Calculator inputs
Use the fields below to estimate the final exam score you need, your projected course grade, and several weighted grade scenarios.
Formula used
Current weighted contribution = Current average × (Completed coursework weight ÷ 100)
Required final exam score = (Target overall grade − Extra credit − Current weighted contribution) ÷ (Final exam weight ÷ 100)
Projected overall grade = Current weighted contribution + Expected exam score × (Final exam weight ÷ 100) + Extra credit
Letter grade = Determined from the custom A, B, C, and D cutoffs entered in the form.
How to use this calculator
- Enter your current average before the final exam.
- Enter the percentage weight already completed in the course.
- Enter the final exam weight so both weights total 100.
- Set your desired course grade and your expected exam score.
- Add extra credit, a pass mark, and custom grade cutoffs if needed.
- Choose a scenario range to compare many final exam outcomes.
- Submit the form to see required scores, projections, table results, and the Plotly graph.
- Use the CSV and PDF buttons to export the result area.

FAQs
1. What does this calculator estimate?
It estimates the final exam score needed for a target course grade, your projected overall grade, and multiple score scenarios based on weighted grading inputs.
2. Why must the weights total 100?
The calculator assumes your completed coursework and final exam together make up the full course grade. If they do not total 100, the weighted result becomes inaccurate.
3. What if the required final score is above 100?
That means the target grade is currently unreachable under the entered assumptions. You may need extra credit, a lower target, or a different grading policy.
4. What if the required final score is negative?
A negative requirement means you already secured the target with your existing coursework performance. Even a zero on the final would still keep you above that target.
5. Can I use custom letter grade cutoffs?
Yes. Enter your own A, B, C, and D thresholds. The calculator then labels projected grades and scenario results using your grading scheme.
6. What does the scenario table show?
It shows how your final course grade changes across a selected range of final exam scores. This helps you compare outcomes quickly and set realistic goals.
7. What is extra credit used for?
Extra credit adds points directly to the projected overall grade and required-score calculations. Use it only if your course policy awards added grade points.
8. What do the CSV and PDF options export?
The CSV export downloads the scenario table. The PDF export captures the visible result area, including summary cards, graph, and scenario table.
