Dividir Custo da Viagem

Splitting travel costs fairly

The easiest way to split is an even one, share = total / n_people, so a R$ 3,500 trip among 4 travelers comes to R$ 875 a head. Things get messier when the trip isn't even, and that's where a weighted split earns its keep. Someone who showed up for only 5 of the 10 days pays half, and whoever skipped a paid activity drops off that line entirely. The cleaner approach is to break the total into categories (lodging, transport, food, activities) and divide each one among the people who actually used it. Keep tips on their own line, since the norm swings a lot by country (US ~18–20%, Europe ~10%, Japan rarely tipped). For trips abroad, pin the exchange rate to the day each expense was paid, and you'll save yourself an argument later. Apps like Splitwise and Tricount handle the arithmetic and settle everyone up with the fewest transfers possible.

Applications

Handy for group trips, backpacking, bachelor and bachelorette parties, family vacations, corporate retreats, or a shared Airbnb. Basically any time a group puts money in up front and squares up once it's over.

FAQ

What if one person paid everything? Work out each person's share, then subtract whatever they've already spent. A positive difference is what they owe; a negative one is what's coming back to them.

How do I handle people who joined late? For fixed costs like a full week of lodging, divide by how many people stayed each night. For the daily variable costs, charge only the people who were actually there that day.

Should tips be split? Yes, as long as the whole group got the benefit of the service. Put them in their own category so the numbers stay easy to follow.
