How to Calculate Percent Change

Percent change is a measure of how much a value has increased or decreased from an initial amount to a final amount, expressed as a percentage. It's a crucial concept in various fields, including finance, statistics, and science.

Percent Change Formula

The formula to calculate percent change is:

\[ Percent Change = \frac{Final Value - Initial Value}{Initial Value} \times 100\% \]

Where:

  • Initial Value is the starting amount
  • Final Value is the ending amount

Calculation Steps

  1. Identify the initial value and final value.
  2. Subtract the initial value from the final value to find the change.
  3. Divide the change by the initial value.
  4. Multiply the result by 100 to convert to a percentage.

Example Calculation

Let's calculate the percent change from 50 to 75.

Step 1: Identify the values

Initial Value = 50
Final Value = 75

Step 2: Calculate the change

Change = Final Value - Initial Value
Change = 75 - 50 = 25

Step 3: Apply the formula

\[ Percent Change = \frac{25}{50} \times 100\% = 0.5 \times 100\% = 50\% \]

Step 4: Interpret the result

The percent change from 50 to 75 is a 50% increase.
