Calculating the percentage of a score is a fundamental skill, whether you're a student trying to understand your grades, a teacher assessing performance, or anyone needing to quantify results. It’s all about understanding the relationship between the points earned and the total possible points. Fortunately, with PercentageFinder.org's easy-to-use calculator, figuring out percentages is quick and straightforward. Let's dive in!

Calculate Your Score Percentage Now! →The Basic Formula
The core formula for calculating the percentage of a score is simple:
Percentage = (Scored Points / Total Possible Points) x 100
This formula applies to any scoring scenario, from tests and quizzes to assignments and projects.
Step-by-Step Calculation
- Identify Scored Points: Determine the number of points you (or the student) achieved.
- Determine Total Possible Points: Find out the maximum possible score.
- Apply the Formula: Divide the scored points by the total points, then multiply by 100.
Example: If you scored 75 points on a test with 90 possible points, the calculation would be (75 / 90) * 100 = 83.33%.
Dealing with Multiple Scores
Sometimes, you might need to calculate the percentage of a combined score from multiple assignments or tests. In this case, you'll need to adapt the basic formula slightly:
- Sum all the Scored Points: Add up the points earned on each individual assessment.
- Sum all the Total Possible Points: Add up the maximum possible scores for each assessment.
- Apply the Modified Formula: Divide the total scored points by the total possible points, then multiply by 100.
Example: Suppose you received the following scores. Test 1: 90/100, Test 2: 45/50, Test 3: 22/25. The calculation would be ((90 + 45 + 22) / (100 + 50 + 25)) * 100 = (157 / 175) * 100 = 89.71%
Percentage Increase or Decrease
Calculating the percentage change, whether an increase or decrease, can be useful for tracking progress or analyzing score trends.
The formula to calculate the change is:
Percentage Change = ((New Value - Old Value) / Old Value) * 100
A positive result indicates an increase, while a negative result indicates a decrease.
Example: If a student's score improved from 70 to 85, the percentage increase would be ((85 - 70) / 70) * 100 = 21.43%

Understanding Different Grading Systems (Crosslinking)
While percentage scores are universal, the way they translate into grades can vary. Different schools, institutions, and even individual teachers may use different grading scales. For related information, see https://percentagefinder.org/blog/grade-calculator and similar calculators.
