Splitting a bill is a small problem with a long history of causing friction: someone orders the expensive dish, someone else drinks only water, and the arithmetic at the end decides whether the evening ends well. An even split is the fastest defensible answer, and for most groups eating roughly similar meals it is also the fairest, because over many dinners the imbalances cancel.
This page divides a total by a headcount and optionally adds a service percentage across the whole party before dividing. That ordering — total, then gratuity, then division — is what makes it different from the Tip page, which starts from a bill and builds upward.
grand total = amount × (1 + tip per cent ÷ 100)
each pays = grand total ÷ people
The amount you enter is treated as the pre-gratuity total of the table. Everything is divided at the end, so the service percentage is shared proportionally: a 10 per cent addition on a 240 bill adds 24 and each of four diners pays 6 of it. The headcount accepts from one to two hundred people, which covers anything from a couple to a catered event, and the currency selector changes presentation only.
One structural point about what is not here: there is no notion of individual orders. The page cannot know that one person had the steak and another had soup, so it cannot produce a fair split of an itemised receipt. It answers the even-split question and nothing else.
The defaults. 240 across four people with no tip: the grand total stays 240.00 and each person owes 60.00.
Adding service. 240 across three people with 10 per cent added: the grand total is 240 × 1.10 = 264.00, and each pays 264 ÷ 3 = 88.00. Note that the tip landed on the table as a whole, not on individuals, so nobody was charged for someone else's wine.
When it does not divide evenly. 100 across three people with no tip gives 33.3333… per head, displayed as 33.33. Three times 33.33 is 99.99, leaving a cent unaccounted for. The tool reports the exact per-person figure; the cent is a rounding artefact of writing it down, not an error in the division.
A larger table. 480 across twelve with 15 per cent: grand total 552.00 and 46.00 each, exactly, because 552 divides cleanly by twelve.
Before, in effect, because the page multiplies the total by the service factor and then divides. The two orderings give the same per-person number as long as everyone shares the gratuity equally, which is why the tool does the division last.
This page will not do it. Take each person's own subtotal, add their share of the gratuity, and sum the results — or agree on eating the difference on the next outing, which is what most groups actually do.
Direction of travel. The Tip page begins with a bill, works out a gratuity and then divides. This page begins with what the table owes, adds service as a whole and divides. Choose by which number you already have in front of you.
The results update as you type, so adjusting the party size or the percentage recalculates immediately and the per-person figure is the last thing computed.
No. The arithmetic happens in the browser and nothing is uploaded or stored.
