Final grade calculator
Enter your current grade before the final, the final's weight, and your target. The page shows the score you need, the best grade still reachable, and the floor if the final scores zero. A target table covers every letter at once. Grades stay in this browser and in the share link fragment only.
What do I need on the final?
Use the gradebook number while the final is still ungraded. An ungraded final category does not pull that running grade down.
Category weights
Optional. Build a current grade from weighted categories, then push it into the field above when the final is not already in the table.

A current 85, a 30 percent final, a 90 target
Enter 85, 30, and 90. The required score is 101.67 percent, so a 90 overall is unreachable if the final cannot exceed 100. The best grade still reachable is 89.5, which is a perfect final on the remaining 30 percent. Skip the exam and the floor is 59.5, the current grade times the 70 percent already earned. That trio is the reason the page exists: a required score above 100 is not an instruction, and printing 112 without the ceiling would send someone into an exam they cannot use.
The number after an impossible target
Every serious final-grade calculator uses the same algebra. The gap is what happens when the required score comes back above 100. This page always shows the ceiling and the floor beside the required score, and when the target is unreachable it states the best grade still achievable instead of printing 112 as an instruction.
Formulas
With c as the current grade excluding the final, w as the final
weight as a fraction, and t as the target:
required = (t - c * (1 - w)) / wmaxAchievable = c * (1 - w) + maxFinal * wguaranteedMin = c * (1 - w)
Required scores round up to two decimals. Ceilings and floors round down, after a ten-decimal snap so floating-point noise cannot understate a promise. Weights that do not sum to 100 in the category calculator are normalized by dividing by their sum.
Questions
Does current grade include the final?
No. Enter the grade before the final. While the final sits at zero over zero, a gradebook's running average is already the average of what has been graded.
What if the final is worth 0% or 100%?
At 0% the course grade cannot change and the page says so. At 100% the required score equals the target and the current-grade field is ignored.
Are my grades uploaded?
No. The calculator runs in this tab. A share link keeps the numbers after the hash mark, which is not sent with the page request.
