How a weighted grade is calculated
- Turn each score into a percentage: score ÷ out of × 100.
- Multiply each percentage by its weight and add them up: Σ (percentage × weight).
- Divide by the total weight. If the weights add up to 100%, that's your final grade; if they add up to less, it's your grade so far.
- Final exam needed = (target − grade so far × (1 − final weight)) ÷ final weight.
Frequently asked questions
What if my weights don't add up to 100%?
The calculator divides by the total weight you entered, so with only some items graded you get your current average. It shows the weight total so you can spot a typo.
How do I calculate my grade so far?
Fill in the items you already have and leave the rest blank. The result is the weighted average of the graded items.
How much do I need on the final to pass?
In the final-exam box, enter your current grade, how much the final is worth and the grade you need (e.g. 60). The answer is the minimum final score.
