In this tutorial, you will lean a quick way to calculate percentages in Excel, find the basic percentage formula and a few more formulas for calculating percentage increase, percent of total and more.Calculating percentage is useful in many areas of life, whether it is restaurant tipping, reseller commission, your income tax or interest rate. Say, you've been lucky enough to get a 25% off promotion code on a new plasma TV. Is this a good deal?
The GST is a broad-based tax of 10% on the supply of most goods, services and anything else consumed in Australia. Since Goods and Services Tax was introduced in 2000, thousands of Australians have to calculate the amount of GST to add to the price of goods or services or calculate how much GST is included in the price to claim tax credits for any GST included in the price of goods, services.
And how much will you eventually have to pay?In this tutorial, we are going to explore a few techniques that will help you efficiently calculate percent in Excel and learn the basic percentage formulas that will take the guesswork out of your calculations.Percentage basicsThe term 'per cent' is derived from the Latin per centum, meaning 'by the hundred'. As you probably remember from high school math class, a percentage is a fraction of 100 that is calculated by dividing the numerator by the denominator and multiplying the result by 100.The basic percentage formula is as follows. (Part/Whole).100 = PercentageFor example, if you had 20 apples and you gave 5 to your friends, how much did you give, percentage wise?
By performing a simple calculation =5/20.100 you get the answer - 25%.This is how you normally calculate percentages in school and everyday life. Computing percentage in Microsoft Excel is even easier since Excel performs some operations for you automatically, in the background.Regrettably, there is no universal Excel formula for percentage that would cover all possible scenarios. If you ask someone 'Which percent formula do I use to get the result I want?' , most likely, you will get an answer like 'Well, that depends on what exactly result you want to achieve.' So, let me show you a few simple formulas for calculating a percent in Excel such as a percentage increase formula, a formula to get percentages of a total and more. Basic Excel percentage formulaThe basic formula to calculate percentage in Excel is this.
Part/Total = PercentageIf you compare it to the basic, you will notice that Excel's percentage formula lacks the.100 part. When calculating a percent in Excel, you do not have to multiply the resulting fraction by 100 since Excel does this automatically when the percentage format is applied to a cell.And now, let's see how you can use the Excel percentage formula on real-life data. Suppose, you have the number of ' Ordered items' in column B and ' Delivered items' in column C. To make the denominator an absolute reference, either type the dollar sign ($) manually or click the cell reference in the formula bar and press F4.The screenshot below demonstrates the results returned by the formula, the Percentages of Total column is formatted as percentage with 2 decimal places showing.Example 2. (New Value - Old Value) / Old ValueAnd now, let's see how you can use this percentage change formula (aka Excel percentage increase formula) in your spreadsheets. Calculating percent change between 2 columnsSuppose that you have the last month prices in column B and this month prices in column C. Then you can enter the following formula in cell D2 to calculate percentage change in your Excel sheet:=(C2-B2)/B2This percent change formula calculates the percentage increase / decrease in this month (column C) comparted to last month (column B).After copying the formula to other rows, remember to click the Percent Style button on the ribbon to and you will get a result similar to what you see in the screenshot below.
In this example, positive percentages that show percentage increase are formatted in usual black, while the negative percentages (percent decrease) are formatted in red by using the technique explained in.Example 2. Calculating percentage change between rowsIn case you have one column of numbers, say column C that lists weekly or monthly sales, you can calculate percentage change using this formula:=(C3-C2)/C2Where C2 is the 1 st and C3 is the 2 nd cell with data. Please pay attention that you should skip the first row with data and put your Excel percentage formula into the 2 nd cell, which is D3 in this example.After applying the percent format to the column with the percent change formula, you will get the following result:If you want to calculate percentage change compared to a certain cell, then you need to fix the reference to that cell by using the absolute cell reference with the $ sign, e.g. $C$2.For instance, here is the Excel percentage change formula that calculates the percent increase / decrease for each month compared to January (C2):=(C3-$C$2)/$C$2When you drag the formula down to copy it to other cells, the absolute reference ($C$2) will stay the same, while the relative reference (C3) will change to C4, C5 and so on.Calculating amount and total by percentageAs you've just seen, calculating percentages in Excel is easy, and so is calculating amounts and totals if you know the percentage.
Calculate amount by total and percentageSuppose you are buying a new laptop for $950 and they charge 11% VAT on this purchase. The question is - how much do you have to pay on top of the net price? In other words, what is 11% of $950?The following formula will help. Total.
Percentage = AmountAssuming that the total value is in cell A2 and percent in B2, the above formula turns into a simple =A2.B2 and returns 104.50.Remember, when you type a number followed by the percent sign (%) in Excel, the number is interpreted as a hundredth of its value. For example, 11% is actually stored as 0.11 and Excel uses this underlying value in all formulas and calculations.In other words, the formula =A2.11% is equivalent to =A2.0.11. Naturally, you are free to use the decimal number corresponding to the percentage directly in a formula if this works better for your worksheets.

Calculating total by amount and percentageFor example, you friend offered you his old computer for $400, which is 30% off the original price. You want to know what the original price was.Since 30% is the discount, you deduct it from 100% first to know what percentage you actually have to pay (100% - 30% = 70%). Now you need the formula to calculate the original price, i.e.
To find the number whose 70% equals 400.The formula goes as follows. Hello,I greatly appreciate your tips of expertise here, as I use them to teach my students.I wondered whether you have a formula for this example:I have one column on an Excel 2016 sheet of dates, ranging in cells B2:B86. In B89, I'd like to reflect the amount of dates in the range; i.e., if all the cells contained a date, then obviously the percentage in B89 would be 100%. But, it looks like not ALL of the cells will have dates, so I need a formula in B89 that will reflect the percentage of dates that DID reflect in the range. Is that possible?Thank you so very much for your help, and I'll continue to share you site with our students.
