Final Grade Calculator

Find the final exam or final project score you need to finish a course at your target grade, and test a what-if final score on the same scale.

%
Examples

Current 82, final weight 30%, target 85 on a 0-100 scale.

Required final score
92 / 100
Reachability
Reachable

You need 92 on the final to finish at 85.

Straight weighted grading only. This may not match curved classes, dropped assignments, extra credit, minimum-pass components, or institution-specific rounding rules.

How It Works

Formula

G=C⋅(1−w)+F⋅wG = C \cdot (1 - w) + F \cdot w

Frequired=T−C⋅(1−w)wF_{\text{required}} = \frac{T - C \cdot (1 - w)}{w}

Variables

GG

Projected overall course grade

CC

Current grade before the final assessment

FF

Final exam or final project score

TT

Target overall course grade

ww

Final assessment weight as a decimal

Enter your current grade, the final assessment weight, and the overall grade you want. All grade values use the same numeric scale, with 0-100 as the default. The calculator solves the weighted-average formula for the final score required to reach the target.

If you also enter an assumed final score, it runs the forward calculation on the same scale and shows the projected overall course grade. Targets that are already secured or impossible on the chosen scale are labeled plainly instead of showing misleading negative or above-scale answers as if they were normal outcomes.

Frequently Asked Questions

01How is the required final score calculated?
The calculator treats the course as a straight weighted average. It solves the target-grade equation for the final score: required final = (target − current × (1 − w)) / w, where w is the final weight as a decimal.
02What does "already secured" mean?
It means your current weighted coursework is already enough to reach the target overall grade. The raw formula would give a negative required final score, so this calculator reports the honest state instead.
03What does "impossible on this scale" mean?
It means the target would require a final score above the maximum of your chosen scale. The calculator labels that plainly and shows the overall grade you would finish with if the final score were perfect on that scale.
04When can the real course grade differ from this result?
This models straight weighted grading only. Curved classes, dropped assignments, extra credit, minimum-pass components, and institution-specific rounding rules can all change the real outcome.
