**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 Percentage** **Difference**

- 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 Percentage** **Change**

**Change**

- 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.
