How to Calculate Your Average Grade (Weighted & Unweighted Methods)

Every student wants to know where they stand — and the average grade is the clearest indicator of your academic performance. Whether you’re calculating grades for high school, college, or an online course, understanding weighted vs. unweighted averages helps you get accurate results.

In this guide, we’ll walk through:

• How to calculate your unweighted average
• How to calculate your weighted average
• Common grading systems and examples
• How to use the Average Grade Calculator to make it all automatic

What Is an Average Grade?

An average grade represents your overall performance across multiple assignments, exams, or courses. It’s typically expressed as a percentage (%), letter grade (A, B, C...), or GPA scale (0–4.0).

You can calculate your average grade in two main ways:

• Unweighted average: All grades are treated equally
• Weighted average: Each grade has different importance or “weight”

How to Calculate an Unweighted Average Grade

An unweighted average is the simplest form — it treats all grades equally.

Formula:

Average Grade=Sum of All GradesTotal Number of Grades\text{Average Grade} = \frac{\text{Sum of All Grades}}{\text{Total Number of Grades}}Average Grade=Total Number of GradesSum of All Grades​

Example:

You received these grades:

• Math: 85%
• Science: 90%
• English: 80%

Step 1: Add them all up → 85 + 90 + 80 = 255
Step 2: Divide by 3 subjects → 255 ÷ 3 = 85% average grade

So, your unweighted average is 85% (B grade).

How to Calculate a Weighted Average Grade

Weighted grades are more accurate when different categories (like exams, quizzes, or homework) carry different importance.

Formula:

Weighted Average=∑(Grade×Weight)∑(Weights)\text{Weighted Average} = \frac{\sum(\text{Grade} \times \text{Weight})}{\sum(\text{Weights})}Weighted Average=∑(Weights)∑(Grade×Weight)​

Here’s a simple example:

So, the weighted average = 77%.

In this case, exams had more impact since they carried 50% of the total grade weight.

It’s the fastest, most accurate way to track your academic performance in real time.

How to Improve Your Average Grade

Here are some smart strategies:

1. Focus on high-weight assignments (they influence your average the most)
2. Track your grades weekly
3. Set GPA or percentage goals
4. Use the calculator to simulate “what-if” scenarios
5. Always double-check weight distributions

Common Mistakes in Grade Calculation

• Forgetting to convert weights into percentages
• Mixing up points and percentages
• Not including all assignment types (e.g., participation)
• Misinterpreting weighted averages as unweighted
