Percentages play an integral part of everyday life. From shopping to calculating tips at restaurants, understanding percentage calculations can prove useful in various situations.

Calculating a percentage requires knowing the ratio between two values, then multiplying this figure by 100 to get its percentage value.


Total Percentages are numbers used to express a portion of something relative to 100, calculated by dividing one part (the numerator) by another whole (the denominator), then multiplying that result by 100. They can also be expressed in decimals – written as fractions with decimal points such as 0.41 for instance). Our calculator makes this task simple by quickly and accurately calculating total percentages as well as multiplying out their answer into scientific notation, thus decreasing its number of digits required by multiplying it by 10. This calculator offers several features, such as easily calculating total percentages while also multiplying answers with scientific notation to reduce number of digits required, further decreasing number digits required in calculations by multiplying by 10.

When dealing with percentages, it’s essential to remember they are calculated using ratios – meaning the relative frequency of subgroups within an overall group can be found by dividing their number by 100 and multiplying. As an example, five red balloons could be counted in 50-balloon bag and finding their proportion can be done similarly.

Another popular application of the percentage formula is to calculate differences between two values, often by dividing one value by another and multiplying by 100%. A positive answer indicates an increase in that particular variable; an answer of negative percentage indicates a decrease.

Utilizing a percentage calculator can be invaluable in solving many types of percentage-related issues in everyday life. From discount calculations, tax rates and sales taxes, to saving money through investment accounts or increasing car insurance coverage; percentage calculators are an essential resource.

Though some calculations can be performed mentally, an online percentage calculator can make more complicated calculations easier and can even convert decimals to percentages and vice versa, which is particularly helpful when working with numbers containing multiple decimal points.

Use our online percentage calculator to gain more advanced skills with percentage calculations, such as finding the definite integral of a function and solving for specific variables in equations. The online calculator is simple to use, with instant answers displayed instantly on-screen – an ideal resource for students, business professionals, and others who frequently require performing complex percentage calculations. Additionally, this calculator is free and available all of the time; all it requires is internet connectivity – unlike some other calculators that may work on mobile devices. As always when answering online calculators it’s wise to double check answers are accurate; also be mindful that results may differ depending on accuracy of input data.


A percentage is a fraction with 100 as its numerator that represents the proportion between something and everything else. Working with percentages can make things simpler as one/100 = 0.10 (or 1/100).

One of the most frequently asked questions is “how much greater is one value compared to another” or “what is the percentage increase or decrease of this number compared to its previous value?” Our percentage calculator makes this calculation easy by offering you a formula to calculate the percent difference between two values, as well as another calculator which solves for percentage increase or decrease of specific numbers.

Percentages are an invaluable and incredibly versatile mathematical tool, and can be found everywhere from business to health applications. Credit card and mortgage interest rates, for example, often use percentages when charging interest; similarly, when shopping in malls you might notice signs advertising the percentage off items being offered by various stores.

There are four main categories of percentage problems you will likely face throughout your life, and our calculators can assist with all four. One such example is “What percentage is this number a part of?,” which our calculator can assist with by entering in both initial value and desired percentage.

For instance, to calculate a percentage, divide an original number by its total count and multiply by 100%. If there are 8 red beads and 12 blue beads totalling 20 in all, their combined percentage would be 20 / 100 * 100 = 20%.

Calculating a percentage is sometimes necessary, so when adding decimals it is often beneficial to convert into decimals as this makes your calculations simpler and clearer. For instance, the percentage of 25 is 25%.

Convert a decimal to a percentage by dividing by 100; for instance, 0.4 is equal to 1/100 of 100, or 40%. Conversely, convert percentages back into decimals by multiplying them by 100.

Scientific notation is used throughout science, technology and medicine as an efficient method to display small or large numbers. This notation method simplifies their expression using powers of 10, as well as decreasing errors when working with very large or very small numbers. Mathematicians also utilize it frequently when computing large or small numbers by decreasing zeroes and digits that must be written – also helping reduce errors when working with very large or very small numbers. You can convert any percentage to scientific notation simply by multiplying by 10, making this tool incredibly helpful when learning or teaching percentages!
