Weighted Grade Calculator
Calculate your final class grade based on assignments and exam weights.

Many courses do not treat all assignments equally — a final exam might be worth 40% of your grade while homework counts for only 20%. This calculator lets you enter your actual scores alongside their syllabus percentage weights to find your true overall class grade. It handles any weight combination, including cases where your current weights do not yet sum to 100%, making it equally useful for checking your standing mid-semester as it is for calculating your final grade at the end of a course. To use it effectively, locate your course syllabus and note the percentage weight assigned to each category such as homework, quizzes, midterms, and the final exam. Consolidate all homework and participation scores into a single average score and enter it alongside that category's total weight. The result is your current weighted percentage, which you can map to a letter grade using your institution's grading scale. This approach removes the guesswork from grade tracking and lets you calculate the minimum score needed on a remaining assignment to reach your target final grade, giving you a clear and actionable picture of where you stand in the course.
How It Works
The calculator multiplies your assignment score by its weight and your exam score by its weight, then sums the two products: (assignmentScore × assignmentWeight) + (examScore × examWeight). This sum is divided by the total weight (assignmentWeight + examWeight) to produce your final weighted grade percentage. Dividing by the actual total weight — rather than assuming 100 — ensures the calculation works correctly even mid-semester when only some components are graded and weights do not yet sum to 100. For example, if you have only completed assignments worth 60% and an exam worth 40%, entering both gives a total weight of 100 and a standard result. If you have only completed the assignments so far (weight 60), the calculator divides by 60, correctly reflecting your standing on the portion of the course graded to date rather than penalizing you for the exam you have not yet taken.
