How Much Cash to Bring on Vacation

Start with days, people and a daily cash rate

A cash budget is three numbers multiplied together, plus a buffer. The three are trip length in days, the number of people, and what one person spends in a day. Multiply them and you have the trip's total spending. Then decide what share of that spending will be cash rather than card.

trip spending = days x travelers x daily spend per person
cash for spending = trip spending x cash share

The daily number is the one people guess wrong. It should cover food, local transport, tips, entry fees and small purchases, not the hotel, which is almost always paid by card before you arrive. A domestic road trip at $50 a person a day and a week in a big city at $120 a person a day are both normal, and the calculator handles either.

The cash share is a judgment call. Ten to twenty percent suits a country where cards work everywhere. Forty to sixty percent suits a destination where markets, taxis and small cafes still run on paper money. Above seventy percent you are carrying more cash than most travel insurers and card protections would advise.

Worked example: 7 days, 2 travelers, $60 a day

Two people, seven days, $60 a person a day, and 40% of spending paid in cash. Every step below is what the calculator on this page does with the same inputs.

• Trip spending: 7 x 2 x 60 = $840
• Cash for daily spending: 840 x 0.40 = $336
• Card spending: 840 - 336 = $504
• One reserve day of cash: 2 x 60 x 0.40 = $48
• Cash to bring: 336 + 48 = $384
• Withdrawals at $200 each: 384 ÷ 200 = 1.92, so 2 withdrawals
• ATM fees: 2 x $3 = $6, for a total cash outlay of $390

The $6 in fees is worth a thought. Two withdrawals cost $6, while five small withdrawals at the same fee would cost $15, so pulling a larger amount less often is cheaper if the machine allows it. The trade-off is carrying more cash at once.

How much of the trip should be cash

Cards win on protection and records. Cash wins on acceptance, tips and small vendors. A split that matches how you pay is better than a single percentage picked in advance.

Keep the card for anything with a deposit, a damage waiver or a refund policy. A card dispute can recover money; cash cannot. Keep cash for anything where the seller, not the bank, decides whether you can pay.

One more split worth making: carry the daily cash in one place and the reserve somewhere else. A wallet lost with $200 is a bad afternoon. A wallet lost with the whole $384 and no backup is a ruined trip.

Daily cash by destination type

These are planning ranges, not official figures. They cover one person for one day of food, local transport, tips and small entries, with the hotel paid separately.

A resort where everything goes on a room key needs less cash than a mountain town with one machine that runs out on weekends. The last row is the case that catches people: when the nearest ATM is an hour away, the cash share should be high even if the destination is cheap.

Keep the emergency reserve separate

The reserve is not spending money. It is the amount that covers a dead card, a lost wallet or a shop that takes only cash when you did not plan for it. One day of cash for the whole party is a reasonable floor, and two days is safer on a longer trip.

reserve = travelers x daily spend x cash share x reserve days

For the example trip that is 2 x 60 x 0.40 x 1 = $48. Two reserve days would be 2 x 60 x 0.40 x 2 = $96, which pushes the cash total from $384 to $432. On a two week trip the same two reserve days are worth more, because there are more chances for something to go wrong.

Store the reserve apart from the daily cash: a money belt, a hotel safe, or a second wallet in a different bag. The point of a reserve is that it survives the loss of the first pile, and cash in the same pocket as the spending money is not a reserve.

ATM fees and withdrawal math

Every withdrawal can carry two charges: the fee from the machine's operator and the fee from your own bank. A $3 machine fee is common in the U.S., and a foreign ATM can add a currency conversion markup on top. That is why the number of withdrawals matters as much as the amount.

withdrawals = cash needed ÷ withdrawal amount, rounded up
fees = withdrawals x fee per withdrawal

For $384 at $200 a time, 384 ÷ 200 = 1.92, so you make 2 withdrawals. At $3 each the fees are $6, and the true cost of the cash is $390. Take the same $384 out in four $100 withdrawals and the fees double to $12. Take it in one $400 withdrawal and you pay $3, but only if the machine dispenses that much, which many do not.

A debit card is usually cheaper than a credit card for cash, because a credit card cash advance starts charging interest the day you take the money. Check the daily withdrawal limit on your card before you leave; $300 to $500 a day is typical, and a limit below what you need will force extra withdrawals and extra fees.

What the rules say about carrying cash

Two official rules matter for a U.S. traveler. The first is reporting. U.S. Customs and Border Protection requires travelers entering or leaving the country with more than $10,000 in currency or monetary instruments to file a report, FinCEN 105, as described on its traveler guidance pages. Carrying the money is legal; failing to report it is not, and the report is a form, not a tax.

The second is card protection. The FDIC explains on its consumer deposit account page that if you report a lost or stolen debit card within two business days, your losses are capped at $50. Wait longer and the cap rises, which is the strongest argument for checking your account daily while traveling.

Before a trip, the State Department's travel advisories page is worth two minutes, because an advisory can change how much cash you want on hand and where you want to keep it. None of this is financial advice. It is the paperwork and the safety net, and both are cheap to check before you fly.

Cash target by trip length

Same assumptions as the worked example: two travelers, $60 a person a day, 40% cash, one reserve day. Only the trip length changes.

The reserve stays flat because it is one day of cash, not a percentage of the trip. That is deliberate: a longer trip needs the same one day of protection per incident, though more incidents become possible. If you want the reserve to scale, set reserve days to 2 on trips over ten days.

A 14 day trip at these numbers needs $720 in cash, which is more than many people want to carry at once. The practical answer is to bring half and plan one mid-trip withdrawal, then let the fee math decide whether that withdrawal is worth $3 or $6. The calculator's withdrawal row shows the split, and the reserve row tells you the floor you should never drop below.
