Vacation Cost Split Calculator

How it is calculated

The trip cost is split equally and deposits are netted off: per_person_share = total_trip_cost ÷ num_travelers, balance_due = per_person_share − already_paid_per_person, total_paid_so_far = already_paid_per_person × num_travelers and remaining_total = total_trip_cost − total_paid_so_far. The deposit field is one amount that applies to every traveler, so it suits groups where everyone paid the same. It must be filled in (use 0 if nothing has been paid). If deposits exceed the share, the balance and remaining total turn negative and print with the sign first, such as -$200.00, which means money is owed back. No result is shown for a traveler count below 1 or with a fraction (2.5), a negative cost or a negative deposit. It is an even split only, with no itemising of extras.

Common mistakes

• Entering the total of all deposits in the per-person field. The field is the deposit of one traveler, and the tool multiplies it by the group size itself.
• Using the tool when deposits differ. It assumes the same deposit for everyone, so for uneven deposits work out each person's balance separately or use the average only to see the group total.
• Counting children who travel free or at a discount as full travelers. An even split overcharges them; subtract their fares first or treat them separately.
• Entering a half traveler such as 2.5 to account for a child. The count must be a whole number, otherwise no result is shown.
• Reading a negative balance as a mistake. It means that traveler has paid more than their share and is owed money back; with $1,000 each on the example trip, the balance reads -$200.00.
