What Grade Do I Need on My Final?
Solves the weighted-course equation for the final exam score required to reach a target overall grade.
Limitation: Verify that your current grade excludes the final and that the syllabus uses a simple weighted model.
How to Calculate the Grade Needed
This page serves the final-exam intent specifically. For assignment averages, category weights, or GPA, use the broader grade and GPA calculators.
Find your current grade for completed coursework before the final exam.
Avoid double-counting the final
Your current grade should describe completed work only. If the learning system already treats an ungraded final as zero, recalculate the pre-final average first.
Interpreting the Required Score
The calculator separates the target grade into the contribution already supplied by completed work and the contribution required from the final. A result above 100% means the target cannot be reached through the final alone under this model. A result below 0% means the target is already secured even with a zero on the final, though attendance or minimum-exam rules may still apply.
Final Grade Examples
Reach 85% with a 30% final
Current, target, and weight
Required final score
Completed work contributes 57.4 points; the final must contribute 27.6 points, which is 92% of its 30-point weight.
Target outside the reachable range
Current, target, and weight
Required final score
The mathematical result is above 100%, so the target is not reachable through this final alone.
Plan with the unrounded requirement
Aim above the displayed threshold when your institution rounds only the final course grade.

Try the CalculatorFinal Exam Grade Formula
The weighted-course equation is rearranged to isolate the unknown final score.
Formula
Weighted course grade
target = current × (1 − final weight) + final score × final weight
Required final score
required = (target − current × (1 − final weight)) ÷ final weight
Scientific Background
This is a linear weighted-average model. It is exact when the pre-final grade represents all non-final work and the final has one stated percentage weight.
