## How to Calculate Percentage?

Percentage calculation is a mathematical operation used to find a certain percentage of a value. A simple ratio calculation is usually used to calculate the percentage of a value.

The following steps are generally followed to calculate percentages:

- Determine the value you want to express as a percentage.
- Determine the percentage rate.
- Multiply the value by the percentage.
- Divide the result by 100 to find the percentage value.

For example, you can follow these steps to calculate 20% of the number 80:

- Determine the value 80.
- Determine the percentage rate (20%).
- Multiply 80 by 0.20: 80 * 0.20 = 16.
- Divide the result by 100 to find the percentage value: 16 / 100 = 0.16 or 16%.

Percentage calculation is used in many areas such as price discounts, interest rates, tax rates. This is a common method for expressing and comparing values in percentages.

### What is a Percentage?

A percentage is a fractional ratio of an integer divided by 100. It is usually denoted by the percent (%) sign and is used to express a certain proportion of a value.

Percentage is often used to express parts of a whole. For example, if the discount rate for a product is 30%, it means that the price of that product has been reduced by 30% of its original price.

The concept of percentage is important in many areas, from financial calculations to statistical analysis. Percentages are used to evaluate price changes, growth rates, tax rates, etc.

In summary, percentage is an important mathematical concept used to express how much of a whole a value represents.

### Percentage Calculation Formula

Percentage calculation is done with a simple mathematical formula used to find a certain percentage of a value. The percentage calculation formula is as follows:

Percentage Value = ( Percentage Ratio x Base Value / 100)

In this formula

- Percentage Value: the percentage value to be calculated
- Percentage Rate: the percentage amount to be calculated
- Base Value: represents the initial value from which the percentage will be calculated.

The percentage calculation formula is used to find the expression of a value as a percentage. For example, if the discount rate of a product is 20% and the price of the product is 100 USD, you can use this formula to find the price after the discount:

Price After Discount = ( 20 x 100 / 100 ) = 20

In this case, the price of the product after the discount would be 80 USD.

The percentage calculation formula has a wide range of uses, from financial transactions to business calculations, and allows you to quickly and easily find the expression of a value as a percentage.

### Percentage Calculation Methods

Percentage calculation can be performed by different methods used to find a certain percentage of a value. Here are some commonly used percentage calculation methods:

**Ratio Calculation Method:**In this method, the percentage rate is calculated directly from the base value. For example, if a product has a discount rate of 20%, you can find the discounted price by subtracting this rate directly from the base value.**Discount Percentage Calculation Method:**In this method, when the post-discount price and the original price are known, the discount percentage is calculated directly. For example, if the post-discount price of a product is 80 USD and the original price is 100 USD, the discount percentage (20%) can be found directly.**Increase Percentage Calculation Method:**In this method, when the amount of increase and the original value are known, the percentage increase is calculated directly. For example, if a company’s revenue was 100,000 USD last year and 120,000 USD this year, the percentage increase (20%) can be found directly.

Which of these methods to use depends on how the calculation is done and what information you have. Percentage calculation methods have a wide range of uses, from financial analysis to business calculations, and can be chosen to suit different situations.
