Weighted Grade Calculator
Most courses don't average scores equally — they weight categories. Enter each category's grade and its share of the course to get your true current standing.
Weights that don't total 100% are normalized automatically.
How weighted grades work
Each category grade is multiplied by its weight, the results are summed, and the total is divided by the combined weight. If homework (20%) sits at 95, the midterm (40%) at 78 and the final (40%) is still ahead, your current grade is (95×20 + 78×40) ÷ 60 = 83.7% — not the 86.5 a plain average would claim.
Worth knowing
Confirm the scale in your syllabus
The 90/80/70/60 letter cutoffs used here are the most common US scale, but plenty of courses curve, use plus/minus bands differently, or set an A at 94. The syllabus — not any calculator — is the contract that counts.
The registrar's number wins
Online gradebooks lag, professors enter marks late, and rounding policies differ by course. Any calculator — including this one — is a planning tool; the transcript is the record.
Percent and points are different animals
In a points-based course (600 points total), losing 12 points early costs the same as losing 12 late. In a weighted course, identical scores can move your grade differently depending on the category. Know which system you're in before doing mental math.
Common questions
Can I still pass if I fail the final?
Often, yes — it depends on your current grade and the final's weight. With an 80 going in and a final worth 20%, even a 40 on the final leaves you at 72. Run your exact numbers in the calculator; 'failing the final means failing the class' is only true when the final is very heavily weighted or your cushion is thin.
Do these calculators store my grades?
No. Everything is computed in your browser the moment you press Calculate — nothing is uploaded, saved or seen by anyone else. Refresh the page and it's gone.
Is a 90 an A or an A-?
In plus/minus systems, 90–92 is typically an A- and 93+ is an A, which affects GPA (3.7 vs 4.0). In straight-letter systems, everything from 90 up is simply an A. This calculator shows the plus/minus convention because it's the most common — your syllabus decides which applies to you.
