Frequently Asked Questions

How does the Percentage Calculator work?

Our Percentage Calculator computes percentages based on your inputs. Enter a number and a percentage to find the percentage of that number, or input two numbers to calculate what percentage one is of the other.

What types of percentage calculations can I do?

You can calculate the percentage of a number (e.g., 20% of 50), the percentage one number is of another (e.g., 15 out of 60), or find the original number from a percentage increase/decrease.

Can it handle decimal percentages?

Yes, the calculator works with decimal percentages (e.g., 7.5%). Enter the decimal value, and it will compute the result accurately, rounding as needed for clarity.

How do I calculate percentage change?

To find percentage change, input the original value and the new value. The calculator subtracts the original from the new, divides by the original, and multiplies by 100 to give you the percentage increase or decrease.
