Broke by Choice

Being broke is expensive. Staying broke is a decision.

The Money Burner

The used car borrower pays 17,000 dollars less and 1,600 dollars more

Less borrowed, more interest. That is not a paradox, it is 11.43 percent against 6.39 – and it is the reason the sensible-sounding choice is often the expensive one.

In the first quarter of 2026 the average American who financed a new car borrowed 43,925 dollars and paid 770 dollars a month[1]. The average who financed a used one borrowed 27,070 dollars and paid 531 dollars[2]. So far, so obvious: the used car is cheaper.

Now the rates. New-car loans averaged 6.39 percent; used-car loans averaged 11.43 percent[3]. Run both to the end and the used-car borrower – who borrowed 16,855 dollars less – pays about 1,600 dollars more in interest than the new-car borrower. The first year alone costs $2,917 in interest, before a single dollar of the car itself is paid down.

Why the cheaper car carries the dearer loan

Because the rate is not about the car, it is about the risk and the collateral. A used car is worth less, depreciates less predictably, and is more likely to be financed by someone the lender is less sure about. None of that is a moral judgement and all of it lands in the same place: on the rate. At the Federal Reserve's own numbers, banks charged 7.14 percent on a 60-month new-car loan in the second quarter of 2026[6] – more than a point above the all-lender average, because captive finance arms of the manufacturers buy the rate down to sell the car.

These are four separate averages, and they do not have to fit together

The average amount financed, the average payment, the average rate and the average term are four figures from the same survey, each averaged over a different set of loans. Feed three of them into a calculator and the fourth will not come out exactly right: at 27,070 dollars, 11.43 percent and 531 a month, our arithmetic says 71 months, while the reported average used-car term is 67.73 months[4]. We show the derived figure and name the gap rather than quietly picking whichever one flatters the point.

The term is doing more damage than the rate

The average new-car loan now runs 69.48 months and the average used-car loan 67.73[4] – both comfortably over five and a half years. And the tail is growing: 35.55 percent of new-car loans now run longer than six years, up from 30.83 percent a year earlier, and 31.54 percent of used-car loans, up from 28.60[5].

A longer term is sold as a lower payment, and it is one. It is also more months of interest on a balance that falls more slowly, against a car that does not care about your schedule. Somewhere around year four, a meaningful number of these loans are worth less than the car they are secured on – which is the moment when trading in means rolling the shortfall into the next loan.

Assumptions behind this calculation

  • The rate you enter is read as a nominal APR and divided by twelve, the way a card statement builds its periodic rate. Taking the twelfth root instead would understate the very number this is about.
  • Calculated month by month in whole cents: interest on first, payment off second. That is the order a bank posts in, and it is the order you can check.

Loaded with the average used-car loan and 50 dollars extra a month. Put in your own balance, your own APR and your own payment – all three are on the statement, and the APR is the one people cannot recall when asked. Then change the extra: on a loan at this rate, a small monthly addition takes months off the end and hundreds off the total, because every extra dollar lands on principal.

What we could not verify

How many borrowers are in negative equity, and by how much. The CFPB has published on it, and its file server refuses automated requests, so we could not read the document ourselves and the figures are not in this article. The same goes for what American households spend on transportation overall: the Bureau of Labor Statistics blocks scripted access to its releases as a matter of policy. Where we could not open the page, the number does not appear here.

What the arithmetic actually argues for

Not for buying new. A new car costs 16,855 dollars more up front in this comparison, and no interest saving covers that. What it argues for is separating two decisions that dealerships deliberately combine: which car and which loan. The rate is negotiable, portable, and comes from a different market than the vehicle – and the monthly payment, the number every conversation on the forecourt is steered towards, is the one figure that tells you nothing on its own.

A payment can be lowered by stretching the term, and it usually is. Ask for the total: amount financed, APR, number of months, total of payments. Those four numbers are on the contract, and the fourth one is the only one that answers what the car costs.

What you can do about it

  1. Get a rate before you get a car

    A pre-approval from a bank or credit union takes an afternoon and turns the dealership conversation from a negotiation about payments into a negotiation about price. If the dealer beats the rate you already hold, take theirs – but you can only know they beat it if you brought one.

  2. Negotiate the price, then the trade-in, then the financing, in that order

    Separately and in that order. Combined, all three can be moved against each other until the payment looks right and the total does not. Separately, each one is a number you can compare against something. This costs nothing but the discipline to answer the payment question with a price question.

  3. Refuse the term extension, or price it first

    Seventy-two and eighty-four month loans exist because they make an unaffordable payment affordable. Before accepting one, run it against a shorter term in the calculator above. If the shorter term is genuinely out of reach, the honest reading is that the car is out of reach – and that is a cheaper thing to find out now.

  4. Put anything spare on the principal, and check that it lands there

    At double-digit rates, extra payments are the highest-certainty return available to a borrower. Two cautions: tell the lender the extra is for principal, not a prepayment of next month's bill, and check the statement afterwards. Both are one line in an online banking form, and both get missed.

Frequently asked

Your term comes out as 71 months, but the report says 67.73. Which is right?

Both, and neither is a mistake. The reported term is the average term across used-car loans; our 71 months is what the average balance at the average rate takes to clear at the average payment. Four averages from the same survey do not have to be mutually consistent, because each one is averaged over a different distribution. We show the derived figure because it is the one the calculator can reproduce from three numbers you can read off your own contract.

Does this mean I should buy new?

No. The new car costs nearly 17,000 dollars more to buy in this comparison, and the interest difference is about a tenth of that. What the numbers argue for is treating the loan as a separate purchase from the car – because it is priced in a different market, by different people, and it is the half nobody shops around for.

Why do the Federal Reserve and Experian give different figures?

Different samples. The Federal Reserve's terms-of-credit table covers finance companies and commercial banks; Experian's covers loans it can see across the credit file, including credit unions and lenders serving weaker credit. The two disagree by a few percent and a few thousand dollars, which is roughly the size of the disagreement you should expect – and a good reason not to treat any single average as your rate.
