Percentage Calculator
Calculate percentage value, increase/decrease, and percent change instantly.
Overview
This page handles three common percentage tasks: finding what percentage one number is of another, calculating a percentage of a number, and finding percentage change between two values. These are common in finance, retail, analytics, and academic grading. All three cases are computed together from your inputs so you get all relevant results in one pass.
Common use cases
- Calculate discount amounts and sale prices in retail.
- Find score percentages for tests and assignments.
- Compute growth or decline rates in business metrics.
- Determine percentage composition in recipe or ingredient mixing.
Examples and notes
- 45 out of 60 is 75%. Enter 45 as value and 60 as total to get this.
- A 20% discount on ₹1,200 gives ₹240 off — enter 1200 as base and 20 as percent.
- Revenue grew from ₹50,000 to ₹62,000 — that is a 24% increase.
Important note
For financial reporting, always round values according to jurisdiction-specific accounting rules rather than using raw calculator output.
