Make tradeoffs explicit
A weighted decision matrix compares the same options against the same criteria. Each criterion gets an importance weight, each option gets a score, and the calculator combines those judgments into a ranked total. The value is not mathematical certainty. It is a visible record of what mattered and how the ranking was produced.
Use it for supplier selection, project priorities, product choices, hiring rubrics, or any decision with several credible options and competing factors. If the options are genuinely interchangeable, the random choice picker is the simpler tool.
Transparent scoring
The calculator first normalizes every criterion: criterion weight divided by the sum of all weights. It then multiplies each 1-to-10 score by that criterion's normalized weight and adds the contributions. The result stays on the same 1-to-10 scale, which makes options easy to compare even when your raw weights do not add up to 100.
option total = Σ(score × criterion weight ÷ total weight)
A zero weight keeps a criterion in the worksheet but removes its effect from the result. Equal totals share the same rank, and the original option order is preserved inside a tie.
Suppose cost has weight 5, reliability 3, and delivery speed 2. Option A scores 8, 6, and 7, producing (40 + 18 + 14) ÷ 10 = 7.2. Option B scores 6, 9, and 8, producing (30 + 27 + 16) ÷ 10 = 7.3. Option B ranks first, but the narrow gap tells you to inspect the assumptions before treating it as a decisive win.
Better inputs
Write one decision and one time horizon. Mixing short-term price with long-term strategy without naming the horizon makes the scores hard to interpret.
Agree on what 1, 5, and 10 mean for each criterion before scoring. A 10 for cost should represent the same kind of fit across every option.
Judge each option against the criterion, then look at the totals. Editing scores only to force a preferred result defeats the audit trail.
Change one uncertain weight or score and recalculate. If the winner flips easily, record the decision as sensitive instead of presenting a false margin of confidence.
Paste a list into a random choice picker, choose fairly with browser cryptography, and remove a winner before the next round.
