This calculator helps to calculate the percentage of debt one must pay if they have \$5,000 and \$2,000 debt that total to \$7,000.

### Use

10 is the part, 40 is the whole, and 25 is the percentage. In the math world, working out percentages usually means that one of those terms is missing and you need to find it. If the question is "What percentage of 40 is 10?" you have the part (10) and the whole (40), so the omitted term is the percentage. If the question is "What is 25 percent of 40?" you have the percentage (25) and the whole (40), so the missing term is the part. Using the same logic, if the question is "10 is 25 percent of what?" the missing term is the whole.This percentage calculator is a tool that lets you do a simple calculation: what percent of X is Y? The tool is pretty straightforward. All you need to do is fill in two fields, and the third one will be calculated for you automatically. This method will allow you to answer the question of how to find a percentage of two numbers. Furthermore, our percentage calculator also allows you to perform calculations in the opposite way, i.e., how to find a percentage of a number. Try entering various values into the different fields and see how quick and easy-to-use this handy tool is. Is only knowing how to get a percentage of a number is not enough for you? If you are looking for more extensive calculations, hit the advanced mode button under the calculator.

Other than being helpful with learning percentages and fractions, this tool is useful in many different situations. You can find percentages in almost every aspect of your life! Anyone who has ever been to the shopping mall has surely seen dozens of signs with a large percentage symbol saying "discount!". And this is only one of many other examples of percentages. They frequently appear, e.g., in finance where we used them to find an amount of income tax or sales tax, or in health to express what is your body fat. Keep reading if you would like to see how to find a percentage of something, what the percentage formula is, and the applications of percentages in other areas of life, like statistics or physics. Percentage points (or percent points) are a rather tricky beast. We use it all the time even if we don't know it - and in these situations, we often incorrectly say percent instead of a percentage point. Once you read this section, you will know how to do it properly and be annoyed for the rest of your life (because other people will keep making the mistake). We can already say that percentage points play an essential role in statistics, e.g., in the normal distribution, binomial distribution, or to find the confidence interval for a sample of data (confidence level is usually at 95 percentage points).

### Example

Percentages are sometimes better at expressing various quantities than decimal fractions in chemistry or physics. For example, it is much convenient to say that percentage concentration of a specific substance is 15.7% than that there are 18.66 grams of substance in 118.66 grams of solution (like in an example in percentage concentration calculator). Another example is efficiency (or its special case - Carnot efficiency). Is it better to say that a car engine works with an efficiency of 20% or that it produces an energy output of 0.2 kWh from the input energy of 1 kWh? What do you think? We are sure that you're already well aware that knowing how to get a percentage of a number is a valuable ability. To do percentages on a calculator using the percentage button, enter the percentage times the original number. For example, if you wanted to give a waiter a 20% tip on your \$50 order, you would enter 20 and hit the percentage button to get 20%. Then you would hit the multiplication button, enter 50, and hit the equals button to find that 20% of \$50 is \$10. Read more to learn how to find percentages without using the percentage button!

The percentage increase calculator above computes an increase or decrease of a specific percentage of the input number. It basically involves converting a percent into its decimal equivalent, and either subtracting (decrease) or adding (increase) the decimal equivalent from and to 1, respectively. Multiplying the original number by this value will result in either an increase or decrease of the number by the given percent. Refer to the example below for clarification.
