# Different types of Percentage Calculators

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 can 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 30 from 500
• From the above example it is said that–>What percent of 500 is 30?
• From this example, it is given that Value(x)=30, Total Value(y)=500.
• Then Percentage(P)=(x/y) *100=(30/500)*100=(0.06)*100=6%

## How To Calculate Percentage Of A Number

• Calculating Percentage Of A Number 40 from 500
• Here Value(x)=40 and Total Value(y)=500
• Enter these values in the formula above.
• Perform the operation x/y=40/500=0.08
• multiply 0.08 by 100 to get 8%

## How To Calculate Percentage Of Marks?

Example: What percent of 500 is 470?

• Let us calculate percentage of a number “470” from total number “500”.
• In this we got value(x)=470 and total value(y)=500.
• Then Percentage(P)=?
• then percentage of a number (P)=(470/500) *100 =(0.94) *100 =94%
• 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 60% of 500?

• From this example percentage(P)=60%
• Total Value(y)=500
• Then Value(x)=?
• Then x=Py/100=(60*500)/100=30000/100=300
• Therfore Value(x)=300.

### 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: 50 is 40% of what number?

• From this example Percentage(P)=40%
• Value(x)=0
• Then Total Value(y)=?
• Then y=(x*100)/P=(50*100)/40=5000/40=125
• Therefore Total Value(y)=125.

## 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 60 and final value as 40
• Enter these values in above Percentage Decrease Formula
• Perform the operation 40-60=-20
• Divide -20 by 60 to get -0.3333
• multiply -0.3333 by 100 to get -33.33%
• 40 is a 33.33% decrease of 60.

## 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 500 and value(v2) as 100
• Enter these values in above Percentage Difference Formula
• Perform the operation v1-v2=500-100=400
• Perform the operation (v1+v2)/2=(500+100)/2=600/2=300
• Divide 400 by 300 to get 1.3333
• multiply 1.3333 by 100 to get 133.33%
• The percentage difference between 500 and 100 is 133.33%.

## Percentage Change Calculator

Percentage Change Calculator formula

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

### How To Calculate PercentageChange

• Take initial value(v1) as 300 and final value(v2) as 50
• Enter these values in above Percentage Change Formula
• Perform the operation 50-300=-250
• Divide -250 by 300 to get -0.83333
• multiply -0.83333 by 100 to get -83.33% change
