We'll explore the concept of percentage calculation and how a percentage calculator can simplify this process for you.

How to Calculate Percentage

Basic Percentage Calculation

Calculating a percentage is essentially finding a portion of a whole. The formula for calculating percentage is:

Percentage = (Part/Whole) × 100

For example, if you scored 35 out of 50 on a test, the percentage would be:

(35/50) × 100 = 70%

Percentage Increase Calculation

To calculate the percentage increase, you can use the following formula:

Percentage Increase = (New Value - Old Value / Old Value) × 100

For instance, if the price of a product increased from $50 to $60, the percentage increase would be:

(60-50 / 50)  × 100 = 20%

Percentage Decrease Calculation

Similarly, to calculate percentage decrease, you can use this formula:

Percentage Decrease = (Olv Value - New Value / Old Value) × 100

For example, if the temperature decreased from 20°C to 15°C, the percentage decrease would be:

(20-15 / 20)  × 100 = 25%
