can input this as either a dollar amount or a percentage.

Loan Term

Choose the duration of your loan. Common terms are 30, 20, 15, or 10 years, but you're free to select a term that suits your financial situation.

Interest Rate

Input the interest rate you anticipate. Keep in mind that rates may differ depending on whether you're purchasing a new home or refinancing an existing loan. As you populate these fields, the calculator will dynamically update its calculations to display your estimated monthly principal and interest payments.
Glossary of Mortgage Terms


The process of paying off a loan over time through regular payments. An amortization schedule details how much of each payment goes toward the principal and how much goes toward interest.

Annual Percentage Rate (APR)

The annual rate charged for borrowing, expressed as a single percentage that represents the actual yearly cost of the loan.

Closing Costs

One-time fees and expenses paid at the closing of a mortgage transaction, separate from the loan itself.

Down Payment

The initial upfront payment made when buying a home, usually expressed as a percentage of the total property price.


The value of ownership built up in a property, calculated by taking the current market value minus the remaining mortgage balance.


An account held by a third party to manage the payment of property taxes and insurance.

Fixed-Rate Mortgage

A mortgage with an interest rate that remains the same for the entire term of the loan.


The cost of borrowing money, typically expressed as an annual percentage rate.

Loan-to-Value Ratio (LTV)

The ratio of the loan amount to the appraised value or sales price of the property, expressed as a percentage.

Mortgage Insurance

Insurance that protects the lender in case the borrower defaults on the loan. Typically required for loans with an LTV ratio greater than 80%.


The original amount of money borrowed, not including interest.


The process of obtaining a new mortgage to replace an existing one, often to obtain a lower interest rate or to convert equity into cash.


The length of time over which the loan must be repaid. Common terms are 15, 20, or 30 years.

Understanding the Mortgage Payment FormulaWhen it comes to calculating your mortgage payments, a specific formula is used to determine how much you'll owe each month. While our mortgage calculator handles these calculations automatically, knowing the formula can help you understand the financial mechanics behind your loan.

The Formula

The standard formula to calculate a monthly mortgage payment is:
M = Monthly payment
P = Principal loan amount
r = Monthly interest rate (annual interest rate divided by 12)
n = Number of payments (loan term in months)

Breaking Down the Formula

Monthly Payment (M):
This is the amount you'll pay each month, which includes both the principal and the interest.
Principal Loan Amount (P):
This is the initial amount borrowed to purchase the home.
Monthly Interest Rate (r):
Your annual interest rate divided by 12 (the number of months in a year). For example, if your annual interest rate is 6%,
the monthly rate would be
Number of Payments (n):
This is the total number of monthly payments you'll make over the life of the loan. For a 30-year term, n = 30 × 12 = 360.


Let's say you have a $300,000 loan with a 4% annual interest rate, and you've chosen a 30-year term.
To find the monthly interest rate, you would divide the annual rate by 12:
or 0.33% in decimal form.

Plugging these into the formula, your monthly payment would be calculated as follows:
In this example, your estimated monthly mortgage payment would be approximately $1,432.25.
