Vehicle Cost Of Ownership Calculator
The sticker price is the least informative number on the lot. A $30,000 car kept five years typically drains more than $60,000 from your wallet once loan interest, fuel, insurance, maintenance, depreciation, and fees are counted. This calculator adds all six together honestly, amortizing the loan properly instead of just multiplying the payment, and shows the true cost per mile and per month. To see how any single car compares on running costs alone, try the cost-per-mile breakdown or estimate fuel spend with the fuel distance calculator.
Planning estimate only. Depreciation and maintenance vary widely by brand and driving habits.
Quick Answer
True cost of ownership is loan payments plus fuel, insurance, maintenance, depreciation, and fees over the years you own the car. For example, a $30,000 car ($5,000 down, 6.5% APR, 60 months) kept 5 years at 15,000 miles a year costs $63,720 all-in: $0.85 per mile, or $1,062 a month, far more than the $489 loan payment alone.
Key takeaways
- The payment is less than half the story: depreciation and insurance often exceed the loan interest.
- Depreciation is the biggest single cost on most cars, and it is invisible until you sell.
- Cost per mile is the honest comparison metric: the IRS values driving at 72.5 to 76 cents a mile in 2026.
- Two cars with similar sticker prices can differ by $20,000 in 5-year cost through fuel and depreciation alone.
Worked example, verified against the tool
$30,000 price, $5,000 down, 6.5% APR over 60 months, owned 5 years, 15,000 miles a year at 32 MPG and $3.50 a gallon, $1,400 insurance, $800 maintenance, 12% yearly depreciation, $200 fees: monthly payment $489.15, loan payments $29,349.22 (interest $4,349.22), fuel $8,203.13, insurance $7,000, maintenance $4,000, depreciation $14,168.04, fees $1,000. Total: $63,720.39, or $0.85 per mile and $1,062.01 a month. Enter these inputs above and the tool returns exactly these figures.
The six costs behind the total
Loan payments are amortized month by month in this calculator, so interest is real interest, not payment times months. Fuel is annual miles divided by MPG times the local price, the EIA publishes weekly regional averages. Insurance uses your actual premium; 2026 national averages run about $187 a month for full coverage according to Insurify’s October data. Maintenance covers routine service plus a repair reserve that grows as the car ages. Depreciation is the value the car loses while you own it, computed as a yearly rate compounded. Fees sweep up registration, inspections, and anything else yearly.
Notice what is not double-counted: the down payment and principal are not added on top of loan payments, a mistake several competing calculators make. You paid the down payment once and the principal through the payments; counting both inflates the total by the price of the car.
Where the money actually goes
For the worked example above, the $63,720 five-year total splits like this:
The loan payment dominates, but depreciation is the silent second place: $14,168 you never see leave until resale day. Insurance and fuel together ($15,203) exceed all the interest paid on the loan.
True cost by vehicle class
Illustrative 5-year totals at 15,000 miles a year, using typical prices, efficiency, and depreciation for each class:
| Vehicle class | Typical price | 5-year total | Cost per mile | Cost driver |
|---|---|---|---|---|
| Economy sedan | $24,000 | ~$48,000 | ~$0.64 | Low depreciation, cheap insurance |
| Midsize sedan | $32,000 | ~$66,000 | ~$0.88 | Balanced across all categories |
| Midsize SUV | $42,000 | ~$82,000 | ~$1.09 | Fuel and insurance climb |
| Luxury sedan | $60,000 | ~$112,000 | ~$1.49 | Depreciation dominates |

Depreciation: the invisible cost
Depreciation is the largest cost most owners never budget for because no bill arrives. A car losing 12% a year sheds $14,168 over five years on a $30,000 purchase, more than triple the loan interest. Brand choice moves this more than any other input: see how fast specific models depreciate before you buy. Keeping a car longer is the most powerful lever against depreciation, since the curve flattens hard after year five while the car keeps serving. For drivers tracking business miles, compare your per-mile result against the standard mileage reimbursement rate to see whether driving your own car actually pays.
The used-car shortcut
The steepest depreciation happens in the first three years, which is why a two-to-three-year-old car is the classic value play: the first owner absorbed the worst of the invisible cost, and you buy the car right as the curve flattens. Run the calculator twice, once with the new price and once with the used price and a lower depreciation rate, and compare the five-year totals side by side. Certified pre-owned programs soften the risk with inspected vehicles and warranty extensions, though the CPO premium narrows the savings. The biggest caveats are financing, since used-car rates run higher, and that older cars face rising maintenance in years four through seven, so raise the maintenance input to reflect it.
What competing calculators get wrong
The common failure is arithmetic, not intent. Several popular TCO pages multiply the monthly payment by the loan term and then add the full purchase price on top, counting the car’s price twice. Others skip depreciation entirely, which removes the single biggest cost and makes expensive cars look cheap. A few more use simple interest instead of amortization. This calculator amortizes the loan month by month, counts each dollar once, and discloses every line item so the total can be checked.
Frequently asked questions
Everything the car costs over the years you own it: loan payments (principal and interest), fuel, insurance, maintenance and repairs, depreciation, and registration and fees. On a $30,000 car kept five years, the true total is often double the sticker price.
Divide the total ownership cost by total miles driven in the same period. The calculator does this automatically. The IRS standard mileage rate (72.5 cents for early 2026, 76 cents from July) is the benchmark most businesses use.
Yes, and it is usually the largest single cost. Depreciation is real money: the difference between what you paid and what you can sell for. Ignoring it is why expensive cars look affordable on a payment-only budget.
Usually a 2 to 3 year old used car: someone else absorbed the steepest depreciation, while reliability and warranty coverage remain strong. Very old cars flip the math as maintenance and repairs climb. Run both scenarios in the calculator with different depreciation and maintenance inputs.
EVs typically win on fuel and maintenance but lose on depreciation and insurance, with the purchase price higher upfront. The winner depends on your miles, electricity rates, and how long you keep the car. Model the EV with lower fuel and maintenance inputs and a higher depreciation rate to compare fairly.
Buy a car that depreciates slowly, keep it longer than five years, shop insurance annually, and drive efficiently. The biggest lever is the purchase itself: a $10,000 cheaper car saves far more than years of coupon-clipping on maintenance.
It is already included through the loan math: a bigger down payment means a smaller loan and smaller payments. Adding the down payment again on top of full loan payments would double-count it, a common error in simpler calculators.
Under $0.60 a mile is efficient for a mainstream car; $0.60 to $0.78 is typical; above that is costly. The IRS reimburses business driving at 72.5 to 76 cents a mile in 2026, which reflects the government’s own estimate of average driving cost.
