Splitting the bill on a trip is an art form, comparable to quantum physics, only instead of atoms, you have receipts for pasta and museum tickets. To ensure that by the end of your vacation you still call each other friends, and not “that person who owes me for a magnet,” you need to develop a strategy in advance. We've put together a memo for you on how not to go broke and not to fall out.

Agreement upfront

The most heated disputes arise from unmet expectations. To avoid this, discuss financial etiquette at the airport, when you gather to buy tickets to Belgrade on Kupi.com or any other available destination.

Choosing a strategy

There are three main approaches:

• “Every man for himself”: suitable for short trips or if friends have very different income levels. Waiters in restaurants are immediately informed about separate checks.

• “Common pot”: everyone contributes a fixed amount to a common fund. Everything is paid from it: from gas to magnets. This is convenient if you rent a villa and shop at supermarkets.

• “Digital accounting”: one pays today, another tomorrow, and an app reconciles debits and credits at the end of the trip.

Technology to the rescue

Forget about receipts in your pockets. In 2026, the industry standard is mobile apps for expense sharing (like Splitwise or similar services within banking ecosystems).

• How it works: you create a group “Trip to Romania”, add friends, and enter every expense there.

• Important nuance: enter expenses immediately, before you forget the details. For example, if you decided to buy tickets for the Saint Petersburg – Yerevan route for the whole company with your card, record it at that very minute.

How to split specific expenses

Accommodation

If you book apartments, it's rarely the case that all rooms are identical.

• Fair approach: the one who occupies the “master bedroom” with a private bathroom pays 10-15% more. Those who sleep in the walk-through living room on the sofa pay less.

• Simple approach: we divide the total booking amount strictly equally. This is acceptable if the difference in comfort is insignificant.

Car rental and fuel

Mistakes often arise here. It's fair to split expenses among all passengers, including the driver. The driver expends effort on the road, so exempting them from paying for fuel is good etiquette, but not an obligation.

• Toll roads and parking: these are shared expenses.

• Fines: if the driver exceeded the speed limit on their own initiative – they pay themselves. If the whole company shouted “go, we're late for the plane” – it's worth sharing the responsibility.

Restaurants

The most common reason for dissatisfaction is when one person only eats salad, while the other orders steaks and expensive alcohol.

• Solution: if orders are roughly equivalent – split equally, this will save time. If the difference is large – enter individual amounts into the app. Don't forget to include tips (usually 10%) in each participant's final figure.

Etiquette and delicate moments

• Exchange rates: if you pay in dinars, drams, or lei, and will repay debts in rubles, agree on which exchange rate to use: the Central Bank rate on the day of the expense or the actual card debit rate (which is always higher).

• Debts: set a deadline. It is considered good practice to settle all transfers within two to three days after returning home.

• Spontaneous decisions: if one friend suddenly decides to go to an expensive museum where others don't want to go, they pay for it themselves. Don't impose your paid interests on the group.

Travel is about emotions, not accounting. Use automation, be honest, and don't fuss over a couple of euros – nerve cells are more valuable.
