How to Calculate GPA in Ontario

Reviewed by Calculator Editorial Team

Calculating your Grade Point Average (GPA) in Ontario is essential for tracking academic progress, applying to universities, and understanding your performance. This guide explains the Ontario GPA calculation method, provides a step-by-step calculation guide, and includes a GPA calculator to simplify the process.

How GPA is Calculated in Ontario

The Ontario GPA system is based on a 4.0 scale, where each course is assigned a grade point value. The GPA is calculated by multiplying each course's grade points by its credit hours, summing these values, and dividing by the total credit hours attempted.

GPA Formula

GPA = (Σ (Grade Points × Credit Hours)) / Σ Credit Hours

This method ensures that both the quality of your grades and the workload of your courses are considered in your overall academic performance assessment.

Ontario GPA Scale

The Ontario GPA scale assigns specific grade point values to letter grades, as shown in the table below:

Letter Grade Grade Point
A+ 4.0
A 4.0
A- 3.7
B+ 3.3
B 3.0
B- 2.7
C+ 2.3
C 2.0
C- 1.7
D+ 1.3
D 1.0
F 0.0

Note that some institutions may use slightly different grade point values, but the 4.0 scale is the most common in Ontario.

Step-by-Step Guide to Calculating GPA

  1. Gather Your Course Information

    Collect the letter grades and credit hours for each course you've taken. Credit hours typically range from 0.5 to 1.0 per course, depending on the course level.

  2. Convert Letter Grades to Grade Points

    Use the Ontario GPA scale to convert each letter grade to its corresponding grade point value.

  3. Multiply Grade Points by Credit Hours

    For each course, multiply the grade point by the credit hours to get the quality points.

  4. Sum the Quality Points and Credit Hours

    Add up all the quality points and all the credit hours to get the total quality points and total credit hours.

  5. Calculate the GPA

    Divide the total quality points by the total credit hours to get your GPA.

Important Notes

  • Only include courses that count toward your GPA (typically those with letter grades).
  • Some institutions may have different grading policies, so check with your school if you're unsure.
  • GPA calculations can vary slightly between institutions, so always use the specific guidelines provided by your school.

Example Calculation

Let's calculate the GPA for a student who has taken three courses:

Course Credit Hours Letter Grade Grade Point Quality Points
English 10 1.0 A 4.0 4.0
Mathematics 10C 1.0 B+ 3.3 3.3
Science 10 1.0 A- 3.7 3.7
Total Quality Points 11.0
Total Credit Hours 3.0

GPA = Total Quality Points / Total Credit Hours = 11.0 / 3.0 = 3.67

This student's GPA is 3.67, which is a strong academic performance.
