Percentage, which is stated as a fraction of 100, is used to express a portion of a whole or a ratio. It is denoted using the percent sign (%).

Percentages are dimensionless numbers and don’t have a unit of measurement.

How to use the Percentage Calculator?

Using the percentage calculator, you can calculate the percentage of a number by entering the percentage and the quantity required for the calculation.

The variables in the calculator include

Percentage (p)
The percentage you want to calculate

Quantity (q)
The quantity you want to calculate percentage of

Answer (A)
The percentage of the quantity is calculated as follows

A=pq×100A = \dfrac{p}{q} \times 100

How to use the Percentage Increase Calculator?

Using the percentage increase calculator, you can calculate the percentage increase in the quantity by entering the values of the initial and final quantities.

The variables in the calculator include

Initial Quantity (I)
The quantity we started out with

Final Quantity (f)
The quantity we ended up with

Percentage Change (P)
The percentage change as calculated using the formula

P=(Final QuantityInitial Quantity−1)×100P = \bigg( \dfrac{\text{Final Quantity}}{\text{Initial Quantity}} - 1 \bigg) \times 100

How to use the Percentage Decrease Calculator?

Using the percentage decrease calculator, you can calculate the percentage decrease in the quantity by entering the values of the initial and final quantities.

The variables in the calculator include

Initial Quantity (I)
The quantity we started out with

Final Quantity (f)
The quantity we ended up with

Percentage Change (P)
The percentage change as calculated using the formula

P=(Final QuantityInitial Quantity−1)×100P = \bigg( \dfrac{\text{Final Quantity}}{\text{Initial Quantity}} - 1 \bigg) \times 100

How to use the Percentage Change Calculator?

Using the percentage change calculator, you can calculate the percentage change in the quantity by entering the values of the initial and final quantities.

The variables in the calculator include

Initial Quantity (I)
The quantity we started out with

Final Quantity (f)
The quantity we ended up with

Percentage Change (P)
The percentage change as calculated using the formula

P=(Final QuantityInitial Quantity−1)×100P = \bigg( \dfrac{\text{Final Quantity}}{\text{Initial Quantity}} - 1 \bigg) \times 100

How to use the Percentage Difference Calculator?

Using the Percentage difference calculator, you can calculate the percentage difference between the given two numbers.

The variables in the calculator include

Value 1 (v1)
The first quantity

Value 2 (v2)
The second quantity

Percentage Difference (P)
The percentage difference between the two quantities is calculated by the following formula

P=∣v1−v2∣(v1+v2)2P = \dfrac{|v_1 - v_2|}{\dfrac{(v_1 + v_2)}{2}}

How to use the Percentage of Percentage Calculator?

Using the Percentage of Percentage Calculator, you can calculate the percentage of a percentage of quantity, by entering the values required.

The variables in the calculator include

Quantity (Q)
The Total Quantity for the calculation

Percentage 1 (P1)
The percentage of the quantity

Percentage 2 (P2)
The percentage 2 you want to calculate

Answer (A)
The percentage of percentage of the quantity given as

A=P1100×P2100×QA = \dfrac{P_1}{100} \times \dfrac{P_2}{100} \times Q

What is the Percentage?

The percentage is used to represent a portion of the quantity. It is expressed as a fraction of 100. It is primarily used to compare two different quantities using a common scale.

We use percentages everywhere, we use percentages in the finance sector, for expressing interest rates, rates of return, tax rates and so many more.

Percentage helps us set our targets and track our progress and evaluate our performance.

How is Percentage Calculated?

To calculate the percentage we have to divide the portion by the total quantity and multiply by 100. As you can see from the formula below.

Percentage=PortionTotal Quantity×100\text{Percentage} = \dfrac{\text{Portion}}{\text{Total Quantity}} \times 100

Examples

Example 1

What Percentage is 55 out of 1100?

To calculate the percentage, we can use the following formula

P=PortionTotal Quantity×100=551100×100=5% \begin{aligned} \text{P} &= \dfrac{\text{Portion}}{\text{Total Quantity}} \times 100 \\[10pt] &= \dfrac{55}{1100} \times 100 \\[10pt] &= 5\% \end{aligned}

So, after calculating we get 55 out of 100 is 5%.
