How to split food costs with friends fairly

Equal split vs itemized split

An equal split divides the total by the number of people. It works when everyone ate similarly, like a fixed-price buffet — fast and simple.

But if one person had a 500 THB steak and another a 120 THB salad, an equal split is unfair. Then an itemized split, charging each person for what they ordered, is fairer.

Rule of thumb: if per-person amounts differ by more than 20-30%, split by what was actually eaten.

Steps for an itemized split

• List every dish with its price from the receipt.
• Mark who ate each dish; some are shared by several people.
• Shared items like rice or water are split only among those who shared.
• Add VAT 7% and service charge 10% proportionally to each person.
• Total per person and note who paid up front for reimbursement.

A worked example

Say three friends: A had steak 500, B pasta 300, C salad 200, plus shared water 90 (30 each).

Food per person: A = 530, B = 330, C = 230, total 1,090 THB.

With 10% service charge (109) and 7% VAT on 1,199 (≈84), the total is about 1,283 THB, each paying proportionally to their own food total.

A lazy equal split would charge everyone 428 THB, clearly penalising C who only had a salad.

Tips to avoid money drama

• Agree on the method before ordering.
• Always photograph the receipt for later checking.
• Use a calculator tool instead of mental math for transparency.
• Have one person pay and everyone transfer back — faster than paying separately.
