About the Grade Calculator
Find out what score you need on your final exam to reach the course grade you want.
How to use the Grade Calculator
- Enter your Current Grade (%) and your Desired Grade (%).
- Enter the Final Exam Weight (%).
- Press Calculate Target Score.
Formula and method
Needed score = (Desired − Current × (1 − w)) ÷ w, where w is the final exam weight as a decimal.
Worked example
With a current grade of 85%, a goal of 87% and a final worth 20%: (87 − 85 × 0.8) ÷ 0.2 = (87 − 68) ÷ 0.2 = 95% needed.
When to use the Grade Calculator
- Working out your overall grade from coursework and exams.
- Finding the score you need on a final exam to pass or reach a target.
- Tracking weighted assignments in a term.
Common mistakes to avoid
- Ignoring the weights of each part of the grade.
- Assuming the final exam only needs the same score as your current average.
Tips
- If the needed score is above 100%, your goal may not be reachable without extra credit.
- Ask your instructor how the final is weighted and whether the lowest score is dropped.
Frequently asked questions

How do I calculate a weighted grade?
Multiply each score by its weight, add the results and divide by the total weight.
What score do I need on my final exam?
Enter your current grade, the target grade and the exam's weight, and the tool works out the score required.
