Final Grade Calculator
This free final grade calculator tells you exactly what score you need on your final exam to reach the course grade you want. Enter your current grade, the weight your final (or midterm) carries, and your target grade, and the calculator instantly shows the minimum score you need. It is the fastest way to answer the question every student asks before finals week: "What do I need on my final to get an A — or just to pass?"
How to Use the Final Grade Calculator
- Enter your current grade — your percentage in the course before the final.
- Enter the final exam weight — how much it counts toward your total grade.
- Enter your desired course grade.
- Calculate — see the score you need on the final.
The Formula
Required Final Score = (Target − Current × (1 − Final Weight)) ÷ Final Weight
For example, if your current grade is 85%, your final is worth 30%, and you want an 80% overall: (80 − 85 × 0.70) ÷ 0.30 = (80 − 59.5) ÷ 0.30 = 68.3%. You only need about 68% on the final to keep your B.
Required Score by Current Grade
| Current Grade | Final Worth 30%, Target 80% |
|---|---|
| 90% | 57% needed |
| 80% | 80% needed |
| 70% | 103% (not achievable) |
What If You Need More Than 100%?
If the calculator says you need more than 100% on your final, your target grade is not reachable through the final alone. Lower your target to a grade that is achievable, ask your professor about extra credit, or focus on maximizing the grade you can realistically earn. This same final exam grade calculator also works for a midterm — just enter the midterm's weight instead.
Why Use a Final Grade Calculator?
- Know exactly how hard to study based on what's actually needed.
- Avoid panic — sometimes a modest score secures your grade.
- Spot early when a target is out of reach so you can adjust.
- Plan study time across multiple courses by priority.
Frequently Asked Questions
What do I need on my final to pass?
Enter your current grade, your final's weight, and the minimum passing grade (often 60% or 70%). The calculator shows the exact score you need on the final to pass.
What is the formula for the final grade?
Required Final Score = (Target − Current × (1 − Final Weight)) ÷ Final Weight. It solves the course-grade equation backward to find the score you need.
Can I use this as a midterm grade calculator?
Yes — enter the midterm's weight in place of the final's weight, and it works exactly the same way.
What if I need over 100% on the final?
Your desired grade is not achievable through the final alone. Lower your target, seek extra credit, or aim for the best realistic grade instead.
