How tipping works
In most US restaurants, servers earn a low base wage and depend on tips, which is why 15-20% of the bill is standard for good service. Some guides suggest tipping on the pre-tax bill rather than the total, but tipping on the total is also common. This calculator handles either — just enter the number you want to use as the bill.
For larger groups, many restaurants add a "service charge" or an automatic gratuity (often 18%) to parties of six or more. If you see a service charge already added, don't tip again — check the receipt before deciding the percentage.
