How to Calculate Percentage of Total

Calculating a percentage of a total helps determine how much one category contributes to an overall amount.

This calculation appears frequently in budgets, business reports, surveys, analytics, school results, and financial statements.

Formula

Use:

Percentage of Total = (Part ÷ Total) × 100

For example, imagine a company’s total monthly expenses are $20,000 and advertising costs $4,000.

Calculate:

(4,000 ÷ 20,000) × 100 = 20%

Advertising represents 20% of the total monthly expenses.

Another Example

Suppose a website receives 100,000 visits:

Organic Search: 50,000
Paid Search: 25,000
Social: 15,000
Other sources: 10,000

Organic Search represents:

(50,000 ÷ 100,000) × 100 = 50%

Therefore, half of the website’s traffic comes from organic search.
