To use the percentage calculator you must select from the menu the formula you want to calculate and after entering the corresponding values in the input fields. You also have a description of the formula that will help you select the correct formula.
The most used formula for finding the percentages is: number × percent / 100. Consider the following example: Salary is 2100 and tax is 16%. What is the tax paid? If we apply the formula calculation percentage will result 2100 × 16/100 = 336. To abbreviate the percentage we will use the sign percentage (%).
Fractions are often evaluated as a percentage. The mathematical formula for calculating the percentage is very simple. Ex : There are 30 students in a class, 10 of whom are learning Finnish and 20 are learning German. What percentage of students learn Finnish? We have the following ratio 10/30 = 33%.
To determine the percentage, multiply by 100.
