Mastering Percentage Calculations

Percentages are one of the most fundamental math tools used in everyday personal finance, business, discounts, taxes (GST/TDS), exam scores, and salary hike negotiations. A percentage represents a number or ratio expressed as a fraction of 100.

Everyday Percentage Formulas

1. Percentage of a Number (X% of Y)

Result = (X / 100) × Y

Example: 18% GST on ₹5,000 product = (18 / 100) × 5,000 = ₹900.

2. Percentage Increase / Salary Hike

% Hike = ((New - Old) / Old) × 100

Example: Salary increased from ₹6 LPA to ₹7.5 LPA = ((7.5 - 6) / 6) × 100 = 25% hike.

Practical Everyday Scenarios

🏷️ Shopping Discount

A ₹2,400 jacket on 30% discount saves ₹720. You pay ₹1,680.

🎓 Exam Score %

Scoring 465 out of 600 marks = (465 / 600) × 100 = 77.5% aggregate.

📈 Investment Gain

Stock bought at ₹250 and sold at ₹310 = ((310 - 250) / 250) × 100 = 24% profit.

Frequently Asked Questions

How to calculate percentage?

To find X% of Y: (X/100) × Y. Example: 15% of 1000 = (15/100) × 1000 = 150. To find what % X is of Y: (X/Y) × 100. Example: 150 is what % of 1000? (150/1000) × 100 = 15%.

How to calculate percentage increase?

Percentage Increase = ((New Value - Old Value) / Old Value) × 100. Example: Price increased from ₹1000 to ₹1150. Increase = ((1150-1000)/1000) × 100 = 15%.

How to calculate percentage decrease?

Percentage Decrease = ((Old Value - New Value) / Old Value) × 100. Example: Price decreased from ₹1000 to ₹850. Decrease = ((1000-850)/1000) × 100 = 15%.

What is the difference between percentage and percentile?

Percentage is a fraction of 100 (15% = 15/100). Percentile is a measure in statistics indicating the value below which a percentage of data falls (90th percentile means 90% scored below you).

How to add/subtract percentages?

You cannot directly add percentages of different bases. Example: 10% of 100 (=10) + 20% of 200 (=40) = 50, not 30%. Convert to actual values first, then add/subtract.
