Next Score Needed Calculator
Use this next score needed calculator when your teacher averages a list of equal-weight percentage scores and you want to know what the next score must be to reach a target average.
Enter the percentage scores that already count. Use 84 for 84%, separated by commas, spaces, or new lines.
Enter the average you want after one more equal-weight score is counted. Use 88 for 88%.
Use 100 for a normal full-credit score, or a higher value if extra credit is possible.

What this next score needed calculator solves
This calculator works backward from a target average. It treats the next quiz, test, homework, or assignment as one more equal-weight percentage score in the same list.
Formula
How to use it
- Enter the percentage scores currently counted in the same grade group.
- Enter the average you want after one more equal-weight score.
- Keep the maximum next score at 100 unless extra credit or a curved score is possible.
- Check whether the required next score is reachable under the maximum score.
- Use the related grade tools if your class uses points, weighted categories, a final exam weight, or a retake replacement policy.
How to read the answer
The next score needed is the percentage that must be added as the next equal-weight score for the new average to hit the target. If it is above the maximum next score, the target needs extra credit, more future scores, or a different class policy.
When to use another grade tool
Use the final grade calculator when the next score has a known final-exam weight, the test grade calculator for one score from points earned and missed, the weighted grade calculator for syllabus categories, and the retake score needed calculator when an old score is being replaced.
Common mistakes and edge cases
- Do not use this for a final exam unless the final counts the same as every other score in the list.
- Do not mix weighted categories unless your teacher averages all entered percentages equally.
- If the score needed is above 100%, compare it with your actual extra-credit or curve policy.
- If only one or two scores are entered, the next score can move the average sharply.
Worked examples
Reach an 88 average
Scores of 72, 84, 88, 91, and 95 need a 98% next equal-weight score to reach an 88% average.

Target already met
A current high score list can already have enough room to stay above a lower target.

Unreachable with a normal score
Low current scores may need more than 100% on the next equal-weight score.

Frequently asked questions
How do I calculate what score I need next?+
Add one to the current number of scores, multiply that count by the target average, then subtract the sum of your current scores. The result is the next score needed.
Is this the same as a final grade calculator?+
No. A final grade calculator uses a known final exam or project weight. This calculator assumes the next score counts exactly like each existing score in one equal-weight list.
What if the score needed is over 100%?+
Then the target is not reachable with a normal full-credit next score alone. It may require extra credit, a curve, more future scores, or a different teacher policy.
Can I use this for weighted categories?+
Only if the entered scores are averaged equally inside one category. Use the weighted grade calculator when homework, quizzes, tests, and projects have different category weights.
What if I already meet the target?+
The calculator shows 0% when the target would still be met even if the next equal-weight score were zero. That is a planning signal, not advice to skip work.
