Percentage Increase refers to the growth in a quantity or value, expressed as a percentage of the original value. It is calculated by determining the difference between the final and initial values, dividing that difference by the initial value, and multiplying the result by 100 to express it as a percentage.

This measure is commonly used to track changes in values over time or between two different quantities, helping to quantify the extent of change. A negative percentage increase would indicate a decrease, often referred to as a percentage decrease.
Percentage Increase Formula
A percentage Increase is a rise in the value by a certain percentage. That means the value of the item has increased by the initial value estimated in a certain period of time.
The percentage increase is calculated by using the percentage increase formula. And, the final figure or value is obtained in percent.
Percentage Increase = {(Final Value - Initial Value) / Initial Value} ×100
The percentage increase formula is a way of calculating the increase in value of the item by a certain percentage from its previous value. Percentage increase means the increase in the value of a product, item, or any such thing concerning its initial value.
How to Calculate Percentage Increase?
We know that the percentage increase is expressed as the difference between the final value and the initial value, which is divided by the initial value and then multiplied by 100. Let us understand how to calculate percentage increases with the help of a few examples.
The percentage increase formula is derived from these steps:
Step 1: Calculate the difference between the final value and the initial value.
Percentage Increase = Final value - Initial value
Step 2: Dividing the obtained value by the initial value and multiply it by 100 to obtain the number in percent.
Percentage Increase = {(Final Value - Initial Value) / Initial Value} × 100
Percentage increase formula is the method to calculate the increased value in a percent. It is done by dividing the difference between the initial value and the final value of the initial value and multiplying by 100.
Example: In a factory production increases from 600 tons to 900 tons in a year. Calculate the percentage increase in production.
Solution:
Initial value = 600 tons
Final value = 900 tonsBy using Percentage Increase Formula
Percentage Increase = [(Final Value - Initial Value)/Initial Value] × 100
= [(900 - 600)/600] × 100
= 50%
Thus, production increased by 50%.
Percentage Increase Calculator
Percentage Increase Calculator is a tool for figuring out how much something has grown in percentage terms. Percentage increase is the ratio, expressed as a percentage, by which a value has grown compared to its original amount.
Percentage Increase vs Actual Increase
Actual Increase
Actual increase refers to the absolute change in value. It is found by subtracting the initial value from the final value.
Formula:
Actual Increase = Final Value − Initial Value
Example: If a value increases from 40 to 50, Actual Increase = 50 − 40 = 10
Percentage Increase
Percentage increase expresses the change relative to the initial value, in percentage form.
Formula:
Percentage Increase = {(Final Value - Initial Value) / Initial Value} × 100
Example: If a value increases from 40 to 50, Percentage Increase = (10/40) × 100 = 25%
Percentage Increase vs Percentage Decrease
Some of the common differences between percentage increase and decrease are:
| Aspect | Percentage Increase | Percentage Decrease |
|---|---|---|
| Definition | An increase in value by a certain percentage | A decrease in value by a certain percentage |
| Representation | Positive change | Negative change |
| Impact on Value | Value rises | Value declines |
| Direction on a Graph | Upward trend | Downward trend |
| Interpretation | Indicates growth or improvement | Indicates decline or deterioration |
| Context | Generally viewed positively | Generally viewed negatively |
| Example | If a product's price increases by 20%, the its new price will be (100+20)% of its original price | If a product's price decreases by 15%, the its new price will be (100-15)% of its original price |
| Calculation Formula | Percentage Increase =(New Value − Original Value)/Original Value × 100 | Percentage Decrease = (Original Value − New Value)/Original Value × 100 |

Solved Examples Percentage Increase
Example 1: Calculate the percentage increase in the rent of a house if in the month of August rent is 3000 rupees and in the month of May rent was 2000?
Solution:
Initial rent = 2000; Increased rent = 3000
Percentage Increase Formula
Percentage Increase = [(Final Value - Initial Value)/Initial Value] × 100.
= [(3000 - 2000)/2000] × 100 = [1000/2000] × 100
= [1/2] × 100
= 50%
Thus, Percentage increase in rent is 50%
Example 2: Calculate the percentage increase from 120 to 200?
Solution:
Given:
Initial value is 120.
Final value is 200.
Percentage Increase Formula
Percentage Increase = {(Final Value - Initial Value) / Initial Value} × 100
= ( (200 - 120) / 120) × 100
= ( 80 / 120 ) x 100
= 66.67%
Example 3: Calculate the percentage increase in the fees of a student from class 9 to class 10 if the fees of class 9 are 1000 and of the class are 1200?
Solution:
Increase in fees = fees of class 10 - fees of class 9
= 1200 – 1000
= 200Fees of class 9 = 1000
Percentage Increase Formula
Percentage Increase = (Increase in fees ⁄ fees of class 9) × 100
= (200 ⁄ 1000) × 100
= 20%Thus, there is a 20% increase in the fees of student.
Example 4: Calculate the percent increase from 5 to 6?
Solution:
Percentage change is percentage increase as the number rises from 5 to 6.
Increase in value = 6-5 = 1
Percentage Increase Formula
Percentage Increase = 1/5 = 0.2 × 100
= 20%Thus, from 5 to 6, percentage increase is 20%.
