If your company only generates 25% of its total revenue each month, you might have trouble with this calculator. Start with 12 months of data or go back in time, to date methods and spreadsheets.

Percent

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.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.This is all nice, but we usually do not use percents just by themselves. Mostly, we want to answer how big is one number in relation to another number?. To try to visualize it, imagine that we have something everyone likes, for example, a large packet of cookies (or donuts or chocolates, whatever you prefer 😉 - we will stick to cookies). Let's try to find an answer to the question of what is 40% of 20? It is 40 hundredths of 20, so if we divided 20 cookies into 100 even parts (good luck with that!), 40 of those parts would be 40% of 20 cookies. Let's do the math:So what is percentage good for? As we wrote earlier, a percentage is a way to express a ratio. Say you are taking a graded exam. If we told you that you got 123 points, it really would not tell you anything. 123 out of what? Now, if we told you that you got 82%, this figure is more understandable information. Even if we told you, you got 123 out of 150; it's harder to feel how well you did. A week earlier, there was another exam, and you scored 195 of 250, or 78%. While it's hard to compare 128 of 150 to 195 of 250, it's easy to tell that 82% score is better than 78%. Isn't the percent sign helpful? After all, it's the percentage that counts!

Although Ancient Romans used Roman numerals I, V, X, L, and so on, calculations were often performed in fractions that were divided by 100. It was equivalent to the computing of percentages that we know today. Computations with a denominator of 100 became more standard after the introduction of the decimal system. Many medieval arithmetic texts applied this method to describe finances, e.g., interest rates. However, the percent sign % we know today only became popular a little while ago, in the 20th century, after years of constant evolution.The term percent is often attributed to Latin per centum, which means by a hundred. Actually, it is wrong. We got the term from Italian per cento - for a hundred. The percent sign % evolved by the gradual contraction of those words over centuries. Eventually, cento has taken the shape of two circles separated by a horizontal line, from which the modern % symbol is derived. The history of mathematical symbols is sometimes astonishing. We encourage you to take a look at the origin of the square root symbol!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). Whether you want to work out an appropriate tip at a restaurant, find out what percentage discount you’re receiving on a product or determine what a specific percentage of a number is, the need to know how to find the percent of something comes up regularly. To calculate percent values, you need to understand what percentage really means. Converting between decimal proportions and percentages is simple, but it also makes it really easy to estimate simple percentages and perform more complicated calculations. (Source: sciencing.com)

As the numerous examples above demonstrate, a percentage calculator can be useful in so many practical scenarios. Changes in electoral sentiment in democratic processes, industrial production, stocks of material goods in warehouses, albums sold by an artist / musician, publications in a scientific journal, personnel changes in an organization, as well as natural things such as the amount of flora or fauna in given island, etc. can be computed using such a tool. Another application of percentage calculations is for differences in achievements such as records at Olympic games and other tournaments and championships. To average percentage growth a year, it would be incorrect to just sum up the growth % in each year and then divide by the number years. Let us say you are the founder of an organization which has an asset that grew 5% the first year, 6% the second year, 10% the third year, and then lost 10% the fourth year. The growth of the principal value is not 5% + 6% + 10% - 10% = 11%, but it is instead the geometric mean: 2.4549% times the number of years = 2.4549 x 4 = 9.82%. Again, this is not something you can solve for using the above calculator.

Here is an example of adding percentages: say you have a $100,000 bank deposit at a 2% interest rate, applied yearly at the end of the year. If you keep it for 5 years, you might think that the way to calculate your deposit's value at the end of the 5-year period is to simply multiply 2% x 5 = 10% (or, equivalently, 2% + 2% + 2% + 2% + 2% = 10%), add 100% and then use our percentage calculator to calculate 110% of $100,000. By this calculation you would expect to have $110,000 at the end of the period (10% of 100,000 is $10,000). However, you will have $110,408, since at the end of each year you will get your interest but then in each of the following years you will accrue interest over the interest from the first year. And so on for the second, third... This is what most people mean when they want to know "how to calculate percentage", but for other possible percentage calculations see below. Percent change calculators are commonly employed when comparing quantities, business metrics, or other measurements from two time periods. A percentage change calculation is also useful when comparing a new state of things to an old state of things, e.g. using the census to compare the number of people living in villages in a given municipality before versus after industrialization. Our calculator is of great assistance for calculating percent increase / decrease, but you can also find the percentage change on your own. (Source: www.gigacalculator.com)

In another situation, you might be examining a proposition to increase your salary from $100,000 a year to $120,000 a year to keep you on the payroll and want to find what percent is the new salary versus your old one. If you do the math manually, start by dividing 120,000 by 100,000 to get 1.2. Then multiply by 100 to get 120. Finally subtract 100 which leaves 20%. Therefore, you were offered a 20% increase of your salary and as the new salary is 120% of your current salary.

This is all nice, but we usually do not use percents just by themselves. Mostly, we want to answer how big is one number in relation to another number?.
