Percentage Calculator helps you to calculate percentage using percentage formula. Different types of Percentage Calculators are displayed below. These are multiple online percentage calculators.

## Percentage Formula

The Percentage Calculation Formula can be written in different forms, it is essentially an algebraic equation involving three values. The basic form of Percentage formula

is Percentage Formula(P)% =(Value(x)/Total Value(y)) * 100

• Percentage Formula will be simply written as P=(x/y) *100
• “P” is the percentage.
• “x” is the value for which percentage can be calculated.
• “y” is the total value from which percentage is calculated.
• To calculate percentage of a number we require two numbers i.e., value(x) and total value(y).

## Find Percentage Of a Number

• Let us find Percentage Of a Number 20 from 600
• From the above example it is said that–>What percent of 600 is 20?
• From this example, it is given that Value(x)=20, Total Value(y)=600.
• Then Percentage(P)=(x/y) *100=(20/600)*100=(0.333)*100=3.33%

## How To Calculate Percentage Of A Number

• Calculating Percentage Of A Number 50 from 300
• Here Value(x)=50 and Total Value(y)=300
• Enter these values in the formula above.
• Perform the operation x/y=50/300=0.1666
• multiply 0.1666 by 100 to get 16.66%
• Check your answer using percentage calculator.

## How To Calculate Percentage Of Marks?

Example: What percent of 600 is 550?

• Let us calculate percentage of a number “550” from total number “600”.
• In this we got value(x)=550 and total value(y)=600.
• Then Percentage(P)=?
• then percentage of a number (P)=(550/600) *100 =(0.916) *100 =91.6%
• In this way you can find percentage of a number.

## Percentage Calculation Formula

From the percentage formula, we can get two other cases such as,

### Finding “x” Value if Percentage(P) and Total Value(y) is present:

From the Percentage formula we can derive other formula to calculate the value(x).

i.e., Value(x)=(Percentage(P)*Total Value(y))/100

It will be simply written as: x=Py/100

Example: What is 35% of 600?

• From this example percentage(P)=35%
• Total Value(y)=600
• Then Value(x)=?
• Then x=Py/100=(35*600)/100=21000/100=210
• Therfore Value(x)=210.

### Finding “y” Total Value if Percentage(P) and value(x) is present:

From the Percentage formula we can derive other formula to calculate the Total Value(y) if Percentage(P) and value(x) is present.

i.e., Total Value(y)=(Value*100)/Percentage(P)

It will be simply written as: y=(x*100)/P

Example: 60 is 30% of what number?

• From this example Percentage(P)=30%
• Value(x)=60
• Then Total Value(y)=?
• Then y=(x*100)/P=(60*100)/30=600/30=200
• Therefore Total Value(y)=200.

## Percentage Increase/Decrease Calculator

Percentage Decrease Calculator Formula

Percentage decrease % = ((final value- initial value)/initial value) * 100

### How To Calculate Percentage Decrease

• Take initial value as 100 and final value as 10
• Enter these values in above Percentage Decrease Formula
• Perform the operation 10-100=-90
• Divide -90 by 100 to get -0.9
• multiply -0.9 by 100 to get -90%
• Check your answer using the Percentage Decrease Calculator.
• 10 is a 90% decrease of 100.

## Percentage Difference Calculator

Percentage Difference Calculator formula

Percentage Difference Formula=((v1-v2)/(v1+v2)/2) *100

### How To Calculate PercentageDifference

• Let suppose take value(v1) as 100 and value(v2) as 10
• Enter these values in above Percentage Difference Formula
• Perform the operation v1-v2=100-10=90
• Perform the operation (v1+v2)/2=(100+10)/2=110/2=55
• Divide 90 by 55 to get 1.6363
• multiply 1.636363 by 100 to get 163.63%
• Check your answer using the Percentage Difference Calculator.
• The percentage difference between 100 and 10 is 163.6%.

## Percentage Change Calculator

Percentage Change Calculator formula

Percentage Change formula=((v2-v1)/v1) *100

### How To Calculate PercentageChange

• Take initial value(v1) as 100 and final value(v2) as 10
• Enter these values in above Percentage Change Formula
• Perform the operation 10-100=-90
• Divide -90 by 100 to get -0.9
• multiply 0.9 by 100 to get -90% change
• Check your answer using the Percentage Change Calculator.
• 10 is a –90% change of 100.
