Step 1 / 3

Decision Matrix Maker

Compare your options against the criteria and weights you set. Scores are calculated locally with visible arithmetic.

Option

Your options, criteria, weights and scores stay in this browser session. They are not sent to our servers or added to the page address.

Decision Matrix Maker helps you compare choices using the criteria, weights and scores that you enter. It shows how each weighted score is calculated, so you can review the assumptions instead of relying on a hidden ranking. Your matrix remains in your browser session.

Build a transparent weighted comparison

1

Name the options

Add between two and eight options. Use short, distinct names so you can still understand the matrix after printing or exporting it.
2

Choose criteria and weights

Add up to eight criteria and give each a weight from 1 to 10. A higher weight makes that criterion contribute more to the numeric total.
3

Score every option

Choose a 0 to 5 or 0 to 10 scale, then score each option against every criterion. Zero is a valid score, not a missing value.
4

Review the arithmetic

For each option, the tool adds weight multiplied by score divided by the selected scale, then divides by total weight to show a percentage. Print or export the inputs for review.

What the weighted percentage means

For each criterion, the tool calculates weight × score ÷ selected scale. It adds those values for an option, divides by the sum of all weights, and shows the result as a percentage. The number only reflects the criteria, weights and scores you supplied. It is useful for making assumptions visible, not for replacing judgement.

Choice you make	Effect on the arithmetic	What it does not establish
Criterion	Adds one comparison dimension	Whether the criterion is complete or appropriate
Weight from 1 to 10	Changes that criterion’s share of the total	A real-world probability or financial value
Score from zero to the selected scale	Changes one option’s numeric contribution	A fact, prediction, safety assessment or guarantee
Higher resulting percentage	Places that input set higher numerically	Which option you should choose

Use scores carefully

Keep comparable criteria separate. For example, cost, implementation time and data handling can be three criteria; combining them in one broad “quality” score hides the trade-offs. Decide what each end of the scale means before scoring, and use the same definition for every option. Try a second version with different weights when the result depends heavily on one uncertain assumption.

The tool does not recommend or guarantee a decision. It is not a forecast and does not obtain prices, check contracts, assess safety, evaluate people, predict outcomes, identify legal requirements or provide professional advice. For an important purchase, hiring, medical, legal, financial or safety decision, gather appropriate evidence and seek qualified advice where needed.

Privacy and export

Options, criteria, weights and scores stay in browser session storage. They are not sent to our servers or put in the page address. Session storage is not a durable backup and can be cleared when the browser or tab closes. CSV export and printing happen locally; review the exported file before sharing it because it contains the text you entered.

Frequently Asked Questions

No. It only means that option received the highest numeric result from your inputs. The tool does not know whether your criteria, weights or scores are complete or accurate.

For each criterion, the tool multiplies its weight by the option score divided by the selected scale. It adds those contributions and divides by total weight to show a percentage.

Yes. Zero is a valid score and contributes zero for that criterion. It is not treated as an empty field.

No. Options, criteria, weights and scores remain in browser session storage. They are not sent to our servers or placed in the page address.
