小费给多少合适？
小费习惯因地而异。在美国，堂食 15–20% 是标准：服务一般给 15%，不错给 18–20%，非常好给 20% 以上。很多餐厅对 6–8 人以上的聚餐自动加收 18–20% 服务费——先看账单，别重复给了。外卖和柜台点餐小费随意，给 10% 已经很大方。
怎么 AA 分账
输入税前账单，拖动小费滑杆，选择分账人数。计算器会显示小费金额、总计和每人应付。打开凑整，现金结账不用找零钱。
小费按税前还是税后算？
Etiquette says tip on the pre-tax subtotal. In practice the difference is small (a few cents on a typical bill), so most people tip on the total out of convenience. This calculator lets you enter tax separately and tips on the pre-tax amount by default.
常见问题
What is a good tip percentage?
In the US: 15% adequate, 18–20% good, 20%+ excellent. In much of Europe and Asia, service is included and rounding up is enough — check local norms when traveling.
Do I tip on the pre-tax or post-tax total?
Traditionally pre-tax. The difference is usually under a dollar, so either is fine socially.
How do I split a bill evenly?
Add tip (and tax) to get the grand total, then divide by the number of people. Use the round-up option to get clean per-person amounts.
What about large groups?
Restaurants often auto-add 18–20% gratuity for 6+ diners. Look for “service charge” on the bill before adding more.
Is the tip calculated before or after discounts?
Before — tip on the original subtotal, not the discounted price. Your server did the same work.
