Price a School-Run Carpool Stop by Stop — Free, With Fuel and Time
A three-family carpool usually starts as a fair-sounding rotation and drifts into one driver doing the far end of the route every week. The distance each family adds is knowable to within a street, and the cost of that distance is a number nobody puts on the table.

Why the flat version breaks
A rota drawn as a list of names has no distance in it. Adding the stops in order with the distance from the previous stop turns the same rota into kilometres, fuel and minutes, which is the form a fair share can actually be calculated from.
How to use the school-run route form in four passes
Include the pickup points, the school and the return. The order matters: the same stops in a different order produce a different total, which is exactly what a rota argument is usually about.
The map figure is checkable by everyone in the carpool, which is what makes the resulting share acceptable. Guessed distances become the next argument the moment somebody disagrees.
Fuel spend divided by miles driven is the honest number. If you want tyres and servicing included, use a published running-cost figure and say so on the form.
Send the stop list with the running totals so each family can see their own share of the distance. A share that people can verify is the only one that survives a term.
SAMPLE DATA, NOT A VERIFIED CLAIM: the starter record is a four-stop school run with a return leg, costed at 14 cents a mile and eighteen miles an hour. Replace these values with your own source before you rely on anything.
What breaks first
Splitting the rota by number of turns
Three families taking equal turns is not fair if one of them adds half the distance. The strip makes the imbalance visible in a form nobody has to argue about.
Forgetting the return leg
The school-to-home leg is often longer than the outbound one and is where the fuel bill actually goes. Leave it off and the totals understate every driver's cost.
Using motorway fuel economy for a school run
Cold starts, idling at the gate and stop-start traffic roughly double the per-mile cost of a warm motorway run. Entering 45 miles an hour makes the whole exercise look cheap and useless.
What you pay otherwise
| The usual route | What it leaves out | Cost |
|---|---|---|
| A ride-share app | Per-trip fees and surge pricing on a route three families already drive | $8–$22 a trip |
| A school bus pass | Annual cost per child, and the timetable may not fit an after-school club | $300–$900 a year |
| Doing the far end every week | The full fuel and time cost of the route landing on one driver | the whole fuel bill |
| This page + the free school-run route form | Computed in your tab, result on screen before you type anything | $0 |

The companion app runs the same logic with a numbered intake, three starter records, a stateful share link, the one-time printable layer, and the local history shelf.

The full route costing: every stop with distance, running total, drive time and fuel, plus the longest leg and the budget, unlimited re-runs.
The on-screen result is free and complete. The one-time layer adds a tangible file you keep and the saved history that comes with it.
Boundary: This costs a route from distances you enter; it is not a mileage or tax record, and the running-cost figure is only as good as the number you supply. Insurance, licensing and road rules for carrying other people's children are specific to your jurisdiction — check them before agreeing to a shared rota.
