Final Grade Calculator

The Final Grade Formula, Explained

Your course grade is a weighted blend: course = (1 − w) × current + w × final, where w is the final's weight. Solving for the final score gives needed = (target − (1 − w) × current) ÷ w. Example: current grade 82%, final worth 25%, target B (83): needed = (83 − 0.75 × 82) ÷ 0.25 = (83 − 61.5) ÷ 0.25 = 86%. Every point of final weight is leverage — a 35% final can rescue (or sink) a grade far more than a 15% one.

Reference Table: Final Worth 30%

Needed final-exam scores for common situations when the final counts for 30% of the course (A target = 93, B target = 83, pass = 60):

“Secured” means even 0% on the final keeps the target; “not reachable” means over 100% would be required.

Three Things to Check Before You Panic

• The exact weight — syllabi sometimes split “final assessment” into exam + project; use only the exam's share here.
• Drop and replacement rules — a dropped lowest quiz or a final that replaces a bad midterm can move your current grade before the formula applies.
• Rounding policy — an 89.5% often rounds to an A-; if you're within half a point of a cutoff, the needed score is effectively lower than the table shows.
