Formula

Cars = Math.max(Math.ceil(people/seats),Math.ceil(luggage/boot)); Spare seats = Math.max(Math.ceil(people/seats),Math.ceil(luggage/boot))*seats-people; Spare volume = Math.max(Math.ceil(people/seats),Math.ceil(luggage/boot))*boot-luggage

Worked example

Inputs

People: 13 people
Seats: 4 passenger seats/car
Luggage: 900 L
Boot: 300 L/car

Expected results

Cars: 4 cars
Spare seats: 3 seats
Spare volume: 300 L

How to use this tool

Enter the measured quantities and your own planning assumptions.
Review all calculated outputs and the stated limitations.

Try this example

{
  "people": 13,
  "seats": 4,
  "luggage": 900,
  "boot": 300
}

Accuracy and scope

Seat inputs exclude drivers unless drivers are included in people. Volume is an aggregate lower bound; shapes, weight and legal occupancy must be checked.
