Decision Matrix (Weighted Scoring)
Make better decisions using a weighted scoring matrix. Add options (products, job offers, apartments), define criteria with importance weights (1-10), score each option (1-5) against each criterion, and see weighted totals. The best choice is highlighted automatically. Export as CSV for further analysis or copy a formatted text summary. All data stays in your browser.

Why Use Our Decision Matrix?
Weighted Criteria Scoring
Each criterion has an adjustable importance weight (1-10) so you can prioritise what matters most. Scores are calculated as weighted averages - a criterion with weight 10 contributes twice as much as one with weight 5. The best option is highlighted automatically.
Flexible Options & Criteria
Add any number of options (products, candidates, apartments) and criteria (price, quality, location). Each option is scored against each criterion on a 1-5 scale. Rename or delete anything at any time - the matrix adapts instantly.
Visual Results & Best Choice
See all options ranked by weighted score with progress bars showing relative performance. The best option is highlighted with a star badge and a green banner showing the score breakdown. The weighted total for each option updates in real-time as you adjust scores or weights.
Export CSV & Quick Presets
Export your decision matrix as a CSV file for further analysis in spreadsheets. Copy a formatted text summary to share with stakeholders. Use the 4 built-in presets (Product Comparison, Job Offer, Apartment Hunting, Course Selection) to get started instantly.
Common Use Cases for Decision Matrix
Product & Purchase Decisions
Compare products by criteria like price, features, build quality, warranty, and customer support. Assign weights based on what matters most to you - the matrix highlights which product best meets your priorities, removing emotional bias from purchasing decisions.
Job Offer Evaluation
Compare job offers across criteria like salary, location, growth potential, company culture, and benefits. Use weights to reflect your personal priorities. See at a glance which opportunity scores highest when all factors are considered together.
Apartment & Housing Selection
Score apartments or homes against criteria such as rent, location, size, condition, and amenities. Weight each criterion by personal importance and export the matrix as CSV to share with housemates or family for collaborative decision-making.
Course & University Selection
Students evaluate courses or universities based on interest, difficulty, cost, location, and career prospects. The weighted matrix provides a quantitative framework for a decision that often feels overwhelming when relying on intuition alone.
Vendor & Service Provider Selection
Businesses evaluate vendors, contractors, and service providers using criteria like cost, reliability, quality, response time, and experience. The weighted scoring ensures that all factors are considered objectively in the procurement process.
Technology & Tool Selection
Developers and IT teams compare frameworks, tools, or platforms using criteria like performance, community support, learning curve, documentation, and licensing. The decision matrix helps technical teams make data-driven technology choices.
Understanding the Decision Matrix
What is a Decision Matrix?
A decision matrix (also called a weighted scoring model, Pugh matrix, or grid analysis) is a quantitative decision-making tool that helps you evaluate multiple options against a set of criteria. Each criterion is assigned an importanceweight, and each option is scored against each criterion. The weighted scores are totaled to reveal which option best meets your priorities - removing emotional bias and gut-feel from important decisions.
How Our Decision Matrix Works
- Define Criteria: Add the factors that matter for your decision (e.g. Cost, Quality, Location). For each criterion, set a weight from 1 (least important) to 10 (most important). Use the quick-set buttons (1, 3, 5, 7, 10) or the dropdown for precise values. You can also load a preset to get started quickly.
- Add Options: List the choices you are comparing (e.g. Product A, Product B, Product C). You can add as many options as you need - the matrix adjusts to show all options with their corresponding score columns.
- Score Each Option: For each option-criterion pair, click a score from 1 (Poor) to 5 (Excellent). Scores are colour-coded (red → amber → blue → green) for quick visual assessment. Click the same score again to deselect it and return to unscored.
- Review Weighted Results: The weighted total for each option updates in real-time. The Results panel shows all options ranked with progress bars, the best choice is highlighted with a star badge and green banner, and you can export as CSV or copy a formatted text summary.
How Weighted Scoring is Calculated
The weighted score is calculated using the formula:
Weighted Score = Σ(score × weight) ÷ Σ(weight)
For example, if an option scores 4/5 on Cost (weight 8) and 3/5 on Quality (weight 6):
Weighted Score = (4×8 + 3×6) ÷ (8 + 6) = (32 + 18) ÷ 14 = 50 ÷ 14 = 3.57 / 5.00
The result is always between 1.0 (all scores = 1) and 5.0 (all scores = 5). The option with the highest weighted score is the best mathematical choice given your priorities. We recommend using the matrix as a guide alongside your intuition - not as a replacement for it.

Frequently Asked Questions About Decision Matrix
A decision matrix (or weighted scoring model) is a tool that helps you make complex decisions by scoring options against weighted criteria. Each criterion has an importance weight (1-10), and each option is scored (1-5) against each criterion. The weighted total shows which option best meets your priorities.
Start by adding criteria (the factors that matter) with importance weights. Then add options (the choices you are comparing). Finally, click score buttons (1-5) for each option-criterion pair. The weighted results update automatically and show which option is the best choice.
Weights reflect how important each criterion is relative to others, on a scale of 1-10. A weight of 10 means the criterion is critically important; a weight of 1 means it barely matters. The weighted score formula uses these weights to compute a priority-adjusted score for each option.
For each option, the tool multiplies each criterion score by its weight, sums them up, and divides by the total weight. This gives a weighted average between 1.0 and 5.0. The option with the highest weighted score is mathematically the best choice given your priorities.

The presets provide ready-to-use criteria and options for common decisions: Product Comparison, Job Offer Evaluation, Apartment Hunting, and Course Selection. Click any preset to load it - you can then customise the criteria, weights, options, and scores as needed.
Yes. All criteria, weights, options, and scores are automatically saved to your browser's localStorage. When you return, your matrix is restored. Use the "Reset" button to clear all data and start fresh.
A pros/cons list treats all factors equally. A decision matrix lets you assign different importance weights to different criteria, and provides a quantitative score rather than a qualitative judgement. This makes it more objective and repeatable for complex decisions with multiple stakeholders.
