Grade Calculator
Work out your weighted course grade from assignments and exams, and the score you need on the final exam to reach the grade you want.
Weighted average of entered work
Scores and targets use a 0–100 percentage scale. Final mode assumes the current grade describes all non-final work. The final’s weight must be greater than zero. School-specific rounding, extra credit and minimum-pass rules are excluded.

How this calculator works
Weighted course mode averages the work entered, normalising by its combined weight. Final exam mode solves the remaining weighted equation for a target overall grade. A required score above 100 is reported directly rather than hidden; a negative score means the target is already reached even at zero on the final.
Formula
Weighted grade = Σ(score × weight) / Σ weights. Final needed = (target − current × (1 − final fraction)) / final fraction.
Assumptions & limitations
Scores and targets use a 0–100 percentage scale. Final mode assumes the current grade describes all non-final work. The final’s weight must be greater than zero. School-specific rounding, extra credit and minimum-pass rules are excluded.
Worked example
Scores of 80 and 90 with weights 40 and 60 give 86%. A current 80 with a final worth 20% requires 105% on the final to reach 85%, so the target exceeds a normal 100-point maximum.

Common questions
Must weights add up to 100?
Not in the graded-work mode: the entered weights are normalised. This can show the average so far without treating missing assignments as zero.
Why is the required final score above 100?
The entered target cannot be reached on a standard 0–100 final under those weights. Check the inputs or your school’s extra-credit policy.
Is this a GPA calculator?
No. This tool combines percentage scores. GPA translates letters to grade points and weights those points by course credits.
