**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%
- 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**

**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.
