How Canvas Calculates Your Grade
Canvas (by Instructure) calculates grades using a weighted or points-based system depending on how your instructor sets up the course. In a points-based course, your grade is simply the total points earned divided by the total points possible. In a weighted course, assignment groups (e.g., Homework 30%, Exams 40%, Participation 30%) are each calculated separately, then blended by their weights.
This calculator uses the points-based method (Mode 1), which matches the most common Canvas setup. If your course uses assignment group weights, enter assignments from each group separately and note the proportions.
What Do I Need on My Final? — Formula
needed = (desired_grade − current_grade × (1 − exam_weight/100)) / (exam_weight/100)
Example: current = 82%, desired = 90%, final weight = 20%
needed = (90 − 82 × 0.80) / 0.20 = (90 − 65.6) / 0.20 = 24.4 / 0.20 = 122%
