Just make your calculations easy and simple with the help of Percentage Calculator. It is a calculator which is used to calculate the percentage of all levels. It can be freely or easily accessible on the web. This instant calculator helps in taking out the percentage or proportion of a number as well as reverse percentage calculations. But before that you must know thoroughly about the definition, facts, formulas to use this calculator more accurately!


Percentage implies every 100 or parts per 100. The Percentage can be utilized to depict a bit of an entire or peice of an entirety. It originates from every penny which is short for every ‘centum’ which implies every hundred.

The percent sign is: %

1 percent (1%) = 1 section every 100 = 1/100 = 0.01  (a partition not as much in general)

100 percent (100%) = 100 sections every 100 = 100/100 = 1  (a segment equivalent to an entirety)

110 percent (110%) = 110 sections every 100 = 110/100 = 1.1  (a segment more prominent than an entirety)


A sum total of per 100 that refers to a section of a whole, in a general way, typically without using a specific number, is known as percentage.

Percentage History Facts

Getting more into the percentage world, The term "per cent" came from the Latin per centum, signifying "by the hundred". The sign for "per cent" developed by steady limitation of the Italian term every cento, signifying "for a hundred". The “per” was regularly curtailed as "p." and inevitably vanished completely. The "cento" was contracted to two circles differentiated by an even line, from which the advanced "%" image is determined.

Percentage Formula:

This Formula is utilized to solve the percentage queries that speaks about two ratios, where one of the ratios is a part or portion per 100 and the other ratio is a part or portion per a whole.


A% of B is C                                     as in:  10% of 50 is 5      where A=10, B=50, C=5

The percentage formula is:

A/100 x B = C                                   as in:  10/100 x 50 = 5


A100 = CB                                               as in:  10100 = 550

The percentage formula is sometimes expressed as:

percent100 = is (part) of (whole)                           as in:  10100 = 550

Solving for each of the variables yields:

A = (C / B) x 100                              as in:  A = (5 / 50) x 100 = 10

B = C / (A / 100)                               as in:  B = 5 / (10 / 100) = 50

C = (A / 100) x B                              as in:  C = (10 / 100) x 50 = 5

Note: A% = A/100 because % means per 100

Document Details:

In mathematics, we denote percentage as a number or ratio uttered as a fraction of 100. We express percentage with a sign of “%", or with the abbreviation of "pct."

It comes from two words: per and cent, which is short for per centum which means per hundred. Also, it is written in two forms, percentage and percentile.

The value of percent is calculated by multiplying the numeric value of the ratio by 100. For example, to hit upon 50 pens as a percentage of 1250 pens, first calculate the ratio 50/1250 = 0.04, and then multiply by 100 to get hold of 4%. The percent value can also be found by multiplying first, so in this example the 50 would be multiplied by 100 to provide 5,000, and this result would be divided by 1250 to give 4%.

To calculate a percentage of a percentage, convert both percentages to fractions of 100, or to decimals, and multiply them. For example, 50% of 40% is:

(50/100) × (40/100) = 0.50 × 0.40 = 0.20 = 20/100 = 20%.

NOTE: It is not correct to divide by 100 and use the percent signal at the same time. (E.g. 25% = 25/100 = 0.25, not 25% / 100, which actually is (25/100) / 100 = 0.0025. A term such as (100/100) %

would also be incorrect, this would be read as (1) percent, even if the intent was to say 100%.)

How to use the Calculator?

Figure out the percentage of a number comprehending the comparison P% * X = Y for Y or discover the rate of one number to another understanding the mathematical statement Y/X = P% for P or locate an entire number from a rate part unraveling Y/P% = X for X.

Alteration in rate as an expand (+) or decline (-) can be figured utilizing Percentage Change Calculator while percentage changes, can be comprehended with Decimal to Percent, Percent to Decimal, Fraction to Percent, or Percent to Fraction.

How are Percentages used?

 AT Store discounts, you may find percentage visible like 40% percent off sale

    Sales tax is normally a percentage of Purchase Price like, 10% sales tax on any item you buy

    Interest rates for savings accounts are typically shown as an annual percentage rate (apr): 1.5% apr

    How online calculation takes place?

To use Percent Calculator, one needs to fill the two given fields. After filling the two fields, click the "Calculate" button to get the third value which is the result.

For example, 45% is equivalent to 0.45 or 45/100. The calculator above can take any two values and calculate the third value. Examples:

    5 percent of 100 = ?

    ? percent of 30 = 1.5

    5 percent of ? = 1.5

Thus, Percentages are very helpful in finding the relationship between a portion and a whole, which is quite easier to understand. But, sometimes calculations become tough that we manually can’t able to do that. Well, in that case, nothing better than the percentage calculator
