If you want to find out what would be the percentage for a given integer out of another non-zero integer, then this online percentage calculator is the ideal tool. It quickly calculates the percentage value and is ideal for math students who are studying the topic of Percentages.

## How to use the percentage calculator tool

**Step 1 :** Enter the first number

**Step 2 :** Enter the second number which will ideally be more than the first number

**Step 3 :** Click on the Calculate button to find first number is what % of the second number.

## Percentage Calculation Formula

Percentage (%) = \left(\frac{{\text{First number}}}{{\text{Second number}}}\right) \times 100

So, if the first number you entered is 50 and the second number entered is 80, then the percentage is calculated as follows:

Percentage(%) = \left(\frac{50}{80}\right) \times 100

Percentage(%) = 0.625\times 100

Percentage(%) = 62.5\%

A percentage calculator is a tool that helps you calculate percentages. It can be used to solve various problems related to percentages, including calculating the percentage of a number, finding the percentage increase or decrease, and calculating the percentage of a percentage. In this article, we will explore what a percentage calculator is, how it works, and how you can use it to solve problems.

## What is Percentage Calculator?

A percentage calculator is a tool that helps you calculate percentages. It can be used to perform various percentage-related calculations, such as finding the percentage of a number, calculating percentage increase or decrease, and calculating the percentage of a percentage.

## How does Percentage Calculator work?

A percentage calculator uses a simple formula to calculate percentages. The formula is:

Percentage =\left(\frac{\text{Part}}{\text{Whole}}\right)\times 100

where Part is the part of the whole that you want to find the percentage of, and Whole is the total amount.

For example, let’s say you want to find the percentage of 40 out of 100. To do this, you need to use the formula:

Percentage =\left(\frac{\text{Part}}{\text{Whole}}\right)\times 100

Here, Part is 40, and Whole is 100. So the calculation looks like this:

Percentage =\left(\frac{40}{100}\right)\times 100

Percentage =0.4\times 100

Percentage =40\%

Therefore, the percentage of 40 out of 100 is 40\%.

Uses of Percentage Calculator

Percentage calculator is a useful tool in many fields, including finance, business, education, and more. Here are some examples of how it can be used:

### 1. Finding discounts

Percentage calculator can be used to find discounts. For example, if an item is originally priced at $100 and is on sale for 20% off, you can use the percentage calculator to find the discounted price. To do this, you need to find 20% of $100, which is $20. Then, subtract the $20 from the original price of $100 to get the discounted price of $80.

### 2. Calculating tax

Percentage calculator can be used to calculate tax. For example, if the tax rate is 6% and the purchase price is $50, you can use the percentage calculator to find the amount of tax. To do this, you need to find 6% of $50, which is $3. Then, add the $3 to the purchase price of $50 to get the total price of $53.

### 3. Estimating growth rates

Percentage calculator can be used to estimate growth rates. For example, if a company had a revenue of $1 million last year and $1.2 million this year, you can use the percentage calculator to find the growth rate. To do this, you need to find the percentage increase in revenue. To do this, you can use the formula:

Percentage Increase = \left( \frac{{\text{New Value} - \text{Old Value}}}{{\text{Old Value}}} \right) \times 100

Here, the New Value is $1.2 million, and the Old Value is $1 million. So the calculation looks like this:

Percentage Increase = \left( \frac{{\text{1.2 million} - \text{1 million}}}{{\text{1 million}}} \right) \times 100

Percentage Increase = \left( \frac{\text{0.2 million}}{{\text{1 million}}} \right) \times 100

Percentage Increase = 20\%

Therefore, the growth rate is 20\%

### 4. Analyzing data

Percentage calculator can be used to analyze data. For example, if you have data on the number of male and female employees in a company, you can use the percentage calculator to find the percentage of male and female employees. This can help you understand the diversity of the workforce and identify areas where you need to improve.
