High-Depreciation Spending

The purchase that destroys money

A new car doesn't just cost money. It destroys money — reliably, measurably, fastest in the first year — and most buyers finance the destruction and pay interest on it. That sentence contains the whole chapter; the rest is pricing it.

Depreciation is the silent line item: the gap between what you paid and what the thing is now worth. It appears on no statement, triggers no alert, and yet for car-owning households it is routinely among the largest true expenses they have — larger than the fuel, often larger than the interest, sometimes larger than the payment itself in the early years. It goes unmanaged for the usual Track-2 reason: it's invisible. Nobody sends you a bill for the value your driveway lost this month.

The curve, priced

For new cars the curve is brutal: roughly 20% of value gone in year one, and often 50–60% by year five — though industry data puts the average five-year figure closer to 42% lately, with wide variation by type (EVs depreciate fastest; trucks and hybrids slowest).¹ Concretely: a $40,000 new car is worth roughly $32,000 after year one — $8,000 of value gone, about $650 a month — before interest, insurance, or a single tank of gas.

Financing makes it stranger: you pay interest on value that no longer exists. Finance the $40,000, and a year in you're paying interest on a loan balance that may exceed the car's worth — the underwater stretch, where you owe more than the asset. Gadgets run the same curve faster — the $1,200 phone is worth half within a year or two — smaller stakes per item, same shape, often on the same financing.

The honest price, and the used-car arbitrage

The point is not "never buy new" or "never buy nice" — that's the lecturing this curriculum doesn't do, and Volume 2's Spend to Impress Yourself defends spending real money on what you genuinely value, cars included. The point is that depreciation is a price, and it deserves to be read as one before the purchase: the honest cost of a car isn't the sticker — it's (depreciation + interest + insurance + maintenance) per year of ownership. Two cars with similar stickers can differ by thousands per year on that honest metric; the sticker comparison hides it, the per-year comparison reveals it.

Read that way, one arbitrage falls out of the curve's shape: the steepest depreciation is front-loaded, which means the 3-year-old version of the same model — with the steepest stretch already absorbed by the first owner — is one of the most reliably good deals in consumer finance. A comparable 3-year-old car at $25,000 versus the $40,000 new one: someone else's wallet paid the $650-a-month year. Kept ten years, the total-cost gap between "new every 4 years" and "lightly-used, kept long" commonly reaches tens of thousands — a NEST-sized difference produced entirely by where on the curve you board and how long you ride. Income context: that gap is real money at every income, but at $50,000 the "new every few years" habit can quietly be the single largest discretionary wealth leak in the household — bigger than every fee in The Extraction Economy combined.

Where Plenee fits

Vehicles you track in Plenee show up in your NEST at realistic value, not purchase price — so depreciation is visible as what it is: your money, leaving, month by month. That does for the silent line item what this track does everywhere: converts an invisible cost into a number you can weigh. Whether the number is worth it — for the car you love, the reliability you need, the delight that's genuinely yours (Spend to Impress Yourself) — is your call, made with the price tag finally attached.
