## Quick Answer

Average a list of percentage grades. Simple mode takes the plain mean; weighted mode lets each grade carry its own weight. The result is the average percent and its letter grade on the calculator's default scale.

## Definition

A grade average calculator reduces a list of percentage grades to a single number. Simple mode adds the grades and divides by how many there are, treating each equally. Weighted mode multiplies each grade by a weight, sums those products, and divides by the total weight, so a heavily weighted exam moves the average more than a quiz. Weights are relative and need not total 100. Students and teachers use it to track performance across several assessments at once.

## How to Use

1. **Choose simple or weighted average** — Pick simple average to treat every grade equally, or weighted average to give some grades more influence.
2. **Input your grades** — Enter each grade as a percentage, one per row. Add rows as you need them.
3. **Add weights if you chose weighted** — Type a weight beside each grade. Weights are relative, so 2 and 1 works as well as 20 and 10.
4. **Read your average** — View the average percent and the matching letter grade on the default scale.
