How It Works
Your final course grade is a weighted average of your current grade and your final exam score. This calculator solves for the exam score you need.
The basic rule:
- Formula: Needed = (Desired − Current × (1 − Weight)) / Weight
- If the result is 100% or less, your target grade is achievable
- If the result is over 100%, you'd need extra credit or a different target
- The higher the final exam weight, the more it can change your grade — both up and down
This assumes your current grade accounts for all work except the final exam, and that the final exam weight is what your syllabus states. If you have other pending assignments, factor those in first.
Tips & Considerations
- Double-check your current grade before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both grade needed on final and feasibility — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to plan your education.
- If you're unsure about your desired grade, start with a conservative estimate and adjust from there.
Frequently Asked Questions
How is the needed grade calculated?
The formula is: Needed Grade = (Desired Grade − Current Grade × (1 − Final Weight)) / Final Weight. For example, if you have an 80%, want a 90%, and the final is worth 30%, you need: (90 − 80 × 0.70) / 0.30 = 113.3%, which is not achievable.
What if I need more than 100% on my final?
If the calculator shows you need more than 100%, your desired grade isn't achievable through the final exam alone. You may need to lower your target grade or check if extra credit is available.
What does the final exam weight mean?
Final exam weight is the percentage of your total course grade that the final exam counts for. A 20% weight means the final is 20% of your total grade and your other coursework is 80%. Check your syllabus for this value.
Can I use this for midterms too?
Yes! Enter your grade before the midterm, the midterm's weight percentage, and your target grade. The formula works the same for any weighted exam.
What if my class uses points instead of percentages?
Convert to percentages first. Divide your earned points by total possible points and multiply by 100. For the final weight, divide the final's point value by the total course points.
