Weighted Grade Calculation and Final Exam Score Planning
Grade Calculator
How Are Weighted Grades Calculated?
A weighted grade is calculated using the scores and weights of individual assessment components. Multiply each score by its corresponding weight, add the weighted scores, and divide the total by the sum of the weights for components with valid scores. The formula is: Weighted Overall Grade = Σ (Valid Component Score × Component Weight) ÷ Σ Weights of Components with Valid Scores. For example, if exams account for 70% and assignments account for 30%, with an exam score of 90 and an assignment score of 80, the weighted grade is 87.
What If the Total Weight Is Not 100%?
The calculator normalizes the weights of components with valid scores, so the total weight included in the current calculation does not have to equal 100%. The page displays the total weight of components currently included. If the total is below 100%, some assessment components may still be incomplete. If it exceeds 100%, check whether the course weighting has been entered correctly. Only components with valid scores are included; components without scores do not affect the current overall grade.
How Should I Enter Components Without Grades Yet?
You can add final exams, assignments, or other assessment components in advance, enter their names and weights, and leave their scores blank for now. Components without scores are excluded from the current weighted overall grade, the count of components with grades, and the grade contribution breakdown. Once a score is available, enter it and the calculator will automatically include that component in the overall calculation. This lets you keep the complete course grading structure while accurately checking your progress based on completed assessments.
How Do I Calculate the Final Exam Score I Need?
Target grade planning can estimate the final exam score required to reach 60, 80, 90, or a custom target grade. The calculation uses components with entered scores as the current grade baseline and a final exam weight entered separately in the target planner. If the required score is 0 or lower, you have already secured the target even with a final exam score of zero. If the required score exceeds 100, the target cannot be reached even with a perfect final exam score. Note that the final exam weight in the target planner is entered separately; it is not automatically detected from the final exam component in the component list. To avoid double counting, leave an upcoming final exam component blank so it is excluded from the current grade calculation, then enter its weight separately in the target planner. If the final exam component already has a score, it is treated as a completed assessment and should not also be entered as a pending exam weight.
How Should I Enter Coursework, Assignments, and Exams?
You can add assignments, class participation, attendance, lab work, midterm exams, and final exams as separate assessment components, then enter their weights according to your course grading policy. The tool provides four templates: university courses, exams, high school courses, and custom. These templates quickly generate common grading structures, and you can also add or remove components yourself. The higher a component's weight, the greater its impact on the weighted overall grade. Components without scores can be left blank until the grades are available.
How Do I Read the Grade Results?
The results section displays the current weighted overall grade, letter grade, total weight of components included in the calculation, and number of components with entered scores. It also lists the grade contribution of each included component. Each contribution is calculated according to that component's share of the total weight of all components with valid scores. Components without scores are excluded from the current overall grade and contribution breakdown. The page indicates which components still need scores so you can identify incomplete assessments.
How Are Letter Grades Assigned?
The tool uses built-in grade boundaries for the current score: A for 90 or above, B for 80–89, C for 70–79, D for 60–69, and F for below 60. These boundaries are provided for quick reference and do not represent the official grading standards of every school or course. Always refer to the grading rules published by your institution.
Are My Data Saved?
Grade calculations are performed locally in your browser, so course grades do not need to be uploaded. The page saves assessment components, scores, weights, and target grade settings as a local draft in the current browser, allowing you to continue after refreshing the page. Use the Clear Draft function to delete locally saved data. The Reset function restores the default example components.
Frequently Asked Questions
Can I use a course template? Yes. The tool provides four templates: university courses, exams, high school courses, and custom. They quickly fill in common assessment components and weights, which you can then adjust to match your course requirements.
Can I leave a component's score blank? Yes. Components without scores are excluded from the current weighted overall grade, the total weight of valid components, and the grade contribution breakdown. Enter a score when it becomes available, and the component will automatically be included in the calculation.
What should I consider when calculating a target final exam score? The final exam weight in the target planner must be entered separately. It is recommended that you leave an upcoming final exam component blank so it is excluded from the current grade calculation, then enter its weight in the target planner. If the final exam component already has a score, treat it as a completed assessment and do not count it again as a pending exam weight.
Do I need to recalculate after changing a score or weight? No. The results and local draft update automatically when you change a component name, score, or weight.
Are my grade data uploaded? No. Scores and weights are processed locally in your browser, and the draft is saved in the current browser.

What Is Your Weighted Overall Grade?
Add exams, assignments, participation, and other assessment components, then enter their scores and weights to calculate your current weighted overall grade, letter grade, and each component's contribution. Components without scores are excluded from the current total. You can also choose a target of 60, 80, 90, or a custom grade and estimate the final exam score required using a separately entered final exam weight.
