Frequently Asked Questions
What types of percentage calculations can I perform?
Our calculator supports multiple percentage calculations: finding a percentage of a number (X% of Y), calculating what percentage one number is of another (X is what % of Y), and determining values after percentage increases or decreases.
How accurate are the calculations?
All calculations are performed with high precision and rounded to 2 decimal places in the display for clarity. This ensures accurate results while maintaining readability.
Can I calculate percentage differences?
Yes, you can calculate the percentage difference between two numbers. The calculator will show both the absolute difference and the percentage change, indicating whether it's an increase or decrease.
How do I calculate a percentage increase?
Enter your starting value and the percentage increase. The calculator will show the final value after applying the increase. For example, a 10% increase on 100 would give you 110.
Can I use negative percentages?
While you can't enter negative percentages directly, you can use the decrease option when calculating percentage changes. This achieves the same result as using negative percentages.
