Tip Calculator
A tip calculator helps you calculate the appropriate tip amount and split the bill among friends when dining out. Tipping is a common practice in restaurants, cafes, bars, and for services like haircuts, taxis, and deliveries, especially in the United States where tipped workers often rely on tips as a significant part of their income. This calculator takes three inputs: the bill amount before tip, the tip percentage you want to give, and the number of people sharing the bill. It then shows the tip amount, the total bill including tip, and how much each person owes. In the US, a tip of 15-20% is standard for good service at sit-down restaurants, with 18% being a common default. For exceptional service, 20-25% is appropriate. For poor service, 10-15% may be given. In many other countries, tipping is less expected or not expected at all, so the norm varies by culture. Splitting a bill evenly is the simplest approach, but you can also calculate per-person tips if people ordered different amounts.
Formula
Tip = Bill x (Tip% / 100) Total = Bill + Tip Per Person = Total / People Where: Bill = Pre-tip bill amount Tip% = Tip percentage (e.g. 18 for 18%) People = Number of people splitting
Example
Example: Bill is $100, tip 20%, split among 4 people. Step 1: Calculate the tip Tip = 100 x (20 / 100) = $20 Step 2: Total including tip Total = 100 + 20 = $120 Step 3: Split per person Per person = 120 / 4 = $30 Result: On a $100 bill with a 20% tip, the total is $120. Split 4 ways, each person pays $30 ($25 for food + $5 for tip).

Frequently Asked Questions
How much should I tip at a restaurant?
In the United States, 15-20% is standard for sit-down restaurant service. 18% is a common default for good service, 20% or more for exceptional service, and 10-15% for below-average service. For buffets or counter service, 10% is typical. In many European and Asian countries, service is included in the bill and tipping is less common or not expected.
Should I tip before or after tax?
The standard practice is to calculate the tip on the pre-tax bill amount, not on the total including tax. However, many people simply tip on the total for convenience, and the difference is small. For example, on a $100 bill with 8% tax, tipping 18% pre-tax gives $18, while tipping on the total gives $19.44.
What is a fair way to split a bill among friends?
The simplest method is to split the total evenly, which works well when everyone ordered similar items. If people ordered very different amounts, it is fairer for each person to pay for what they ordered plus their share of shared items and the tip. Some apps can split by item automatically.
Is tipping mandatory in the US?
Tipping is not legally mandatory, but it is strongly expected for sit-down restaurant service in the US. In many states, tipped workers can be paid as little as $2.13 per hour, with tips expected to make up the difference to the minimum wage. Not tipping for adequate service is considered rude. Some restaurants add an automatic gratuity of 18-20% for large groups.
Should I tip for takeout or delivery?
For delivery, tipping $3-5 or 10-15% is standard. For takeout picked up in person, tipping is less expected but appreciated, especially if the restaurant provided extra service like packaging sauces separately. A dollar or two, or 10%, is a nice gesture for takeout.
How do I calculate tip quickly without a calculator?
A quick mental math trick: to calculate 20%, move the decimal point one place left (that gives 10%) and double it. For 15%, take 10% and add half of that amount. For 18%, take 20% and subtract a little. For example, on a $45 bill, 10% is $4.50, so 20% is $9 and 15% is $6.75.
