This grade calculator computes your overall course grade by calculating a weighted average of your scores across different assessment categories (such as assignments, exams, and quizzes). Select the weight percentage for each category and input your score.
Formula Used
Weighted Grade = Σ (Score × Weight) ÷ Σ (Weight)
Score
— the score received in a grading category (expressed as a percentage)
Weight
— the percentage weight the category contributes to the final grade (e.g. 40%)
Σ (sum)
— the sum of all weighted scores, divided by the total active weights
Example Calculation
Suppose a student has an Exam score of 85 (weighted at 40%) and a Homework score of 90 (weighted at 60%). Weighted Grade = (85 × 0.40) + (90 × 0.60) = 34 + 54 = 88%.
Frequently Asked Questions
A weighted grade means different assessments have different impacts on your final score. For example, a final exam worth 50% affects your grade as much as five homework assignments worth 10% each.
If your category weights do not sum to 100%, the calculator normalises the weights so they proportionally sum to 100% based on the relative weights you entered.
Subtract your current weighted grade from your target course grade, and divide by the weight of the final exam. This tells you the minimum exam score required to achieve your goal.
A grade point is a numeric value (usually 0 to 4.0) assigned to your final letter grade, which is then used to calculate your overall Grade Point Average (GPA).
Convert the score to a percentage first. For example, if you scored 18 out of 25 on a quiz, enter the score as 72% (18 ÷ 25 × 100).
