## Percentage Calculator

**What is a Percentage Calculator?**

A **percentage calculator** is a way of expressing a number as a fraction of a cent, usually using the % sign.

Very common use in today’s world since it is found in statistics as in economics, the percentage is a notion which can induce many errors of reasoning.

Percentages are used in everyday life and are necessary to calculate, for example, the amount of a reduction, the evolution of an amount or share of representation of a group as a whole. This means, in some cases, calculate the number of individuals or objects if the total was increased to 100. Also, selected tutorials to learn how to calculate the percentage and their rates.

*Instructions: for many people the calculation of a percentage is not easy. These three very calculators simplify tasks. The first simply enter the desired percentage and the number from which it must be obtained. In the second calculator must enter two digits, the first of which is placed in relationship with the second; by clicking on “Calculate result” you will know what percentage it represents. In the third calculator, however, it is determined by the increase (or the decrease) in percentage terms between the first and the second digit.
Financial mathematical calculator that calculates the percentage difference between two numbers. So you can see what is decreased or increased in proportion the first number from the second. The percentage changes are useful and help people understand the changes in value over time. To use these tools, just enter the two numbers in the appropriate fields, and after a while you will see the% you were looking for.*

The application of a *percentage calculator* will allow you to define what is a rate based on basic amounts. For example, if you take a product that costs 50$ off taxes and VAT allocated is 20% then you can do a simple calculation to determine the final price, namely: (price x rate) 100. In our example, the calculation looks like this: (50 x 20) / 100 = 10. Therefore, the amount of VAT to 20% on a product that costs 50$ to 10$. This gives us a price including VAT (all taxes included) 60$ (50 + 10 = 60$).

**Calculate a percentage easily and quickly**

The percentages, we see much and all the time when we’ll buy and there are discounts or even on bills of electricity or phone. You probably know that the percentage is just a way to express a number. Indeed, it is all just a fraction of a cent to a number that is used when you want to represent a proportion of a set.

As it is widely used, it is important to know how to calculate percentage. If you want to *learn how to calculate percentage*, there are books or you can see on the net on specialized sites that publish courses to learn all the mathematical tricks that can be used in everyday life.

For those who don’t know, apply a *percentage calculator* is used to get the number of the portion of the total set. For example, if someone tells you that 10% of all of those present at the conference are women while there are 130 participants, you’ll calculate and know that only 13 women participating in the conference.

Just do a multiplication between the total number of participating and the result of the fraction of 10 per 100. What gives 130 multiplied by 0.1. During the sales, for example, the application of a **percentage formula** can turn in search of a fourth proportional to an equation. That is, the unknown factor of the equation would be the amount out of the total price of the product.

**The Percentage Difference Calculator**

The Percentage Calculator Grades called percentage changes when we go deeper in the economy and the calculations of interest rates there. Indeed, those who are in the field must learn how to *calculate percentage increase* and percentage reduction.

These are always used to find some value, but in taking in another way. Must be used with multipliers to calculator percentage by following this method of specialist. For example, if you have an increase of x %, what you have to do is multiply the value given by 1 + the fraction of x per cent. For a percentage of decrease, the multiplication must be made by 1 less the fraction of x by 100. In summary, this is how to calculate a percentage increase or decrease.

**The determination of a percentage**

The simple determination of a percentage formula can set the proportion in the total amount. For example, if there are people attending an event and you want to bring back the result to a percentage there are fairly *simple calculation methods*.

**Short about percentage:**

*Percentage is recorded using the% sign.*

* In order to transfer the interest in the shot, you need to remove the% sign and divide the number by 100.*

* To convert a decimal to a percentage, you multiply the fraction by 100 and add a% sign.*

* To convert common fractions into percentages, you must first convert it to a decimal fraction.*

* As you have seen, interest is closely linked to the common and decimal fractions. Therefore, it is worth remembering a few simple equations.*

* In everyday life, you need to know about the numerical relation of fractions and percents. Thus, half – 50%, a quarter – 25%, three-quarters – 75%, a fifth – 20%, and three fifths – 60%.*

For example, an event which has 200 people in total, and that includes 40 people aged between 18 and 25 years old. To know the percentage of people aged between 18 and 25 years old who participated in the event simply to apply a simple calculation: amount of the targeted category / amount total, or 40 / 200 = 0.2. This figure of 0.2 has only to be multiplied by 100, which gives us 20%.

Another *Percentage Formula* of calculation is in the search for the fourth proportional, which gives us (amount of category x 100) / total amount, that is, in our example: (40 x 100) / 200 = 4 000 / 200 = 20%.

In the calculation of a percentage it is possible, as the case may be, to get a number greater than 100%. This is particularly the case for the increase in the price of a product. For example, taking an article that cost the year last 60$, and which now costs 80$, the percentage increase is calculated as follows: new amount / former amount = 80 / 60 = 1.33. Knowing that 1.33 is equal to 133 / 100, then we can say that this article has increased by 133% in a year.

The determination of a percentage can have many uses in life in general, and particularly in our consumer habits that may need to appeal to a consumer credit, or even to *calculate the price of a sale item*, a discount, a discount.

This calculation is also very interesting to determine VAT (value added tax) that you pay on a product, especially for professionals who can recover this tax, or for individuals who can benefit from advantageous rates depending on the nature of the work performed. The **calculation of the percentage** is also essential for a person who wants to know the net amount of his salary on the basis of the gross amount. Let’s see together all possible applications to calculate a percentage.
