Percentage Formulas

Result = (Percentage ÷ 100) × Number

Example: 25% of 200 = (25 ÷ 100) × 200 = 50

Change% = ((New - Original) ÷ Original) × 100

Example: 100 to 120 = ((120 - 100) ÷ 100) × 100 = 20%

Result = Number + (Number × Percentage ÷ 100)

Example: 100 + 20% = 100 + (100 × 20 ÷ 100) = 120

Percentage = (Number ÷ Total) × 100

Example: 25 of 100 = (25 ÷ 100) × 100 = 25%
