How to Use the Final Grade Calculator

  1. Enter your current course grade
    Type the average you have right now (as a percentage) in the “Current Grade” box. Example: if you’re sitting at 82 %, enter 82.
  2. Add the grade you want for the course
    In “Desired Grade,” enter the overall percentage you hope to finish with. For instance, to end with a B (≥ 85 %), type 85.
  3. Specify the final exam weight
    Look at your syllabus. If it says “Final Exam = 40 % of final grade,” type 40 in the “Final Exam Weight” field. Use whole-number percents (no decimals needed).
  4. Click Calculate
    The calculator instantly tells you the minimum percentage you must score on the final exam to hit your desired course grade.
  5. Review the result
    You’ll see a statement like "Final Exam Grade Needed 78.6 %". If the number is above 100 %, it means the target grade is not attainable under the current weighting.
  6. Hit Reset to run another scenario
    Planning contingencies? Click “Reset,” change any value, and recalculate as many times as you need.

Pro tip: If you still have other assignments left, combine their weights with the final exam weight and enter the total. Example: a project (10 %) + final (25 %) = enter 35 %.

Frequently Asked Questions

1. How does the Final Grade Calculator work?

We use the standard weighted-average formula:
Required Final Score = (Desired Course Grade − (1 − Final Weight) × Current Grade) ÷ Final Weight
All inputs are percentages, and the final weight is entered as a whole-number percent (e.g., 40 for a 40 % final).

2. What exactly is “Final Exam Weight”?

It’s how much the final counts toward your overall course grade. If your syllabus says “The final exam is worth 35 % of your semester grade,” type 35 in that box.

3. My course uses points, not percentages. Can I still use this?

Yes. Convert points to percentages first (points earned ÷ points possible × 100) and then plug those percentages into the calculator.

4. Does the calculator include extra-credit or bonus points?

Not automatically. If extra credit is allowed on the final, you can raise the “Desired Grade” or lower the “Final Exam Weight” manually to simulate its effect.

5. What if I have multiple remaining assessments, not just a final?

Combine all remaining assessments into a single “final” weight. For example, if a project (10 %) and final exam (25 %) are left, use 35 % as your “Final Exam Weight.”

6. Does the tool round up my required score?

The result is shown to two decimal places. Whether your instructor rounds grades is up to their policy, so aim for at least the displayed value to be safe.

7. Can I see what letter grade that percentage equals?

The Final Grade Calculator outputs a percentage only. Consult your course’s grading scale to convert the percentage to a letter grade.

8. Do you store or share my grades?

No. All calculations happen in your browser; nothing is saved or transmitted.

9. Can I use the calculator on my phone?

Absolutely. The page is mobile-friendly and works on iOS, Android, and any modern browser.

10. What if the required final exam score is over 100 %?

If the calculator returns a number above 100, it means reaching your desired course grade is mathematically impossible given the current inputs. You may need to adjust expectations or seek extra credit if available.
