What is a Percentage?

A percentage (represented by the symbol %) is a dimensionless ratio or number expressed as a fraction of 100. It is a highly standard way to compare ratios, express proportions, calculate interest rates, show retail discounts, and track performance changes in fields like finance, engineering, and statistics.

Percentage Formulas Used

Depending on the calculation mode, the mathematical formula differs:

• Percentage Value: To find X% of Y: Value = (X / 100) * Y
• Find Percentage: To find what % X is of Y: Percentage = (X / Y) * 100
• Percentage Change: To find % increase or decrease from X to Y: Change % = ((Y - X) / X) * 100

Percentage Calculation Examples

• Retail Discount: If a shirt costs ₹1,500 and is on a 20% sale: Discount value = (20 / 100) * 1,500 = ₹300. Net price = ₹1,200.
• Test Scores: If a student scores 45 out of 60 marks: Percentage = (45 / 60) * 100 = 75%.
• Salary Hike: If your salary increases from ₹50,000 to ₹55,000: Hike % = ((55,000 - 50,000) / 50,000) * 100 = 10% raise.
