Your Next Car Purchase Could Destroy Your Net Worth | Here's Why

Thinking about trading in your old car for a shiny new one? Before you sign anything, see what a new car actually does to your net worth over the next 5 years — not just the monthly payment. We build a real, side-by-side model in Sheetkeeper.io for someone earning the median single U.S. income (about $66K). They're driving a paid-off 2016 Chevy Traverse and have their eye on a brand-new 2027 Kia Telluride at roughly $52,000. Instead of stopping at the loan amount, APR, or monthly payment, we project the entire financial picture — pay period by pay period — to see where they truly end up. The result is eye-opening. On paper the numbers "work," but keeping the old car puts them near $54,000 in net worth after five years, while buying the Telluride leaves them around $16,000 — about $38,000 behind. We walk through exactly why: interest on a long 72-to-84-month loan, depreciation on a much pricier asset, thinner savings, and the car insurance most people forget to raise. This isn't "never buy a new car." It's the opposite of judgment — it's about pulling the decision forward and seeing the future today. Model it out, understand the real tradeoff, then decide with your eyes open. Maybe you still buy the Kia. Maybe you look at a $30K car, or save first and buy later. The point is to run your own numbers before the dealership runs them for you. The Sheetkeeper.io modeling tool shown here is launching soon — you can join the waitlist now.
