Car Cost Calculator

What a car really costs to own

The sticker price and the monthly payment are only part of what a car takes from you. This car cost calculator adds up the cash that actually leaves your account each month — financing, insurance, fuel, maintenance, and any transit passes or rideshare — so even a paid-off car shows its real running cost rather than zero.

Cash vs. depreciation

There is a second cost you never write a check for: depreciation, the value your vehicle quietly loses over time. We show it separately (roughly 18%/yr when new, 12% used, 8% older) instead of hiding it in the headline, because it is real money but not a bill. Your true monthly cost is the cash plus that silent loss.

Every vehicle, side by side

Add as many cars, motorcycles, or transit lines as you actually use and the calculator totals them, so a two-car household sees the whole picture instead of guessing at it.

It feeds your wider picture

Your auto insurance flows to the Insurance calculator and your total transport cost into your Budget, so getting around is counted once, in context.

Use it to decide, not just tally

The real value of a true monthly cost is comparison. Put your current car next to a cheaper one, a used model beside a new one, or driving against a transit pass, and the honest all-in numbers — cash plus depreciation — tell you which actually costs less, rather than which has the smaller sticker or monthly payment.

What it really costs

The loan payment is usually less than half the picture — the true monthly cost of owning a car works through insurance, fuel, maintenance, and depreciation with full numbers.
