How to Tip at a Restaurant: Percentages, Splitting and Card Tips
Introduction
Tipping at a restaurant is a small calculation wrapped in a large social question: how much, on what amount, and what happens when the bill is already carrying a charge you did not ask for? Get the maths right and the etiquette mostly follows, because most tipping awkwardness is really arithmetic anxiety — not knowing the number before the card machine arrives.
This guide gives you the numbers first and the customs second: the standard percentages for sit-down, bar, buffet and takeout service, whether to tip on the pre-tax or post-tax total, how to split fairly between people who ordered differently, what automatic gratuity and service charges actually mean, and how card tips, tip pools and the law fit together. The free Tip Calculator on this site does the arithmetic; this guide explains the decisions behind it.
The standard percentages, by type of service
For sit-down table service in the United States, the everyday standard for good service is 18 to 20 percent of the pre-tax bill, with 15 percent as a floor for service that was merely adequate and 22 to 25 percent for service that genuinely stood out. That range has drifted upward over the past two decades from the older 15 percent standard, and in major cities 20 percent is now the most common single choice. Outside the United States the picture changes completely: many European restaurants include service in the price or add a discretionary charge, and a small additional tip, if any, is a courtesy rather than an expectation.
| Situation | Usual tip | Notes |
|---|---|---|
| Sit-down, good service | 18-20% of pre-tax bill | The everyday standard in the US |
| Sit-down, exceptional service | 20-25% | For service that went well beyond the basics |
| Sit-down, poor service | 10-15% | Still a tip unless service was truly unacceptable; raise problems with staff first |
| Fine dining | 20% or more | Sommelier service is sometimes tipped separately |
| Buffet | Around 10% | Staff clear plates and refill drinks but do not take orders |
| Bar, per drink | $1-2 per drink | Or 20% on a running tab |
| Counter or fast-casual | 10-15% or $1-2 | Optional; increasingly expected where food is brought to the table |
| Takeout or pickup | Optional, around 10% | A courtesy for large or complex orders |
| Food delivery | 15-20%, minimum $3-5 | More in bad weather or for large orders |
| Large party (6 or more) | Check for auto-gratuity first | Often 18-20% already added |
The calculation itself: three ways to get the number
Step 1: Start from the pre-tax subtotal
Find the subtotal before sales tax. Tipping on the pre-tax amount is the traditional basis, because tax is money collected for the government, not a service you received. On a 50 dollar bill with 8 percent tax, the difference between tipping on the subtotal and on the total is small — at 20 percent it is about 80 cents — but the habit matters on large bills, and it is the figure most guides quote.
Step 2: Apply your percentage
Tip equals subtotal times percentage divided by 100. A 60 dollar subtotal at 20 percent gives a 12 dollar tip and a 72 dollar total before tax. At 18 percent the same bill gives 10.80 dollars. The Tip Calculator on this site takes the bill, the percentage and the number of people splitting, and returns the tip, the total and the per-person share in one step.
Step 3: Round sensibly, or split fairly
Rounding up to a whole dollar is normal and generous in small amounts: a 11.40 dollar tip on a 57 dollar bill becomes 12 dollars without a second thought. When splitting, divide the total including tip by the number of people for an even split, or calculate each person's share from what they ordered when orders differ sharply — the fairest method, and the one that prevents the perennial argument about who had the steak.
Pre-tax or post-tax: does it actually matter
Tipping on the post-tax total is widespread and slightly more generous, because the tax inflates the base by the tax rate — typically 5 to 10 percent of the bill, so the tip rises by the same proportion. On an everyday meal the difference is under a dollar; on a large group dinner it can be several dollars. Neither choice is wrong, and servers do not audit your base: what matters is tipping in the right range on a sensible base, not optimising the last few cents. If you want a rule, tip on the pre-tax subtotal when the bill shows it clearly, and on the total when it does not — consistency beats precision here.
Splitting the bill without the argument
An even split is fair when everyone ordered similarly and shared starters; it is the default for friends and it keeps the evening pleasant. When one person ordered a starter, a main, dessert and wine while another had soup and water, an even split quietly overcharges the light eater, and the honest method is to split by what each person ordered: each person's subtotal plus their share of shared items, with tip calculated on their own subtotal at the agreed percentage. The Tip Calculator handles the even-split case instantly; for itemised splits, work out each share on paper or in a notes app, add the same percentage to each, and check that the shares add up to the bill total including tip — if they do not, someone's share is wrong.
Splitting by card deserves its own note: most restaurants can split a bill across cards, but splitting the tip across cards is a separate step, and some older systems cannot do it cleanly. The simplest approach is one card for the bill plus tip, settled between friends afterwards, or cash for the tip where the restaurant still accepts it. Whatever the method, agree it before the card machine arrives — the worst time to negotiate a split is while the server waits with the terminal.
Large parties: check for automatic gratuity first
Many restaurants add an automatic gratuity of 18 to 20 percent for parties of six or more, and this is the single most expensive tipping mistake: tipping a further 20 percent on top of an already-included 20 percent doubles the tip without anyone intending it. Before adding anything, read the bill for lines marked gratuity, auto-gratuity or service charge. If gratuity is included, you are done — the extra tip line on the receipt is for additional tipping only, and leaving it blank is correct. If no gratuity is included, tip at the usual 20 percent or more for a large table, because serving eight people well is genuinely harder work.
Service charge, gratuity and tip: three different things
A tip is voluntary: you decide whether to leave it and how much. A gratuity, when added automatically, is a charge the restaurant imposes, usually for large parties, and it is distributed to staff under the restaurant's policy. A service charge is a compulsory charge that belongs to the restaurant, not to the server, even when the restaurant later distributes some or all of it to staff. The distinction matters because a compulsory service charge is not a tip in law: sums distributed from service charges count as wages, not tips, and they are treated differently for tax and for minimum-wage calculations. If a bill carries a service charge and you also want to reward your server personally, add a tip on top — but do it knowingly, not by accident.
Bars, buffets, counters and takeout
At a bar, the convention is 1 to 2 dollars per drink for beer or wine and 2 to 3 dollars for cocktails, or 20 percent on a running tab settled at the end. At a buffet, where staff clear plates and refill drinks but do not take orders or serve courses, around 10 percent is usual, with 15 percent for attentive service. At a counter where you order and carry your own food, tipping is optional and 10 to 15 percent, or a dollar or two, is a common courtesy — tip screens that suggest 20 percent or more on a coffee you carried yourself are defaults set by the payment system, not obligations. For takeout, tipping is not expected in the same way, but around 10 percent is a normal courtesy, more for large, complex or carefully packed orders.
Paying by card: how the tip actually moves
Card tips travel through the restaurant's payroll rather than straight into a pocket: you write the tip on the receipt or pick a percentage on a handheld terminal, the restaurant records it, and the server receives it through payroll, with taxes withheld. That routing is why card tips are fully recorded and why servers sometimes prefer cash, which they keep the same night. It also explains a quirk worth knowing: where a card company charges the restaurant a percentage fee on card sales, the restaurant may pass that percentage of a card tip on to the server as a deduction, but only up to the actual fee and never below the minimum wage — a protection that exists precisely because tips belong to the employee.
Tips, tip pools and the law in brief
Under United States federal law, tips are the property of the employee. An employer may take a tip credit toward the minimum wage — paying a direct cash wage as low as 2.13 dollars an hour federally, with tips making up the difference to the 7.25 dollar federal minimum — but only where the employee is properly informed and actually receives enough in tips, and the employer must make up any shortfall. Valid tip pools are allowed, but only among employees who customarily receive tips when a tip credit is taken, and managers, supervisors and owners may not take a share of other employees' tips. The United States Department of Labor Fact Sheet 15 sets out these rules in full, and state laws that are more protective than the federal floor apply instead of it. None of this changes what you write on the receipt, but it explains why tipping is not a bonus on top of a full wage in much of American hospitality — it is a core part of how service staff are paid.
Tipping outside the United States
In much of Europe, service is included in the menu price or a discretionary service charge of around 12.5 percent is added, and no further tip is expected; rounding up or leaving small change is a courtesy, not a duty. In the United Kingdom, a discretionary service charge can be asked to be removed if service was poor, and since October 2024 employers there must pass tips and service charges they control to workers in full. In Japan, tipping is not customary and can even cause confusion, while in parts of the Middle East and Asia a service charge is standard and an extra tip is optional. The rule for travellers is simple: check whether service is included before tipping, and tip generously where the local system depends on it and lightly where it does not.
Mistakes to avoid
Double-tipping on an automatic gratuity is the costliest mistake. Tipping on a post-tax total while believing you tipped on the subtotal is harmless but worth knowing. Leaving nothing for poor service punishes the server for problems — kitchen delays, understaffing, a wrong order from the pass — that are usually outside their control; 10 to 15 percent plus a word with the manager is fairer and more effective. And tipping a percentage on a bill that already includes a large service charge, without reading the bill first, is the same double-payment in a different costume. Read the bill, then decide.
Delivery apps and digital tip screens
Tipping has moved beyond the restaurant table into apps and payment terminals, and the customs there are still settling. Food delivery apps typically suggest percentages at checkout — often 15, 20 and 25 percent — and the tip you choose there is usually the driver's pay for that trip, not a restaurant tip, so the same percentages apply with a different recipient. Many apps let you adjust the tip after delivery, which is the right tool for a delivery that went badly or brilliantly, and a few minutes spent adjusting beats either overpaying for a cold order or underpaying a driver who battled weather and traffic.
Tip screens at counters — the tablet turned toward you with 18, 20 and 25 percent buttons — deserve a calmer response than they usually get. Those percentages are defaults chosen by the business or its payment provider, not obligations, and for counter service where you carried your own food, a smaller tip or none at all is perfectly acceptable. Tip fatigue is real, and it is driven less by generosity than by pressure: a screen that asks for 25 percent on a coffee creates resentment that spills onto the next genuine tipping occasion. The antidote is the same rule as at a table — decide the tip from the service, not from the screen — and remember that pressing custom amount and entering your own figure is always an option, however small the button.
Frequently asked questions
How much should I tip at a restaurant?
For good sit-down service in the US, 18 to 20 percent of the pre-tax bill. Fifteen percent is a floor for adequate service, and 20 to 25 percent rewards service that stood out.
Should I tip on the pre-tax or post-tax amount?
Traditionally the pre-tax subtotal. Tipping on the post-tax total is common and slightly more generous; on an everyday meal the difference is usually under a dollar.
What if gratuity is already added to my bill?
Then you have already tipped. Check for a gratuity or auto-gratuity line for parties of six or more before adding anything else — the extra tip line is optional.
How do I split a restaurant bill fairly?
Split evenly when orders were similar. When they differed sharply, split by what each person ordered plus a share of shared items, with the same tip percentage applied to each share.
Do I have to tip on takeout?
No, it is optional. Around 10 percent is a common courtesy, especially for large or complex orders, but there is no expectation comparable to table service.
Is a service charge the same as a tip?
No. A compulsory service charge belongs to the restaurant, even if it is later shared with staff, while a tip is voluntary and belongs to the employee. A service charge does not replace a tip unless the restaurant says so.
The Bottom Line
Read the bill, tip 18 to 20 percent on the pre-tax subtotal for good service, and split by what people ordered when it matters. That is the whole etiquette, and the Tip Calculator on this site will do the arithmetic while you enjoy the meal.
