Understanding Budget Increase Percentage

Budget increase percentage represents the extent of the rise in the budget from one period to another, shown as a percentage of the original budget. It is a useful metric for understanding growth, planning future expenses, and making informed financial decisions.

Calculating this percentage allows you to easily compare budget changes across different departments, projects, or time periods. It offers a standardized way to assess whether your budget is growing, shrinking, or remaining stable.

The Formula for Calculating Budget Increase Percentage

The formula to calculate budget increase percentage is straightforward:

Budget Increase Percentage = [(New Budget - Original Budget) / Original Budget] x 100

Where:

  • New Budget is the budget amount in the current period.
  • Original Budget is the budget amount in the previous period.

Steps to Calculate Budget Increase Percentage

  1. Determine the Original Budget: Identify the budget amount from the previous period. This is your starting point.
  2. Determine the New Budget: Identify the budget amount for the current period. This is the value you're comparing against the original.
  3. Calculate the Difference: Subtract the Original Budget from the New Budget. This gives you the amount of the increase.
  4. Divide by the Original Budget: Divide the difference you calculated in step 3 by the Original Budget.
  5. Multiply by 100: Multiply the result from step 4 by 100 to express the increase as a percentage.

Examples of Calculating Budget Increase Percentage

Let's look at a couple of examples to illustrate how to use the formula:

Example 1: Departmental Budget Increase

A marketing department had an original budget of $50,000. In the next fiscal year, their budget increased to $60,000. Let's calculate the budget increase percentage.

  1. Original Budget = $50,000
  2. New Budget = $60,000
  3. Difference = $60,000 - $50,000 = $10,000
  4. Divide by Original Budget: $10,000 / $50,000 = 0.2
  5. Multiply by 100: 0.2 x 100 = 20%

Therefore, the marketing department's budget increased by 20%.

Example 2: Project Budget Increase

A project had an initial budget of $20,000. Due to unforeseen circumstances, the budget was increased to $22,000. Calculate the budget increase percentage.

  1. Original Budget = $20,000
  2. New Budget = $22,000
  3. Difference = $22,000 - $20,000 = $2,000
  4. Divide by Original Budget: $2,000 / $20,000 = 0.1
  5. Multiply by 100: 0.1 x 100 = 10%

Therefore, the project budget increased by 10%.
