Tip Calculator

Either is acceptable, but the traditional approach is to tip on the pre-tax subtotal. The reasoning is that sales tax is collected for the government rather than earned by the restaurant, so the tip reflects only the value of the food and service. In practice, many people tip on the post-tax total simply because it's the number printed at the bottom of the receipt, and servers won't object to the slightly larger amount. The gap between the two is usually minor. On a $100 meal with 8% tax, an 18% tip comes to $18 on the pre-tax subtotal versus $19.44 on the $108 post-tax total — a difference of just $1.44. Pick whichever is easier; consistency matters more than the cents.

Tipping on takeout is optional, and a smaller amount than dine-in is generally considered fine. Because there's no table service to reward, takeout traditionally carried no tipping expectation at all. In recent years, though, point-of-sale screens that prompt for a tip have made small gratuities more common, and many people now leave around 10% or a flat $2–3 on a modest order. It's a reasonable gesture when staff goes out of their way — packing a large or complicated order, handling special requests, or bringing food out to your car for curbside pickup. Large catering or party orders that involve real preparation and coordination are closer to full service, so 15–20% is appropriate there. For a simple grab-and-go coffee or bag, no tip is perfectly acceptable.

In the US, leaving at least around 10% is customary even when service falls short. The reason is that servers typically depend on tips for most of their income, and many problems that feel like poor service — slow food, missing items, a crowded section — actually stem from the kitchen or short staffing rather than your server's effort. A reduced tip in the 10–12% range signals dissatisfaction while still acknowledging the work involved. If the experience was genuinely unacceptable, the more effective response is to speak with a manager calmly and explain what went wrong, since a zero tip rarely communicates the specific issue and may simply read as an oversight. That feedback also gives the restaurant a real chance to make it right.

No, you generally don't need to tip on top of an automatic gratuity — it already serves as the tip. Restaurants commonly add an automatic gratuity, often around 18%, for large parties (frequently six or more guests) to make sure servers are fairly paid for tables that take more time and effort. Once that charge appears on your bill, the standard tip is considered covered, and you're under no obligation to add more. You're always free to leave a little extra in cash or on the card if the service was exceptional, but it's entirely optional. The key step is to read your receipt carefully before adding anything, because it's easy to tip a second time by reflex and end up paying gratuity twice.

Tipping customs vary dramatically from country to country, and the US norm of 15–20% is not universal. In Japan and South Korea, tipping is often unnecessary and can even be perceived as awkward or impolite, since good service is considered standard. Across much of Europe a service charge may already be included in the bill, so locals tend to simply round up or leave a small amount for good service rather than a large percentage. Australia and New Zealand have a relatively light tipping culture, with tips treated as an optional bonus. Canada generally follows patterns similar to the US. Because expectations differ so much, it's worth checking the local norms for your specific destination before you travel rather than assuming one rule applies everywhere.
