Grade Calculator | Weighted Grade & Final Exam

Enter your current grade percentage and its weight in the course (e.g., 85% worth 70% of the grade), plus the weight of your remaining final exam. The calculator solves for the exam score you need to hit your target overall grade.

Convert each component to a percentage first: (Points Earned / Points Possible) × 100. Enter that percentage as the grade for each assignment row, along with its weight — add a separate row for each test, homework set, quiz, or participation component.

Common scale: A+ =97-100%, A=93-96%, A-=90-92%, B+=87-89%, B=83-86%, B-=80-82%, C+=77-79%, C=73-76%, C-=70-72%, D+=67-69%, D=60-66%, F=below 60%. Scales vary by institution — check your syllabus for the exact grading breakdown.

Use Final Goal mode. Enter your current grade, current course weight, target grade, and final exam weight. The calculator solves for the minimum score needed on the final to achieve your target grade. If the required score exceeds 100%, it flags it as not achievable.
