Tip percentages and etiquette

Tipping is a standard practice in the United States for service workers in restaurants, bars, rideshare, delivery, and many other industries. The expected tip amount varies by service type and region.

For sit-down restaurants, 15% to 20% is standard for good service. 18% has become increasingly common in recent years as the baseline. For exceptional service, 20% to 25% is appropriate. For poor service, 10% to 15% may be warranted, though leaving nothing is also acceptable.

Other contexts have different norms: food delivery often expects 15–20%, rideshare services 15–20%, baristas and bartenders typically get $1–2 per drink or 15–20% of the bill, and hotel housekeeping usually receives $2–5 per night.

Splitting the bill among friends

When a group dines out and decides to split equally, you have two choices: tip on the per-person share or tip on the full bill and then split the total. This calculator shows the second approach: calculate the tip on the full pre-tip bill amount, add it to the bill, and divide the total. This is the fairest method because everyone contributes equally to the service charge.

Some groups prefer each person to tip individually on their own portion of the bill—adding 18% to their meal and paying that—but this requires keeping careful track of who ordered what and can lead to awkward arithmetic at the table.

When to round up

When splitting a bill and per-person amounts contain cents, consider rounding: one person covers the fractional cents, and everyone else rounds down. This keeps the process simple and fair. For example, if the total is $58.47 split three ways, that's $19.49 per person. Have one person pay $19.50 and the others pay $19.49.

Assumptions

  • The tip percentage is applied to the bill amount you enter; it does not distinguish between pre-tax and post-tax totals.
  • The tip is split equally among all people, regardless of what each person ordered.
  • Only the tip and bill are calculated; tax is not included in the results unless you enter a post-tax bill amount.
  • No rounding or payment method adjustments are made; results show exact amounts to the cent.

Frequently asked questions

›What is a standard tip percentage in the United States?

The standard tip for sit-down restaurant service is 15% to 20%, with 18% becoming increasingly common as the baseline for acceptable service. For excellent service, 20% to 25% is appropriate. For poor service, 10% to 15% may be warranted. The percentage can vary by region and type of establishment—casual fast-casual restaurants and food trucks often have lower expectations, while fine dining may see 20% as the minimum.

›Should I calculate the tip on the pre-tax or post-tax bill?

Conventions vary. In many parts of the US, tipping on the pre-tax subtotal is standard, since tip is calculated as a percentage of the service provided, not the tax. However, some people tip on the post-tax total. Both are socially acceptable. This calculator uses the amount you enter—if you enter the pre-tax subtotal, the tip will be on that; if you enter the post-tax total, the tip will reflect the higher amount.

›How should we split a bill if everyone ordered different amounts?

If everyone ordered different things and wants to be fair, calculate each person's exact share of the bill plus a proportional share of the tip. However, in practice, many groups simply split the total equally for simplicity, especially among friends. If cost differences are large, consider using separate payments or asking individuals with pricier orders to contribute more to the tip.

›What if I don't have cash and need to tip on a card?

When paying by card, the card reader or receipt will include a tip line where you can write or select your tip amount. The tip is added to your card charge. Some point-of-sale systems now show suggested tip amounts (often 15%, 18%, 20%, and 25%) to help you decide quickly. If you are unsure, 18% is a safe, widely accepted standard.

›Is tipping mandatory?

Tipping is not legally mandatory in the United States, but it is culturally expected for sit-down restaurant service, delivery, rideshare, and many service industries. In some places, a service charge may be automatically added (often for large groups), and you should check the receipt. If service was genuinely unacceptable, you have the right to tip less or not at all, but this is rare.

›What about other service industries—how much should I tip?

Tipping expectations vary: delivery services and rideshare typically expect 15–20%; baristas and bartenders get $1–2 per drink or 15–20% of the bill; hair salons and spas typically get 15–20%; moving companies might get $5–20 per person; and hotel housekeeping usually receives $2–5 per night. When in doubt, 15–18% is a safe default for service-based businesses.
