# Basic Financial Calculator Atlantic Federal Credit Union

The net present value (NPV) of a series of unequal payments made at regular intervals, assuming a fixed interest rate per interval. Suppose \$100 (PV) is invested in a savings account that pays 10% interest (I/Y) per year. This \$110 is equal to the original principal of \$100 plus \$10 in interest. \$110 is the future value of \$100 invested for one year at 10%, meaning that \$100 today is worth \$110 in one year, given that the interest rate is 10%.

This finance calculator can be used to calculate the future value (FV), periodic payment (PMT), interest rate (I/Y), number of compounding periods (N), and PV (Present Value). Each of the following tabs represents the parameters to be calculated. It works the same way as the 5-key time value of money calculators, such as BA II Plus or HP 12CP calculator. The PMT Function[1] is categorized under financial Excel functions. The function helps calculate the total payment (principal and interest) required to settle a loan or an investment with a fixed interest rate over a specific time period. Thanks to the Excel financial functions such as RATE, PPMT and IPMT, computing the monthly or any other periodic payment for a loan is easy.

## Annuity calculations

Perhaps the most popular function in Excel is the sum (SUM) functionAlso represented by Σ, the sum function adds up a column or row of numbers., which adds up a long list of numbers. The input for the Sum function are the cells to be added together. Suppose you take out a \$50,000 loan at 12% for 10 years, with one payment per year. Begin – specifies whether payments are made at the beginning (1) or end of each period (0). Most loans are paid at the end of each period (the first payment is made at the end of the first month, etc.), in which case this value would be zero. The present value (PV) of a series of equal payments made at regular intervals, assuming a fixed interest rate per interval.

## Finance Class

While most basic financial calculations can technically be done by hand, professors generally allow students to use financial calculators, even during exams. It’s not the ability to perform calculations by hand that’s important; it’s the understanding of financial concepts and how to apply them using these handy calculating tools that were invented. Our web-based financial calculator can serve as a good tool to have during lectures or homework, and because it is web-based, it is never out of reach, as long as a smartphone is nearby. The inclusion of a graph and a schedule, two things missing from physical calculators, can be more visually helpful for learning purposes. The tutorial shows how to use PMT function in Excel to calculate payments for a loan or investment based on the interest rate, number of payments, and the total loan amount. Create a properly formatted spreadsheet that calculates the payments on a business loan.

• The intention is to force lenders to be honest about the terms of the loan and to allow buyers to comparison shop loans.
• The function references three other numbers in the same illustration.
• We encourage you to seek personalized advice from qualified professionals regarding all personal finance issues.

Suppose a consumer has taken out a \$400,000 mortgage loan to finance the purchase of a house. Periodic Payment (PMT) can be included but is not a required element. Because there are so few numbers the assumptions area and the calculations are combined. Note that it is hard to even follow a complex mathematical formula when it is written in Excel.

## PMT Excel Function Syntax

Think of formulas as things that you build whereas functions are things that you “buy.” We put buy in quotes because many functions, including the payment function, are bundled with Excel. That is part of the way that Excel maintains its leadership in the spreadsheet marketplace. Of course the pmt( function only works with fixed interest rates. In the prior chapter we looked at Excel formulas and how to construct them. In many cases, we want to create our own formulas so we have a clear idea of how the information is constructed.

• In all cases, the balance after the last payment is assumed to be \$0, and the payments are due at the end of each period.
• On the other hand, small businesses without a prior track record sometimes have trouble securing a bank loan.
• Balloon – (future value) is the value of the loan at the end of the period.
• The mortgage loan has an annual interest rate of 6.00% per annum, with payments made on a monthly basis at the end of each month.
• Periodic Payment (PMT) can be included but is not a required element.

The pmt( function calculates the periodic payment required to pay off a loan. The pmt( function (short for payment) calculates the periodic payment required to pay off a loan. This exercise allows you to create a loan payment calculator and perform a sensitivity analysisAn analysis of how the calculation results vary with changes in the initial assumptions.

## The Time Value of Money (TVM)

The Excel “PMT” function is used to determine the payments owed to a lender by a borrower on a financial obligation, such as a loan or bond. Before you go ahead and borrow money, it stands to reason to compare different loan conditions to find out the options that suit you most. First time home buyers are often shocked to find that their finance charge actually exceeds the amount of the loan. In other words, over the life of the loan they end up paying around twice the closing price of the home. Home loans have higher finance charges because they are often stretched out over thirty years—which is a lot of time to compound interest. Similarly, if we were to stretch our \$5,000 business loan out over thirty years, the finance charge climbs to \$8,208, which exceeds the amount of the loan.

Determining the payments on a loan is an important part of forecasting costs. The financial formula that calculates loan payments is fairly complex. However, Excel provides an easier way to calculate loan payments using the payment (PMT) functionA built in Excel function that calculates loan payments. Inputs to the function include the loan amount (pv), the interest rate (rate), and the number of loan payments (nper).. In this chapter we will examine functions, how they differ from formulas, and how to use them in a spreadsheet. PMT or periodic payment is an inflow or outflow amount that occurs at each period of a financial stream.

## PMT Function Calculator – Excel Template

In essence, our Finance Calculator is the foundation for most of our Financial Calculators. It helps to think of it as an equivalent to the steam engine that was eventually used to power a wide variety of things such as the steamboat, railway locomotives, factories, and road vehicles. There can be no Mortgage Calculator, or Credit Card Calculator, or Auto Loan Calculator without the concept of the time value of money as explained by the Finance Calculator. As a matter of fact, our Investment Calculator is simply a rebranding of the Finance Calculator while everything underneath the hood is essentially the same. If your loan conditions are different from the defaults, then use the full form of PMT formula. By default, Excel display the result in the Currency format, rounded to 2 decimal places, highlighted in red and enclosed in parenthesis, as shown in the left part of the image below.
