Grade Calculator - Calculate Weighted Average Online

Weighted Grade Calculator

You can use your mobile or computer calculator for calculating grades manually. But it’s not a convenient way to do so. It will take a lot of time to figure out. Most importantly, no one can guarantee that the end result is true or not. That’s why it is recommended to use the online grade calculator tool. It will never give false output. Because it is working on programmed algorithms.

Definition, Formula & Calculation

First of all, let me tell you the definition of weighted grade calculation.

Definition: The weighted grade is equal to the sum of weight(W) in percentage(%) multiply by grades(G). So, the formula is like this:

Weighted Grade =
W1 × G1 + W2 × G2 + W3 × G3 + W4 × G4 + W5 × G5 + …

Now let’s take some examples to understand it more deeply.

Example 1

Assume that:

Math course with a grade of 90 and a weight of 20%.
Physics course with a grade of 80 and a weight of 40%.
Social Science course with a grade of 85 and a weight of 25%.

So, the weighted grade calculation is as below:

Weighted Grade =
w1 × g1 + w2 × g2 + w3 × g3 =
(20% × 90) + (40% × 80) + (25% × 85) =
18 + 32 + 21.25 =

Now, if the weights are not in percentage(If it’s in hours or points) then we need to divide achieved grades by the sum of all weights.

Therefore, for three subjects the calculation is look like this:

Weighted Grade =
(W1 × G1 + W2 × G2 + W3 × G3)
(W1 + W2 + W3)

So, the final calculation is:
(20×90 + 40×80 + 25×85) / (20 + 40 + 25) =
7125 / 85 =

Example 2

Let’s take:

5 points Math course with a grade of 90.
4 points Physics course with a grade of 85.
2 points Social Science course with a grade of 75.

So, the Grade =
(W1 × G1 + W2 × G2 + W3 × G3) / (W1 + W2 + W3)
(5×90 + 4×85 + 2×75) / (5 + 4 + 2) =
(450 + 336 + 150) / 11 =

Above all calculations are used to calculate your exam or semester grades online. So, you can use this formula and calculate your school or college grades online.

step1 - Choose Grade Calculator type

Step 2: Enter the Values

Now the second step is entering the values as per your need. Most importantly, you have to enter the values as per the calculation type.

If you choose the Percentage then you have to enter Grade(%) and weight.


If you are calculating Letters then firstly, you can select the grade and then enter the credit.


For Points calculation, you can enter Grade(points) and Max Grade(It is optional).


Step 3: Enter Goal/Required Grade

Another useful option in the grade calculator is that you can set your goal grade. So, you can find how much more grade is required to reach your goal. But it is optional. You can leave it if you don’t want to use it. However, if you use it then you can see the addition grade needed to reach the aim grade.

step3 - Enter Goal Grade in Weighted Grade Calculator

Step 4: Hit Calculate Button
