BUDGET
How to budget a trip without guesswork
A budget is nights times lodging plus calendar days times daily spend, then flights and a buffer. Count the days first, then use destination prices — not habits from home.
Quick answers
How do I budget a trip?
Lodging by nights, food, transit and tickets by calendar days, plus transport there and back and a 10–20% buffer. Count nights and days separately.
How much should I allow per day?
Split lodging, food, local transit and data at mid-range local prices. An East Asia short break and two weeks in Europe are different bands. Recalibrate with local cost-of-living data, not prices from home.
Why keep a buffer?
Exchange rates, a changed plan, a clinic and overweight bags break a precise estimate. 10–20% usually absorbs them. You do not need to minimise every line.
Why do cheap flights still blow the budget?
The fare often excludes bags, seats and airport transfers. Compare landed cost. A connection overnight can eat the fare gap.
01A budget is a stack#
Split four blocks: transport there and back, lodging, daily spend (food, local transit, tickets) and a buffer. Get the order of magnitude first. Pricing a foreign city with home-city menus is the usual underestimate.
Lodging is per night; meals and tickets are per calendar day. Three hotel nights often span four calendar days. Mixing the units drops a day’s food or adds a phantom night. This site’s trip-days tool separates nights from days.
02Four daily lines#
The table is a planning range, not a quote. The East Asia short break assumes a mid-range room and eating out without tasting menus. Two weeks in Europe assumes mid-range hotels and some paid sights. City centres and peak dates go up; shoulder-season suburbs go down. Figures age — recalibrate with local cost-of-living data.
Keep data on its own row so it is not lost in “misc.” An eSIM is usually one prepaid amount; spreading it per day makes it comparable with a daily roaming pass.
| Line | East Asia short break (~4–5 days) | Two weeks in Europe (~14 days) | Notes |
|---|---|---|---|
| Lodging (per night) | Mid-range about $50–120 / night | Mid-range about $80–180 / night | Centres and weekends cost more |
| Food | $25–50 / day | $40–80 / day | Supermarket meals cut this sharply |
| Local transit + short tickets | $8–20 / day | $15–35 / day | A day pass can beat singles |
| Data (spread per day) | eSIM about $1–4 / day | Multi-country eSIM about $2–6 / day | Do not compare day-roaming to an unlimited pack |
03Flights and the fees inside the fare#
Budget fares often exclude bags and seats. Add baggage, airport transfers and a possible overnight into “landed cost.” A cheaper connection can lose to one airport meal and a transit hotel.
Example: $400 return + $60 bags both ways + $40 airport transfers is $500 in the transport block, not $400. Add five nights at $90 and six calendar days at $60 daily: about $500 + $450 + $360 = $1,310, then a 15% buffer.
04Buffer and currency#
Keep 10–20% on top for FX, a changed plan and a clinic visit. Watch foreign transaction fees and DCC on cards; compare the mid-market rate with the desk rate when you change cash. A small percentage on hotels and tickets outweighs skipping a lunch.
Hold the buffer on a second card or account so a busy primary card cannot spend it. A budget is a floor, not a contest to minimise every line.
05Do not mix nights, calendar days and headcount#
Three hotel nights are usually four calendar days: Friday check-in, Monday check-out. Multiply lodging by nights and meals or tickets by calendar days. For a shared room, divide the room, keep meals per person, then split shared tickets such as airport transfers.
Example: two people, five nights, six calendar days. A $90 room is $450, or $225 each for lodging; $40 food × 6 = $240 each; $15 local transit × 6 = $90. Baseline about $555 each before the flight share and buffer. A one-line “$550 for five days” hides the mix-up.
06Tickets, city passes and days you barely spend#
The four daily lines hide lumpy costs. A €22 museum, a €45 airport train, or a day tour can equal two or three days of food in a single tap. List those named tickets separately, then spread only the ones that actually happen every day. A 48- or 72-hour city pass is a save when you would have paid for three sights plus unlimited metro; it is a loss if the plan is two museums and a lot of walking. Check whether the pass needs a photo, a named holder, or activation at a machine that is closed on Sunday morning — a pass you cannot start is not a discount. The same applies to rail: a regional day ticket can beat three singles, but only on the days you actually ride. Count only tickets you have already decided to buy; a maybe-list inflates the daily rate.
A rest day still costs the room. Cutting tickets and switching to supermarket food can halve the daily line; the night does not disappear. Write the stack as nights × lodging + calendar days × a realistic floor for food and local transit + a short list of named tickets + transport there and back + 10–20%. Then mark which calendar days are “pass days” versus “laundry and groceries.” Fourteen days in Europe with four expensive sight days and ten cheap days is not fourteen times the expensive rate. If two people share a pass that is priced per person, do not split it in the sheet. If a city pass is sold per calendar day rather than per 24-hour block, start it on the morning you will actually use the sights, not on the evening you arrive. This site’s trip-days tool separates nights from calendar days; it does not price tickets.
07Common mistakes#
Costing meals by nights, rooms by calendar days, ignoring bags, pricing restaurants from a home menu, and skipping a buffer. Another is the cheapest flight plus daily taxis, which returns you to a dearer daily rate.
With several people, write down what is shared (room, car) and what is per head (food, tickets) before you divide. Otherwise “per person” looks falsely low.
08Recalculate before you pay#
Lock nights versus calendar days; fill the four daily lines with local prices; fold hidden flight fees into transport; add the buffer; then set a cap that does not starve the trip.

How many days is 3 nights? What “3 days 2 nights” means
Hotel “3 nights” and a tour’s “3 days 2 nights” are not the same unit. Split nights from calendar days before you match a leave form or the morning you fly home.
Paying abroad: cards, cash and the conversion fee trap
Spending abroad usually has two costs: your issuer’s foreign transaction fee, and the spread charged by a terminal or exchange desk. Separate them before you choose which card to pack and how much cash to carry.
Paying abroad: separate DCC markup from your card's foreign fee
A familiar home-currency amount on a terminal is not a discount. Decline merchant conversion first, then calculate the fees in your own card agreement.
