A final grade calculator that answers the question every student asks before exam week: what do I need on my final to get the grade I want? Enter your current standing and the weight of the final exam, set a target overall grade, and the tool returns the exact score you need on the final — instantly, in your browser. It also produces a what-if table so you can see the required final score for every common target at once, from a comfortable C all the way up to an A+.
How it works
Your overall course grade is a weighted average. Everything you have already completed contributes a fixed number of points to a 100-point total, and the final exam contributes the rest. The tool first works out the points you have locked in: your current grade multiplied by the share of the course that is already finished. It then solves a single equation for the unknown final score:
required final = (target − locked-in points) ⁄ (final weight ⁄ 100)
If the final is worth 30% of your grade and you have banked 60 points from the other 70%, hitting an 85% overall needs a final of (85 − 60) ⁄ 0.30 ≈ 83%. The result panel spells this out, classifies it as secured, achievable, tough, or out of reach, and shows the full range your final grade can land in — from scoring zero on the final to scoring full marks.
The Weighted components mode goes further: instead of one current grade, you list each completed assessment with its own score and weight. The tool sums their weighted contributions, displays your current average and the matching letter grade, and warns you if the weights do not add up to 100%. Either way, the what-if table recomputes the required final score for nine standard targets so you can pick a realistic goal, and a one-click export saves a tidy plain-text plan.
Example
Suppose your current grade is 82% and the final exam is worth 30% of the course. That means 70% of the grade is already settled, locking in 82% × 70 = 57.4 points. To finish at 85% you need (85 − 57.4) ⁄ 0.30 ≈ 92% on the final — tough but possible. Drop the target to a B (83%) and the required final falls to about 85%. Aim for an A− (90%) and the table shows you would need over 108% — out of reach, so the tool flags it with a warning. Seeing the whole spread at once makes it easy to set a goal you can actually hit and plan your revision time around it.
