What is a Decision Matrix?
A decision matrix (also called a weighted scoring model or Pugh matrix) is a structured method for evaluating multiple options against a set of criteria, each assigned an importance weight. This free online decision matrix tool lets you score options on a 1 to 10 scale across weighted criteria and instantly see which choice wins, with no sign-up, no data upload, and no software to install.
Whether you are comparing job candidates, choosing a tech stack, evaluating vendors, or picking a new office location, this tool removes gut-feeling bias and gives you a clear, numbers-backed recommendation. Everything runs in your browser and auto-saves locally, so your data stays completely private.
How to Use This Tool
Follow these steps to compare options with weighted scoring using this free online decision matrix:
Add your criteria - Type each factor that matters to your decision (e.g. Cost, Quality, Speed) and assign an importance weight from 1 (low) to 10 (critical). Or choose a quick-start template like Hiring Decision, Tech Stack Choice, Vendor Selection, or Location to pre-fill common criteria.
Add your options - Enter the choices you are evaluating (e.g. Candidate A, React, Vendor X). You can add as many as you need.
Score each option - A scoring table appears automatically. Rate each option from 1 to 10 on every criterion. Be honest and consistent with your scale.
Calculate the winner - Click the "Calculate Winner" button. The tool multiplies each score by its criterion weight, totals everything up, and shows a visual bar chart ranking all options by their weighted percentage.
Export your results - Download the complete matrix as JSON (for further analysis) or CSV (for spreadsheets). Share the data with your team or archive it for future reference.
Key Features
Weighted criteria scoring - Assign importance weights (1 to 10) so critical factors count more than nice-to-haves in the final calculation.
Quick-start templates - Four built-in presets (Hiring Decision, Tech Stack Choice, Vendor Selection, Location/Office) with pre-configured criteria and sample options to get started in seconds.
Visual results chart - Animated bar chart instantly shows the winner highlighted with a gradient and all other options ranked by percentage score.
JSON and CSV export - Download your complete decision matrix data for use in spreadsheets, reports, or team presentations.
Auto-save to browser storage - Your criteria, options, and scores persist automatically in localStorage. Close the tab and come back later without losing your work.
100% private and offline - No data leaves your browser. No accounts, no servers, no tracking. Works without an internet connection after the page loads.
Common Use Cases
Product managers use this decision matrix tool to prioritize features by scoring them against impact, effort, and strategic alignment. Engineering teams compare frameworks and libraries by weighing performance, ecosystem maturity, learning curve, and scalability. Hiring managers evaluate job candidates objectively by scoring technical skills, culture fit, communication, and growth potential with predetermined weights. Procurement teams compare vendor proposals against cost, reliability, support quality, and integration ease. Students and researchers use it for structured comparison in academic papers. Anyone facing a complex choice with multiple factors benefits from removing emotional bias and seeing a data-driven result.
Frequently Asked Questions
How does the weighted scoring calculation work?
Each option receives a score (1 to 10) for every criterion. That score is multiplied by the criterion's weight. All weighted scores are summed to produce a total. The final percentage represents how close the option came to the maximum possible score (if every criterion scored a perfect 10). The option with the highest percentage wins.
Is my decision data stored on a server?
No. All your criteria, options, scores, and results are stored exclusively in your browser's localStorage. Nothing is transmitted to any server. Your decision data remains completely private on your device. Clearing your browser data will remove the saved state.
Can I use this decision matrix for team decisions?
Yes. Set up your criteria and options, then have each team member score independently on their own device. Export each person's results as CSV, combine them in a spreadsheet, and average the scores for a fair group decision. The JSON export also works well for programmatic aggregation.
What is a good weight scale to use for criteria?
Use the full 1 to 10 range to create meaningful differentiation. A weight of 10 means the criterion is absolutely critical (a dealbreaker). A weight of 1 means it barely matters. Avoid giving every criterion the same weight, as that defeats the purpose of weighted scoring. A good practice: pick your most important factor and give it a 9 or 10, then rate everything else relative to that anchor.
How many criteria and options can I add?
There is no hard limit. You can add as many criteria and options as your decision requires. However, for practical usability, 4 to 8 criteria and 3 to 6 options work best. Too many criteria dilute the importance of individual factors, and too many options make the scoring table hard to fill out consistently.
