Vehicle ownership research

What does it actually cost to own?

Purchase price isn't cost. CPM counts the money that leaves and never comes back (depreciation, fuel, insurance, repairs, tax, registration, interest) and divides it by the miles you drive. Then it tells you what the upgrade over your current car really costs.

Your scenario

Global assumptions apply to every car. Per-car numbers live on each car's sticker.

Use

Years owned Miles / year Baseline what you'd do instead

Location

ZIP code State Purchase tax % Title fee $

Money financed cases

APR % Loan term mo Cash down $ Trade credit $

Energy today's prices

Regular $/gal Premium $/gal Charging $/kWh Insurance

Advanced assumptions opportunity cost, selling friction, resale mileage sensitivity

Opportunity cost %/yr on equity Selling cost % of exit Resale per 10k mi ± % vs 10k/yr pace Registration start year Non-CO registration $/yr Insurance index × car's base

The spectrum

Every row runs through the same model. Tap a name for its ownership sticker. Grab ⠿ to drag cars into your own order.

Head-to-head

Up to five cars, same assumptions, side by side. Add or remove with Compare on any row.

Find the outliers

Scaled to the main pack of cars. Anything far outside it is pinned to the edge with its value, so one exotic doesn't squash everything else. The dark line is your baseline.

How CPM works

Short version: count the money that disappears, not the money you park in the car.
