About CompareToDecide
We build free, structured decision-making tools grounded in established decision science — not gut feelings dressed up as data.
Our methodology
Every tool on this site is built around the weighted decision matrix, a technique used in operations research and management science for decades (often called a Pugh matrix or weighted scoring model). The method is simple but rigorous:
- Identify the options being compared.
- Identify the criteria that matter, independent of the options.
- Assign each criterion a weight reflecting its relative importance.
- Score every option against every criterion on a consistent scale.
- Multiply each score by its criterion's weight and sum the totals.
This structure forces two things that ad-hoc decision-making usually skips: separating "what matters" from "how each option performs," and making the tradeoffs explicit rather than implicit. Research on decision fatigue and choice overload consistently shows that structured frameworks reduce regret and second-guessing compared to unaided intuition.
Why we built this
Spreadsheets can do this math, but almost nobody builds one for a phone purchase or a job offer — the setup cost isn't worth it for a one-off decision. Review sites solve a different problem: they aggregate other people's opinions, but they don't know your personal weights. We built a set of instant, no-signup tools that do the weighting and the math for you, so the structured approach is actually usable in daily life.
Who this is for
Our tools are used by consumers comparing purchases, professionals evaluating vendors or job offers, and students choosing between colleges or programs. Every tool follows the same three-step pattern — input, submit, results — so once you've used one, you know how to use them all.
