Splitting a bill with a tip, step by step

A restaurant bill is three numbers pretending to be one: the food, the tax, and the tip. Getting the per-person amount right means keeping them straight and only then dividing.

  1. Enter the bill. Type the total from the receipt. If the receipt shows a subtotal and a separate tax line, enter the subtotal and add the tax rate — that way the tip is calculated on the food alone, which is the customary way to do it in most of the United States.
  2. Pick a tip percentage. The quick buttons cover the usual range. 15% is the old standard, 18% is a normal sit-down dinner, 20% is what most people leave when service was good, and 25% is for something above and beyond. You can type any number you like instead of using a button.
  3. Set the number of people. This is the divisor. It applies to the food, the tax and the tip together, so nobody gets stuck paying a share of a tip they did not agree to.
  4. Read the per-person figure. The result is what each person owes. The card below it breaks the total into food, tax, tip and the final amount, so you can show the table how the number was reached.

Questions

Should the tip be calculated on the pre-tax or post-tax amount?

Custom in the US is pre-tax, because the tax is not the server’s work. In practice most people tip on the total because it is one less step. On a $100 bill with 8% tax the difference between the two at 20% is $1.60, which is why almost nobody argues about it. This tool lets you do either: enter the subtotal to tip pre-tax, or enter the full total to tip on everything.

How much should I tip?

In the US: 18–20% for sit-down table service, 15% for counter service where someone still brings the food, 10–15% with a $3 minimum for delivery, and $1–2 per drink at a bar. In most of Europe a service charge is already included and rounding up is enough. In Japan tipping is not done and can cause confusion.

What is the fastest way to work out 20% in my head?

Move the decimal one place to get 10%, then double it. On $84.50, 10% is $8.45 and 20% is $16.90. For 15%, take the 10% and add half of it again. This is worth knowing because it lets you sanity-check any app, including this one.

Should we split evenly if some people drank and others did not?

Evenly is fine for a group where the difference is a few dollars and the social cost of itemising is higher than the money. It stops being fine when one person orders a $60 bottle and everyone else had water — at that point pay for the drinks separately and split the food here.
