We are not here to talk you out of buying things. We are here to make sure you know exactly what a big purchase costs before the money moves — and then it is your call.
Most money software is a scold. A category you have blown through, a bar that turns red, a notification about takeout. The implied message is that spending is a failure of discipline and a good month is one where you wanted less.
That framing is useless, because you are going to buy a car anyway. The question was never whether to spend — it is what a specific purchase actually costs you over the years you own it, and whether you would still make it knowing the real number.
A payment is the one figure that can be made to look like anything. We price all seven components and convert each to a monthly figure.
Loan payment — principal and interest, set by price, APR, and term.
Sales tax — charged on the purchase price, financed or paid upfront depending on your state.
Insurance delta — the increase over what you already pay, not your whole premium.
Fuel or charging — computed from your actual annual mileage, not the window sticker.
Maintenance and tires — low and predictable early, rising with age.
Registration and fees — annual, so divided by twelve rather than ignored.
Depreciation — the value the vehicle loses while you own it, usually the largest line, and the one that never appears in your transactions.
Not a percentage of gross income, and not what a lender approved you for. We start from what is genuinely left after the expenses you actually have, then find the largest purchase whose full monthly ownership cost fits inside it.
The down payment is bounded by cash you can actually reach, because a retirement account is not a down payment. The result is a ceiling, not an instruction.
Before you buy, you see the projected effect across every component of your financial health — savings rate, liquidity, debt load, emergency fund, diversification, retirement progress, and net worth trajectory. That is the difference between affordable and advisable.
Once the envelope exists, we search for vehicles that actually fit inside it and show what is genuinely for sale — each linked back to the listing it came from, with the VIN checked against the federal vehicle database.
Cars and housing are live today, in early access. Large durable goods are in development — each category gets its own explorer, because a car depreciates against an auto loan, a house appreciates against a mortgage with escrow, and a watch is usually cash.
