Mathematical formulas and explanations
Basic percentage
Formula: Result = Base value × (Percentage ÷ 100)
Example: 100 × (15 ÷ 100) = 15
Percentage increase
Formula: Result = Base value × (1 + Percentage ÷ 100)
Example: 100 × (1 + 15 ÷ 100) = 115
Percentage decrease
Formula: Result = Base value × (1 – Percentage ÷ 100)
Example: 100 × (1 – 15 ÷ 100) = 85
Percentage difference
Formula: Percentage = ((New value – Old value) ÷ Old value) × 100
Example: ((120 – 100) ÷ 100) × 100 = 20%
Percentage ratio
Formula: Percentage = (Part ÷ Whole) × 100
Example: (15 ÷ 100) × 100 = 15%
