Formula: Needed = (Desired − Current × (1 − Weight)) / Weight
📐 Formula
Needed = (Desired − Current × (1 − Weight%)) / Weight%- Enter your current grade in the class as a percentage.
- Enter the overall grade you want to finish with.
- Enter the final exam’s weight as a percentage of your total grade (treated as a fraction of 1 in the computation).
- The calculator returns the exam score required to hit your target.
🎯 Final Grade Calculator
Exam week is stressful enough without guessing what score you actually need. This tool removes the guesswork: it takes your current grade, your desired final grade, and how much the final exam counts toward your total, then tells you the exact score required on the exam.
A worked example shows how to interpret the result. Suppose you want to finish with 90% overall, you currently hold an 85%, and the final exam is worth 30% of your grade. The formula gives (90 − 85 × 0.70) / 0.30 ≈ 101.7% — a score above 100%, meaning that target is mathematically unattainable. When that happens, adjust your desired grade downward until the needed score is realistic, and you’ll know precisely what to aim for on exam day.

What if the needed score exceeds 100%?
The target is mathematically impossible; lower the desired grade and recalculate to find an achievable goal.
