Formula:
Percentage Value = (Part ÷ Whole) × 100
Example:
What is 25% of 200?
→ (25 ÷ 100) × 200 = 50
Formula:
Percentage = (Part ÷ Total) × 100
Example:
What percent is 50 of 200?
→ (50 ÷ 200) × 100 = 25%
To find the percentage change between two values:
Percentage Change = ((New − Old) ÷ Old) × 100
Example – Increase:
Old value: 100
New value: 125
→ ((125 − 100) ÷ 100) × 100 = 25% increase
Example – Decrease:
Old value: 100
New value: 80
→ ((80 − 100) ÷ 100) × 100 = −20% decrease
These formulas help you interpret trends and compare values.
Follow these simple steps:
This makes it easy to solve everyday percentage problems without manual math.
Here are some common real-world situations:
Original price: $80
Discount: 25%
→ Discount amount = (25 ÷ 100) × 80 = $20
Final price = $80 − $20 = $60
You scored 45 out of 60. What percentage is that?
→ (45 ÷ 60) × 100 = 75%
Last year sales: $50,000
This year sales: $60,000
Percentage increase = ((60,000 − 50,000) ÷ 50,000) × 100 = 20%
