Trip Expense Splitter

How to split the costs of a trip

1. Pick the currency and add the name of everyone on the trip.
2. For each expense, enter what it was for, the amount and who paid. Then tap the names it should be shared between — leave someone out if they did not take part, for example a person who skipped a dinner.
3. Keep adding expenses as the trip goes on. Balances shows where each person stands and Settle up lists the payments that square everything.

How the split is calculated

For each person the tool adds up what they paid and subtracts their share of every expense they were part of. The result is their balance: positive means the group owes them, negative means they owe the group. All the balances always add up to zero.

Worked example. Anu, Bala and Chitra take a trip. Anu pays ₹3,000 for the hotel and Bala pays ₹900 for dinner, both shared by all three. The total is ₹3,900, so each person's share is ₹1,300.

Two payments settle it: Chitra pays Anu ₹1,300 and Bala pays Anu ₹400.

Why “the fewest payments” matters

If everyone repaid every expense separately, a week away with six people could mean dozens of small transfers. Working from net balances removes the back-and-forth: someone who owes ₹500 to one friend and is owed ₹500 by another pays nothing at all. The tool then pairs the people who owe with the people who are owed until every balance is zero, so a group of any size settles in at most one payment fewer than the number of people.

Tips for a fair split

• Log expenses on the day. It takes seconds and avoids arguments over half-remembered amounts later.
• Be precise about who shared what. Alcohol, an activity only some people did, or a room that slept two rather than three are the usual sources of unfairness.
• Use one currency. If you paid in foreign currency, convert at the rate you were actually charged before entering the amount.
• Settle once, at the end, rather than after each expense.
