It is not possible to ensure the final grade you want even if a A+ is attained for all the remaining tasks.

You can get the final grade you want even if you got F for all the remaining tasks.

Minimum grade you need for all the remaining tasks to get the final grade you want: 81.33

What Is This Tool?

The Grade Calculator has two modes. Average grade takes your assignments and exams, each with a grade and a weight, and returns your weighted overall grade as a letter and value. Final grade works backward: enter your current grade, the grade you want, and how much the final is worth, and it tells you the minimum score you need on that final. Grades can be entered as percentages or letters, and the tool converts between them on a standard 4.0 scale.

How to Use This Tool?

  • Pick the average grade or final grade mode.
  • Enter each item with its grade and weight.
  • For a final, enter current, target, and final weight.
  • Click Calculate to see your result.

Key Features

  • Weighted average from any number of items.
  • Tells you the score needed on a final exam.
  • Accepts both percentage and letter grades.
  • Add or remove assignment rows as you go.
  • Shows the result as a letter and a value.

Examples

  • Homework (90, 5%), Project (B, 20%), Midterm (88, 20%) averages to about B.
  • Two items at 80% and 90% with equal weight average to 85%.
  • With an 88 current grade, an 85 target, and a 45% final, you need about 81 on the final.
  • If the needed final score is below zero, you have already reached your target.

Common Use Cases

  • Tracking your current grade partway through a course.
  • Seeing what you need on a final to pass or reach a target.
  • Combining weighted assignments, quizzes, and exams.
  • Mixing letter and percentage grades in one calculation.
  • Planning study effort around what each grade requires.

Tips & Best Practices

  • Make sure your weights reflect the syllabus, ideally totaling 100%.
  • Enter grades consistently as either percentages or letters.
  • Use the final grade mode early to set a realistic target.
  • Leave a row blank to exclude work you haven't done yet.
  • Check your syllabus, since grade cutoffs vary by course.

Limitations

  • It uses a standard 4.0-scale conversion that schools may vary.
  • Weights for the average should not add up to more than 100%.
  • The final mode assumes the rest of your grade is already fixed.
  • Each item needs a valid grade and weight to count.

Frequently Asked Questions

How is the weighted average calculated?
Each grade is multiplied by its weight, those products are added together, and the total is divided by the sum of the weights.
How does the final grade mode work?
It uses your current grade, your target, and the final's weight to solve for the minimum score the final must earn to reach that target.
Can I mix letter and percentage grades?
Yes. When grades are mixed, the tool converts them to a common 4.0 scale before averaging.
What if the result says it isn't possible?
It means even a perfect final score would not reach your target, given how much the final is worth.
