Formula & Mechanics
Percentage Increase = ((New Value - Original Value) / Original Value) × 100
Subtract the original value from the new value to determine absolute change. Divide that difference by the original baseline value, then multiply by 100.
Worked Step-by-Step Example
Scenario: A product price goes up from $80 to $100.
- Calculate absolute increase: 100 - 80 = 20
- Divide by original baseline: 20 ÷ 80 = 0.25
- Multiply by 100: 0.25 × 100 = 25%
The price increased by 25%.
Frequently Asked Questions
Why must we divide by the original value rather than the new value?
Growth is always measured against where you started. Dividing by the original baseline ensures the metric reflects true relative expansion.
