How this is worked out

The formula

total with tip = bill × (1 + tip%)
even split: each = total with tip ÷ people
uneven: one person = total × share%;  others = (total − one person) ÷ (people − 1)

  • The uneven share is a percentage of the total including tip; everyone else splits the rest equally.

About this calculator

Enter the bill, how many people are paying and the tip, and you get what each person owes with the tip built in. For the friend who ordered the lobster, open More options and give one person a set share of the bill — everyone else splits what's left evenly.

How to use it

  • Bill total is the pre-tip amount on the check (tax included, as printed).
  • Tip applies to the whole bill and is divided among everyone. Set it to 0 if service is already included.
  • One person's share (More options) is a percentage of the bill. If one person's items came to about 40% of the total, enter 40. Their tip scales with their share, which is the fair way to do it.

Reading the results

Each person pays is the headline number for the even members of the group. When an uneven share is set, the calculator shows both that person's amount and what everyone else pays. The table shows what the same bill costs per head with 2 to 10 people — useful before deciding whether to invite the extra couple.

Rounding and the last cent

Dividing $186.50 plus 18% by four gives $55.0175 each. Round to the nearest cent and the group is a few cents short or over; someone covers the difference. If everyone pays by card, most POS systems split evenly and put the odd cent on the last card.

Evenly or by item?

Splitting evenly is fast and works when everyone ordered similarly. It goes wrong when one person had a $14 salad and another had three cocktails. A quick compromise is to give the outliers a share percentage here and let the rest split evenly. For a full itemised split, each person adds their items, then multiplies by (1 + tax rate + tip rate) — tax and tip should be shared in proportion to what you ate, not divided per head.

Beyond restaurants

The same math splits a holiday rental, a group gift, a bar tab, or a taxi. For rent, set tip to 0 and use the share percentage for the person with the bigger bedroom.

Frequently asked questions

How do I split a bill with tip?

Add the tip to the bill first, then divide by the number of people. $186.50 with an 18% tip is $220.07, or $55.02 each for four.

How do you split a bill unevenly?

Give the person with the larger share a percentage of the total (including tip), then divide the remainder equally among the rest. This calculator does that with the 'One person's share' option.

Should tip be split evenly or by what each person ordered?

Ideally in proportion to what each person ordered, since tip is a percentage of the bill. If you split the bill by items, each person's tip is their subtotal × tip rate.

Is tax split evenly?

Tax is proportional to what was ordered, so strictly it follows the same shares as the food. Splitting a bill that already includes tax evenly is fine when orders were similar.
