The Formula for Percentage Growth

The percentage growth formula is used to determine the percentage change in value over a period of time. It's calculated as follows:

Percentage Growth = [(New Value - Original Value) / Original Value] * 100

Where:

  • New Value is the value at the end of the period.
  • Original Value is the value at the beginning of the period.

Steps to Calculate Percentage Growth

  1. Identify the Original Value: Determine the starting value you are comparing against.
  2. Identify the New Value: Determine the ending value you are comparing to the original.
  3. Calculate the Difference: Subtract the original value from the new value (New Value - Original Value).
  4. Divide by the Original Value: Divide the result from Step 3 by the original value.
  5. Multiply by 100: Multiply the result from Step 4 by 100 to express the growth as a percentage.

Examples of Calculating Percentage Growth

Example 1: Sales Growth

A company's sales increased from $100,000 in 2022 to $120,000 in 2023. Let's calculate the percentage growth:

  1. Original Value: $100,000
  2. New Value: $120,000
  3. Difference: $120,000 - $100,000 = $20,000
  4. Divide: $20,000 / $100,000 = 0.2
  5. Multiply: 0.2 * 100 = 20%

Therefore, the sales growth is 20%.

Example 2: Investment Growth

An investment increased from $5,000 to $5,750. What is the percentage growth?

  1. Original Value: $5,000
  2. New Value: $5,750
  3. Difference: $5,750 - $5,000 = $750
  4. Divide: $750 / $5,000 = 0.15
  5. Multiply: 0.15 * 100 = 15%

Therefore, the investment growth is 15%.

  • Personal Finance: Monitor the increase in savings or the decrease in debt.
  • Academic Performance: Evaluate improvements in test scores or grades.

Percentage Growth vs. Absolute Growth

It's important to distinguish between percentage growth and absolute growth. Absolute growth refers to the actual increase in quantity, while percentage growth expresses this increase relative to the original amount. Percentage growth provides a more meaningful comparison when dealing with different scales. For example, an increase of 10 units is significant if the original value is 100, but less so if the original value is 1,000.
