One of the most important and practical math skills is the ability to calculate % increase, which may be used in the classroom, on tests, and—most importantly—in the real world. Even though many students believe it to be challenging, learning how to calculate percent increases can be rather simple. Also, Percent Increase Calculator can be used to make the calculations easy.
This step-by-step guide will show you how to compute percent increases using a quick and efficient method and Percent Increase Calculator. Moreover, you can quickly and properly calculate % to correctly solve arithmetic problems if you can recall these steps and learn how to put them into practice.
Percent Definition
The mathematical sign for percent is%, and it is used to represent parts per hundred in mathematics.
For instance, 40% indicates 40 out of 100.
For instance, 20% denotes 20 of every 100. I
Further, if 20% of 200 students have an exam tomorrow, then 40 students in total have a test tomorrow under this criteria.
Percent Increase Definition
What does “% increase” mean now that you grasp the concept of percent?
The difference between the final and the starting numbers is what mathematicians refer to as the percent increase between two numbers. Moreover, percentage increases are always expressed as a percentage of the starting value.
Remember that percentage increases will be shown as percentages and contain the sign %.
The ending figure would be 50, and the starting number would be 20 if you had $20 at the beginning and $50 at the end of the week and wanted to calculate the percent gain.
Percent Increase Calculator Use
The Percent Increase Calculator calculates the percentage increase between two values.
To calculate the % increase, enter the initial and final values.
Calculating Percentage Increase
- Put The Starting Value and Ending Value In Writing.
Let’s take the case where your vehicle insurance premium suddenly increased. Further, these values should be noted:
- Before the hike, the cost of your vehicle insurance was $800. Moreover, this serves as the initial value.
- It now costs $950 due to the increase. Its final value is this.
- Determine The Size of The Increase.
Deduct the starting value from the ending value to determine how much it increased. Moreover, at this moment, we’re still using ordinary numbers, not a percentage.
- In this example, $950 less $800 equals a $150 increase.
- Divide The Result from The Initial Value.
The percentage is just a particular kind of fraction. A simple way to write “10 out of 100 cars,” for instance, is “10% of cars”. Further, the answer converts into a fraction that compares the two values by dividing it by the initial value.
- $150 divided by $800 equals 0.187 in our example.
- Multiply 100 to The Outcome.
Your previous result converts into a percentage using this.
- In our case, the final result is an 18.7% increase in vehicle insurance premiums (0.187 x 100).
Alternate Method
- Write Down The Initial Value And The End Value.
Let’s begin with a fresh illustration. In 1990, there were 5,800,000,000 people on the planet. Further, by 2015, there were 8,100,000,000 people.
- These difficulties with several zeroes have a trick. We can rephrase these as 5.8 and 8.1 billion instead of counting the zeros one by one.
- By The Starting Value, Divide The End Value.
This will demonstrate how much the final product has grown from the beginning.
- 8.1 billion / 5.8 billion = about 1.4.
- Because there were two significant digits in the original problem, we rounded to two significant digits.
- Multiply By 100.
You’ll be informed of the percentage difference between the two figures in this way. Your answer must always be more than 100 if the value increases.
- 1.4 x 100 = 140%. Accordingly, the world’s population in 2015 grew by 140% from 1990.
- Subtract 100.
“100%” is the size of the base value in this type of problem. We can get merely the percentage size of the increase by taking this out of our answer.
Population growth of 40% is equal to 140% − 100%.
- Starting value plus increase equals end value, hence this strategy works. Further, if we rewrite the equation, we obtain increase = end value – starting value.
Conclusion
Using the following three steps, you can determine the % increase given any two values:
Subtract the starting value from the end value to find the difference between the values.
Multiply the difference by the initial number. Decimalize the outcome.
Further, Multiplying by 100 is step three. Put the outcome in percentage form.
In addition to these steps, you can use Percent Increase Calculator to do the same.
