Frequently asked questions
Is this final grade calculator free?
Yes. It works instantly in your browser with no signup.
Are the results exact?
Results follow the stated formula, but real-world fees, timing, and rounding can vary.
What score do I need on my final?
Required final = [target − current × (1 − weight)] ÷ weight. If the final is 30% and you have 84% aiming for 90%, you need a 104%—not always possible.
What if I need over 100%?
The target is out of reach with that weight. Talk to the instructor about extra credit or accept a lower target.
Is the current grade weighted?
Enter your current course percent as the teacher shows it, and the final’s weight from the syllabus (for example 20% or 30%).
Can the required score be negative?
If you already exceed the target, the required final can be very low or negative—meaning you can score poorly and still make the target.
