Final grade calculator
Use our final grade calculator when you’re asking, “What do I need on the final?” Enter your current grade, desired grade, and final exam weight to instantly see the required final score—shown as a percentage and a letter grade using your selected grading scale. For teachers and power users, the built-in batch planner accepts pasted CSV/XML rows so you can compute the needed-on-final for multiple students at once and download results—fast, accurate, and stress-free.
Calculate Final Grades
This final grade calculator tells you exactly what score you must earn on the final exam to reach a target overall grade. Provide your current grade (percent or letter), the final exam weight (percent), and your target grade. We apply a weighted average to compute the required final exam percentage. If the result is above 100%, it means you’ll need extra credit, a curve, or different grading policies to hit that target.
Example table (inputs → required final exam grade):
| Current grade (c) | Final exam weight (w) | Target grade (t) | Required on final |
| 70% | 0.50 (50%) | 80% | 90% |
| 87% | 0.60 (60%) | 90% | 92% |
Formula (use weight as a decimal, e.g., 50% = 0.5):
Required Final Exam Grade = ( t − (1 − w) × c ) ÷ w
Worked example
- c = 70%, w = 0.5, t = 80%
- Required = (80 − (1 − 0.5) × 70) ÷ 0.5
- Required = (80 − 35) ÷ 0.5 = 45 ÷ 0.5 = 90%
Why Use a Final Grade Calculator?
A grade calculator gives instant clarity on where you stand, highlights strengths and weaknesses, and removes manual math errors. It saves time so learners can focus on studying, supports multiple grading systems (percentage, letter, GPA), and helps you plan smarter with real exam weightings from your syllabus.
Limitations of Final Grade Calculators
Results depend on accurate inputs (weights, scores). Rounding rules, curves, or mid-term policy changes may shift the final outcome. Treat the output as a planning guide—always confirm the grading scale and rules your instructor uses.
FAQ
What Grade Do I Need on My Final?
Find which grade you need on your final exam using this simple formula:
Required Final Exam Grade = (Target Grade − (1 − Final Exam Weight) × Current Grade) ÷ Final Exam Weight
Example:
If your current grade is 70%, the final exam weight is 40%, and your target grade is 95%,
then:
Required = (95 − (1 − 0.4) × 70) ÷ 0.4 = 132.5%
That means you would need extra credit to reach your target of 95%.
If you find manual calculations confusing, use an online Final Grade Calculator — it will instantly compute the exact score you need to achieve your desired result.
How Can I Predict the Grades I Need to Achieve a Desired Final Grade?
Find your current course grade.
Check how much the final exam is worth.
Set your target grade.
Then, use a Final Grade Calculator to instantly see what score you need — or calculate it manually using the formula:
Required Final = (Target Grade − (1 − Final Exam Weight) × Current Grade) ÷ Final Exam Weight.
Both methods will help you determine the exact score you need to reach your desired result.
Can a Single Low Score Significantly Impact My Overall Grade?
A single low score does not affect your overall grade very much if that test or assignment has a low weight. But if the low score is on something with a high weight — like a major assignment, quiz, midterm, or final exam — then it can pull your total grade down significantly
How Do Professors Determine the Weight for Each Assignment or Exam?
Some universities or schools have a fixed grading policy that instructors must follow. However, in other institutions, teachers have the flexibility to decide the grade weights based on the course type. For example, they might assign a higher percentage to the final exam and a lower weight to assignments or quizzes.
