❓ Frequently Asked Questions
How much should I tip?
15% is considered standard for adequate service in the US, 18-20% for good service, and 25%+ for exceptional service. For takeout, 10-15% is common. In countries like Japan or South Korea, tipping is generally not expected.
How do I calculate a tip quickly in my head?
Find 10% by moving the decimal point one place left. For 15%, add half of 10%. For 20%, double 10%. For 25%, add 10% to 15%. Example: On a $64 bill — 10% = $6.40, so 20% = $12.80.
Should I tip on the pre-tax or post-tax amount?
Etiquette experts say tipping on the pre-tax (subtotal) amount is correct. However, many people tip on the total for simplicity. The difference is usually small (1-2%).
How do I split a tip fairly?
Divide the total (bill + tip) evenly, or have each person tip on their own subtotal. For uneven orders, some groups calculate individual tips. Our calculator splits the total evenly for simplicity.
What is the average tip in the US?
The average tip in US restaurants is about 18-20%. According to industry data, the national average has risen to around 19.5% in recent years. Delivery drivers typically receive 15-20%.
💡 Quick Mental Math
- 10% — Move decimal left one place
- 15% — 10% + half of 10%
- 20% — Double the 10%
- 25% — Divide bill by 4
🌍 Tipping Guide by Country
- 🇺🇸 USA — 15-25%
- 🇨🇦 Canada — 15-20%
- 🇬🇧 UK — 10-15% (service charge often included)
- 🇪🇺 Europe — 5-10% or round up
- 🇯🇵 Japan — Not expected
- 🇦🇺 Australia — Not expected (but appreciated)
Tipping conventions differ wildly by country and by service type. In the US, tipping is essentially mandatory for table service. In much of Europe and Asia, it's appreciated but rarely expected — and adding 20% can occasionally come across as offensive.
How tips and bill splits are calculated
Tip = bill × (tip percent / 100). Total = bill + tip. Per person = total / number of people. For uneven splits where each person ordered different amounts, calculate each person's pre-tip subtotal, multiply each by (1 + tip percent / 100), then add tax to each.
When to use this calculator
Use it for restaurant bills (15-20% standard in the US, less elsewhere). Use it for ride shares, food delivery, and other service tipping. The bill-split feature is most useful for large groups where mental math gets complicated, especially with mixed orders and a single check.
Worked example
A $87.50 dinner bill at 20% tip: tip = $17.50, total = $105. Split four ways: $26.25 per person. With a 'round up' option, each person could pay $27 and the slight overage goes to the server.
