Decision Matrix Calculator (weighted scores to compare options)

How it works

Weighted score of an option = Σ (weight × score) ÷ Σ weights, so it stays on the same scale as your scores (for 1–10 scores, a result from 1 to 10). List the criteria that matter (for a job: pay, commute, team…), give each a weight for its importance, then score every option on every criterion in the same order. The option with the highest weighted score ranks first; if two options tie, the one listed first is shown first.

FAQ

How do I choose the weights?

Ask how much each criterion matters compared with the others. If pay matters about twice as much as the commute, give pay 4 and commute 2. The weights do not need to add up to 10 or 100.

The winner does not feel right — now what?

That is useful information: either a criterion is missing or a weight is off. Adjust and look again; the matrix is there to make your reasons visible, not to decide for you.
