What Is Percentage Distribution?

Percentage distribution shows what share each component contributes to a whole. It is used in budgeting, data analysis, business reporting, and everyday splitting of costs.

Two Modes

Mode 1: Find Percentage of Each Item

Enter a list of values. The calculator shows what percentage each one is of the total.

Example: Sales by region: North $45,000, South $30,000, East $25,000
Total: $100,000 | North: 45%, South: 30%, East: 25%

Mode 2: Distribute a Total Proportionally

Enter a total amount and percentage splits. The calculator shows the actual amounts.

Example: $1,200 rent, split 40/35/25: $480 / $420 / $300

Common Applications

  • Budgeting: Allocate income across expense categories
  • Business: Revenue share between departments or products
  • Investing: Portfolio allocation percentages
  • Splitting bills: Fair split based on usage or income
  • Data analysis: Breakdown of survey responses

Weighted Distribution

For unequal splits, enter custom percentages that sum to 100%. For equal distribution among N items, each receives 100/N percent. This calculator handles both cases.
