How This Bill Splitter Works
Enter the bill total before tip — the pre-tax subtotal from the restaurant receipt. Select the tip percentage using one of the preset buttons (10%, 15%, 18%, 20%, 25%) or type a custom rate into the input. Adjust the number of people up or down and the calculator updates in real time. The results show the total tip amount, the grand total, and what each person owes broken out as bill per person plus tip per person, so anyone at the table can independently verify the math in about five seconds.
We defaulted to 18% tip because that is the most common rate used at US casual dining restaurants and the point where most servers consider the baseline for table coverage. The 20% preset is useful for groups that want clean round numbers — 20% of $100 is $20, which makes the mental math easy when you want to verify the calculator independently. For counter service or fast-casual where the tip is discretionary, the 10% or 0% custom input are the appropriate modes. Use the tax and tip calculator if you need to add local sales tax to the subtotal before splitting.
Tip Percentages: What They Actually Mean
The 18-20% range that most etiquette guides recommend for full-service restaurant dining reflects a combination of labor economics and social convention. Most restaurant servers in the US are paid a "tipped minimum wage" — as low as $2.13 per hour in many states — with the expectation that tips will bring total compensation to the regular minimum wage or above. Tips are the primary income source, and the 15-20% convention built up over decades as a rough way to compensate service staff appropriately per hour worked without customers doing detailed labor math at the table. Higher-end restaurants in service-intensive markets and cities often run toward 20-25% as the implicit floor among regular diners.
The payment terminal pressure for 20-25-30% suggestions is a merchant-set default, not a social norm shift. The suggested amounts on card terminals are configured by the restaurant and do not represent a consensus view on appropriate tipping — they represent an optimization of average tip per ticket. The socially neutral range remains 18-20% for adequate service at a sit-down restaurant.
