Bill Split Calculator

Multiply the pre-tax subtotal by the tip percentage written as a decimal. For example, 18% on $80 = 80 × 0.18 = $14.40 in tip.

In the United States, 15% to 20% is standard for full table service, with 18% a common default. For exceptional service, 20% or more is a good acknowledgment. For buffets or limited service, 10% is usually enough. This calculator lets you set any tip percentage.

Tipping on the pre-tax bill is customary, which is how this tool calculates it. Tipping on the full post-tax total is also acceptable and only adds a little.

Rounding every share up to the nearest cent guarantees the group always covers the full bill plus tip, so the table is never left short.

This calculator divides the total into equal shares. If orders varied widely, the fairest approach is for each person to total their own items first, then apply a tip on top. A separate itemized split is more accurate when orders differ a lot in price.

Many restaurants automatically add an 18% to 20% gratuity for parties of six or more. Check the bill before adding your own tip so you do not pay twice.

The simplest way is for one person to pay and the others to send them their share. If you prefer to pay separately, ask the server to split the check before you order, since many restaurants can do it as they ring up the orders.
