About the Grade Calculator
This free Grade Calculator works out your weighted class grade and matching letter grade in seconds. Enter the score you got on each assignment, quiz, or test along with how much it's worth (its weight), and your overall percentage updates live. Empty rows are ignored, so you can use anywhere from two to six categories.
It uses the standard US grading scale (A, B, C, D, F), and shows whether your weights add up to 100% so your result stays accurate. Like every Pixveil tool, it runs 100% in your browser — nothing you type is uploaded, stored, or seen by anyone — and it is free forever, with no signup and no ads.
