CostMe makes the math of every want honest.
Type any price and CostMe shows what that money could become if you invested it instead. One honest number, before you spend, then the decision stays yours.
Spending has never been easier, and saving has never felt harder. The national debt has passed thirty-five trillion dollars, household credit-card balances have crossed a trillion, and a whole industry has grown up around helping you not feel the cost of a purchase in the moment you make it.
For one person at a checkout, that pressure is quiet but real. A forty-dollar habit is not forty dollars. It is the decades of growth that forty dollars would have earned, sitting where you could see it, if anyone ever showed you that number at the right time. Small, repeated leaks are where most of the money goes.
The tools meant to help mostly arrive too late. Budgeting apps tally the damage the day after and dress it up as insight. Buy-now-pay-later splits one decision into four small ones, which is exactly how it slips past the part of you that would have paused. One-tap checkout is built to remove the pause on purpose.
CostMe is what we built instead. A calm room around the one moment that decides everything: the second before you spend. No shame, no lecture, no dashboard to tend. Just the real cost, made visible, so the choice is finally yours to make on purpose.
Three calm tools, one quiet idea.
The idea is opportunity cost: the value of what you give up when you choose one thing over another. CostMe puts that number in front of you in plain language, then gets out of the way.
Calculator

Vault
Not ready to decide? Pause for 48 hours. The Vault holds the choice open so a moment of clarity has room to land.
Amy
An advisor that reflects your own questions back instead of telling you what to do. Amy helps you think it through. You stay in charge.
Honest about the edges.
Not a budgeting app
No envelopes, no spreadsheets, no spending categories to maintain. CostMe weighs one decision at a time.
Not a brokerage
We never hold your money or sell you a product. The investment figure is an illustration, not an offer.
Not therapy
CostMe is a decision tool. It supports calmer choices; it is not treatment or a substitute for care.
Not financial advice
We show the math and hand the decision back to you. What you do with the number is yours.
Behavioral and emotional work is reviewed by a Registered Psychotherapist (Ontario). A licensed clinician reviews how CostMe talks about money so the calm we design for is grounded in real clinical care, and the tone stays supportive rather than shaming.
Four things we hold to.
Money decisions deserve a calm room, not a notification cascade.
Behavioral science should be felt, not announced.
Privacy is the product feature.
You decide. We do the math.
