Frequently Asked Questions
How do I calculate a percentage of a number?
To find X% of Y, multiply Y by X and divide by 100. For example, 25% of 200 = 200 x 25 / 100 = 50.
How do I calculate percentage increase?
Percentage increase = Original x (1 + Percentage/100). For example, 100 increased by 20% = 100 x 1.20 = 120.
How do I calculate percentage change?
Percentage change = ((New Value - Original Value) / Original Value) x 100. A positive result means increase, negative means decrease.
