How to split hen do costs fairly

Decide who benefits from each cost

A restaurant bill for twelve can be divided by twelve. A spa visit for eight should be divided by those eight, not everyone on the guest list. Personal flights and private hotel rooms normally stay personal unless the group explicitly agrees otherwise.

If the group is covering the bride, state that early and decide how her share will be distributed. Do not assume that every guest has agreed to the same arrangement.

Record payers separately from participants

Suppose dinner costs £240 for twelve guests. Four guests each put £60 on a card. Each of the twelve owes £20 for dinner, but each payer has already contributed £60. Record four £60 payments against one £240 expense; do not make four separate dinners.

The same idea works for a deposit paid weeks before the final bill. Keep both payments linked to the same booking so the amount still outstanding is obvious.

Keep the original currency

For a meal paid in euros during a party whose main currency is pounds, keep the euro amount, payer and exchange rate used. That lets everyone understand why the shared amount differs from the card receipt. Don't silently recalculate an old expense at today's rate.

Handle cancellations before settling

When a booking is cancelled, mark whether its deposit was returned. A full refund reduces the shared cost; a lost deposit may still need to be shared by the people who agreed to it. Record the refund rather than deleting the payment history.

Settle up after all final bills and refunds are entered. Keep transfers separate from expenses: a transfer clears a debt, it is not another party cost.

A worked example: deposit, final bill and four payers

Take a separate example of a £600 restaurant bill for twelve people, with all twelve sharing equally. The restaurant took a £120 deposit from Anna and credits it against the final bill. On the night there is £480 left to pay. Anna adds £30, and Beth, Cara and Dina each pay £150. The total paid is £600, not £720: the deposit was part of the bill, not an extra charge.

Each guest’s share is £50. Each of the four payers has contributed £150 in total and should receive £100 back. Each of the eight other guests owes £50. The £400 owed by the eight guests matches the £400 due back to the four payers. This is a useful check before sending payment requests.

You can keep several linked payment records, but the restaurant cost must only be counted once. A booking estimate is not another expense, and recording a bank transfer between guests must not increase the meal’s total. Keep receipts and payment dates available so corrections are easy to explain.

Decide what happens if someone cancels

Agree the approach before collecting deposits. Some costs change with attendance, such as an unconfirmed meal; others may already be committed, such as a non-refundable place. Ask the provider what can actually be changed before promising a guest a refund. This is about the group’s agreement and the supplier’s terms, not a universal rule that an absent guest must pay.

For an illustrative £120 deposit where £90 is returned and £30 is retained, record the original payment and the £90 refund. The remaining shared cost is £30, allocated to the people who agreed to cover that risk. If the refund went back to the organiser’s card, it also changes how much that organiser should receive from the group.

If a replacement guest takes a place, agree who reimburses whom and update participation without charging both people for the same place. Keep the original payment trail. Deleting a person from a guest list should not erase money they paid or money already returned to them.

Handle unequal shares, room nights and currency clearly

Equal shares are appropriate when everyone agreed to the same benefit. For private rooms, different numbers of nights or optional activities, agree a basis that reflects what people use. A guest staying one night should not automatically receive the same accommodation share as someone staying three. Write the rule down before paying, including whether a fixed property fee is split separately.

For a foreign-currency receipt, record the original amount and the conversion you agree to use. As an illustration only, €240 at £0.85 per euro is £204; divided among twelve, that is £17 each. This is not a current exchange-rate quote. If the card was actually charged a different sterling amount or a separate fee, show the adjustment explicitly rather than silently changing the figures.

Round at the smallest currency unit and make sure the allocated shares still add up to the recorded total. Any leftover penny belongs in the visible allocation, not in an unexplained balance. Avoid converting the same expense back and forth when different guests look at it.

A calm final settle-up message

Before requesting transfers, check every expense against its receipt, confirm all participants and ask the group about anything still missing. Show amounts already paid alongside each person’s share. People should be able to understand their balance without trusting a mysterious total.

A useful message might say: ‘Your shared costs are £95. You paid £60 towards the restaurant, so £35 remains. The cancelled activity refund is already included. Please check the entries before transferring.’ Use each guest’s actual figures, and include only the payment details they need.

Mark a settlement only when the transfer has been received or otherwise confirmed. If someone sends the wrong amount, record what actually arrived and leave the remainder visible. Close the party’s costs after outstanding refunds are resolved, while keeping the history available for later questions.
