How this grade percentage calculator works
The calculator divides points earned by total points, then multiplies by 100. Total points must be greater than 0, and blank fields are not treated as zero.
Extra credit and points over total
By default, points earned cannot exceed total points. If your class uses extra credit, enable the extra-credit option so percentages above 100% are allowed and labelled clearly.
What this tool does not include
This tool does not calculate weighted categories, curves, letter grades or school-specific pass marks. Grading systems vary by school, so use the rules from your assignment or class.
