This tutorial will teach you how to calculate percentages in excel. Here, you will be using formulas to find basic percentages as well as the percentages of total and more. Using percentages is very relevant in various aspects of life whether in schools, restaurants or for calculating income taxes.

Say you were give a 25% in addition to your exams scores for a decent presentation. How much will you will you score in total? This is what the tutorial is going to explore with some few techniques which will efficiently calculate percentages using a basic formulae.

**The Basic Percentage Formulae**

Lets go back to history. The word “Per Cent” is derived from the latin word, per centum which means by the hundred. Do you remember in high school what it means? It meant a fraction of 100 which is calculated by dividing the numerator by the denominator and multiplying it by 100. The formulae goes this way, (Part/Whole)*100

For instance, if there are 50 oranges that belongs to you and you gave 20 to your friend, how much will you get percentage wise? It is a simple calculation which is 20/50*100. Your final answer will be 40%. That is how we are thought to calculate percentages in school without using the computer.

Using excel to calculate percentage will make work much easier as you only have to decide the formulae you use. The basic formulae for calculating percentages in excel goes part/total * percentage. But there is an easy way to go about it instead of multiplying it by 100. Lets look at this example, if you enter the formulae = B2/C2 in lets say cell D2 which will show in the formulae bar. Copy it down as many rows as you can then choose the percent style button found in Home > formulas > Choose the drop down list under formulae > click on percentage.

**If Parts of The Total Are In A Multiple Row**

For instance if you have the same product listed in the midst of other products, you can find its percentage as well as the total. In this case, you will use the SUMIF function to add up the numbers relating to that specific product. In using the sumif function in this situation, youmust add up all the numbers relating to the product and the divide by the total. The formulae goes this way;

`=SUMIF(range, criteria, sum_range) / total`

Column A contains all the product names whillst column B lists the quantities. Cell E1 lists the name of the product you are interested in whilst the total is in B10. The overall formulae will look like this: =sum(A2:A10,E1 B2:B10, )/$B$11

:

Also, you can put the name of the product directly into the formulae like this;

=SUMIF(A2:A1, ORANGES, B2:B10)/$B$11.
