A weighted scoring tool for comparing options the rational way. List your choices, set how much each criterion matters, score every option, and get a live ranking with the winner highlighted. It saves on your device, exports to CSV and runs entirely in your browser — fully offline.
How to use Decision matrix
- Name the decision and scale — Give the matrix a title (for example Which laptop to buy) and pick a score scale — 1–5, 1–10 or 0–100.
- Add your criteria and weights — List the things that matter — price, performance, battery — and give each a weight for how important it is. Use + criterion to add more.
- List the options and score them — Add each option as a row and score it against every criterion. The weighted total and ranking update live as you type.
- Read the result and export — The highest weighted total is highlighted as the winner, with a bar chart of all options. Use the CSV button to export the table and results.
Frequently asked questions
How is the winner calculated?
Each option's score for a criterion is multiplied by that criterion's weight, then summed across all criteria. The option with the highest weighted total wins, shown as a percentage of the maximum possible.
What do the weights do?
Weights say how much each criterion matters. A higher weight makes that criterion count more towards the total, so a strong score on a heavily weighted criterion moves an option up the ranking.
Can I export my matrix?
Yes. The CSV button downloads the full table — options, criteria, scores and results — as a spreadsheet you can open in Excel or share.
Is my data saved or uploaded?
Your matrix is saved locally on your device so it's there when you return. Nothing is uploaded — it all runs in your browser.
Is there an example to start from?
Yes. Load example fills in a sample laptop-buying matrix so you can see the structure, then edit it for your own decision.
Tips
- Pick weights before you score, so the scores don't bias how important each criterion feels.
- Keep your score scale consistent — score every option on the same range for a fair comparison.
- Load the example first to see how criteria, weights and scores fit together, then clear it and add your own.
- Export to CSV to share the reasoning behind a decision with your team.
