Weighted Grade Calculator: The Complete Guide

Calculate a grade where components count differently. Enter each item's score and weight, one per line, to get your weighted average — ideal for courses split into homework, quizzes, tests, and a final.

Who the Weighted Grade Calculator is for

Students computing a course grade where different components carry different weights.

How to use the Weighted Grade Calculator

  1. Type your values into the fields above — pick your currency or units where the calculator offers them.
  2. Results update automatically as you type; there's no submit button and nothing is sent to a server.
  3. Adjust any input to compare scenarios, then copy the result with a single click.

How it works

Weighted grade = Σ(score × weight) ÷ Σ(weight). Weights don't need to add to 100 — they're normalised automatically.

Features

  • Weighted average
  • Weights auto-normalised
  • Any number of items
  • Letter grade

Why weighting matters

Most courses don't weight everything equally — a final exam might count for 40% while homework counts for 10%. A weighted average multiplies each score by its weight, sums them, and divides by the total weight, so heavily-weighted components move your grade more. This calculator normalises the weights for you.

Frequently Asked Questions

Do my weights have to add up to 100?

No — the calculator normalises them. Whether you enter weights as 20/30/50 or 2/3/5, the weighted average is the same.

Can I mix percentages and points?

Use consistent scores (all percentages works best). The weights can be any numbers reflecting each component's importance.

Is this calculator free and private?

Yes. It's completely free with no signup, and every calculation runs locally in your browser, so your numbers never leave your device.
