To make things easier, you can use a formula to calculate the percent change from 30 to 18 in one minute.

The old value is the starting value and may be theoretical or actual. Either way, it may be a correct or a starting point. To find the percent increase from 30 to 18, first determine which value is higher than the new one. Then, divide that value by the new one. Finally, divide the result by the old value. The new value will be the original value minus the old one. To calculate the percent increase from 30 to 18 in one minute, you must know the difference between the two values and then divide that difference by the new value.
