Final Grade Calculator
Find out exactly what score you need on your final exam to reach the course grade you want — and see your resulting grade. Updates live as you type; nothing is stored.
How it works
Your course grade is a weighted average: the work you've already done counts for part of it, and the final exam counts for the rest (its weight). To hit a target overall grade, the final must make up the gap. This calculator rearranges the weighted-average formula to tell you the exact score you need on the final, and also shows the best grade you could still reach (if you scored 100%). If the required score is above 100%, the target isn't reachable with the final alone; if it's 0 or below, you've already secured it. Everything runs in your browser — nothing is stored.

Frequently asked questions
How do I calculate the grade I need on the final?
The required final score is (target − current × (1 − weight)) ÷ weight, where current is your grade so far, target is the overall grade you want, and weight is how much the final is worth (as a fraction). This tool does it for you as you type.
What if the required score is over 100%?
If the number is above 100, it is not possible to reach that target with this final alone — you would need extra credit or a higher score than the exam allows. The tool flags this so you can set a realistic goal.
What if it is 0% or negative?
A result of 0 or below means you have already secured your target grade — even a zero on the final would keep you at or above it.
Does it store my grades?
