How to Use the Grade Calculator

Add your assignments with their weight percentages and scores. Weights don't need to sum to 100 — they're normalised automatically.

Formula

Weighted Average = Σ(Score × Weight) ÷ Σ(Weights)

Frequently Asked Questions

What if weights don't add to 100?

The calculator normalises weights automatically, so you can enter 20/35/45 or 2/3.5/4.5 — the result is the same.
