How much should I tip?

In the US: 15–20% for table service, 10–15% for delivery, and $1–2 per drink at a bar. Many other countries tip less or include service in the bill.

Should I tip on the pre-tax or post-tax amount?

Etiquette says pre-tax, though many people tip on the total for simplicity. Enter whichever amount you want the percentage applied to.

Run the calculation with the full bill first to get the total, then assign shares manually. A weighted split option is on the roadmap.

Enter the bill, choose a tip percentage and the number of people to see the tip, the total, and exactly what each person owes.

Enter the bill amount — use the pre-tax subtotal if you follow strict tipping etiquette.
Set the tip percentage. For US table service, 15–20% is standard; 18% is a solid default.
Enter how many people are splitting — per-person amounts appear as soon as there are two or more.
Use Share so the whole group sees the same math on their own phones.

How the tip and split are calculated

Tip = bill × tip% ÷ 100 · Per person = (bill + tip) ÷ people

The tip is computed on the pre-tax bill you enter. Splitting divides the grand total evenly; for uneven splits, adjust per person manually.

An $85 bill with an 18% tip adds $15.30, for a $100.30 total — $50.15 each between 2 people.

US norms: 15–20% for table service, 10–15% for delivery, $1–2 per drink at a bar, about 10% at buffets.
Tipping on the pre-tax vs post-tax amount changes the tip by only a dollar or two on a $100 bill at typical tax rates.
In much of Europe and Japan, service is included in the price and tipping is minimal or not expected at all.
Rounding the final total (not the tip) to a whole number keeps group splits clean.

It is computed on exactly the bill you entered. Enter the pre-tax subtotal if you want etiquette-strict tipping.

An even split of the grand total. For uneven shares, run each person's own subtotal as a separate calculation.

A 'service charge' or 'gratuity included' line on the bill usually replaces the tip — adding more on top is optional, not expected.
