Grade Calculator
With an 85 going into a final worth 20% of your grade, you need a 60% on the final to finish with a B (80%). Enter your current grade, how much of the course is already done, your target, and the final's weight. The calculator tells you the exact score the final has to be.
Quick answer
Current coursework and final exam are weighted percentages of your total course grade.
What this tells you
- •Current coursework and final exam are weighted percentages of your total course grade.
- •If required score is above 100%, your target is not achievable with the current inputs.
- •If required score is below 0%, you already secured your target grade.
How to Use
- 1Enter your current grade percentage.
- 2Enter the percentage weight already completed.
- 3Enter your target overall course grade.
- 4Enter the final exam weight.
- 5Review the required final exam score and status.
How It Works
Formula
Required Final Score = (Target Grade - Current Grade x Current Weight) / Final WeightThe calculator solves the weighted average equation using percentages as weights that add up to 100.
Calculation note: values are processed in the order shown above, using the current input units.
Worked Examples
What grade do I need on my final to get a B with an 85?
With an 85 going in and a final worth 20% of the course, you only need a 60% on the final to finish with a B (80%). Your existing coursework already carries most of the weight.
Need an A from a strong B
You need to outperform your current average on the final because it still has enough weight to move the total.
What You Need on the Final to Get a B (80%)
Required final exam score to finish with an 80% overall, assuming the final is worth 25% of your course grade.
| Current grade | Score needed on final |
|---|---|
| 75% | 95% |
| 78% | 86% |
| 80% | 80% |
| 82% | 74% |
| 85% | 65% |
| 88% | 56% |
| 90% | 50% |
| 95% | 35% |
Formula: required = (80 - current x 0.75) / 0.25. If your final has a different weight, use the calculator above for an exact answer.
Common mistakes
- Using point totals instead of percentages
- Entering weights that do not add up to 100
- Confusing current grade with target grade
