Your course grade is your current grade weighted by everything except the final, plus the final weighted by its share. Solve for the final to see what you need.

Also called: Final grade calculator, What do I need on my final calculator.

## Inputs
- Current grade (before the final) (unit %; default 82)
- Final exam weight (unit %; default 30)
- Target course grade (unit %; default 85)

## Results
- Score needed on the final
- Course grade with 100% on the final
- Course grade with 0% on the final
- Verdict

## Formula

```
Needed = (T − C × (1 − w)) ÷ w
```

Where:
- T: target course grade (%)
- C: current grade on everything except the final (%)
- w: final exam weight as a fraction

## Worked example
1. The non-final part contributes 82 × 0.7 = 57.4 points.
2. Needed = (85 − 57.4) ÷ 0.3 = 27.6 ÷ 0.3 = 92%.
3. With 100% on the final the course grade would be 57.4 + 30 = 87.4%.

**Result:** With 82% so far and a final worth 30%, you need 92% on the final to finish with 85%.

## What the result means

A required score above 100% means the target is out of reach unless there is extra credit; a score at or below 0% means the target is already secured.

## Assumptions and limits
- Your current grade already reflects the weights of every non-final item.
- Courses with a pass-the-final rule, curves or dropped lowest scores need their own adjustments.

## Questions

### What if my teacher’s weights add up to more than the final plus coursework?

### Can I use this with points instead of percentages?

Convert your points to a percentage first (points earned ÷ points possible × 100).
