Formula: Required Final Exam Grade = (Target Grade - (Current Grade × (1 - Final Weight))) / Final Weight (where weight is a decimal).
Throughout a school semester, it is common to wonder exactly what score you need on your final exam to secure a specific target grade in a course.
The Grade Calculator handles this math for you by asking for your current overall grade, your desired final course grade, and how much weight (in percentage) the final exam carries.
By understanding operator weight and calculating the weighted average backwards, you can set realistic expectations and manage your study efforts for finals week.
Our tool provides immediate feedback, allowing you to run what-if scenarios: what happens if the final is worth 20% versus 30%, or if you decide to settle for a B instead of an A?
This utility is perfect for high school and university students who want an accurate, simple dashboard to audit their class standings.

Answers to help you use the calculator correctly.
This means that even with a perfect score (100%) on the final exam, your current grade is too low to reach your target grade. You would need extra credit to achieve it.
A negative result means you have already locked in your target grade. Even if you get a zero on the final exam, your grade will remain above your target.
This calculator is for a single overall grade and a final exam weight. If you need to average categories (e.g. homework, quizzes, tests), calculate your weighted average first to find your current grade, then use this tool.
