The Formula
Required final = (Target − Current × (1 − Final weight)) ÷ Final weight
Understanding the Final Exam Grade Calculator: What Score Do I Need?
Example: a current average of 85%, a target of 90%, and a final worth 30% require 101.67% on the final. Without extra credit, that target is out of reach.
A negative required score means the target is already secured with a zero on the final, assuming no minimum exam requirement. The current average must exclude the final; do not use a gradebook average that already counts a missing final as zero.
A second example: an 85% current average and a final worth 30% require 68.33% on the final to finish with 80%. A 90% target instead requires 101.67%. Enter the numeric cutoff from your syllabus rather than assuming that every US school uses 90% for an A.
Frequently Asked Questions
Does my school use the same grading rules?
Check your syllabus or registrar policy. Rounding, extra credit, repeated courses and pass/fail exclusions vary. These results are planning estimates.
Does this round the required exam score for my school?
No. The displayed result rounds to two decimals for planning. Check whether your instructor rounds course grades, enforces minimum exam scores, or offers extra credit.
