Our Grade Calculator calculates the final exam grade you would need to get a desired overall course grade and would require you to input your current course percentage grade as well as the weight of the final as a percentage. If you do not know your current grade, you would need to select "no" on the question "Do you know your Current Grade?" and then input the grades you received for your assignments, tests, homework, labs, etc. as well as the weight as a percentage of each. Our grade calculator automatically calculates your current grade as well as the grade needed on the final exam to get your desired overall course grade! Not only that but the minimum and maximum course overall course grades are also calculated. Furthermore, a table and chart of the different possible final exam grades and their corresponding overall course grades are also generated, all automatically.
When inputting your Current Grade and the Weight of the Final, our calculator automatically assumes that your current grade is based is based on weight of your course prior to the final exam and is calculated as 100% minus the inputted weight of the final. If your current grade does not account for all the course work (assignments, labs, tests, homework, etc.) prior to your final exam then the calculator results will not be accurate for you.
Similarly, if you don’t know your Current Grade and you input your course work and corresponding grades and weights into our calculator, the calculator automatically calculates your current grade as well as the Weight of the Final. In this case the weight of the final is simply calculated as 100% minus the Sum of the Weights of your course work. Thus if you inputted too many or too little assignments, tests, etc. then the Weight of the Final calculated may not match the actual weight of the final in your course.

Weighted grade calculation
The weighted grade is equal to the sum of the product of the weights (w) in percent (%) times the grade (g):
Weighted grade = w1×g1+ w2×g2+ w3×g3+...
When the weights are not in percent (hours or points...), you should also divided by the sum of the weights:
Weighted grade = (w1×g1+ w2×g2+ w3×g3+...) / (w1+w2+w3+...)
3 points Math course with grade of 80%.
5 points Biology course with grade of 90%.
2 points History course with grade of 72%.
The weighted average grade is calculated by:
Weighted grade =
= (w1×g1+ w2×g2+ w3×g3) / (w1+w2+w3)
= (3×80%+ 5×90%+ 2×72%) / (3+5+2) = 83.4%
