What this final grade calculator does
A final grade calculator tells you the mark you need on the final exam to finish a course at your target grade — and flags when that target is already secured or no longer possible.
The formula
needed = (target − current × (1 − weight)) ÷ weight
where weight = final exam's share of the grade (as a decimal)
If your current grade is 88%, you want 90% overall, and the final is worth 30%, you’d need about 94.7% on the final.

Final Grade FAQ
What do I need on my final exam?
Enter your current grade, your target overall grade and the final's weight. The calculator rearranges the grade formula to show the exact score you need.
How is the needed score calculated?
Using needed = (target − current × (1 − weight)) ÷ weight. For a current 88%, a 90% target and a 30% final, you'd need about 94.7%.
What if the score needed is over 100%?
Then that target isn't reachable from the final alone. The calculator shows the best overall grade you can still get by acing the final.
What if it says I need 0% or less?
You've already locked in your target — even a zero on the final keeps you at or above it.
What counts as my "current grade"?
Your weighted average on everything except the final. The final's weight is its share of the overall grade, from your syllabus.
