For many people today, calculating monthly mortgage payments is a common task. In this article, I will guide you through the process of calculating monthly mortgage payments in Excel.

Calculate monthly mortgage payment with formula


To calculate your monthly mortgage payment, follow these steps:

Step 1: Gather the Required Information:

Before proceeding with the calculation of your monthly mortgage payment, it's essential to gather the necessary information.

Loan Amount (B2)

Annual Interest Rate (B3)

Life Loan (B4)

Number of Payments per Year (B5)

Step 2: Calculate the Total Number of Payments Months

In the cell B6, use below formula and press Enter key to calculate the total number of payments months.


Step 3: Use the PMT Function to calculate the Monthly Mortgage Payment
Pro tip:

The PMT function in Excel is a financial function used to calculate the periodic payment, such as monthly loan or mortgage payments, based on constant payments and a constant interest rate. It's a useful tool for financial planning and analysis. The function requires three main arguments:

  • Rate (required): The interest rate for each period. In this example, it will be =B3/B5.
  • Nper (required): The total number of payment periods. In this example, it will be B6.
  • Pv (required): The present value, or the initial amount of the loan or investment. In this example, it will be B2.

Additionally, you can include two optional arguments:

  • Fv (optional): The future value or a cash balance you want to attain after the last payment is made (usually omitted or set to 0 for loans).
  • Type (optional): Indicates whether the payment is due at the beginning or end of the period (0 or omitted for end-of-period payments, 1 for beginning-of-period payments).

In the cell B7, use below formula and press Enter key to get the monthly mortgage payment.


Generally, the PMT function returns a negative value, for getting a positive value, please add a minus sign at the front of the PMT function.


Step 4: Calculate the Total Loan Cost

If you want to know how much your entire loan will cost in total, you can use the following formula and press Enter key to get the total loan amount.


// Monthly mortgage payment * total number of payments months

Step 5: Calculate the Total Interest

To get the total interests, use below formula and press Enter key.


// Total loan cost – loan amount
