About the Trip Cost Splitter
If Ana pays a $300 hotel and Ben pays $90 for gas, both split three ways with Cy, each share is $130.00. Ana is owed $170.00, Ben owes $40.00 and Cy owes $130.00, which two payments settle. Each balance is paid − owed, and personal purchases add to the trip total without creating a debt.
The example trip: hotel $300, gas $90, souvenirs $45
| Traveler | Paid for shared costs | Shared owed | Individual expenses | Balance |
|---|---|---|---|---|
| Ana | $300.00 | $130.00 | $0.00 | $170.00 |
| Ben | $90.00 | $130.00 | $0.00 | -$40.00 |
| Cy | $0.00 | $130.00 | $45.00 | -$130.00 |
Trip total $435.00. Payments: Cy to Ana $130.00 and Ben to Ana $40.00. Cy’s $45.00 of souvenirs is in the total and in his Individual column, not in his balance.
$100.00 split evenly, to the cent
| People | Each share |
|---|---|
| 3 | $33.34, $33.33, $33.33 |
| 6 | $16.67 four times, then $16.66 twice |
| 7 | $14.29 four times, then $14.28 three times |
The leftover cents go to the people with the largest fractions, earlier people first, so the parts always add up to $100.00.
How to use this tool
- Add the travelers. A blank name shows as Traveler 1, Traveler 2 and so on.
- Add each shared expense with its amount, who paid and how it is split: Evenly, Custom Shares (percentages that total 100) or Custom Amounts (dollars that add up to the expense to the cent).
- Add anything one person bought only for themselves under Individual Expenses.
- Read the trip total, then the Per Traveler Breakdown: Shared Owed is that person’s part of the shared costs, Individual is their own purchases and Total is the two added. Net Balance shows what each person paid and what they owe or are owed, and the payments below settle it.
- When someone pays, tick Mark as paid on that payment. It moves under Marked as paid, the balances take it in and the list keeps only what is still owed. Untick it to undo.
Frequently asked questions
- How do you split trip expenses fairly among friends?
- Add up what each person paid, work out what each person owes for the shared costs, and settle the difference. This tool does that: balance = paid − owed, with an even split, percent shares or exact dollar amounts per expense. With Custom Amounts a $300 hotel can be Ana $150, Ben $100 and Cy $50, and Ana, who paid it, is owed $150.00.
- What do positive and negative balances mean?
- A positive balance means the person paid more than their share and is owed money. A negative balance means they owe money. All balances add up to zero. In the example Ana is +$170.00, Ben −$40.00 and Cy −$130.00.
- How is $100 split three ways without losing a cent?
- The tool works in whole cents and gives the leftover cent to the first person: $33.34, $33.33 and $33.33. Six ways it is $16.67 four times and $16.66 twice, which still adds to $100.00.
- How many payments does it take to settle up?
- Up to 16 people with a balance, the tool finds the fewest possible. With balances of +$30, −$10, −$20, +$40 and −$40 that is 3 payments, not 4, because $40 and −$40 settle each other. Above 16 people it uses a greedy list that is short but not always the fewest. A payment ticked as paid leaves the count: in the example, once Cy’s $130.00 to Ana is marked, only Ben’s $40.00 is left.
- What is an individual expense, and does it change who owes whom?
- It is something one traveler bought only for themselves, such as souvenirs or a single room upgrade. It counts in the trip total and in that person’s Individual column, and it creates no debt, because the buyer paid and owes the same amount.
- What happens when I remove a traveler?
- The expenses that person paid are removed, they leave every custom split and their individual expenses are removed. A custom split that no longer adds up to 100% hides the results until you fix its percentages.
