Enter your bill amount
A tip calculator takes your restaurant or service bill and instantly works out the gratuity, the total you owe, and each person’s share when you split the check. Instead of doing percentage math at the table — often on a phone with a dying battery — you enter the bill once and get clean, exact numbers you can trust.
How to Calculate a Tip: The 3 Formulas
A tip calculator multiplies your bill by the tip percentage, adds the tip to the bill, and divides by the number of people when you split the check. These are the three formulas it runs every time you change a value:
Total bill = Bill + Tip amount
Amount per person = Total bill ÷ Number of people
Worked example: on a $100 dinner with an 18% tip, the tip is $100 × 0.18 = $18.00, the total is $100 + $18 = $118.00, and if four people split it evenly, each pays $118 ÷ 4 = $29.50.
How Much Should You Tip? A US Tipping Guide by Service
As of 2026, 18–20% is the de-facto standard at US sit-down restaurants — 15% now reads as the minimum for adequate service, not the norm it was a decade ago. Apply percentages to the pre-tax subtotal, tip toward the top of the range for great service, and check the worldwide table below before assuming US norms travel with you.
| Service | Standard Tip (US) |
|---|---|
| Sit-down restaurants | 18–20% of the pre-tax bill |
| Bars (bartender) | $1–2 per drink, or 15–20% of the tab |
| Food delivery | 10–15% ($2–5 minimum) |
| Takeout / counter service | Optional — 10% appreciated |
| Coffee shops | $1 or about 10% |
| Taxi / rideshare | 10–15% of the fare |
| Hair salon / barber | 15–20% |
| Hotel housekeeping | $2–5 per night |
| Valet parking | $2–5 when your car is returned |
| Spa / massage | 15–20% |
| Tour guides | $5–10 per person |
Should You Tip on the Pre-Tax or Post-Tax Total?
Tip on the pre-tax subtotal. Standard US etiquette bases the percentage on the bill before sales tax is added — most receipts print the subtotal on its own line, and that is the number to use. Tipping on the post-tax total is generous, but no server expects it.
The difference is real money: on a $100 meal with 8% tax, a 20% tip on the $100 subtotal is $20.00, while 20% on the $108 post-tax total is $21.60 — tipping post-tax costs you an extra $1.60 on this one meal alone.
Mental-Math Shortcuts: Tip Without a Calculator
No calculator handy? These four shortcuts handle any common percentage. Try them on a $46.50 bill:
20%: double the 10% figure → $4.65 × 2 = $9.30
15%: take 10%, then add half of it → $4.65 + $2.33 = $6.98
18%: take 20%, then subtract a tenth of it → $9.30 − $0.93 = $8.37
Round the final tip to the nearest dollar if you like — on a $46.50 check, $8.37 becomes a clean $8 or a generous $9.
Watch Out: Auto-Gratuity and Double Tipping
Always scan the receipt before you add a tip. Restaurants commonly add an automatic gratuity of 18–22% for parties of 6 to 8 or more — tipping again on top of it means double-tipping by accident.
Also watch the wording: a service charge is set by the business and the house may keep some or all of it — it is not the same as a tip that goes to your server. The same trap exists in delivery apps: the “service fee” or “delivery fee” goes to the company, not your driver, so your tip is a separate line item. When in doubt, ask “is gratuity included?” before you pay.
Tipping Around the World
US tipping norms do not travel. If you are eating out abroad, the local rule may be the opposite of what you expect:
| Where | The Custom |
|---|---|
| United States & Canada | 15–20% expected; tipping is factored into workers’ pay |
| United Kingdom | 10–12.5% discretionary — check the bill for a service charge first |
| Much of Europe | Service often included in menu prices; rounding up or 5–10% for great service |
| Japan | Do not tip — it can be seen as insulting; excellent service is standard |
| Australia & New Zealand | Tipping optional; around 10% for outstanding service |
The one-sentence takeaway: in North America tipping is close to obligatory, in much of Europe it is a bonus, and in Japan it is a faux pas. The calculator above works with any currency — just enter your local bill amount.

When It’s OK Not to Tip (Tip Fatigue)
Tip screens are everywhere now — coffee counters, food trucks, self-checkout kiosks — often pre-set to 18%, 20%, or 25%. Here is the honest rule: if nobody served you at a table, tipping is optional. Tapping “$0” or “Custom” at a counter where you ordered standing up is completely fine, even if the employee is watching.
Bad table service is the other case people agonize over. Dropping to 10% sends the signal without stiffing the server — and if the service was genuinely awful, speak to a manager instead of leaving nothing with no explanation. Silence teaches no one; a calm word to the manager might actually fix the problem.
Frequently Asked Questions
How much should I tip at a restaurant in the US?
As of 2026, tip 18-20% of the pre-tax bill at sit-down restaurants in the US. Treat 15% as the minimum for adequate service, and go to 20% or more for great service. Tipping norms have drifted upward over the past decade, so the old 15% baseline now reads as the floor, not the standard.
Do you tip before or after tax?
Tip before tax, on the pre-tax subtotal. Most receipts list the subtotal on its own line, and standard US etiquette bases the percentage on that number. Tipping on the post-tax total is generous but not expected.
What is 20% tip on a $50 bill?
A 20% tip on $50 is $10, for a total of $60. The math: $50 x 0.20 = $10 tip, then $50 + $10 = $60 total. If two people split it evenly, each pays $30.
What is 15% tip on $100?
A 15% tip on $100 is $15, for a total of $115. The math: $100 x 0.15 = $15 tip, then $100 + $15 = $115 total. Split four ways, that is $28.75 per person.
How do I calculate an 18% tip quickly in my head?
Take 20% of the bill, then subtract a tenth of that amount. On a $60 bill, 20% is $12, a tenth of $12 is $1.20, so 18% is $10.80. See the mental-math section above for the full set of shortcuts.
How much should I tip for food delivery (DoorDash / Uber Eats)?
Tip 10-15% of the food subtotal for delivery, with a $2-5 minimum on small orders. Go to the top of the range for bad weather, long distances, or large orders. Note that app service fees and delivery fees go to the company, not your driver – the tip is a separate line item.
What should I do if the restaurant already added gratuity to my bill?
Do not add a second tip on top of it. Restaurants commonly add an automatic gratuity of 18-22% for parties of 6-8 or more, so scan your receipt for ‘gratuity’ or ‘service charge’ before paying. You can still add a little extra for exceptional service, but it is optional.
How do I split a bill with tip among friends?
Add the tip to the bill first, then divide the total by the number of people – that is exactly what the calculator above does. If orders were very unequal, split the food cost by what each person ordered and divide only the tip evenly. Agree on the method before the check arrives.
Is it rude not to tip in the United States?
In most full-service settings, yes. Tipping is factored into how US service workers are paid – the federal tipped minimum wage is $2.13 per hour – so gratuities make up most of their income. If service was genuinely bad, speak to a manager rather than leaving nothing with no explanation.
Do you tip hotel housekeeping? How much per night?
Yes – leave $2-5 per night for hotel housekeeping, in cash on the pillow or nightstand each morning. Staff often rotate, so tip daily rather than once at checkout, ensuring the person who cleaned your room actually gets it.
What’s the difference between a service charge and a tip?
A tip goes to the service worker; a service charge is a fee set by the business, and the house may keep some or all of it. Adding a tip on top of a service charge can mean double-paying without the worker getting more. Always read the receipt, and if you see ‘service charge’ or ‘auto-gratuity,’ add nothing extra unless you choose to.
Should I tip on alcoholic drinks the same as food?
Yes – tip 15-20% on drinks at a restaurant, the same as food. At a bar, $1-2 per drink or 15-20% of the tab is the norm. If you received a happy-hour discount, consider tipping on the full undiscounted price.
