Percentage Calculator

Percentage = (Marks Obtained ÷ Total Marks) × 100. Example: 450 out of 600 = (450/600) × 100 = 75%. For multiple subjects, add all marks obtained, divide by total possible marks, multiply by 100.

Percentage Increase = ((New Value – Old Value) ÷ Old Value) × 100. Example: salary increased from ₹30,000 to ₹36,000 → ((36000–30000)/30000) × 100 = 20% increase.

X% of Y = (X/100) × Y. Example: 15% of 2,400 = (15/100) × 2400 = 360. This is useful for calculating discounts, GST, tips, or any proportional amount.

Percentage = (A ÷ B) × 100. Example: 45 is what % of 200? → (45/200) × 100 = 22.5%.
