Weighted scoring, the honest way
List your options as rows and what matters as columns, give each criterion a weight from 1 to 10, then score every cell. The matrix multiplies scores by weights, totals each option and normalizes it to a 0-100 score so different setups stay comparable. The winner is highlighted, the chart ranks everyone, and the sensitivity note tells you whether the decision is solid or a coin-flip, plus which criterion could flip it. Templates get you started for jobs, laptops, vendors, feature prioritization and apartments. Keep multiple matrices, export CSV/JSON or copy a text summary. Completely free, completely private.
How to use the Decision Matrix
This decision matrix ranks a set of options against the things that matter to you. You give each criterion a weight from 1 to 10, score every option on each criterion, and the tool multiplies, adds up and turns each total into a score out of 100. A short verdict then says how close the top two are and which criterion could change the result. Use it for job offers, purchases, vendors, features or any choice with more than one factor.
Step by step
-
Start from a template or the open matrix
On a first visit the page opens on a Choosing a job matrix with three options and seven criteria, ready to score. To start something else, pick from the Template list, such as Laptop purchase, Vendor selection, Feature prioritization (RICE-ish) or Apartment choice, or press + New for a blank matrix. Each one is added as a new matrix, so nothing you made is overwritten.
-
Set up options and criteria
Options are the rows and criteria are the columns. Click any name to type over it. Press + Add option (row) or + Add criterion (column) to add more, and the cross beside a name to remove it. At least one option and one criterion must stay.
-
Weight each criterion
Drag the slider under each criterion name from 1 to 10. The number beside it, such as w9, is the weight. Set weights before you score, so the scores do not sway how much you say each thing matters.
-
Choose the scale and score every cell
Pick a range in the Scores list: 0-5, 0-10 or 0-100. The default is 0-10. Type a score in each cell. Values above the maximum are capped, and an empty cell counts as 0. If you change the scale later, existing scores are converted so the ranking stays the same.
-
Read the ranking
The Score column and the Results chart update as you type. The leading row is highlighted and its bar is green. Read the verdict under the chart before you decide.

Keep, share or back up
Use the Matrix list to switch between saved decisions, the pencil button to rename one and the bin button to delete it. Press CSV for a spreadsheet, JSON for a backup file, Import JSON to load a backup, or Copy summary for a plain text ranking.
Reading the result
- Each score out of 100 is the option's weighted total divided by the best possible total. Example: a blank matrix has Cost at weight 8, Quality at 7 and Speed at 5, so the best possible total on a 0-10 scale is 200. Scores of 8, 6 and 4 give 64 + 42 + 20 = 126, which is 63 out of 100.
- Under each score, the smaller number marked weighted is the raw total before it is turned into a score out of 100.
- The verdict looks at the gap between first and second place. Under 2 points is a statistical tie, under 6 is a close call, under 15 is a solid lead, and 15 or more is a clear win.
- The verdict also names the runner up's strongest case: the criterion where it beats the leader by the most once weights are applied. If that criterion matters more than you weighted it, the result could flip.
- The line beside Results shows how many criteria you have, what the weights add up to, and the scale in use.
Tips and common mistakes
- Score so that higher is always better. For a cost criterion, give the cheapest option the highest score, not the most expensive one. The Feature prioritization template says this outright with Low effort (10 = trivial).
- Avoid two criteria that measure the same thing, such as Price and Value for money. The overlap counts twice and tilts the result.
- If the verdict says statistical tie or close call, look again at the scores you were least sure of, or add a tie breaker criterion.
- Deleting a matrix removes it from this browser for good. Press JSON first if you might want it back.
