MihsabaHow to use
This calculator is for course percentages, not GPA. Enter score-weight pairs for a weighted grade, or work backward to find the final-exam score needed for a target.
- Choose weighted grade or needed-on-final mode.
- For weighted mode, enter one score, weight pair per line.
- For final mode, enter current grade, final weight and target.
- Review the result and reachability status.
How it is calculated
G=Σ(score×weight)÷Σweight; needed=(target−current×(1−w))÷w
Example
Scores 80 at weight 40 and 90 at weight 60 produce 86%. If current grade is 85, the final is 20% and target is 88, you need 100% on the final.
Important notes
Weights do not need to sum to 100 because weighted mode normalizes by their total. Letter-grade cutoffs vary by institution, so no universal letter scale is assumed.
Frequently asked questions
Is this the GPA calculator?
No. GPA is a separate tool based on grade points and credits.
What if weights do not total 100?
The result is normalized by total entered weight.
What does needed over 100% mean?
The target is not reachable from the final alone without extra credit.
Is this calculator free?
Yes. It is free to use and requires no account.
