Our guide will walk you through calculating NPER in Excel, offering a crystal clear path to mastering this potent tool. And we'll even introduce a cost-free office software suite to amplify your productivity.
What is NPER Function in Excel?
The NPER function in Excel is a financial function that calculates the number of periods for an investment based on a constant interest rate and consistent, periodic payments. The function takes into consideration several parameters, including the interest rate per period (Rate), the payment made each period (Pmt), and the present value of the total amount (Pv).
Syntax
=NPER(rate, pmt, pv, [fv], [type])
For example, if you want to calculate the number of payment periods required to reach a savings goal of $10,000 with a monthly deposit of $200, an annual interest rate of 5%, and payments made at the end of each month, the formula would be;
=NPER(5%/12, -200, 0, 10000)
It also optionally considers the future value (Fv), or the cash balance aimed to be reached after the last payment, and the type of payment schedule (Type), which indicates whether monthly or quarterly payments are due. By providing these details, the NPER function can help forecast the lifespan of an investment or loan.
Basic Usage of NPER Function
These are some simple steps to use the NPER Excel function:
Step 1: Open an Excel sheet.
Step 2: Identify cells for annual interest rate, monthly payment, initial investment, savings goal, and payment due time.
Step 3: Enter the relevant values into these cells.
Step 4: In a new cell, type =NPER(.
Input the annual interest rate divided by 12, followed by a comma.
Input the monthly payment (negative), followed by a comma.
Input the initial investment (negative), followed by a comma.
Input the savings goal, followed by a comma.
Step 5: Input when the payment is due (0 for the end of the period, 1 for the beginning), close with ), and hit Enter.
Using NPER Function in Different Payment Conditions
Example 1
Ms. Karuna, an employee in a corporate firm based in Bangalore, had taken an education loan of $250,000 for her studies. She earns a monthly income of %40,000. After meeting her monthly expenses, she can afford to pay an EMI of $15,000 towards her loan. The interest rate on her education loan is 13.5% per annum. She is unsure how long it would take her to fully repay her loan, so we will help her estimate the loan repayment timeline.
In the Excel sheet, cell B1 contains the loan amount borrowed by Ms. Karuna.
Cell B2 contains the annual interest rate on the loan.
Cell B3 shows the amount she can pay monthly to repay the loan.
We will use the NPER function in Excel in cell B4 to determine the repayment period in months.
After calculating, we discovered that she would take approximately 18.56 months to clear the loan.
To understand the formula used:
B2/12: We have the annual interest rate in cell B2. Since Ms. Karuna makes monthly payments, we need to convert the annual interest rate into a monthly interest rate by dividing it by 12.
-B3: This signifies the monthly payment made by Ms. Karuna to repay her loan. As this is a cash outflow, we represent it as a negative number.
B1: This is the amount of loan borrowed by Ms. Karuna for her studies.
So, with a monthly EMI payment of $15,000, Ms. Karuna can repay her loan in approximately 18.56 months.
Example 2
Mr. John is planning for his retirement and has set a financial goal of $10,000,000. He is considering a monthly investment of $10,000 at an annual interest rate of 14.5%. However, Mr. John is uncertain about the period required to accumulate his target amount.
Now, we will utilise the NPER function in the B4 cell of our spreadsheet. This formula requires several inputs:
The B1/12 component represents the yearly interest rate of 14.5%, divided by 12 to accommodate Mr. John's monthly investment schedule.
The second element is 0, which indicates the PMT or the regular payment amount. As Mr. John's goal is to grow his investment rather than repay a debt, this figure is set to zero.
Next, -B2 is the initial amount invested. It is denoted as a negative value to reflect the outgoing funds.
Finally, B3 symbolises the desired future value of Mr. John's investment, which is $10,000,000 in this case.
By applying this formula, we find that Mr. John needs to make investments for 575.12 months to reach his retirement goal. Therefore, he needs to invest consistently for about 47.93 years (obtained by dividing 575.12 by 12).

FAQs
How do you calculate PV?
Calculating the present value (PV) involves a few steps. First, you identify your future cash flows for each period, denoted as Ci, where I can range from 1 to k. Then, you set your discount rate (r), which is chosen based on market trends or investor risk tolerance. You must also establish the number of periods (n) for each cash flow.
What is IRR in Excel?
