Tipping can be confusing โ different countries, services, and situations call for different amounts. This tip calculator handles the math so you can focus on the meal or service itself. Enter your bill amount, choose a tip percentage, and see the tip amount, total, and per-person share if splitting.
The calculator includes quick-select buttons for the most common US tipping percentages (15%, 18%, 20%, 25%) plus a custom option for any percentage. You can also round the total to a convenient number and split the bill among any number of people with equal shares.
Tipping customs vary globally, but in the United States, tips are a significant portion of service workers' income. Understanding proper tipping etiquette and working out the math cleanly helps you stay fair to the server while staying within your budget.
Use the result to compare scenarios, test assumptions, and revisit the model when pricing, volume, or financing inputs change.
Mental math with 18.5% on a $73.42 bill after two glasses of wine is not anyone's strong suit. This calculator gives you the tip and split amounts quickly so you never under-tip (awkward) or over-tip (budget impact) unintentionally.
The bill-splitting feature is equally valuable. Splitting "evenly" when one person ordered less is always uncomfortable โ use the per-person amount as a starting point and adjust from there with confidence.
Tip Amount = Bill ร (Tip% / 100)
Total = Bill + Tip Amount
Per Person = Total / Number of PeopleResult: Tip: $17.00 | Total: $102.00 | Per Person: $25.50
An $85 bill with a 20% tip: $85 ร 0.20 = $17 tip. Total = $85 + $17 = $102. Split 4 ways: $102 / 4 = $25.50 per person.
Tipping customs vary dramatically by country. In the US and Canada, 15-20% is standard for restaurants. In the UK, 10-12.5% is common. In Japan, tipping can be considered rude โ exceptional service is simply expected. In many European countries, service charge is included in the bill. Australia uses a "no tip expected" culture with occasional rounding up. Always research local customs before traveling.
In the US, the tipped minimum wage is just $2.13/hour in many states. Tips often constitute 60-80% of a server's take-home pay. The tipping system has been criticized for creating income instability and shifting labor costs from businesses to customers. Some restaurants have experimented with no-tipping policies (higher menu prices, higher base wages), with mixed results.
Point-of-sale systems (Square, Toast, etc.) now present tip screens at every counter, making tipping decisions more frequent and visible. Common screen options are 15%, 20%, 25% โ but these are suggestions, not requirements. For counter service, any tip from $1 to 15% is generous. Do not feel pressured by the screen. For sit-down service, use the percentage that reflects the quality of service received.

In the US, 15-20% is standard for restaurant dining. 20% has increasingly become the baseline for good service. For other services: hairdressers 15-20%, taxi/rideshare 15-20%, food delivery 15-20%, hotel bellhop $1-2/bag, valet $2-5.
Etiquette experts say tip on the pre-tax subtotal. However, tipping on the post-tax total is common and acceptable โ it just means a slightly larger tip. The difference is typically small (8-10% sales tax adds less than 2% to the tip).
In the US, tipping is not legally required but is a strong social norm. Service workers often earn below minimum wage ($2.13/hour for tipped workers in many states) and depend on tips. Not tipping for acceptable service is considered rude. In many other countries, tips are not expected or are included in the bill.
Many restaurants automatically add a gratuity (typically 18-20%) for parties of 6 or more. Check your bill before adding an additional tip. If auto-gratuity is included, additional tipping is optional but appreciated for exceptional service.
Equal split is simplest but not always fair. For significantly different orders, ask the server for separate checks. Alternatively, have each person calculate their individual items + proportional tax and tip. Venmo and similar apps make this easier.
For counter service (you order and pick up), tipping is appreciated but optional โ typically $1 or spare change. For table service at a coffee shop, tip as you would at a restaurant (15-20%). The tip jars and screen prompts are suggestions, not obligations.
