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 calculator formula
  • 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%
  • Check your answer using percentage calculator.

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%
  • Check your answer using the Percentage Decrease Calculator.
  • 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 Percentage Difference

  • 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%
  • Check your answer using the Percentage Difference Calculator.
  • 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 Percentage Change

  • 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
  • Check your answer using the Percentage Change Calculator.
  • 50 is a –83.33% change of 300.
