Find the score you need on your final
Enter your current overall grade, your target overall grade, and the final exam weight, all as percentages. This calculator assumes the final exam is the only remaining component of the course. Your current overall grade must describe the completed portion of the course before the final is added. Check your syllabus or gradebook for the actual weight: entering 40 means the final supplies 40% of the course total, not 40 points added to the current grade.
The weighted-grade formula
The completed work contributes current grade × (1 − final weight as a decimal) to the final course grade. The exam contributes exam score × final weight as a decimal. To reach a target, the required exam score is (target grade − current contribution) ÷ final weight as a decimal. The result is a percentage score on the exam. This calculation does not convert letter grades or calculate a GPA.
Checked example
Suppose your current grade is 80%, you want an 85% course grade, and the final is worth 40%. Your completed work contributes 80 × 0.60 = 48 course points. The target needs another 85 − 48 = 37 course points from the final. Dividing 37 by 0.40 gives 92.5%. Check: 80 × 0.60 + 92.5 × 0.40 = 48 + 37 = 85. If a different remaining assignment also affects the course grade, include it in your planning separately; this single-exam result will no longer describe the full situation.
When the target is already met or out of reach
A mathematical result below zero means that a 0% final would still meet the target. The calculator shows 0% as the minimum required score, although the underlying formula may be negative. A result above 100% means the target cannot be reached with a standard 0–100% final alone. Extra credit or another remaining component could change that conclusion, but those are outside this model. Current and target grades must each be between 0% and 100%; final weight must be greater than 0% and at most 100%.
For a different kind of numeric summary, the descriptive statistics calculator can summarize a list of assignment scores. It does not account for course weighting, so use this final-grade calculator for your exam target.
Frequently asked questions
Can I use this for several remaining assignments?
Only if you first combine them into one effective component with a known weight and score. Otherwise, their separate weights require a different calculation.
What does a result above 100% mean?
Under the entered weights, even a 100% final cannot reach your target. Review the inputs and any course policies on extra credit.
Is my current grade already weighted?
Enter the average for completed work before the final. The calculator applies the remaining-course weight to that average.
