Final Grade Calculator
Find exactly what score you need on the final exam to hit your target letter grade for the class. Breakpoints for A, A-, B, C, and D shown side by side.
ACADEMICCalculate the exact score you need on the final exam to hit a target letter grade for the class. Shows breakpoints for A, A-, B, C, and D side by side so you can plan your study effort.
Solves the weighted-average equation: (target - current_grade * (1 - final_weight)) / final_weight = needed score. Returns "impossible" if the result exceeds 100 and "already locked in" if you would pass even with a zero on the final. Verdict label (comfortable / tight / risky / extreme / impossible) summarizes how realistic each target is.
Disclaimer: Assumes the final is the last remaining assignment graded out of 100. Some schools use +/- thresholds that differ from the defaults shown - check your syllabus for exact cutoffs.

Frequently Asked Questions
What score do I need on the final to pass my class?
Solve: (target_grade - current_grade × (1 - final_weight)) / final_weight = score needed on final. If you have 70% in class and the final is worth 30%, to pass with a 60% you need (60 - 70 × 0.7) / 0.3 = 36.7% on the final. The calculator does this automatically and shows breakpoints for every letter grade.
Is it mathematically possible for me to get an A?
Plug your numbers into a target-grade calculator. If the required score on the final exceeds 100, an A is impossible at the current final weight. The lower your current grade and the smaller the final's weight, the harder a late comeback becomes. A 75% current grade with a 20% final cannot reach an A no matter what you score on the final.
How should I prioritize my studying if multiple finals are happening?
Rank your finals by (current_grade_gap_to_target) / (final_weight × hours_to_study). Focus first on classes where small improvements move you across a grade boundary (an 89% → 90% jump in a class with a heavy final pays off more than studying a class you have already locked in). Diminishing returns kick in past 4-5 hours per subject in a single sitting.
