How is percent increase calculated?

The calculation of percent increase is based on determining how much a value has grown relative to its original amount. To find the percent increase, you subtract the original value from the new value, which gives you the absolute change. This change is then divided by the original value to find the increase relative to what it was initially. Finally, multiplying by 100 converts this ratio into a percentage.

Thus, the formula involves taking the difference between the new and original values, dividing that by the original value, and multiplying by 100% to express it as a percentage. This clear approach ensures that you understand both the actual change in value and how it relates to the original amount.
