Splitting a whole trip with friends

Trips have many expense categories and people taking turns paying, so it is easy to lose track of who owes whom. Here is how to settle in one go.

Record every expense during the trip

Record as you pay, not from memory at the end. Note who paid, for what, and who shared.

Common categories: lodging, fuel, tolls, food, entrance tickets, and shared souvenirs.

Handle items not everyone shared

Some activities are not shared by all — water sports, or different rooms.

Separate these and assign only those who shared, which is fairer than lumping everything together.

Minimise the number of transfers

Settling item by item is messy. Compute each person's net balance first, then match people who owe money with those who should be reimbursed to reduce back-and-forth transfers.

If A should receive 500, B owes 300, C owes 200: B sends A 300 and C sends A 200 — done in two transfers.

Example: 4 people, 2 days

  • Lodging 4,000 (A paid) ÷ 4 = 1,000 each
  • Fuel + tolls 1,600 (B paid) ÷ 4 = 400 each
  • Food 2,400 (C paid) ÷ 4 = 600 each
  • Diving 1,500 for 3 only → 500 each
  • HarnDuay combines it all and shows who transfers what.

Settle the example all the way through

Assume A paid 4,000 THB for lodging, B paid 1,600 THB for fuel and tolls, C paid 2,400 THB for food, and D paid 1,500 THB for diving. A, B and D joined the dive.

The fair shares are A 2,500 THB, B 2,500 THB, C 2,000 THB and D 2,500 THB. They add to 9,500 THB, matching all four receipts.

A should receive 1,500 THB and C 400 THB; B owes 900 THB and D owes 1,000 THB. One settlement is B paying A 900 THB, then D paying A 600 THB and C 400 THB.

Key takeaway

Record every expense immediately, separate items not everyone shared, and use HarnDuay to net balances and reduce back-and-forth transfers.

FAQ

How to split activities not everyone joined?

Separate them and assign only the people who shared.

Can I reduce the number of transfers?

Yes — compute net balances and settle in bulk; HarnDuay summarises it.
