What does your vehicle really cost you?

AutoLedger adds up everything a vehicle costs, to the cent: fuel and electricity, financing, depreciation, tires, tolls, maintenance and insurance. Electric, hybrid or combustion, on your own server.

TCO dashboard of a petrol city car: total cost, full cost per km, fuel and tolls, monthly trend

Features

One ledger, every cost

One cost ledger feeds every figure you see, so the cost per km on the dashboard is the sum of what you actually paid.

A full TCO engine

Cash purchase, loan or lease, resale value and the real cost per km, net of carpooling revenue and tire wear.

Bring your data your way

Add data by hand, from your phone, by CSV, through the API or automatically with Home Assistant and TeslaMate.

Data sources

Your data, wherever it comes from

Enter it by hand, or let it flow in automatically. AutoLedger is not tied to any brand.

Home Assistant module

Follows the odometer, trips and battery of your vehicle, and your charges when a wallbox is connected to Home Assistant. Installed through HACS.

Home Assistant module Compatible integrations

TeslaMate sync

For a Tesla already logged by TeslaMate: connect your TeslaMateApi and AutoLedger imports the odometer, trips and charges. No Home Assistant needed.

Assistants

Ask your assistant what your car costs

Turn on the MCP endpoint and Claude, Cursor or any MCP client can answer questions about your costs, from your own server.

Read-only. Nothing an assistant can call changes your account.
You choose the vehicles it can read, all or only some, on a consent page you approve.
VINs, plates, GPS positions and documents are never served.
See what it did. The account page lists the last 50 calls of each access, and one click cuts it off.

Household fleet comparing an electric car and a petrol car

Screens

Clear on a desk, quick in a pocket

Compare every vehicle of the household on the same real cost per distance.
Add a fill-up in a few taps from your phone, even without a network: entries are queued and sent later.
See what is missing: a completeness score tells you which data would sharpen the result.
