The Formula Behind It

Grade = Σ(Score × Weight) / Σ(Weight)

How It Works

  1. Enter score (0–100) and weight for each assignment category.
  2. Use up to four categories (homework, midterm, final, etc.).
  3. View weighted course grade and letter equivalent.

About Grade Calculator

The Grade Calculator computes your weighted course grade from assignment categories with different weights. Essential for tracking progress mid-semester and calculating what you need on the final exam.

Weighted Grade Formula

Grade = (Score₁ × Weight₁ + Score₂ × Weight₂ + …) / Total Weight. Weights should sum to 100% for a complete course breakdown.

Frequently Asked Questions

How is a weighted grade calculated?

Multiply each assignment score by its weight percentage, sum them, and divide by total weight.

What if weights don't add to 100%?

The calculator normalizes by total weight entered — weights should ideally sum to 100%.

Can I use letter grades?

Enter percentage scores (0–100) for each category. Convert letter grades to percentages first.

How do I find what I need on the final?

Enter current assignments with weights, then model a final exam weight to see required scores.

Is this for college or high school?

Both. Any course using weighted categories works with this formula.

What is a passing grade?

Varies by institution — typically 60% or D. Check your syllabus for cutoffs.
