Evenly or by order, with the tip and rounding

Split a restaurant bill between friends evenly or by what each person ordered, with shared dishes divided between everyone, the tip added to each share and every share rounded up so the table covers the bill.

To split a bill evenly, add the tip and divide by the number of people: a 140 bill with an 18% tip between four is 165.20 ÷ 4 = 41.30, or 42 each rounded up. If people ordered different things, switch to by-order mode: everyone pays for their own order and an even share of anything shared, with the tip added to that.

Shares are rounded up so the money collected always covers the bill, and the calculator shows how much is left over.

How to use

Choose how to split: evenly or by order.
For an even split, enter the bill and the number of people. By order, put each person on a line with a name and an amount, and anything ordered for the table under Shared items.
Enter the tip percentage and the step to round each share up to.
Read who pays what, the total collected and left over, the Working lines and the table of shares at other tips.

How to split a bill evenly

Share = bill × (1 + tip ÷ 100) ÷ number of people. A 140 bill with an 18% tip for four: 140 × 1.18 = 165.20, and 165.20 ÷ 4 = 41.30. With the same percentage for everyone, a tip on the whole bill and a tip on each share come to the same: 18% of 140 is 25.20, and four times 18% of 35 is also 25.20.

A 140 bill between four, rounded up to a whole number. Worked out with this calculator.
Tip	Bill with tip	Exact share	Each, rounded up
0%	140	35	35
10%	154	38.50	39
15%	161	40.25	41
18%	165.20	41.30	42
20%	168	42	42

How to split a bill by what each person ordered

Everyone pays for their own order plus an even share of what was shared, and the tip goes on top of that: (own order + shared ÷ people) × (1 + tip ÷ 100). Ann had 24, Ben 38, Cara 16 and Dan 31, and the table shared appetizers for 21, which is 5.25 each:

A 130 bill, 153.40 with the tip. The shares shown to the cent add up to 153.42 because each is rounded; rounded up to whole numbers they collect 156. Worked out with this calculator.
Who	Order	Shared	Tip 18%	Total	Pays
Ann	24	5.25	5.27	34.52	35
Ben	38	5.25	7.79	51.04	52
Cara	16	5.25	3.83	25.08	26
Dan	31	5.25	6.53	42.78	43

Several items for one person

Add items up on the line: “Ben 15+23” counts as 38. A name is optional, so a line reading “16” becomes a numbered guest. Lines without an amount are skipped and listed separately, so nothing goes missing.

Why shares are rounded up

Rounding to the nearest can leave the table short: Ben's 51.04 rounded to the nearest whole number is 51. Rounding up always collects at least the bill: 168 against 165.20 for the even split, and 156 against 153.40 by order, with 2.60 left over. How much to tip is covered by the tip calculator.

What to keep in mind

Shared items are split evenly between everyone listed.
Shares are rounded up to the step chosen; without rounding they add up to the bill with the tip exactly.

FAQs

How do I split a bill evenly?

Add the tip to the bill and divide by the number of people: 140 plus 18% is 165.20, and 165.20 ÷ 4 = 41.30. Rounded up to a whole number, everyone pays 42.

How do I split a bill when everyone ordered different things?

Each person pays for their own order plus an even share of anything shared, with the tip added to that. Ann's 24 plus a 5.25 share of the appetizers, with an 18% tip, comes to 34.52.

Should the tip be on the whole bill or on each share?

With the same percentage the total tip is the same: 18% of 140 is 25.20, and four times 18% of 35 is also 25.20. By order, each person's tip is in proportion to their share.

Why round shares up rather than to the nearest?

So the money collected always covers the bill. Rounded to the nearest whole number, Ben's 51.04 becomes 51 and his share falls short; rounded up it is 52.

How do I split shared dishes?

Evenly between everyone at the table: 21 of appetizers between four is 5.25 each. In by-order mode, enter them under Shared items.

Can I list several items for one person?

Yes, add them up on the line: “Ben 15+23” counts as 38.

Worked example

Input: 140 between four people, 18% tip, rounded up to a whole number

Output: 42 each

Note: The exact share is 41.30. Rounding up collects 168 against 165.20 with the tip, leaving 2.80 over.
