How to Use This Tip Calculator
Using this tip calculator is simple and instant.

Enter the number of people splitting the bill, and toggle on Round Up if you'd like each person's share rounded to the nearest dollar, which simplifies cash payments. All results update in real time as you type — no calculate button, no page reload.
What Is the Standard Tip Percentage in the US?
Tipping norms in the US have shifted upward over the past two decades. The traditional standard was 15%, but 18–20% is now the baseline for competent sit-down restaurant service. Many Americans default to 20% and go higher for exceptional experiences.
- 15%: Once the standard; now often signals service that fell short of expectations.
- 18%: Solid service — a reasonable default at many casual restaurants.
- 20%: The new baseline for good service and the easiest percentage to calculate mentally.
- 22–25%: Excellent service, attentive staff, or nights when the server went above and beyond.
- 25%+: Exceptional experiences, regulars building relationships, or special occasions worth celebrating generously.
How to Split a Bill Fairly Between Friends
The simplest approach is an even split: divide the total bill including tip by the number of people. This works perfectly when everyone ordered roughly the same amount. For groups where one person had cocktails and a steak while another had a salad and water, a proportional split — where each person pays tip based on their own bill share — is fairer. Use the Custom Split section on this page for exactly that: enter each person's order total and the calculator distributes tip proportionally.
When to Tip More — and When Less Is Acceptable
There are situations where tipping above the standard is genuinely appropriate. Tip more when your server managed a large, complex party with grace; a manager made a special exception for you; the restaurant was packed and service was still attentive; or you're a regular who wants to build goodwill. Lower tips may be appropriate for genuinely poor service — a server who was repeatedly rude, forgotten about your table for long periods, or made errors without apology. That said, consider whether poor service reflects kitchen issues outside the server's control before reducing the tip significantly.
Tipping Etiquette for Different Types of Service
Tipping varies significantly by context. Here's a quick reference for the most common service situations:
- Sit-down restaurants: 18–20% of the bill is the standard baseline.
- Counter service / takeout: Optional, but 10–15% is appreciated for large or complex orders.
- Food delivery: 15–20% with a minimum of $3–5 — drivers often pay their own fuel and vehicle costs.
- Bartenders: $1–2 per drink for simple orders, or 15–20% on a full tab.
- Hotel housekeeping: $2–5 per night, left daily as staff often rotate room assignments.
- Rideshare / taxi: 15–20%, more for help with luggage or exceptional service.
How to Handle Tipping on Large Group Bills
Many restaurants automatically add an 18–20% gratuity to parties of six or more. Always check your bill before adding a tip — double-tipping on a large bill is a common and expensive mistake. If the restaurant hasn't added a gratuity, using this calculator removes any awkward conversation at the table. Agree on a tip percentage as a group, use the calculator, and split the total. For groups where people ordered very different amounts, the Custom Split section below the results handles proportional splitting automatically.
The Math Behind Calculating a Tip Without a Calculator
When your phone isn't handy, quick mental math works well. For 20%: move the decimal one place left to get 10%, then double it. On an $85 bill: 10% = $8.50, doubled = $17.00. For 15%: find 10% ($8.50), then find half of that for 5% ($4.25), and add them ($12.75). For 18%: calculate 20% and subtract roughly one-tenth of the tip. These tricks get you close enough for casual dining — and when you want exact figures for larger groups or higher bills, this calculator gives you the precise number instantly.
