How to Calculate Percentage Change Manually?

The calculation of percentage change can be done manually by following these steps:

  1. Find the difference between the final value and the initial value
  2. Divide the difference by the absolute value of the initial amount
  3. Multiply the result by 100 to get the percentage change

Percentage Change Formula

Percentage Change = (V2 – V1) / |V1| × 100
Where V1 = Initial Value, V2 = Final Value

Examples of Percentage Change Calculations

Stock Price Increase Example

Given:

  • Initial Price: $50 per share
  • Final Price: $65 per share

Calculation:

[(65 - 50) / |50|] × 100
= (15 / 50) × 100
= 30%

Result: 30% increase

Sales Decrease Example

Given:

  • January Sales: $10,000
  • February Sales: $8,500

Calculation:

[(8,500 - 10,000) / |10,000|] × 100
= (-1,500 / 10,000) × 100
= -15%

Result: 15% decrease

Frequently Asked Questions (FAQ)

Percentage change is a way to express the change in a value as a percentage of the original value. It shows how much a value has increased or decreased relative to its starting point.

A positive percentage change indicates an increase (the final value is higher than the initial value), while a negative percentage change indicates a decrease (the final value is lower than the initial value). For example, +25% means a 25% increase, while -15% means a 15% decrease.

Percentage change measures the change from an initial value to a final value, showing increase or decrease. Percentage difference compares two values without considering which came first, typically used when comparing two measurements of the same thing.

Yes, percentage change can exceed 100%. This happens when the final value is more than double the initial value. For example, if a price increases from $50 to $150, that's a 200% increase because the change ($100) is 200% of the original $50.
