To increase a number by a certain percent, multiply it by (1 + n/100). For example, to increase a number by 15 percent, multiply it by (1 + 15/100), or 1.15. To decrease a number by 15 percent, multiply it by (1 - 15/100), or 0.85.

Percentage change: 25.0% increase.
To calculate the percent increase, we need to find the difference between the two numbers and then divide it by the original value. The difference between 2000 and 1250 is 750. To find the percent increase, we divide the difference by 1250 and multiply by 100. So the percent increase is (750 / 1250) * 100 = 60%.
Subtract the two numbers and divide by the oldest or beginning number and move the decimal to change to a percent. If it goes down it is decrease and up for increase.
16 to 40 is a 150% increase.
