The percentage increase calculator is a useful tool to calculate the increase from one value to another in terms of percentage of the original amount. Before using the calculator, you should understand how to calculate percent increase by using the percent increase formula. The upcoming sections will explain these concepts in further detail.
The percent increase formula is as follows:
Percent increase = [(new value - original value)/original value] * 100
An example using the formula is as follows. Suppose a $1,250 investment increased in value to $1,445 dollars in one year. What is the percent increase of the investment? To answer this, us the following steps.
Working out the problem by hand we get
[(1,445 - 1,250)/1,250] *100
(195/1,250) * 100
0.156 * 100
The percentage growth calculator is a great tool to check simple problems or solve more complex problems involve percent increase. The percentage calculator is also useful in this type of problem.
If you want to know how to calculate percent decrease, we follow a very similar process as percent increase. Notice the slight modification of the formula:
Percent decrease = [(original value - new value)/original value] * 100
Suppose we have the same investment value after one year of 1,445. A year later the value decreased to 1,300. The percent decrease would be calculated as follows:
[(1,445 - 1,300)/1,445] * 100
(145/1,445) * 100
0.10 * 100 = 10percent decrease
We learned how to calculate percent increase and percent decrease, but sometimes we just are interest in the change in percent without concern of increase or decrease. If that is the case, you can use the percent change calculator or the percentage difference calculator. A situation which this might occur would be an opinion poll to see if the percent of people who favor a particular political candidate differs from 50 percent.
