How this is calculated
Divide the points earned by the points possible and multiply by 100: 30 ÷ 50 × 100 = 60%. On the common 10-point-band scale that lands in the D- range — you'd have needed 45/50 to reach the A band.
Common questions
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.
What's the difference between weighted and unweighted averages?
An unweighted average treats every score equally: add them up, divide by the count. A weighted average multiplies each category by its share of the grade first — homework 20%, midterms 40%, final 40% — which is how most courses actually work. If your syllabus lists category percentages, you need the weighted version.
