Split the cost without a spreadsheet.

How it works

1. 01
   Save your vehicle
   Add its real fuel economy once — Routebook applies it to every trip's distance.
2. 02
   Log costs as you go
   Lodging, food, and tolls — add them to a day as they happen.
3. 03
   Add who's on the trip
   Every cost splits evenly across the people you add — no manual math.
4. 04
   Settle up at the end
   Routebook suggests the smallest number of transfers to even everyone out.
