How to use a financial calculator

But it is a matter of sorrow that most of the users do not know how to use a financial calculator properly. Some of them may have used it before but not regularly. That’s why they need to learn also. So in this article, I am going to show how to use a financial calculator. I am going use a Texas Instruments BA II Plus Professional Financial calculator for all examples. So if you are questing for how to use financial calculator ba ii plus, you are also at the right place.

## What is the financial calculator?

Okay, first things first. When this question emerges that what is a financial calculator? I have to clear it very early. The financial calculator can be called as a revolutionary device for the investing site. It is also known as a business calculator.

It can perform financial functions which are commonly needed for the business-related calculation. Bankers also use this calculator for finding loan or interest. It is also used for accounting, finance, real estate and other various works. So, the financial calculator is a very useful device for all commerce-related sectors.

## Getting started with turn ON and turn OFF

Press “ON/OFF” for turning on the calculator. When you turn on your calculator, those following things start automatically-

It returns to standard-calculator mode displayed with zero.

All worksheet and format for numbers, angular units remain unchanged since your last turning off.

If Automatic Power Down-(OPD) turns off the calculator, the calculator will start from exactly where you left. That means it will recover your data and store for you.

Press “ON/OFF” to turn off the calculator. When you turn off your calculator, all the displayed numbers and errors will be removed.

**Automatic Power Down**

**Automatic Power Down**This feature will turn off your calculator after 5 minutes of inactivity. When you turn on your calculator after this shutdown, you will find everything unchanged since you left.

**TVM and Amortization Worksheet Variables**

**TVM and Amortization Worksheet Variables**There is some Time Value for Money (TVM) and Amortization value in a financial calculator. You can find these variables in the first row of your calculator. Some most common variables are-

**N= Number of payments**

**I= Interest Rate Per Year or Month, or Yield/Return**

**PMT= Payment**

**FV= Future Value**

**PV= Present Value**

**P/Y= Number of Payments Per Year**

**END= End of Period Payments**

**BGN= Beginning of Period Payments**

**C/Y= Number of Compounding Periods per Year**

Among these variables, the most common 4 variables are N, I, PMT and PV. If you know any three values of these variables, you can easily find the unknown one. Let’s try an example based on these variables.

**Finding Payment Amount (PMT)**

**Finding Payment Amount (PMT)***** Suppose, you are planning to make a loan of $10,000, amortized over 10 years that means 120 monthly payments. The annual interest rate will be 10%.**

Now, there is a fact. When your annual interest rate is 10% and your payment method is going to be monthly, your annual interest must be reduced in a monthly process. Okay, most of the financial calculators will do this job automatically.

But not every calculator has the same function. If your calculator does not possess this function you have to divide 10 by 12 to get the monthly interest rate. It will be .83.

There is also an error related fact. Some calculator will show the error message if both Payments amount (PMT) and Present Value (PV) or loan amount remains positive. One of these variables must remain negative. I will suggest you keep incoming number (Cash In) positive and outgoing number (Cash Out) negative.

Now if your calculator is correctly programmed, let’s try to solve the problem. In this question, Present Value (PV) is $10,000. So put $10,000 in PV. As it is a monthly payment and for 10 years, so the Number of payments will be 120 as 10 years means 120 months.

So put 120 in N. Put .83 to I as .83 is the monthly payment rate. If everything has inserted correctly, the answer will show $132.15 for Monthly Payment (PMT).

The fact is very simple here. You have 4 variables-PMT, PV, N and I. If you create a table for these to solve a problem related these 4 particular functions, it is fundamental to know any 3 value of these variables. Only then, you can solve the unknown variable.

**Finding Future Value (FV)**

**Finding Future Value (FV)**Now then, let’s solve another problem related these functions. This time, we are going to find Future Value of an investment.

*** If you open the account with $5,000, how much will you have after 20 years? Your annual interest rate is .5%.**

In the beginning, clear all data from your calculator and set it to default settings. Now, enter the number of payments (N) 20. As your payment is going to be yearly and you are going deposit for twenty years. Set (I/Y) to .5 because your interest per year is .5%. Enter the beginning balance or Present Value (PV) $5,000. Calculate the problem.

The answer will be Future Value, FV= $5,524.48. That means after 20 years your account will be worth $5,524.48.

**Finding the Interest Rate (I/Y)**

**Finding the Interest Rate (I/Y)**The variable I/Y indicate the interest rate on your loan in every year. This rate will be multiplied by your loan amount. Let’s try another example-***If you make a monthly payment of $425.84 on a 30-year mortgage for $75,000, what is the interest rate on your mortgage?**

Set your calculator to default mode again. Here is a fact that I need to share at first. We are going to find yearly interest rate. But you have to pay it monthly that means in a monthly interest rate. So you have to use Payments per year (P/Y) variable.

As you are going to pay for every month set the Payments per Year (P/Y) to 12. Now return to standard mode. Enter the number of payments (N) to 360. Because it is a 30-year mortgage and every year means 12 months. So multiply 30x12=360 and this is the number of payment. Enter the loan amount (P/V) - $75,000.

Enter payment amount (PMT) - $425.84. Give a negative sign for this variable as I mentioned it earlier. As this is an outgoing value so this should be negative. Compute the interest rate.

The answer will be 5.5% interest rate every year.
