Use this calculator when you know the next score and your class drops the lowest score. It projects the average after the next score is added and the drop-lowest policy is reapplied.
Enter current equal-weight percentage scores. Use 84 for 84%, separated by commas, spaces, or new lines.
Enter the known or expected next equal-weight score. Use 91 for 91%.
Use the number of lowest equal-weight scores your teacher drops from the final list.
Optional comparison target for the projected dropped-lowest average.

What this dropped-lowest projection solves
This calculator projects a new average after one known next score is added to an equal-weight score list and the lowest score or scores are dropped. It is the forward version of a dropped-lowest target calculation.
Formula
How to use it
- Enter the current equal-weight scores in the same grade group.
- Enter the known or expected next score.
- Enter how many lowest scores your teacher drops.
- Enter a target average if you want a comparison.
- Check which score is dropped after the next score is added.
How to read the answer
The projected average is the average after the next score is added and the lowest score or scores are removed. The no-drop projection shows what the average would be if every score counted, which helps explain how much the drop policy changes the result.
When to use another grade tool
Use the score needed with dropped lowest calculator when you know the target but not the next score. Use the grade drop calculator when all scores are already known. Use the weighted grade calculator when categories have separate weights.
Common mistakes and edge cases
- Do not use this if assignments have different point values unless your teacher averages their percentages equally.
- The next score can be the one that gets dropped if it is the lowest score in the final list.
- A score below the current dropped-lowest average can still be useful if it changes which score is dropped.
- Scores above 100% usually mean extra credit or a curved grading policy.
Worked examples
Project the next score with one dropped score
Six current scores plus a 91% next score project to an 88% average after dropping the lowest score.
Projected average
88%
Next score gets dropped
A very low next score may become the dropped score, leaving the current dropped-lowest average unchanged.
Projected average
93%
Projection misses target
A known next score can still miss the target after the drop policy is applied.
Projected average
78%
Invalid drop count
The number of dropped scores must be smaller than the current score list.

Frequently asked questions
How do I calculate my average after the next score if the lowest score is dropped?+
Add the next score to your current scores, sort the full list, drop the lowest score or scores, then average the remaining scores.
Is this different from the score needed with dropped lowest calculator?+
Yes. This calculator projects the average from a known next score. The score needed with dropped lowest calculator works backward from a target to the next score required.
Can the next score be dropped?+
Yes. If the next score is lower than every current score and the policy drops the lowest score, the next score may be removed from the final average.
Why show a no-drop projection?+
The no-drop projection shows what the average would be if every score counted, making it easier to see how much the drop-lowest policy changes the result.
Can I use this for weighted grades?+
Only if these scores are averaged equally inside one category. Use the weighted grade calculator when categories have separate course weights.
