How to use
- 01
Enter how many people are travelling and how many nights away. Both drive almost everything else — and note the day count: a trip of seven nights is eight days of eating, which is the off-by-one that makes hand-built trip budgets come in short.
- 02
Enter airfare per person twice — once domestic, once international for the same itinerary. Both totals are computed and shown side by side, so you can price two destinations without redoing the ground costs.
- 03
Enter lodging per night for the WHOLE party, because rooms are booked rather than people, then food and local transport per person per day, because those are not.
- 04
Add activities and everything else as whole-trip figures — tours, tickets, travel insurance, visas, bags, parking, a sitter at home — and set a contingency for the day that goes wrong.
- 05
Enter what is already saved and the months until departure, and the page gives you the monthly amount that has the trip paid for before you go. The schedule reruns the same party across a range of trip lengths, which is usually the lever with more give in it than the destination.
Formula
Days on the ground = nights + 1. Ground cost = lodging per night × nights + (food per person per day + local transport per person per day) × travellers × days + activities + everything else. Domestic total = (ground + domestic airfare × travellers) × (1 + contingency). International total = (ground + international airfare × travellers) × (1 + contingency). Per person = total ÷ travellers. Per person per day = total ÷ (travellers × days). Still to save = total − saved. Monthly needed = that gap ÷ months until departure.
Example
Four travellers, seven nights, $320 a head domestic against $1,150 international, $220 a night of lodging for the party, $55 a head a day for food, $20 a head a day of local transport, $600 of activities, $350 of everything else, a 10% contingency, $1,500 saved and eight months to go. Seven nights is eight days, so food is $55 × 4 × 8 = $1,760 and local transport $640; lodging is $1,540. Ground costs come to $4,890. Flying domestic the trip is $6,787 — $1,697 a person, $212 per person per day; flying international the identical itinerary is $10,439, a difference of $3,652 that is entirely airfare. With $1,500 already saved, $5,287 is left, or $661 a month across the eight months. The schedule shows where the give is: the same party for five nights is $5,643 domestic and for three nights $4,499, so two nights off the trip is worth $1,144 — more than a third of the gap between flying domestic and international.
Definitions
- Ground cost
- Everything that is not airfare: lodging, food, local transport, activities and extras. It scales with nights and party size, which is why trip length is usually the lever with the most give.
- Days on the ground
- Nights plus one. You eat on the day you arrive and the day you leave, and budgets built on nights are short by exactly one day of every per-day cost.
- Per person per day
- The comparable unit across trips of different lengths and party sizes — and the only figure on this page worth carrying from one trip to the next.
- Unit confusion
- The failure mode of every published vacation average: per trip, per week, per household, planned budget against actual spend. Any figure quoted without its unit is unusable.
Good to know
A trip is almost entirely money you were not going to spend anyway
The most common way a vacation turns out to cost more than planned has nothing to do with the destination. It is the quiet assumption that the trip replaces a normal week rather than adding one. It does not. Rent or the mortgage runs while you are away, and so do the car payment, the insurance, the utilities, the phone bill, the gym membership and every subscription. None of them pause, and none of them can be netted off against the trip. The only line that genuinely substitutes is food at home, and it substitutes weakly: the fridge was stocked before you left, the standing grocery order arrives anyway, and what replaces it is bought at the price of eating out rather than the price of eating in — so the swap costs more than it saves on almost any trip. Several household costs actually rise while you are gone. Boarding a dog or a cat, a sitter for the house, a week of airport parking, somebody to water the plants: pure additions that exist because of the trip and only during it, which is exactly what the everything-else field is for. Then there is the largest hidden cost of all, and it depends entirely on how you are paid. A salaried employee taking accrued leave loses no income, and for them the trip costs what the trip costs. An hourly worker, a contractor or anyone self-employed is buying the time as well as the holiday, and a week of foregone earnings is frequently the same order of magnitude as the entire budget on this page. It belongs in the total, because the household feels it in the same month. The practical upshot is that a vacation is close to pure incremental spending laid on top of an ordinary month, which is why it has to be funded from money set aside for it and not from money the household imagines it would have spent regardless.
Airfare is the visible line, and only sometimes the biggest one
Airfare behaves unlike every other cost on a trip: it is fixed per person and completely indifferent to how long you stay. Everything on the ground is the opposite — lodging scales with nights, food and local transport with people and days. So airfare's share of a trip is not really a property of the destination, it is a property of the length, and it falls as the trip gets longer. The arithmetic is easy enough to do in your head. A fare of A per person is overtaken by food alone once the days on the ground times the daily food figure exceed A: at $60 a head a day, a $320 domestic fare is passed on the sixth day and never leads again. Add lodging and local transport and the crossover arrives sooner. This is why the flat claim that the flight is not the biggest cost is only half right, and why this page computes both versions of the trip. Domestically, on any stay longer than a long weekend, airfare is routinely beaten by food away from home and often by lodging as well. Internationally the fare is several times larger, still applied per person, and it frequently is the single largest line on an identical itinerary. Both are priced off one set of ground costs precisely so you do not have to guess which case you are in. What keeps people convinced the flight dominates is salience rather than size. It is bought first, months ahead, in one transaction, with a number attached and a screenful of alternatives to compare against. Ground spending arrives as fifty small transactions during the trip and is never seen as a single figure until the statement lands. Two hours spent hunting a $40 fare saving while $80 a day of ground spending goes unexamined is the standard misallocation of attention on this subject, and the schedule of trip lengths is the fastest way to see it.
The lines with no sticker price: ground transport, fees and food
Three costs are systematically underestimated, and they are underestimated for the same reason: none of them is quoted as a single number before the trip. Ground transport is the field most often left at zero. A rental car's advertised daily rate is not what it costs — airport concession recovery fees, vehicle licensing fees, local surcharges, a collision damage waiver if your own policy or credit card does not extend, the tank you did not return full, and hotel parking billed per night, which is a lodging charge hiding inside the transport line. In a city, two airport transfers with luggage plus daily movement around town is real money that appears in no plan and on every statement. Lodging has the same problem one level up: the nightly rate in a search result is rarely the nightly rate charged. Resort and destination fees, cleaning fees on short-term rentals, occupancy taxes that differ by city, and a service fee added at checkout can add a fifth to a booking that looked settled. The figure to enter is the checkout total divided by the nights, not the number the search result advertised. Food away from home is the third and the most reliable overrun, because it is bought in the smallest pieces with the least deliberation. Everybody eats every meal out, including the children who now order from a menu, and the daily figure that felt generous when you typed it turns out to have assumed one coffee rather than three and no drinks with dinner. Set it honestly rather than aspirationally. The per-person-per-day food number is the single most useful thing you will learn from one trip and carry to the next, and the only way to learn it is to compare what you budgeted against what the cards actually say when you get home. Together these three are why a properly composed ground total is larger than the one people carry in their heads, and why the contingency line exists at all.
Domestic against international, beyond the fare
Holding the itinerary fixed and swapping only the airfare is a deliberate control. It isolates one variable so you can see what the flight is worth, and like every control it is artificial: real international trips differ from domestic ones on far more than the flight. Start with the costs that exist on only one side. A passport, or its renewal, for everyone travelling — including children, whose passports expire faster than adults do. Visas or electronic entry authorisations, which more countries now charge for. Vaccinations or antimalarials for some destinations. A foreign transaction fee on every card purchase unless the card waives it. The currency conversion the payment terminal offers you at the till, which is always worse than declining it. Withdrawal charges at foreign cash machines. Roaming, or a local data plan, for every phone. Individually small, collectively a real slice of a short trip, and all of it belongs in the everything-else field. Then health cover, which is the one that can be genuinely large. Most domestic US health plans provide little or nothing outside the country, and Medicare generally does not travel at all. Ordinary care abroad is often cheaper than it is at home; the exception is medical evacuation, which is the only travel cost that regularly reaches five figures and is the real reason travel medical policies exist. Finally, the two trips are usually not the same length, and that is not an accident. A large fixed fare and two days lost to flying push international trips longer, because the fare amortises — the crossover from the airfare arithmetic operating as a decision rather than an observation. So the honest comparison is rarely seven nights against seven nights; it is a domestic week against an international fortnight, and the schedule of trip lengths is where you build it. Worth allowing for as well: on a short international trip the arrival day and the departure day are frequently not usable days at all, so the days you actually get are fewer than the days you paid for.
Frequently asked questions
What is the average cost of a vacation per person?
There isn't a verifiable one, and this page will not invent it. No government agency and no survey publishes a US average cost per person per trip, and the figures in circulation are not competing estimates of one quantity — they are different units wearing one label. $581 domestic against $3,251 international is per trip, from an analysis whose underlying survey year could not be confirmed. $2,400 against $4,500 is an aggregator figure with no stated source. $7,249 comes from travel-insurance quote data, and insured trips skew long and expensive. $2,275 is per week. Deloitte's $3,471 is a planned budget per household, not actual spend per person. Averaging them would manufacture a number no source supports.
So what should I compare my trip against?
Your own last trip, and the schedule on this page. The only government anchor with a firm data year is the BLS Consumer Expenditure Survey, whose 2024 figures were released in December 2025 and which reports household spending on lodging away from home and on food away from home on trips. Its unit is annual spending per household — useful for asking whether your year of travel is normal, and useless for asking whether this trip is.
Why is lodging per night but food per person per day?
Because that is how each is actually bought. A room costs what it costs whether two people or four are in it, so lodging scales with nights and not with the party. Food and local transport scale with both. Getting these two conventions the wrong way round is the fastest way to a budget that is out by a third, and it is why the fields say which is which rather than leaving it to be inferred.
Why does the day count differ from the night count?
Because you eat on the day you arrive and the day you leave. A seven-night trip is eight days on the ground, so a four-person party at $55 a head a day is $220 short if the budget uses nights. The page adds the extra day automatically and the insight says what it is worth on your numbers.
How do I compare a domestic and an international trip?
Enter both airfares and the page prices both totals off one set of ground costs. Ground costs are usually where the honest comparison lives: airfare is the visible difference, but a fortnight of lodging and food at destination prices frequently swamps it. The schedule runs both columns across a range of trip lengths so you can see where the two cross.
Should I include travel insurance?
In the everything-else field, yes — along with visas, bag fees, airport parking and a sitter at home. These are the lines that are individually small and collectively a real fraction of a short trip, and they are exactly what gets left out of a budget built from airfare and hotel alone.
How far ahead should I start saving?
Far enough that the trip is paid for before you go rather than after, which the months-to-departure field turns into a monthly number. The order the money is actually needed in is not level — airfare and lodging deposits land at booking, months out, while food and local spending happen on the trip — so a short runway is disproportionately front-loaded.
