Step by step
The formula
grade = Σ(score × weight) / Σ(weights)
A weighted average counts each score in proportion to its importance. Multiply every score by its weight, add them, then divide by the total weight — which means the weights need not sum to 100 for the result to be correct.

Frequently asked questions
What if my weights do not add up to 100?+
That is fine — the tool divides by the total weight, so any consistent weighting works. Leave the weights box empty for a simple average.
