🧐 Frequently Asked Questions

Q. How do I calculate a discount price?

A. Use the "X% of Y" tab. For example, for "30% OFF", calculate the remaining "70%" to find the final price. Alternatively, check out our dedicated Discount Calculator tool.

A. Yes. For example, if sales go from $100 to $300, the change rate is "+200%" (meaning it increased by 2 times the original amount).

📚 Trivia

Do you know the difference between "Percent" and "Percentage Points"? If an approval rating rises from 50% to 60%, saying it "rose 10%" is technically ambiguous (since 10% of 50 is 5). The correct term is "rose 10 percentage points". Keep an ear out for this in financial news!
