Grade Calculator
Calculate weighted class grades from each assignment category, then estimate the score you still need on ungraded work or a final exam to hit your target course grade.

Methodology
Computes weighted average from assignment scores and weights, then solves for the score needed on remaining work to reach a target grade.
Limitations
Grading policies vary by school and instructor. Confirm weighting rules with your syllabus.
How to Calculate a Final Grade
Calculate weighted class grades from each assignment category, then estimate the score you still need on ungraded work or a final exam to hit your target course grade.
Method used
The calculator converts each component score to a percentage, multiplies it by that component's weight, and compares completed weighted work with the target grade.
Weighted score = (score / max score) x component weight
Practical example
If homework is 40% of the grade and exams are 60%, the calculator combines each weighted score and estimates what is needed on ungraded work.
- Homework: 92 out of 100, weight 40%
- Midterm: 84 out of 100, weight 30%
- Final exam: blank score, weight 30%
The result shows the current weighted grade and the score needed on remaining components to reach the target.
Assumptions
- Weights are entered as percentages of the final grade.
- Blank scores represent ungraded or future work.
- A complete class grade should have weights totaling 100%.
What this includes
- Weighted components, custom max scores, blank future scores, target grade, and weight-total warning.
What this excludes
- Instructor curves, extra credit policies, dropped assignments, attendance rules, and school-specific grade scales.

Frequently Asked Questions
How does a weighted grade calculator work?
It multiplies each graded component’s score by its weight percent, adds those weighted contributions, and compares completed work against your target final grade. Blank future items keep their weight available so the tool can solve for the average you still need. Match weights to your syllabus exactly—homework, quizzes, projects, and exams often differ.
What does a blank score mean?
A blank score represents a future or not-yet-graded component such as a final exam or pending project. The calculator uses those remaining weights to estimate the minimum average score required on unfinished work. Leave completed items filled and upcoming ones blank so the projection stays accurate as new grades post.
What if the weights do not add up to 100%?
Weights should add up to 100% for a complete course grade scheme. The calculator flags totals that do not add to 100 so you can fix typos before trusting the needed-score estimate. Extra credit policies and dropped scores may need manual syllabus interpretation beyond a simple weight table.
How do I find what I need on the final exam?
Enter all graded categories with their weights and scores, leave the final exam weight blank or unscored, and set your target course grade. The tool solves for the exam score that would reach that target given remaining weight. If your final is capped or curved, treat the result as a planning lower bound, not a guarantee.
Do dropped scores or curves change the result?
Yes. If your instructor drops the lowest quiz or curves exams after grading, a raw weighted average can differ from the syllabus outcome. Model the course as your instructor will compute it—omit dropped attempts or use post-curve scores when known. When policy is unclear, ask your instructor rather than relying only on an online estimate.
