Choose a Gradebook Calculation Method

Teachers can choose how their gradebooks calculate cumulative grades based on points, weights, and assignment factors.

Use this topic to:

  • Understand Total Points, Total Points with Weight, and Percentages calculation methods.

  • Compare how each method calculates cumulative grades.

  • See step-by-step calculation examples.

Note: For information about grade column formulas, see Grade formulas in Grades management. For GPA calculations, see Create Grade Calculations & Rank.

To access gradebook calculation settings:

  1. In Faculty, select Classes.

  2. Choose a class.

  3. Select Launch gradebook.

  4. Select More, then Settings.

  5. Select the Grade calculation tab.

Calculation Method Overview

Total Points:

  • Calculates grades using total points earned divided by total points attempted.

  • Assignment types (such as Homework or Exams) do not impact the calculation.

  • Best for courses where all assignments contribute directly based on point value.

Total Points with Weight:

  • Calculates grades within each assignment type using points earned and maximum points.

  • Applies weights to assignment types (for example, Homework 30%, Exams 40%).

  • Assignments with higher point values have greater impact within their category.

  • Use when assignment types are weighted, but assignments within an assignment type have varying max points.

Percentages:

  • Converts each assignment to a percentage, then averages them within each assignment type.

  • Applies weights to assignment types.

  • Each assignment contributes equally within its category, regardless of point value.

    Tip: Extra credit assignment can have a big impact. See extra credit example calculations.

  • Use when assignment types are weighted and assignments within a type have the same max points.

Gradebook Calculation Formulas

Total Points Formula

(Sum (Points earned × Assignment factor) / Sum (Maximum points × Assignment factor)) × 100 = Cumulative grade

Total Points with Weight Formula

First: For each assignment type: Sum (Points earned × Assignment factor) / Sum (Maximum points × Assignment factor) = Assignment type grade

Next: (Sum (Assignment type grade × Weight) / Sum (Weight)) × 100 = Cumulative grade

Percentages Formula

First: For each assignment type: Sum ((Points earned / Maximum points) × Assignment factor) / Sum (Assignment factor) = Assignment type grade

Next: (Sum (Assignment type grade × Weight) / Sum (Weight))× 100 = Cumulative grade

Assignment Factors

Factors weight individual assignments rather than an entire assignment type. A factor determines how many times an assignment is counted in calculations.

For example, if an assignment has a factor of a factor of 2, the impact of the assignment on the calculation is doubled. A factor of .5 reduces the impact of the assignment by half. For more information on how factors affect calculations, see Assignment Factor.

The maximum points are the same for all assignments within their assignment types.

  1. Calculate total points earned.

    1. Multiply each score by the assignment factor, then add the results.

    (9×1) + (8×1) + (18×1) + (14×1) + (90×1) + (60×1) = 199

  2. Calculate total maximum points.

    1. Multiply each maximum score by the assignment factor, then add the results.

    (10×1) + (10×1) + (20×1) + (20×1) + (100×1) + (100×1) = 260

  3. Divide total points earned by total max points.

    199 / 260 = 0.7654
