Percentage Calculator FAQ
What calculations can I perform?
Three types: "What is X% of Y?" (e.g., 20% of 500 = 100), "X is what % of Y?" (e.g., 25 is 12.5% of 200), and "Percentage change from X to Y" (e.g., 50 to 75 = +50%).
How is percentage change calculated?
Percentage change = ((New Value - Old Value) / |Old Value|) × 100. A positive result means increase, negative means decrease.
Can I calculate discounts with this?
Yes! Use "What is X% of Y?" to find the discount amount. For example, "What is 30% of 1000?" gives you 300 (the discount), so the sale price is 700.
Does it handle decimal percentages?
Yes, you can enter decimal values like 7.5%, 12.25%, or any precision you need. Results are shown with up to 2 decimal places.
