There's no single right number, but there is a right method. Modern travel runs mostly on cards, so the question isn't "how much cash do I bring?" — it's "what's my card setup, and how much cash backs it up?" Get that balance right and you'll glide through your trip without overstuffing your wallet or running short in a cash-only corner. Here's how to estimate your number, carry it safely, and top up as you go. Card and cash norms vary by destination — for the on-the-ground reality of where you're headed, ask Mike in the app.
Make cards your default, cash your buffer
The cleanest setup for almost any destination is a card you lead with for most spending, plus a modest cash buffer for the places plastic doesn't reach. You don't need to carry your whole budget in notes — most of it can stay safely on your card and be drawn down as needed. Think of cash as a backup layer, not the main event.
- Lead with a card; let cash be the backup layer
- Most of your budget stays safely on the card, not in your pocket
- A small cash buffer covers markets, tips and rural gaps
Estimate by days and travel style
Start with a rough daily spend for your style of travel — a backpacker, a comfortable mid-range traveler and a luxury traveler land in very different places. Multiply by your number of days, add a cushion for one-off costs like a big activity or a nice meal out, and you have a working budget. This is the figure your card carries; only a slice of it needs to be cash.
- Daily spend x days + a cushion = your working budget
- Backpacker, mid-range and luxury differ widely per day
- Add a one-off cushion for activities, splurges and surprises
Don't carry too much cash at once
Walking around with weeks of spending in notes is the one habit that turns a lost wallet into a real problem. Carry a comfortable amount for the next day or two, keep the rest as a stash or simply on your card, and refill little and often. Less cash on you means a pickpocket or a misplaced bag is an annoyance, not a disaster.
- Keep only a day or two of cash on you at a time
- A lost wallet should be an annoyance, not a catastrophe
- Refill little and often rather than carrying a lump
Keep an emergency stash, separate
Tuck away a small emergency reserve — some cash plus a backup card — somewhere apart from your everyday wallet. A hotel safe, a separate pocket in your bag, a different compartment: anywhere that won't be lost in the same moment as your main wallet. If your primary card is declined or your wallet vanishes, this is what keeps you moving until you sort it out.
- Stash a little cash plus a backup card separately
- Keep it apart from your everyday wallet, not beside it
- It's your lifeline if the main wallet is lost or a card fails
Plan to top up locally, not all upfront
You rarely need to arrive with a thick stack of foreign notes. Withdraw local cash from bank ATMs as you go, in amounts that suit how cash-reliant the place is. Topping up locally gives you a fairer rate than changing a big lump at home or at an airport kiosk, and it means you only ever hold what you actually need.
- Top up from bank ATMs along the way, not all at once
- Local withdrawals usually beat home or airport exchange rates
- Hold only what you need; refill as the trip goes on
Adjust for how cashless your destination is
Some destinations are nearly cashless and a small buffer goes a long way; others run heavily on cash and small change, so you'll want more in hand. Knowing which kind of place you're visiting is what turns a generic budget into the right number for you. When in doubt, ask Mike for how card- or cash-reliant your destination really is.
- Cashless destinations need only a thin cash buffer
- Cash-first places call for more notes and small change
- Ask Mike how card- or cash-reliant your destination is
Key takeaways
- Lead with a card and let a modest cash buffer back it up — most of your budget stays on the card.
- Estimate with daily spend for your travel style x days, plus a cushion for one-off costs.
- Don't carry too much cash at once; keep a day or two on you and refill little and often.
- Keep a separate emergency stash of cash plus a backup card, and top up locally as you go.
The right amount to bring isn't a number you guess — it's a setup you build: a card you lead with, a modest cash buffer for the gaps, a separate emergency stash, and a plan to top up locally. Size it by your days and your style, keep little cash on you at any one time, and you'll have exactly what you need without ever carrying a fortune you could lose.
