Lesson 5: Percentage Increase

Calculate percentage increases and growth rates.

📚 Percentage Increase

A percentage increase tells you how much a value has grown compared to its original amount.

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

Example: Price increased from $50 to $65

1
Find the difference: 65 - 50 = 15
2
Divide by original: 15 ÷ 50 = 0.3
3
Multiply by 100: 0.3 × 100 = 30% increase
