The Short Answer
In the United States, plan on US$5 to US$10 a night for housekeeping, US$5 for the first bag and US$2 to US$5 for each one after, US$2 to US$5 each time the valet brings the car, and US$10 to US$20 for a concierge who solved something genuinely difficult. In Japan, China, Australia and Switzerland, tip nothing. And no amount of cash at the front desk produces an upgrade, because the person accepting it usually cannot give you one.
Tipping is the part of a luxury stay people quietly worry about, partly because the numbers are never published and partly because the stakes feel higher at a hotel charging US$900 a night than at one charging US$200. The honest position is that the amounts are smaller than most guests fear, the timing matters far more than the size, and in a meaningful number of countries the correct amount is nothing at all.
The numbers, in one place
For a US property, the working figures are these. Housekeeping: US$5 to US$10 a night at a luxury hotel, more where there is evening turndown or where you are occupying multiple rooms. Bellman or porter: US$5 for the first bag and US$2 to US$5 for each one after, at the upper end if anything is heavy or awkward. Valet: US$2 to US$5 each time the car is brought to you, not on the way in. Room service: 15 to 20 percent, unless a service charge has already been added, in which case a few dollars in cash is courteous rather than required. Concierge: US$10 to US$20 for a reservation that was genuinely hard to secure, US$25 to US$50 for an itinerary they built out over several days. Butler, where one is assigned: US$10 to US$20 a day for light assistance, US$20 and upward for genuinely personalised service, or roughly 5 percent of the room rate across the stay.
Those are ranges, not rules, and the top of each range is for a property where the service is exceptional rather than merely competent.
Housekeeping is the one most people get wrong
The common approach, leaving a lump sum on the last morning, sends the whole amount to whoever happened to service the room last. Attendants rotate, and on a five-night stay three or four different people will have cleaned your room. Leave the tip daily instead, in cash, and make it unambiguous: an envelope, or a note on the pad. Housekeeping staff at good hotels are trained not to touch money that has not been clearly left for them, which is exactly why cash on a nightstand often goes untouched for the entire stay.
A service charge is not the same as a tip
A line on the folio reading "service charge" is a charge levied by the hotel. Whether it reaches the staff, and in what proportion, varies by property and by jurisdiction. In much of Europe and Asia it genuinely is distributed; elsewhere it can function as revenue. The practical move is to ask at check-in whether the service charge is distributed to staff. If the answer is yes, your additional tipping can be modest. If the answer is vague, tip as though the line were not there.
The concierge: pay for outcomes, not attempts
Tip the concierge after the thing has worked, not before. A tip handed over with the request reads as an attempt to buy an outcome the concierge may not be able to deliver, and it puts them in an awkward position for the rest of your stay. When the table you could not get materialises, or the closed exhibition opens for an hour, that is the moment. If nothing came of it, nothing is owed, and a good concierge will not expect otherwise.
Where you should not tip at all
Japan is the clearest case: do not tip. It is not a matter of amount but of category, and a cash tip creates work and mild embarrassment for the person receiving it. China and Australia are similar, though for different reasons. Switzerland includes service by law and does not expect more. In France, Italy, Spain and Germany, one to two euros a bag covers the porter, and restaurant service is already included through service compris or the Italian coperto. The United Arab Emirates sits closer to the US model: roughly AED 5 to 10 a bag and AED 10 to 20 a day for housekeeping.
Then there are the brands. Aman and Six Senses, among others, operate an explicit no-tipping policy, and their staff are instructed to decline. Many all-inclusive resorts say gratuities are included and mean it. When a property tells you tipping is not expected, take it at face value rather than insisting.
What a tip does not buy
The persistent myth is the folded note at check-in that produces a suite. It does not work, and the reason is structural rather than moral. Room assignment is largely settled before you walk through the door, by the front office working from the day's unsold inventory, the notes attached to your reservation and the rate code you booked. Our founder spent just over a year at Four Seasons across Singapore, Hong Kong and Tokyo, and the pattern was consistent: by the time a guest is standing at the desk, the better rooms are either already allocated or already sold, and the agent in front of them frequently has no authority to move them anyway.
What actually moves a room assignment is a reservation flagged through a preferred-partner program days in advance, an occasion noted on the booking early enough for someone to act on it, and arriving late enough in the day that the inventory picture is clear. All three are things that happen before you arrive. None of them cost anything at the desk.
Our position
Budget roughly 2 percent of your room rate for gratuities in the United States and nothing whatsoever in Japan. Carry small bills, because the correct tip you cannot break a note for becomes no tip at all. Tip daily, tip in cash, and tip after the service rather than before it. And keep the perks that come with a preferred-partner booking mentally separate: the upgrade, the breakfast and the credit are funded by the hotel as part of a commercial program, and no gratuity is expected or appropriate for any of them.
