Weighted grade calculator

How it works

Each category's weight is multiplied by its score and those products are summed, then divided by the total of all the weights entered — if your weights add up to something other than 100%, the result is still mathematically correct because it's scaled by whatever they actually total, though a warning appears so you can double check them.

FAQ

What happens if my category weights don't add up to 100%?

The calculator still works — it divides the weighted sum by whatever the weights actually total, which mathematically scales the result proportionally, but it also shows a warning so you can check your weights match your syllabus.

Can a category have a weight of 0 to see a hypothetical grade without it?

Yes — set its weight to 0 and it contributes nothing to the weighted sum or total weight, effectively excluding that category from the final grade without deleting the row.
