How the weighted score is calculated
Formula
Weighted score = sum(score × weight) / sum of weights.
Score
The rating of a criterion on one common scale, for example 1–10 or 0–100.
Weight
How much a criterion matters. Percentages or any relative weights work.
Result
The final score helps compare options when the criteria were agreed on in advance.

What to avoid
- Choosing weights after the result Fix the weights before calculating, otherwise the score is easy to bend toward the answer you want.
- Mixing scales If one criterion is scored 1–5 and another 0–100, normalize the values first.
- Treating the score as the only truth A weighted score helps compare options but does not replace a discussion of risks and context.
