Another handy tip is to use brackets when doing multiple operations. For instance, if you want to calculate a 20% discount on an item that costs $50 and then add sales tax at a rate of 8%, here’s what you need to do: first, calculate the discount by entering “50 x 20% =”. Then, subtract that amount from the original price by entering “50 - (50 x 20%) =”. Finally, add sales tax by entering “(50 - (50 x 20%)) x 8% +”. This will give you the final price of the item, which should be about $44.80.
As you can see, performing percentage calculations on a calculator is not as difficult as you may have thought. However, make sure to double-check your inputs and outputs to ensure accuracy.

Introduction: Understanding the Basics of Percentages
Calculating percentages is a fundamental skill that is often required in various fields such as finance, mathematics, and even everyday life. Whether you need to find a discount, calculate interest, or determine percentage change, having a good understanding of how to use a calculator for percentage calculations can be incredibly useful. In this guide, we will walk you through the step-by-step process of using a calculator to perform percentage calculations, making it easy for you to obtain accurate results with minimal effort.
Step 1: Press the On button to power on the calculator.
The first step in using a calculator for percentage calculations is to ensure that it is turned on. Locate the On button on your calculator and press it to power it up. This simple action will prepare the calculator for the calculations you are about to perform.
Step 2: Enter the original value or number for which you want to find the percentage.
Once your calculator is turned on, you can proceed to enter the original value or number that you wish to find the percentage of. This value could represent anything from a total amount to a quantity or a measurement. Make sure to enter the number accurately, as any errors at this stage will result in incorrect calculations.
Step 3: Press the % button to signify that you want to calculate a percentage.
After entering the original value, it is important to indicate to the calculator that you intend to calculate a percentage. To do this, locate the % button on your calculator and press it. This button is typically labeled with the percentage symbol (%), and pressing it will let the calculator know that you are performing a percentage calculation.
Step 4: Enter the percentage value you wish to calculate (e.g., 10%).
With the % button pressed, you can now enter the specific percentage value that you want to calculate. For example, if you want to find 10% of the original value, enter 10 on your calculator. Ensure that you enter the percentage value accurately, as any mistakes at this stage will lead to incorrect results.
Step 5: Press the = button to obtain the calculated percentage.
Once you have entered the desired percentage value, it's time to obtain the calculated percentage. Press the = button on your calculator, which is typically located at the bottom or side of the keypad. This button signifies that you have finished entering the necessary values and are ready to receive the result of your percentage calculation.
Step 6: Read the result displayed on the calculator's screen, which will show you the percentage value you were seeking.
After pressing the = button, the calculator will display the calculated percentage on its screen. Take a moment to read the result carefully, as it will show you the exact percentage value that you were seeking. This value will be based on the original number you entered and the percentage you specified.
Step 7: If necessary, round the calculated percentage to the desired number of decimal places.
In some cases, you may need to round the calculated percentage to a specific number of decimal places. For example, if you are dealing with financial calculations, you may require a certain level of precision. To round the calculated percentage, locate the appropriate rounding function on your calculator, which is often labeled with a symbol similar to Rnd or Round. Press this button and follow the on-screen prompts to round the result to the desired number of decimal places.
Step 8: To calculate backward from a percentage, enter the percentage value you have and press the %, followed by the = button for the original value.
Calculating backward from a percentage is also a useful skill that can be accomplished using a calculator. To do this, simply enter the known percentage value followed by the % button. Then, press the = button to obtain the original value. This method can be particularly helpful when determining the original price before a discount or finding the initial quantity after a decrease.
Conclusion: By following these simple steps, you can easily perform percentage calculations on your calculator, saving you time and effort.

Story: How To Do Percentage On Calculator
Once upon a time, in a small town, lived a young girl named Lily who was struggling with math. She had always found percentages to be particularly challenging. Determined to overcome her difficulties, she sought the help of her teacher, Mr. Johnson.
Mr. Johnson's Explanation
Mr. Johnson was known for his ability to simplify complex concepts and explain them in a way that everyone could understand. He decided to teach Lily how to calculate percentages using a calculator.
Step 1: Understanding Percentages
- Mr. Johnson began by explaining that percentages are a way of expressing a fraction of 100. For example, 50% is equal to 50 out of 100.
- He emphasized that percentages can be used to compare quantities or calculate discounts, among other things.
Step 2: Using a Calculator
- Mr. Johnson showed Lily how to use her calculator to calculate percentages.
- He explained that most calculators have a % button, which allows you to input the percentage directly.
- For example, to calculate 30% of 200, Lily needed to enter 200, followed by the % button, and then 30. The result, 60, would then be displayed on the calculator screen.
Step 3: Calculating Percentages Manually
- To reinforce her understanding, Mr. Johnson also taught Lily how to calculate percentages manually.
- He explained that to find a certain percentage of a number, you need to divide the percentage by 100 and then multiply it by the number.
- For example, to calculate 20% of 150 manually, Lily would divide 20 by 100 to get 0.2. Then she would multiply 0.2 by 150 to get the result of 30.
Lily's Progress
Thanks to Mr. Johnson's patient explanations and guidance, Lily soon became more comfortable with calculating percentages on her calculator. She practiced using both the direct input method and the manual calculation method until she could quickly and accurately determine percentages.
