About Canvas Grade Calc — What Do I Need?
Moved to " Canvas Power Tools " !
Instantly know your grade and what you need.
Canvas Grade Calculator shows you exactly where you stand in every Canvas course — even when your professor has disabled grade totals.
FEATURES
▸ Your Real Grade, Always Visible
See your current percentage and letter grade calculated in real time from your Canvas grades page.
Works with both weighted and unweighted (points-based) courses.
▸ "What Do I Need?" Calculator
Pick your target grade (A through D, with plus/minus options) and instantly see what score you need to
average on your remaining assignments. No guessing, no spreadsheets.
▸ What-If Simulator
Drag sliders to simulate scores on upcoming assignments and watch your grade change in real time. See
exactly how each assignment affects your final grade.
▸ Assignment Group Breakdown

and weight percentages.
▸ Works When Totals Are Disabled
Many professors disable Canvas's built-in grade totals. This extension calculates your grade anyway.
