The final grade calculator finds the percentage score needed on remaining assessments to reach a desired course result. It accounts for the weight of completed work and clearly identifies targets that require more than 100%.
How to use this calculator
Enter your current weighted grade, the percentage of the course already completed, the desired final grade, and the remaining assessment weight. Completed and remaining weights should total 100% for a standard course model.
Formula & calculation method
Required remaining score = (desired − current × completed weight) / remaining weightWeights are converted from percentages to fractions. The current contribution is current grade multiplied by completed weight. The remaining score must supply the difference between the target and that contribution.
Worked example
If your current grade is 82% on 60% of the course and you want 90% overall, the remaining 40% must provide enough points to close the gap. The required score is 102%, so the target is not achievable without extra credit.
Why this is useful
The calculator turns a target into a concrete requirement and warns when the mathematics falls outside a normal 0–100% range. This supports realistic planning before an exam or final project.
Limitations to keep in mind
The model assumes the entered current grade and weights match the syllabus. Extra credit, dropped scores, curves, minimum passing rules, and revised weights can change the actual requirement.
Frequently asked questions
What if the required score is above 100%?
The target is not mathematically achievable under the entered weights without extra credit, a curve, or changed grading rules.
What if the required score is below zero?
You have already secured more than the target under the model, so even a zero on the remaining work would leave you above it.
Must the two weights total 100%?
Yes for a complete course calculation. The calculator warns when they do not, because the inputs would not represent the full grade.
