Final Grade Calculator

The formula is: Required Final Score = (Target Grade − Current Grade × (1 − Final Exam Weight)) ÷ Final Exam Weight. For example, if your current grade is 70%, your target is 80%, and the final is worth 50%, you need: (80 − 70 × 0.5) ÷ 0.5 = 90%.

A required score above 100% means reaching your target grade is mathematically not possible with a standard exam. You may want to lower your target grade or check whether extra credit opportunities are available in your course.

Yes — as long as you know your current grade, your desired final grade, and how much the final exam counts toward your total score, this calculator works for any course at any level.

Check your course syllabus — instructors typically list the weight of every graded component including the final exam. If you can't find it, ask your instructor or teaching assistant directly.

If the final counts as both a test and a final exam, you should factor in the test weight separately. Consider splitting the calculation: first compute what you need under the test weight, then under the final weight, or ask your instructor exactly how the grade breakdown works.

This version uses percentage inputs for maximum precision. To convert letter grades: A=95, A-=92, B+=88, B=85, B-=82, C+=78, C=75, C-=72, D=65, F=50. Enter the corresponding percentage for your current and target grades.

A negative required score means you have already secured your target grade regardless of what you score on the final. You could technically score 0% on the final and still meet your goal, so well done!

Your current grade contribution is the portion of your final course grade already locked in from work completed before the exam. It equals: Current Grade × (100% − Final Exam Weight). The remaining percentage is what the final exam can influence.
