Percentage Calculation Types
Percentage of a Number
Calculate what percentage of a number equals a specific value.
X% of Y = (X/100) × Y
Example: 25% of 200 = 0.25 × 200 = 50
Percentage Change
Calculate the percentage increase or decrease between two values.
% Change = ((New - Original) / |Original|) × 100

X is what % of Y
Calculate what percentage one value is of another.
X is (X/Y) × 100% of Y
Example: 25 is (25/100) × 100 = 25% of 100

% to Reach = ((Target - Current) / Current) × 100
