How this final grade calculator works
The calculator weighs your current grade by the non-final portion of the course, then solves for the final exam score needed to reach the desired overall grade.
Impossible and already-reached cases
A result over 100% means the desired grade is not reachable with a normal 0 to 100 final score under the entered assumptions. A result below 0% means the desired grade is already reached by the formula.
What this calculator does not include
This tool does not model curves, dropped assignments, category rules or extra credit unless those are already reflected in the current grade you enter. Grading systems vary by school.
Key terms and assumptionsShort notes about current grade, desired grade, final exam weight and course-specific rules.
- Final grade formula
- The calculator solves for the final exam score needed after weighting current grade and final exam weight.
- Final exam weight
- Final exam weight must be greater than 0 and cannot be more than 100%.
- Zero grades
- A current grade or desired grade of 0 is valid. Blank required fields are not treated as 0.
- Over-100 grades
- Current or desired grades over 100% are allowed up to a practical cap and labelled as extra-credit assumptions.
- Course rules vary
- This tool does not model curves, dropped work, category rules or every syllabus policy.

FAQs
How do I calculate the score needed on a final?
The calculator weighs your current grade by the non-final portion and solves for the final exam score needed to reach your desired grade.
What if the result is over 100%?
That means the desired grade is not reachable with a normal 0 to 100 final score under the entered assumptions.
What if the result is below 0%?
That means the desired grade is already reached mathematically under the entered assumptions.
Should I include extra credit?
Include extra credit only if it is already reflected in your current grade or your instructor's grading rules.
Does this work for weighted categories?
It works when your current grade already represents all non-final work and the final exam weight is known.
Can I enter decimals?
Yes. Decimal grades and weights are supported.
Why might my course grade differ?
Syllabi can include dropped scores, category rules, curves and grading policies that this simple formula does not model.
