Build U.S. gratuities into your daily budget from the first day: 20% at restaurants and 15–20% for taxis and tour guides. A week of restaurant meals adds that percentage to every check, so the total is easy to underestimate. To see the real cost, list each planned restaurant meal and multiply the average check by 0.20. Add a separate line for taxis and guided tours at 15–20%. A $50 restaurant meal typically costs $60 with a 20% tip; a $100 guided tour costs $115–120 with a 15–20% tip. In Japan and China, leave nothing; a tip there is more likely to offend than to reward, and the gesture may be met with confusion rather than thanks.

Europe sits between those extremes. France includes a service charge by law, so extra tipping is unnecessary, though rounding up is appreciated. Italy's coperto, a cover charge, replaces tips. A service charge is a percentage added for staff; a cover charge is a flat fee for the table. Greece often adds a service fee to restaurant bills, making tips unnecessary but a few extra euros welcome. Germany includes a service charge, but adding 5–10% or rounding up is common. Look for the line item before the total. If no service charge or cover charge is listed and you are unsure, add 10% or round the bill up to the nearest 5 or 10 euros. A €47 bill becomes €50; a €52 bill becomes €55. In France, a €38 meal rounded up to €40; in Germany, a €22 meal rounded up to €25.

Latin America has no single rule. In Mexico, tip in pesos, never U.S. dollars, to avoid exchange-rate losses and ensure staff actually receive the tip. Norms vary across the region, so treat any single rule as a starting point. Ask your hotel concierge or local host what is standard before you go out for the evening.

Check the bill for a service charge or cover charge before adding anything; missing either line leads to double-tipping. For hotel housekeeping, plan on $3–10 per day, left at the end of each day. Leave cash daily rather than a lump sum at the end of your stay, so the person who cleaned that day receives it. Check whether a resort fee already covers gratuities before you leave cash daily; the fee is usually listed on your booking confirmation under 'resort fee' or 'facility fee.'

Carry small bills for tipping, and use local currency. In Turkey, leave cash on the table because card tips rarely reach staff. In Greece, only about half of credit card machines can handle tips, so cash is essential. Small denominations make rounding up easy and avoid the awkwardness of asking for change. Round up instead of calculating percentages when service is adequate. This keeps tips modest without seeming stingy. On card machines that prompt for a tip, choose 'other' and enter a round amount in local currency; if the machine does not allow that, have cash ready. Factor gratuities into your trip budget before you leave, the same way you would plan for other daily costs in your budget travel plan.

If you can afford a service, you can afford the gratuity.

When in doubt in a tipping culture and no service charge is listed, always round up. In Japan and China, the rule remains leave nothing. Getting it wrong can range from mildly embarrassing to genuinely insulting, so a few minutes of research pays off. Treat published figures as illustrative and confirm current local practice; use recent sources because tipping customs change over time. For a first visit, search the country name plus 'tipping' on official tourism board sites. Many first-time visitors over-tip out of habit or under-tip out of uncertainty; both are avoidable with basic research.
