A guide on some commonly used calculators. These include three of the Basic Percentage Calculators, the Percentage Change Calculator and Percentage Difference Calculator. At the bottom of the page you will see some real life examples of how and when to use them.
Decimal to Percentage
What is 0.33333 as a percentage?
Answer: What is 0.33333 as a percentage? = 33.333%
There are some equations that don’t really need a calculator. Like this Decimal to Percent. Either multiply it by 100 or just move the decimal to the right by two spaces.
In this example or query as to what is 0.3333 as percentage we can either multiply it by 100 and get 33.333% or we can just move the decimal two places to the right and add a percentage sign at the end. Either way, we get the same result which is 33.333%.
1. Basic Calculator: What percentage is 150 out of 200?
Answer: What percentage is 150 out 200 = 75%
The first basic percentage calculator below will calculate the percentage between two numbers. Otherwise known as a 2 number percentage calculator.
For example: What percentage is 150 out of 200 = 75%
or lets word one differently: What percentage of 200 is 50 = 25%
2. Basic Calculator – What is 25% of 200?
Answer: 25% of 200 = 50.
The second basic percentage below calculator will calculate whatever percentage you want of a certain number.
3. Basic Calculator – 120 is 50% of What?
Answer: 120 is 50% of WHAT? = 240
The third basic percentage below calculator will calculate what a cetain percentage is of a specific value.
4. Percentage CHANGE Calculator (Increase / Decrease)
The percentage of change calculator below will calculate the percentage of decrease or increase between two numbers. Its purpose is to measure change. It typically has an old number and a new number and there is a context between the two.
For example: A town has 20,000 residents. Next year it will have 30,000 residents.
Answer: The percentage increase it will have= 50%
5. Percentage DIFFERENCE Calculator
This is not the same as the percentage of change. Its purpose is to measure the difference, not the change.
For example: Jane is 15 years old and Alex is 20 years old. The difference in their age is 5 years.
Answer: The percentage difference of their ages = 28.57%
Many of your business figures will come down to percentages—a straightforward way to calculate and understand numbers. From promotional offers on your product or service or even down to the bottom line on your financial statements, percentages are everyday numbers that your business will have.
To calculate percentages, you need to understand these specific mathematical calculations and have a great memory to keep practising them.
I progressed to the point of arranging them into formulas on an Excel sheet. However, the process became overwhelming as I found myself creating multiple sheets for specific variables or areas that necessitated calculation. For instance, there was one sheet dedicated to promotional discounts, another for profits, and additional sheets for items such as Cost of Goods, Salaries, and so forth.
I found myself constantly looking for the formula I needed and kept punching numbers into a calculator, only to discover I was multiplying and dividing things the wrong way around – oh boy, the crankiness started to set in.
There had to be a better way! A method that was done once and for all. So I developed some percentage calculators and opened them up whenever I had a task. I have saved myself an enormous amount of time and crankiness! If you are a traveller like me and accumulate miles or points to travel, then you want to visit my miles redemption calculator which gives you a good idea of value when spending miles on tickets.
They are excellent for business, but they are also useful whenever you need to calculate a percentage of any number or between numbers.
Real-Life Examples of Percentage Calculators
Here are some real-life examples of when and how to use them.
Basic Percentage Calculator 1:
Let’s say you want to give your customer $30 off the running shoes which cost $200. But you need a percentage. You enter 200 and 30 and the percentage is 15%. This is the percentage of discount your customer will receive.
Basic Percentage Calculator 2:
Let’s say you are running a promotion. You sell a pair of running shoes for $200. You’re running a promotion of 25%.
Enter 25% of 200, and the amount that comes off the running shoes is $50.
This is the discount you are offering to your customer.
Basic Percentage Calculator 3:
Let’s say you buy a pair of shoes that were reduced by 50% to $120. You are looking to find the following: $120 is 50% of What? Your answer is $240
Percentage of Change Calculator:
Let’s look at retail prices.
I am selling a T-shirt for $30 and now would like to increase it to $45. That is an increase of $15. My percentage change is 50%.
I am selling shoes for $120 and now would like to reduce them to $90. That is a decrease of $30. My percentage change is -25%
Percentage of Difference Calculator:
Let’s talk about staff salaries.
Jack earns $80,000 per year.
Mark earns $95,000 per year.
I want to find the difference between the two. I know it is $15,000. But what does that translate to in percentage?
The result I get is 17.14%. This is the difference between Mark’s and Jack’s Salaries.
Formulas
Interested in the formulas? Here they are:
Basic Percentage Calculator 1 Formula:
(formula used is 50 / 200 = 0.25 *100) = 25%
Basic Percentage Calculator 2 – Formula:
25% of 200 = 50 (formula used is 0.25 x 200 = 50)
Basic Percentage Calculator 3 Formula:
(formula used is 120 / 50 = 2.40*100) = 240
Value 1 is 150
Value 2 is 200
Value 2 minus Value 1: 200 – 150 = 50
Divide it by Value 1, which is 200, and it = 0.33333
Then multiply it by 100 to get your percentage = 0.3333*100 = 33.33%
(We see an increase in percentage which means that 200 is a 33.33% increase of 150)
Now let’s try it the other way around.
Value 1 is 200
Value 2 is 150
Value 2 minus Value 1 = 150 – 200 = -50
Divide it by Value 1, which is 200, and it = -0.25
Then multiply it by 100 to get your percentage = –0.25*100 = -25%
(We see a decrease in percentage which means that 150 is a 25% decrease of 200)
Percentage Difference Formula:
Value 1 is 150
Value 2 is 200
This is calculated using the following formula:
- Finding the absolute difference between the two numbers which in this case is 50
- Finding the average between the two numbers which in this case is 150+200/2 = 175
- Divide the absolute difference by the average (50/175) = 0.285
- Multiply it by 100 to get to a percentage = 28.57%
