Percentage Of Total Calculator
🔢 What Is a Percentage of Total?
A percentage of total tells you how much one value represents as a portion of another value (the total), expressed as a percent. The formula is:
Percentage = (Part / Total) × 100
For example, if you scored 45 out of 50 on a test, your score percentage would be:
(45 / 50) × 100 = 90%
This kind of calculation is extremely common in academic grading, sales analysis, budgeting, fitness progress tracking, and more.

Our calculator automates this formula. You just need to enter two values:

Once you click Calculate, the tool immediately displays what percentage the part is of the total.
