The five-year number
Almost everyone shops a car on one figure — the payment — and then lives with five. Here is the same used car projected across sixty months with all five lines showing, built from assumptions you can see and change.
A car is not a purchase, it is a subscription with an entry fee. The payment is the part you agree to at a desk; the other four lines arrive quietly, at gas stations and repair shops and in an insurance renewal you skim. None of them is a surprise. All of them are arithmetic.
So here is a projection. It is not a study, a survey or an average — it is one illustrative car under stated assumptions, computed to the cent, with the columns and the rows both adding to the same total. Change any assumption and the totals move; that is the point of showing them.
The car. Financed $16,000.00 at an illustrative 8.75% APR over 60 months — payment $330.20, with a final payment of $329.86.
Fuel. 12,000 miles a year at 30 mpg, fuel at $3.40 a gallon. That is 400 gallons, or $1,360.00 a year, held flat across the five years for legibility.
Insurance. Assumed at $1,560 in years one and two, $1,500 in years three and four, $1,440 in year five — easing slightly as the car ages.
Tires. One set, $900, in year three.
Service. An assumed schedule: routine years, one heavier year, one brake year. $220, $640, $300, $980, $420.
| Line | Year 1 | Year 2 | Year 3 | Year 4 | Year 5 | Total |
|---|---|---|---|---|---|---|
| Loan payments | $3,962.40 | $3,962.40 | $3,962.40 | $3,962.40 | $3,962.06 | $19,811.66 |
| Fuel | $1,360.00 | $1,360.00 | $1,360.00 | $1,360.00 | $1,360.00 | $6,800.00 |
| Insurance | $1,560.00 | $1,560.00 | $1,500.00 | $1,500.00 | $1,440.00 | $7,560.00 |
| Tires | — | — | $900.00 | — | — | $900.00 |
| Service | $220.00 | $640.00 | $300.00 | $980.00 | $420.00 | $2,560.00 |
| Year total | $7,102.40 | $7,522.40 | $8,022.40 | $7,802.40 | $7,182.06 | $37,631.66 |
| Running total | $7,102.40 | $14,624.80 | $22,647.20 | $30,449.60 | $37,631.66 |
Every column adds to its year total and every row adds to its line total; both routes reach $37,631.66. The payment row is a real 60-month amortization schedule, which is why year five is 34¢ light — that is the final payment, exactly as it would be on a contract.
The shape of each year
The totals are similar. What is inside them is not.
Each bar is drawn directly in proportion to the dollars in that year's column, so the widths are the figures — nothing is adjusted to look tidier.
Three things the table says out loud
The payment is a little over half of it
$19,811.66 of the $37,631.66 is the loan. Everything else — $17,820.00 — is the cost of the car simply existing, and almost none of it was discussed at the desk. Shopping on the payment means negotiating hard over 52.6% of the number and ignoring the rest.
The quiet years are the expensive ones
Year three is the largest at $8,022.40, and nothing dramatic happened in it — a set of tires. Year four is second, on routine brake work. The two years with no event at all, one and five, are the cheapest. Cars do not have good years and bad years so much as they have years with wear items falling due and years without.
The number that keeps going after the loan stops
Strip the payments out and the car still costs $3,564.00 a year — $297.00 a month — to keep on the road under these assumptions. That is the figure worth carrying in your head, because it is the one that does not end in month 60.
Two ways to say the same total
$37,631.66 over 60 months is $627.19 a month. Over 60,000 miles it is $0.627 a mile. Both are true, and which one is useful depends on your life: if your mileage is fixed by a commute, the per-mile figure compares cars properly; if your mileage is discretionary, the monthly figure tells you what the car costs whether you drive it or not.
What this table deliberately leaves out
This is a cash projection — money leaving your account — and there are real costs that never appear in one.
Registration and inspection are not here; they are small and they vary. Tolls, parking and the occasional windshield are not here. And the largest omission is the value the car quietly loses while you own it, which costs you nothing each month and everything on the day you sell. That one has its own chart, because it behaves nothing like a bill.
There is also no repair bigger than routine in this table. Five years is long enough that something unbudgeted is likely; we have not invented a figure for it because we would be guessing. The honest way to hold that open is a line of your own, at whatever number would not ruin your year.
Build your own version
The exercise takes twenty minutes and it changes what you shop for. Get an actual insurance quote on the specific car — the VIN, not the model — before you buy it, because that line is the second largest in the table and it is knowable in advance by anyone willing to make a phone call. Look up the fuel economy for that exact engine and trim on the EPA's own site, fueleconomy.gov, rather than trusting the number in a listing. Then put the four non-payment lines next to the payment and see whether the car you were about to buy is still the cheapest one you were considering.
It very often isn't. A car that is $1,500 cheaper on the windshield and $400 a year worse on fuel and insurance has given the whole discount back inside four years — which is the sort of thing that only shows up when all five lines are on the same page.
Every figure here is computed from the stated assumptions and verified two ways: rows sum to line totals, columns sum to year totals, and both routes agree at $37,631.66. The APR, insurance, tire, fuel and service figures are illustrative assumptions chosen to make the arithmetic legible. They are not averages, survey results or quotes, and they are not a prediction of what any particular car will cost. Nothing on this page is financial advice or an offer of credit.
