Final Grade Calculator
PopularCalculate what score you need on your final exam to get your desired course grade — or predict your overall grade.
"What do I need on the final?" is one of the most searched student queries every December and May. Enter your current course grade, final exam weight, and target grade — instantly see the score required. Switch to predict mode to see your overall grade if you score X on the final.
Extremely seasonal but dominant traffic during finals week. Low competition when the tool is fast, mobile-friendly, and answers both directions (needed score + prediction). Students share these links in group chats every semester.
Formula: Required final = (Target − Current × (1 − FinalWeight)) ÷ FinalWeight. Handles edge cases where the target is already achieved (you need 0% or less) or mathematically impossible (required score above 100%).
Example: 85% current grade, 40% final weight, want 90% overall → you need (90 − 85×0.6) / 0.4 = 97.5% on the final. If that feels unreachable, try predict mode to see outcomes for 80%, 85%, or 90% on the exam.
Free, no login. Confirm final weight with your syllabus — some courses weight homework, midterms, and finals differently than a simple two-component model.
Formula
Score needed = (Desired grade − Current grade × (1 − Final weight)) ÷ Final weight · Predicted grade = Current × (1 − w) + Final score × w
