GPA Calculator

How is your GPA calculated?

Your GPA are calculated using a method called Weighted Average. Not all your grade points carry the same importance, and that is where the concept of weightage comes into play. This grade calculator is a tool that will help you calculate your grades based on weighted averages. 

You can add your Courses and their weight and get your grade results. We support both letter grades and numerical grades. Please look at our table if you are unsure about our letter grades, and use the numerical grades.

To calculate your grades for individual subjects use our Grade Calculator.

How can you calculate your GPA?

We will be using Weighted average to calculate your GPA of your total subjects.

The general formula to calculate the Weighted average is:

\overline{x} = \frac{\sum{(x_i \times w_i)}}{\sum{w_i}} = \frac{x_1w_1 + x_2w_2 + ... + x_nw_n}{w_1 + w_2 + ... + w_n}

Where,

• x_i represents each individual value.
• w_i represents the corresponding weight for each value.
• The numerator is the sum of each value multiplied by its weight.
• The denominator is the sum of all the weights.

Example 1 (Percentages):

Let us assume your marks in Math are 80, and the weightage is 30%. Your marks in Science are 90, and the weightage is 30%. Your marks in English are 60, and the weightage is 20%. Your marks in History are 70, and the weightage is 20%.

Weighted Average would be:

\overline{x} = \frac{80 \times 30 + 90 \times 30 + 60 \times 20 + 70 \times 20}{30 + 30 + 20 + 20}

\overline{x} = \frac{2400 + 2700 + 1200 + 1400}{100}

\overline{x} = \frac{7700}{100}

\overline{x} = 77

Your GPA/Percentage would be 77.

Example 2 (Letter Grades with credits):

Let us assume your marks in Math are A, and the credit is 3. Your marks in Science are B, and the credit is 3. Your marks in English are C, and the credit is 2. Your marks in History are D, and the credit is 2.

Weighted Average would be:

\overline{x} = \frac{4.0 \times 3 + 3.0 \times 3 + 2.0 \times 2 + 1.0 \times 2}{3 + 3 + 2 + 2}

\overline{x} = \frac{12 + 9 + 4 + 2}{10}

\overline{x} = \frac{27}{10}

\overline{x} = 2.7

Your GPA would be 2.7.
