Grade Calculator

What Is a Grade Calculator?

A grade calculator computes your weighted average grade from multiple assignments, quizzes, tests, and exams. Each assignment can have a different weight reflecting its importance in your final grade. This tool helps you track your current standing in a course and plan how to achieve your target grade by understanding how each component contributes to your overall score.

Weighted Grade Formula

The weighted average formula calculates your grade based on each component's contribution:

Weighted Grade = Σ(Score × Weight) ÷ Σ(Weight)

Where Score is the percentage earned on each assignment and Weight is the relative importance assigned to that component. The denominator is the sum of all weights included in the calculation.

Example Calculation

Example: Calculating Course Grade

Assignments:

• Homework (weight: 20): 92%

• Midterm Exam (weight: 30): 78%

• Project (weight: 15): 88%

• Final Exam (weight: 35): 85%

Calculation:

Weighted Sum = (92×20) + (78×30) + (88×15) + (85×35) = 1840 + 2340 + 1320 + 2975 = 8475

Total Weight = 20 + 30 + 15 + 35 = 100

Final Grade = 8475 ÷ 100 = 84.75%

Limitations and Notes

Curved grades or adjusted scoring must be entered as the final adjusted percentage.
Letter grade conversions depend on your course's specific grading scale.
Some instructors drop lowest scores—factor this in when entering grades.

Frequently Asked Questions

How do I calculate my weighted grade?▼

To calculate a weighted grade, multiply each grade by its weight, sum all weighted grades, then divide by the total weight. For example, if homework (weight 20) is 85%, midterm (weight 30) is 78%, and final (weight 50) is 90%: (85×20 + 78×30 + 90×50) ÷ 100 = 85.4%.

What is the difference between points mode and percentage mode?▼

Points mode lets you enter raw scores and maximum possible points (e.g., 45 out of 50), then the calculator converts to percentage. Percentage mode assumes you already have the percentage score. Use points mode when your syllabus shows assignments with point values.

Do all assignment weights need to add up to 100?▼

No, weights don't need to total exactly 100. The calculator uses relative weights, so if you enter weights of 10, 20, and 30, it calculates as proportions of the total (60). This is useful when you haven't completed all assignments yet.

How do I calculate my grade if some assignments aren't weighted?▼

If assignments have equal weight, assign them all the same weight value (like 1 or 10). The calculator will average them equally. For unweighted categories, use the same weight for each item in that category.

Can I calculate my grade without the final exam?▼

Yes, simply leave out the final exam or any incomplete assignments. The calculator computes your current grade based on entered assignments only. To find what you need on the final, use our Final Grade Calculator.

What if my course uses a different grading scale?▼

This calculator computes percentage grades, which are universal. After getting your weighted average percentage, compare it to your course's grading scale. Common scales: A=90-100%, B=80-89%, C=70-79%. Check your syllabus for specific cutoffs.
