Standard in the US is 15-20% for sit-down restaurants. 10% for takeout. 20-25% for exceptional service.
Enter the number of people and we divide the total (bill + tip) equally among everyone.

Settle the bill in seconds — tip, split, and per-person totals, all live.
In the US, 15% is the floor for acceptable service, 18–20% is standard, and 25%+ signals exceptional service. In Europe and most of Asia, service charges are usually included and a 5–10% top-up suffices when warranted.
Strictly speaking, tip is calculated on the pre-tax subtotal. In practice many people tip on the post-tax total because the math is easier and the difference is small.
A flat 10% is customary for takeout where staff bagged and packaged your order. No tip is acceptable for simple counter pickup, especially at quick-service restaurants.
No — tips are gratuities by definition. That said, in tipping cultures (US, Canada) less than 15% for sit-down service is generally read as a complaint. Large parties often have an automatic service charge already added.
Use itemized splitting: each person pays their own items plus a proportional share of tax and tip. For a quick fix, sort the bill into rough thirds (cheap / medium / expensive eaters) and assign accordingly.
End-of-meal mental arithmetic is one of those small everyday tasks that quietly causes friction. The ConvertDox Tip Calculator removes the friction: enter the bill, pick a tip percentage, set how many people are splitting, and the per-person share appears immediately. Preset tip buttons at the most common percentages (15%, 18%, 20%) handle the typical case; the custom field handles everything else, including the increasingly common scenario of paying through a kiosk that suggests 22%. The calculator updates live as you change any input, which is faster than typing on a phone keypad and confirming each digit. Because the whole thing runs in your browser, there's no sign-up, no app to install, and no data leaves your device — useful if you don't want a restaurant chain's analytics service knowing what you ate. The tool is responsive and works on phones, so you can pull it up at the table without an awkward delay. If you split bills regularly with the same group, save the page to your home screen and the calculator launches like an app. Beyond meals, it's useful for taxi fares, delivery orders, salon visits, hotel housekeeping, and any other service where tipping is customary — anywhere you'd otherwise be doing percentage math in your head while five people stare at you.
