Grade Calculator
Add each assignment, test, or category with its score and weight to calculate your overall weighted grade percentage.
About the Grade Calculator
Course grades are usually built from several weighted components — a midterm worth 30%, homework worth 20%, a final worth 50%, and so on — and figuring out your current standing partway through a course means doing a weighted average by hand, which is exactly the kind of calculation that's easy to get wrong under time pressure before an exam.
How it works
Each item's score is multiplied by its weight, those results are summed, and the total is divided by the sum of the weights actually entered — not assumed to be 100. That means you can use this partway through a term, entering only the components graded so far, and get an accurate "current grade" reading rather than needing every component finalized first.
Typical use
Checking whether you're on track for a target final grade, working out what you'd need on a remaining exam to reach a specific overall grade (by trial-and-error entry), or simply converting a syllabus's weighting scheme into a running total as the term progresses.
Frequently Asked Questions
What if my weights don't add up to 100%?
The calculator still works — it divides the weighted sum by whatever total weight you've entered, so the result is correct even if your weights sum to something other than 100 (though for a typical course, they should add up to 100%).
What does the letter grade mean?
A rough general guide (90+=A, 80+=B, 70+=C, 60+=D, below 60=F) — always check your specific institution's or instructor's actual grading scale, since these vary.
