Grade Calculator

A weighted grade accounts for the fact that different assessments (homework, midterms, finals) contribute differently to your overall score. Each grade is multiplied by its percentage weight, and the sum is divided by total weight to produce your true average.

How Weighted Grade Calculation Works

Each grade is multiplied by its weight, ensuring tests worth more of your grade have an appropriately larger impact on your final score.

Plan Your Study Time

Knowing your required final score lets you allocate study time wisely — spend less effort when you're already safe, and double down when every point counts.

Required Score Formula

Required = (Target - Current × (1 - FinalWeight%)) / FinalWeight%

This formula isolates the final exam score needed to hit your desired overall grade, given your current standing and the exam's weight in the course.

Calculation Examples

Typical Scenario

If your current grade is 85%, you want 90%, and the final is worth 20%, you need to score 110% — meaning boost your current grade before finals!

Playing It Safe

With a current grade of 92% and a target of 90% with a 30% final, you only need about 84% on the final.
