What is the percentage formula?

What is percent of 20

In this guide, we’re going to explore some techniques that will help you efficiently calculate percent in Excel and learn basic percent formulas that take the guesswork out of your calculations.

By mistake, there is no universal Excel formula for percent that covers all possible scenarios. If you ask someone for the percentage formula they use to get the result they were looking for, they will most likely answer that it depends on exactly what result you want to achieve.

If you compare it to the basic mathematical percentage formula, you will notice that Excel’s percentage formula lacks the * 100 part. When calculating in Excel, you do not have to multiply the resulting fraction by 100, as Excel does it automatically when the percentage format is applied to an Excel cell.

The same sequence of steps must be performed when using any other percentage formula in Excel. In the following example, column D shows a rounded percentage of delivered items, without showing decimals.

Percent mass concentration, also called percent mass/mass or %m/m, is a physical unit of concentration that indicates how many parts by mass of solute are present per 100 parts or mass units of solution or mixture. Depending on the units, this can be interpreted in different ways. For example:

In fact, anyone who looks at the purity or concentration data for any commercial chemical reagent will find that these values are invariably stated on the label as a mass percent. Data such as density, which can be used to determine concentration in other units, are also reported, but these values are reported at specific conditions of temperature and pressure.

If the conditions at the time of using the reagent to prepare another solution or for use in any other application are not the same as those reported, then any volume or volume-dependent unit of concentration calculated from these data will inevitably have some degree of error.

In demography, as in many other statistical and social disciplines, it is very common to express relationships between two magnitudes in the form of percentages or “percents” (also in “per thousand”, “per hundred thousand”, etc.). The calculation of the percentage is very elementary, but this web is for very different people, many of you are students of first cycles, and I have already received several comments with questions about how to do this calculation. One example is Jesi’s question:

I thought that the answer can be useful to many others of you who use ApdD, students or teachers, so this entry is to explain 1) the procedure to do the calculation, but also, 2) some ideas that allow to understand the procedure.

The sign * replaces here the usual “x” of arithmetic multiplication, because when using expressions with “unknowns”, as in equations, the letters are reserved for naming them, as in y=2x.

a) All the offices of a company have a ratio of 4 to 1 between administrative and analysts. How many analysts does the Lima office, which has 40 administrative staff, have so that the ratio remains constant at 4 to 1?

REMARK If you use rules of three to solve percentage problems, you will not have much trouble to clear the unknown, whether it is the part, the total or the percent. If you interpret percents as fractions, you should have no difficulty clearing either, but you will not be dealing with a process as mechanized as a rule of three, so you should pay special attention.

When solving problems with percentages, the statement will give us two of the three elements involved and we will have to calculate the missing one. Below you will find three examples solved using rules of three, one for each of the possible situations. You can try to solve them using the other interpretations of the percentages.

If you have read the reflection on the previous page, you will know that if we want to calculate, for example, 21% of any amount, we can calculate separately 20% and 1% and then add them together. Can we always add percentages calculated separately? It depends. If the percentages are calculated on the same total, we can add and subtract them freely. We would be applying the distributive property in that case. However, when the percentages are applied to different totals we cannot add or subtract them.
