Splitting a restaurant bill and figuring out an appropriate tip shouldn't require mental math at the table. This tool calculates the tip amount, total bill, and per-person split instantly.
A custom that varies dramatically by country and has genuinely contested origins
The practice of tipping has several competing origin stories — some trace it to European aristocratic customs of giving small gratuities to servants for extra attentiveness as early as the 17th century, while its establishment as a standard American restaurant practice is generally traced to the years following the Civil War, though the custom was genuinely controversial in the U.S. for decades, with several states actually passing (and later repealing) anti-tipping laws in the early 20th century, partly on the grounds that it created an undesirable, undemocratic servant-master dynamic. Tipping norms remain famously inconsistent internationally even today — an expected practice with specific unwritten percentage conventions in the United States, essentially unnecessary or even considered mildly insulting in some other countries where service charges are already built into prices or wages.
How the calculation works
The tool multiplies your bill total by your chosen tip percentage to calculate the tip amount, adds that to the original bill for the total amount due, and — if splitting among a group — divides that total evenly by the number of people, though many tools (and this one) also let you split just the tip, or handle situations where the bill itself should be split unevenly by what each person actually ordered.
Where a tip calculator is genuinely useful
- Restaurant and bar service — the most common use case, quickly determining an appropriate tip based on a chosen percentage and splitting the total among a dining group.
- Delivery and rideshare services — many delivery and rideshare apps suggest tip percentages, and understanding the actual dollar amount those percentages represent helps with quick, informed decisions.
- Salon, spa and personal service appointments — tipping conventions extend well beyond restaurants to many personal care services, where similar percentage-based calculations apply.
- Group travel and shared expense situations — splitting a tip-inclusive total fairly among a group of friends or colleagues sharing a meal or service.
Frequently asked questions
What's considered a standard tip percentage in the United States? Conventions vary somewhat by region and type of service, but 15-20% of the pre-tax bill total is a commonly cited standard range for restaurant table service in the U.S., though actual practice and expectations continue to shift over time and vary by specific establishment and service quality.
Should I tip on the pre-tax or post-tax total? Conventions vary, and reasonable people disagree, but many etiquette guides suggest calculating the tip based on the pre-tax subtotal, since tax is a government charge unrelated to the service quality being tipped for — though tipping on the full post-tax total is common practice too and generally not considered incorrect.
Why is tipping culture so different between countries? Largely a function of differing minimum wage laws and labor norms — in countries where service workers, particularly restaurant staff, are guaranteed a full standard minimum wage regardless of tips, tipping tends to be less expected or entirely optional, unlike in the U.S., where a lower "tipped minimum wage" for service workers in many states makes tips a genuinely significant portion of expected income.
