Why it Matters

Before a final exam, the most useful number is the score you actually need to hit your goal — anything less is guesswork. This calculator works the weighted-grade formula backwards so you can set a realistic study target, know when you've already secured the grade, and recognise early if a goal is out of reach. That clarity turns exam season from anxiety into a plan.

What this tool does

The Grade Calculator tells you the score you need on your final exam to finish a course with the overall grade you’re aiming for. Enter your current grade, how the course is weighted, and your target — the required score and a what-if table appear instantly.

How it works

It runs the weighted-grade formula in reverse: required final = (target − current × currentWeight) / finalWeight, with weights expressed as fractions. The what-if table then plays the formula forward for a range of final scores. The logic is a pure function — identical inputs always give identical results.

Informational only

Courses weight components differently and some apply rounding or drop-lowest rules. Use this as a planning guide and confirm the exact weighting from your syllabus or instructor.

Frequently Asked Questions

How do I calculate the grade I need on my final?
Subtract the points your completed work contributes (current grade × current weight) from your target, then divide by the final's weight as a fraction. For example, with 82% over 70% completed and a 30% final, reaching 75% needs (75 − 82×0.7) ÷ 0.3 ≈ 58.7% on the final. The tool does this for you.
What do 'current weightage' and 'final weightage' mean?
Current weightage is the share of your overall grade that's already been graded (homework, quizzes, midterms). Final weightage is the percentage the final exam is worth. They should normally add up to 100% — the tool warns you if they don't.
What if the required score is over 100%?
It means the target is no longer reachable with the final alone. The calculator flags this clearly so you can aim for the best score possible and explore options like extra credit with your instructor.
Can my target already be locked in?
Yes. If your completed work alone already meets the target, the tool tells you the grade is secured even if you scored zero on the final — useful for knowing where to focus your energy.
Is my data sent anywhere?
No. The calculation runs entirely in your browser. Nothing you enter is uploaded, logged, or stored — refreshing the page clears everything.
