How to Calculate Your Grade

Understanding how your grades are calculated gives you the power to plan your study time effectively. This calculator offers two essential tools: one that tells you what score you need on your final exam to achieve a target grade, and another that calculates your weighted average from multiple assignments.

The final grade formula is: Required Final = (Target − Current × (1 − Final Weight)) ÷ Final Weight. For example, if you have an 85% and your final is worth 30%, and you want a 90%: (90 − 85 × 0.70) / 0.30 = (90 − 59.5) / 0.30 = 101.67%. This tells you immediately if your goal is achievable or if you need to adjust your expectations.

The weighted average calculator multiplies each assignment score by its weight, sums the products, and divides by total weight. This is how most courses calculate final grades when different categories (homework, quizzes, exams, projects) have different weights. For instance, if homework worth 20% of your grade averages 95%, and exams worth 80% average 82%, your weighted average is (95 × 20 + 82 × 80) / 100 = 84.6%. Use this to track your progress throughout the semester and identify which categories matter most.
