The formula
share = total paid ÷ people position = amount paid − share
Everyone pays the same share. If someone joined for only part of the trip, split that part separately.
What to watch out for
Add up each person’s receipts first. For a shared car, the road trip cost calculator gives a fuel and tolls figure to add to whoever paid it.
Frequently Asked Questions
How do I split costs when people paid different amounts?
Add it all up and divide by the people. If four people paid 320, 180, 60 and 0, the total is 560 and each share is 140. Anyone above that gets the difference back from anyone below.
How many payments does it take to settle up?
At most one fewer than the number of people, because each transfer can clear at least one person.
