Multi-criteria weighted scoring with a confidence reading
List options, criteria, and weights; score each option 0–10. The tool returns a weighted total, the best pick, and a confidence bar. Pure browser; no login.

When options have different strengths, a gut decision tends to overweight whatever you thought about last. A weighted decision matrix makes the trade-offs explicit: list what matters, decide how much each criterion counts, score every option against every criterion, and let the arithmetic combine them.
This tool builds the matrix for you. Add options and criteria, give each criterion a weight, score each option from 0 to 10, and read the weighted score, the best option and how complete your scoring is.
Weights: price 3, quality 2, distance 1 Flat A: price 8, quality 5, distance 6 Flat B: price 5, quality 9, distance 9
Flat A: 6.67 Flat B: 7.00 Best option: Flat B (confidence 100%)
Flat A wins on the criterion that counts most, but Flat B's strong scores on the other two add up to more.
Each score is multiplied by its criterion's weight, the products are added up, and the sum is divided by the total weight. The result stays on the same 0 to 10 scale as the scores, so a 7 means the option is about a 7 out of 10 overall. For Flat A that is (8×3 + 5×2 + 6×1) ÷ 6 = 6.67.
Set the weights before scoring, so you cannot tune them to justify a favourite. A useful check is to ask whether you would accept a big drop in one criterion for a small gain in another; if not, the first criterion deserves more weight. Keep the list short, three to six criteria, and leave out anything every option does equally well.
If the winner surprises you, that is useful information. Either a criterion is missing or a weight is wrong, or your instinct is reacting to something the matrix does not capture. Close scores, within half a point, mean the options are effectively tied, and other factors or a coin flip can decide.
It is the share of option-criterion cells you have scored. 100% means every option has a score for every criterion; empty cells count as zero.
Yes. A criterion with weight zero is shown but does not affect the totals, which is handy for testing how much it matters.
No. The calculation happens in your browser and nothing is sent anywhere.
