Transportation True Cost Calculator

Most people budget for a car payment and call it done, but the payment is usually the smallest piece of what a car actually costs. This calculator adds up six real monthly line items — loan or lease payment, insurance, gas or charging, maintenance and repairs, parking, and a catch-all for car washes and tolls — into one Total Car Cost figure, then stands that number next to whatever you spend on public transit, rideshare apps, and bike upkeep. Whichever of the four options comes out lowest is flagged as the cheapest, and the gap between that option and your current car cost is projected out to an annual savings figure so a monthly difference that looks trivial (say, $60) reads as what it really is over a year ($720).

It also divides your total car cost by monthly miles driven to give a cost-per-mile figure, which is handy for comparing against the IRS standard mileage rate or a per-mile rideshare estimate. The biggest thing to get right here is completeness on the car side: irregular costs like annual registration, a new tire set, or an unplanned repair rarely make it into a "typical month" estimate, which quietly understates true car cost and makes owning look more competitive than it is. It's also worth remembering this is a pure cost comparison — it doesn't weigh time, convenience, weather exposure, or the flexibility of having a car on demand, all of which matter just as much as the dollar figure when deciding how you actually want to get around.
