Learning how to use the PMT function in Excel can be incredibly useful for anyone who needs to calculate loan payments or understand the cost of financing. This powerful function can help you quickly determine how much you need to pay each period to cover a loan, given the loan amount, interest rate, and number of periods. By following a few simple steps, you’ll be able to master this function and make informed financial decisions.
How to Use PMT Function in Excel
The PMT function in Excel helps you calculate the payment for a loan based on constant payments and a constant interest rate. It’s a handy tool for anyone dealing with loans and mortgages. Follow these steps to use the PMT function effectively.
Step 1: Open Excel
Open Excel on your computer.
Before diving into the PMT function itself, make sure you have your Excel software open and ready to go. This might seem obvious, but it’s the first step in getting anything done in Excel.
Step 2: Enter Your Data
Enter the loan amount, interest rate, and number of periods in separate cells.
To calculate the payment amount, you’ll need to break down your data. Input the loan’s principal amount (the total amount borrowed), the annual interest rate, and the number of payment periods (months or years) into individual cells. Label each cell to keep things organized.
Step 3: Select the PMT Function
Click on a blank cell and type =PMT(.
This is where the magic happens. In a new cell, type =PMT( to start the function. Once you type the first parenthesis, Excel will prompt you for the required arguments: interest rate, number of periods, and loan amount.
Step 4: Input the Interest Rate
Type the interest rate divided by the number of payment periods per year.
The interest rate often needs to be converted to a monthly or period-based rate. For example, if your annual interest rate is 6%, you would type 6%/12 (for monthly payments).
Step 5: Input the Number of Periods
Type the total number of payment periods.
Here, you’ll need to specify the total number of payments. If you’re paying monthly for 5 years, you would enter 5*12.
Step 6: Input the Loan Amount
Type the loan amount preceded by a minus sign.
Finally, input the loan amount, but remember to precede it with a minus sign. This tells Excel that the loan amount is an outgoing payment.
Step 7: Complete the Function
Close the parentheses and press Enter.
Finish off your PMT function by closing the parenthesis and hitting Enter. Excel will instantly calculate the periodic payment amount for you.
After completing these steps, Excel will display the required periodic payment amount in the cell where you entered the PMT function.
Tips for Using PMT Function in Excel
- Always use consistent units. If you break down the annual interest rate into monthly, make sure your number of periods is in months too.
- Use cell references instead of typing numbers directly into the function. This makes it easier to update values if needed.
- Familiarize yourself with related functions like IPMT (interest payment) and PPMT (principal payment) for a fuller picture of your finances.
- Double-check your interest rate format. Remember to convert percentages to decimals. For example, 6% should be entered as 0.06.
- Use the built-in Excel help feature for more advanced options, like additional arguments for type and FV (future value).
