About this calculator
A grade calculator finds your overall course grade from the scores you earned on each component and how much each is worth. It multiplies every score by its weight, adds them up and divides by the total weight — so it works even if your weights do not add up to exactly 100%. It also shows the equivalent letter grade.
Frequently asked questions
How is a weighted grade calculated?
Each score is multiplied by its weight, the results are summed, and the total is divided by the sum of the weights. With an 85% homework (20%), 90% midterm (30%) and 88% final (50%), the grade is (85·20 + 90·30 + 88·50) ÷ 100 = 88%.
What if my weights do not add up to 100%?
That is fine here — the calculator divides by the total weight you entered, so a partial gradebook still gives your current standing. It shows the total weight used so you can see how much of the course is accounted for.
What if my weights do not add up to 100%?
That is fine in overall mode — the calculator divides by the total weight you entered, so a partial gradebook still gives your current standing, and it reports the total weight used so you can see how much of the course is accounted for.
