Frequently Asked Questions
Subtract the original value from the new value to find the absolute difference. Divide that difference by the original value, and multiply by 100 to get the percentage increase.
The standard computational formula is (X / Y) * 100. For example, to find out what percent 20 is of 50, you compute (20 / 50) * 100, which equals 40%.
Mathematically, the commutative property of multiplication allows percentages to be flipped. For example, 8% of 50 is the exact same numeric value as 50% of 8 (both equal 4).
