Final Grade Calculator
Enter your current grade and how much your final is worth to see the exact score you need to finish with the grade you want.
Score at least 94.67% on your final to finish with a 90% overall.
How the final grade calculator works
Your overall grade is a weighted average of the work you've already done and your final exam. If your final is worth w (as a fraction) and your current average is C, then to reach a target T you need:
Required final = (T − C × (1 − w)) ÷ w
For example, with an 88% going in, a final worth 30%, and a target of 90%, you'd need about a 94.7% on the final.
Tips before your final
- Check your syllabus for the final's exact weight — it's often 20–40%.
- Use your true current average, not a single test score.
- If the number you need is impossible, ask early about extra credit or curves.
Frequently asked questions
How do I calculate what I need on my final?
Enter your current grade, how much the final is worth (its weight), and the overall grade you want. The calculator solves: required final = (target − current × (1 − weight)) ÷ weight.
What if the score I need is over 100%?
That means your target isn't reachable with this final alone — the final simply isn't weighted heavily enough. Try a lower target, or ask your instructor about extra credit.
What if I already have the grade locked in?
If the calculator shows you need 0% or less, you've already secured your target — even a zero on the final keeps you at or above the grade you want.
Is my current grade the same as my final's weight?
No. 'Current grade' is your average so far across everything except the final. 'Weight' is how much the final counts toward your overall grade, usually shown in your syllabus.
