Enter your current grade, the final exam's weight toward the overall grade, and your target grade - the score you need on the final updates as you type. The calculation also works in reverse: enter a hypothetical final score instead of a target, and the resulting overall grade is shown below it, so you can check a few "what if I score X" scenarios before exam day without doing the arithmetic by hand.
Final Grade Calculator
The final grade calculator answers the question directly: enter your current grade, how much the final exam counts toward the overall grade, and your target grade - the score you need on the final updates as you type, entirely in your browser.
Key features
- Solves the weighted-average algebra for the score needed on the final to hit a target overall grade, and flags when the target is already locked in or out of reach this term.
- A reference table maps a range of hypothetical final scores (0 to 100%) to the resulting overall grade at the current grade and weight entered.
- Runs entirely client-side - nothing you type is stored or sent anywhere, and no account is needed.
The algebra behind it
Overall grade equals the current grade times its share of the total, plus the final score times the final's weight. Solving that equation for the final score - rather than averaging grades you already know - is what makes this a different calculation from a course-wide GPA.
| Current grade | Final weight | Target | Score needed on the final |
|---|---|---|---|
| 85% | 30% | 90% | over 100% (not reachable) |
| 85% | 30% | 87% | 91.7% |
| 78% | 20% | 80% | 88.0% |
This is plain weighted-average arithmetic on the numbers you enter, not a substitute for a syllabus's official grading policy - rounding, curves, extra credit and dropped-lowest-score rules vary by course. For other grade math on this site, the GPA calculator averages per-course grades you already have, weighted by credit hours, across a whole semester; this page instead solves for one still-unknown exam score in a single course.
Frequently Asked Questions
What does the final grade calculator do?
It solves for the score you need on a final exam to reach a target overall grade, given your current grade and how much the final counts toward the overall grade. It also works in reverse - enter a hypothetical final score and see the overall grade it produces.
How is this different from the GPA calculator?
The GPA calculator averages grades you already have across multiple courses, weighted by credit hours. This tool solves a single-course algebra problem for one still-unknown exam score - a different question the GPA calculator cannot answer.
What does it mean if the score needed is over 100%?
It means the target grade is not reachable this term - even a perfect 100% on the final would not be enough. The result also shows the highest overall grade a perfect final score would produce, so you can see how close a perfect score gets you.
Is my grade data sent anywhere?
No. The calculation runs entirely in your browser - nothing you type is stored or sent to this site's servers or anywhere else, and no account is needed.
