Grade Needed Calculator
The week-eight version of the final-grade question: enter everything already graded and the calculator works out what the rest of the course has to average for you to finish where you want — with the best and worst outcomes still on the table.

Common plus/minus convention; many schools use straight letters or different cut points.
You need 86.4% on everything left.
The remaining 50% of the course has to average that. On the US scale that is around B.
🔢 Show the math
- Work graded so far covers 50% of the course; 50% is still to come.
- Points already banked: 92% × 20% + 78% × 30% = 41.8 points of the 100 available.
- To finish at 85% you still need 43.2 points from the remaining 50%.
- 43.2 ÷ 50 × 100 = 86.4% on what is left.
Grading scales vary by institution — your school's own table and syllabus govern. Conversions shown here follow common published conventions.
🎓 Understand this tool
What it is
This works out what everything still ungraded has to average for you to finish a course at a particular grade — the mid-semester version of the final-exam question.
How it works
Each graded item contributes its score times its weight to a running total of points banked out of 100. Whatever weight is left over is the remaining block. Subtract the banked points from your target and divide by that remaining weight to get the average it must earn.
Getting the most from it
- Enter every item that has been graded, with the weight the syllabus gives it.
- Do not enter the ungraded work — the tool infers the remaining weight from what is left over, which avoids guessing at weights that have not been announced.
- Set the target to a grade you actually need, then try one or two others; the numbers change faster than most people expect.
- Check the best-possible-finish line before making plans around the target.
Reading your result
A result at or below 100 is achievable across the remaining work. Above 100 means the target is out of reach and the best-possible figure is what to plan around. A result at or below zero means the target is already secured whatever happens next.
What it can't tell you
It treats the remaining work as one block averaging a single figure, which is the right frame for planning but not a per-assignment target. It also cannot know about rounding, dropped scores, or extra credit still to be announced.
Frequently asked questions
How is this different from the final grade calculator?
The final grade calculator assumes one exam is all that is left. This one takes several graded items and treats everything still to come as a block, which is the shape of the question mid-semester when there are assignments, a project, and a final still ahead.
What if I do not know all the remaining weights?
You do not need them individually. Enter the work already graded and the calculator infers that the rest of the course is whatever weight is left over, then tells you what that block has to average. Splitting it up only matters when you want per-assignment targets.
What does it mean if the number is negative?
That you have already secured the target: even scoring zero on everything remaining leaves you at or above it. The calculator says so plainly rather than showing a negative percentage, and shows the floor you would land on in that case.
Can I plan several targets at once?
Change the target field and the answer updates immediately, so it takes seconds to see what an A, a B, and simply passing each require. Copying the link saves the current setup, which is useful when you want to send someone your exact numbers.
