What This Tool Does
This tool covers the three percentage calculations people actually search for: finding a percentage of a number (like a discount), finding what percentage one number is of another (like a test score), and finding the percentage change between two numbers (like a price increase or a salary hike).
How to Use It
- Scroll to the calculator matching what you need — X% of Y, X is what % of Y, or % change from X to Y.
- Enter your numbers and press Calculate.
- The result appears instantly below the form.
Example
A shirt costs ₹1,200 and is 20% off. Use "20% of 1200" to find the discount amount is ₹240 — so the final price is ₹960. Or, if your salary went from ₹45,000 to ₹52,000, use the "% change" calculator to instantly see that's a 15.56% increase.
Frequently Asked Questions
What's the difference between percentage and percentage points?
A change from 20% to 25% is a 5 percentage point increase, but a 25% relative increase in the percentage itself — the two describe different things and are easy to mix up in news reporting and finance.
How do I calculate a discount using this tool?
Use the first calculator (X% of Y) with the discount percentage and original price to find the amount saved, then subtract that from the original price for your final cost.
Why is percentage change based on the starting number, not the ending one?
Percentage change is always measured relative to where you started, since that's the baseline being compared against — this is a standard convention in finance and statistics, and it's why a 50% drop followed by a 50% rise doesn't bring you back to where you started.
