Combine assignments, midterms and finals into one overall grade.
Overall Grade
77.6%
Letter grade: B+
Most courses don't grade you on a single number โ they combine assignments, quizzes, a midterm, and a final exam, each worth a different percentage of your overall grade. This calculator adds up those weighted components into one overall percentage, and shows the corresponding letter grade.
Add each component with its score and its weight (how much of the final grade it's worth), and the tool handles the weighted maths for you.
Formula
Overall % = ฮฃ(Component Score % ร Component Weight %) รท ฮฃ(Weights)
Each component's weight should reflect your course syllabus exactly โ check it if the numbers look off.
Worked Example
Worked example
Weights should add up to 100%
For an accurate result, your component weights should sum to 100% (matching your syllabus exactly). If your course has extra credit or dropped-lowest-score rules, those need to be applied to your raw scores before entering them here, since this calculator doesn't automate syllabus-specific exceptions.
Working backwards from a target grade
If you already know some of your component scores and want to know what you need on a remaining component (like the final exam) to hit a target overall grade, use the Final Grade Calculator instead โ it solves specifically for that missing number.
Frequently Asked Questions
How do I calculate my overall grade with different weighted components?
Multiply each component's score by its weight percentage, add all of those up, then divide by the total of the weights (which should be 100 if your weights are already percentages).
What if my weights don't add up to 100%?
Double-check your syllabus โ component weights should sum to 100% for the calculation to represent your true final grade accurately.
Can this tell me what score I need on my final exam?
This tool calculates your grade from known scores. To solve backwards for a required final exam score, use the dedicated Final Grade Calculator.
