How to Calculate a Tip
The math is straightforward: a tip is a percentage of the bill. Three formulas cover everything our calculator does:
Tip = Bill × (Percentage ÷ 100)
Total = Bill + Tip
Per person = Total ÷ Number of people
For a $48.50 bill with a 20% tip, split between 3 people:
- Tip = $48.50 × 0.20 = $9.70
- Total = $48.50 + $9.70 = $58.20
- Per person = $58.20 ÷ 3 = $19.40
Three terms often used interchangeably are not always the same thing. A tip (or gratuity) is a voluntary payment added by the customer for service received. A service charge is a mandatory amount added by the establishment to your bill - common for parties of 6 or more (often called "automatic gratuity") and standard practice in many European restaurants. When a service charge is already included, an additional tip is not required, though customers sometimes leave extra for exceptional service.
Above the calculator, the Tip comparison table shows side-by-side results for the same bill at percentages from 0% to 40%, so you can quickly see what different tip levels would cost without re-entering the bill amount.
Tipping Norms in the US
In 2025, the average tip at full-service restaurants in the United States is 19.4%, based on Toast's analysis of card and digital payments across more than 140,000 locations (Q1 2025 Restaurant Trends Report). Quick-service tips average 15.8%. Cash tips are not included in these figures.
The standard has shifted over time. According to Cornell University researcher Michael Lynn's 2025 longitudinal analysis, the typical restaurant tip rose from 15% in the 1970s to 19-20% today. Many Americans now consider 18-20% the baseline for adequate to good service, rather than the older 15% norm.
Tipping norms in the United States are shaped by a unique wage structure: the federal tipped minimum wage has been $2.13 per hour since 1991. In states without higher tipped wages, service workers depend on tips for most of their income - which is why leaving no tip at a sit-down restaurant is widely seen as offensive, not just impolite.
According to Bankrate's 2025 Consumer Tipping Survey (sample of 2,445 U.S. adults, surveyed April-May 2025), only 35% typically tip at least 20% at sit-down restaurants, down from 37% the previous year. The share who "always tip" sit-down restaurant servers stands at 70%.
Mental Math Tricks
When a calculator isn't handy, you can estimate a tip in seconds using the 10% rule. Start by finding 10% of the bill, then build other percentages from there.
Take a bill of $87.50 as an example:
- 10% - move the decimal point one place to the left: $8.75
- 20% - double the 10%: $8.75 × 2 = $17.50
- 15% - 10% plus half of 10%: $8.75 + $4.38 ≈ $13.13
- 25% - quarter of the bill: $87.50 ÷ 4 = $21.88
For odd percentages like 18%, the easiest path is to round to the nearest familiar value (20% in this case) - the difference is small enough that the answer will still be close.
In practice, mental math is most useful for a quick sanity check or when splitting a bill between friends. For exact amounts, the calculator above handles rounding to cents and per-person totals automatically.

For services outside this table: spa or massage 15-20% (added at the end), hotel bellhop $1-2 per bag, tour guide $5-10 for short tours or more per person for full-day excursions. When in doubt, check the bill or signs at the establishment - some include automatic gratuity for parties of 6 or more.
Tipping Around the World
Tipping norms vary dramatically by region. In some countries it's expected and built into the wage system; in others, it's optional - or even considered rude. In Australia and New Zealand, tipping is genuinely optional thanks to higher minimum wages. When traveling, research local customs - the same gesture can mean very different things.
North America
North America has the most established tipping culture, driven largely by US wage practices.
- United States: 18-20% at restaurants standard - see sections above for details. Tipping is widely expected at most service interactions.
- Canada: Similar to US, 15-18%. Often calculated on the pre-tax amount. Quebec has the strongest tipping culture.
- Mexico: 10-15% at restaurants. Resort areas and tourist establishments expect closer to 15-20%; local places 10% is fine.
Europe
European tipping is generally lower-key. Service charges are often included by law, and rounding up is more common than calculating a percentage.
- France: A 15% service charge is included by law in restaurants ("service compris"). Additional small tip (€1-5) for exceptional service is appreciated but never required.
- Germany: Round up or add 5-10% for good service. Hand it directly to the server rather than leaving it on the table.
- United Kingdom: 10-12.5% in restaurants; often a "service charge" is already on the bill. Tipping not expected at pubs when ordering at the bar.
- Italy: A "coperto" (cover charge) is often included; no tip required. €1-2 or rounding up for good service is the norm.
Asia
Asia stands out for its low or no-tipping culture. In several countries, an offered tip can be refused or feel insulting.
- Japan: Tipping is not part of the culture and can be considered insulting. Service is included in pricing. The Japan National Tourism Organization advises against tipping; even at hotels, an offered tip may be politely returned.
- China: Not customary in local establishments, where it may embarrass staff. Becoming more accepted in international hotels and upscale tourist venues in major cities.
- South Korea: Tipping is uncommon and can feel out of place. Service is included; servers may even refuse tips.
- Thailand: Becoming more common in tourist areas, 10-15% appreciated in upscale restaurants. Not expected at local places or street food.
Middle East
Tipping is widely practiced across the Middle East, often at higher rates than in Europe. Service charges are common but additional tipping is still expected.
- United Arab Emirates: 15-20% expected at restaurants. Often a service charge is added, but additional tip is still customary.
- Jordan: 15% standard at restaurants. Hotel staff and guides expect tips - significant part of their income.
- Egypt: Tipping (called "baksheesh") is integrated into daily life. 10-15% in restaurants; small tips for many minor services (bathroom attendants, doormen, guides).
Latin America
Tipping practices vary by country in Latin America - generally less expected than in the US but still appreciated.
- Argentina: 10% at restaurants is standard for good service. Not always expected but appreciated. Cash preferred since many card readers don't process tip on receipt.
- Brazil: 10% service charge ("taxa de serviço") often included in restaurant bills. Additional tip optional; locals tip discreetly to avoid drawing attention.
- Chile: 10% standard at restaurants. In tourist areas or for foreigners, 15-20% may be expected.
- Colombia: 15-20%, closer to US-style tipping. Often included on the bill as "propina sugerida" (suggested tip).
Using This Calculator
This calculator has several features beyond the basic Bill / Tip % / Number of people inputs. Here's what each does and when to use it.
Tip comparison
The toggle in the right panel shows a comparison table with tip amounts and totals for ten preset percentages: 0%, 5%, 10%, 15%, 18%, 20%, 25%, 30%, 35%, 40%. The row matching your current tip % is highlighted. Useful when deciding between several tip levels without re-entering the bill amount.
Round per person
The rounding selector adjusts how per-person totals are displayed: Cents (exact, no rounding), Up (round up to the whole currency unit), or Down (round down). Useful when splitting between friends to avoid odd amounts. The label adapts to the selected currency - "Cents" for USD, "Pence" for GBP, "Paise" for INR, and so on.
Share link
Each calculation produces a URL containing your bill amount, tip %, number of people, rounding, and currency as hash parameters (for example: #bill=48.50&tip=20&people=3¤cy=USD). Copy the link and send it - the recipient opens the calculator with your exact values pre-filled. The hash is cleared from the address bar after loading, so the shared values don't linger in browser history.
Saved results
The Save button stores your current calculation. Saved entries appear in a table below the calculator showing date, time, and the data. Up to 30 results are kept in your browser's local storage; when you reach the limit, the calculator asks before replacing the oldest. Data stays on your device only - it isn't synced or sent anywhere.
Settings
The Settings panel toggles parts of the interface on or off: the share link, the rounding selector, the action buttons (Save/Reset/Copy), the saved results panel, and whether the calculator remembers your last bill, tip %, and number of people between visits. The "reset settings" button restores all toggles to their defaults.
Common Mistakes
Tipping looks simple, but a few common errors come up regularly. Here are the ones worth knowing:
- Tipping on the post-tax total. The convention in the US is to tip on the pre-tax subtotal, since sales tax goes to the government, not the establishment. Many people tip on the total with tax for simplicity - the difference is small per meal but adds up over time.
- Double-tipping with automatic gratuity. Many restaurants add an 18-20% automatic gratuity for parties of 6 or more. Always check the bill before adding extra - a line marked "service charge", "gratuity", or "auto-grat" usually means the tip is already included.
- Penalizing the server for kitchen issues. Slow food or a wrong dish is usually not the server's fault. If there's a problem with the kitchen, address it directly with the manager rather than reducing the tip - the server still did their part.
- Splitting equally when meals were unequal. If one person had appetizers and drinks while another had just water, an even split isn't fair. Either itemize (each person pays for what they ordered plus a proportional tip), or agree on the split before ordering.
- Guilt-tipping at counter service. Touchscreen tip prompts at quick-service counters (often pre-set to 15/20/25%) have become common. Counter service tipping is optional - choosing "No Tip" without explanation is perfectly acceptable, especially for takeaway orders where there was no table service.
For the pre-tax convention specifically, enter the pre-tax subtotal in the Bill amount field above rather than the final total with tax - the calculator works from whatever value you provide.
Frequently Asked Questions
Why is tipping expected in more places now?
Touchscreen payment systems have made it easy for businesses to request tips at counters and self-service kiosks, expanding tipping beyond traditional table service. According to Pew Research (2023), 72% of Americans feel tipping is expected in more places than five years ago. The trend is often called "tipflation" or "tip creep".
What is a good tip amount in 2026?
For sit-down restaurants in the US, 18-20% is the typical range, with 20% considered the baseline for good service. The average tip across full-service restaurants in Q1 2025 was 19.4% (Toast Restaurant Trends Report). For other types of service, see the "Tipping by Service" table above.
Should I tip on takeout or delivery?
Delivery: yes - 15-20% with a minimum of $3-5. The driver typically sees your tip amount before accepting the order. Takeout: optional. 10% is appreciated but not required, especially for orders that didn't involve table service.
Is it OK not to tip if the service was bad?
A 10% tip signals dissatisfaction without leaving the server with nothing. If a major issue occurred, address it with the manager rather than zeroing out the tip. The server's base wage in many US states is as low as $2.13/hour, so leaving no tip has an outsized impact on their income compared to other industries.
Is it better to tip in cash or by card?
Cash is often preferred by servers - they receive it immediately, while card tips can take days to reach them through payroll. That said, card tips are perfectly acceptable and create a paper trail. The choice usually doesn't affect the amount, only the timing.
Does a service charge replace the tip?
Usually yes. When a service charge is on the bill (often 18-20% for parties of 6 or more in the US, or standard in many European and Middle Eastern restaurants), an additional tip is not required. Adding extra is optional and reserved for exceptional service.
