# Final Grade Needed Calculator

Calculate exactly what grade you need on your final exam to get your desired course grade. Enter your current grade, target grade, and final exam weight.

## What this calculates

Stressing about finals? Enter your current course grade, your target overall grade, and how much the final exam is worth, and this calculator tells you exactly what score you need. It also shows the minimum score needed just to pass the course.

## Inputs

- **Current Grade** (%) — min 0, max 100 — Your grade before the final exam
- **Desired Final Grade** (%) — min 0, max 100 — The overall grade you want to achieve
- **Final Exam Weight** (%) — min 1, max 100 — What percentage of your grade the final is worth

## Outputs

- **Grade Needed on Final**
- **Feasibility** — formatted as text — Whether the desired grade is achievable
- **Grade Needed to Pass (60%)**

## Details

The formula is:

Needed Grade = (Desired Grade x 100 - Current Grade x (100 - Final Weight)) / Final Weight

For example, if you have an 82% in a class and want a 90%, with a final worth 30%:

Needed = (90 x 100 - 82 x 70) / 30 = (9000 - 5740) / 30 = 108.7%

That would be nearly impossible without extra credit, so you might need to adjust your target grade.

## Frequently Asked Questions

**Q: What if the calculator says I need over 100%?**

A: If the required grade exceeds 100%, you cannot achieve your desired grade through the final exam alone without extra credit. Consider adjusting your target grade to something more realistic, or ask your professor about extra credit opportunities.

**Q: How do I find my current grade?**

A: Check your school's online grade portal (Canvas, Blackboard, etc.) for your current weighted average. If that's not available, calculate it by weighting each assignment score by its category weight.

**Q: Does this account for all grading categories?**

A: This calculator assumes your current grade reflects all work completed so far (before the final), and the final exam makes up the remaining weight. If the final replaces your lowest exam score, the calculation would be different.

**Q: What is a typical final exam weight?**

A: Final exams typically account for 20-40% of the total course grade. Some courses weight the final as high as 50%, while others may not have a traditional final exam at all.
