Final grade calculator
In short: enter your current grade and the final's weight to see the score you need for your target grade.
Enter what you have so far and what the final is worth, and see the score you need to hit your target — or what a given final score will leave you with.

You need 95.5% on the final
How the math works
What it does not do
It does not know your school's rounding rules, it does not handle dropped scores or extra credit, and it does not predict what you will actually score. It is one weighted average, written out so you can check it.
Questions
How is the needed score calculated?
Needed = (target − current × (100 − weight)%) ÷ weight%. The steps above show the numbers substituted.
What if I need more than 100%?
The target is out of reach with this final; the page shows the best grade a perfect final could produce.
What if the final is worth 0%?
Then it cannot change your grade, and the page says so instead of dividing by zero.
Does it handle extra credit or dropped scores?
No — it assumes one final with a single weight.
Is my data uploaded?
No; the calculation runs in your browser.
