College grade calculator formulas
Weighted course grade formula
Current weighted grade = Σ(grade × weight) ÷ Σ(weights)
Convert percentage weights consistently. If the completed parts of a class total 60% of the course, the calculator normalises those completed weights to show your current average while also showing the remaining 40%.
Points-based college grade formula
Course percentage = Total points earned ÷ Total points possible × 100
Use this method when assignments are added together by points instead of category weights. Extra-credit points can make the percentage exceed 100% if your course allows it.
