An equal split is simple math: (subtotal + tax + tip) ÷ number of people. Where groups get into trouble is dividing before adding tip and tax — a $120 dinner for four is not $30 each once you add 8.5% tax and a 20% tip; it's about $38.75. This calculator always applies tip and tax to the full bill first, then divides, so the per-person figure is what each person actually owes.
Itemized mode works differently: each person's ordered items form their personal subtotal, and tax and tip are then allocated in proportion to that subtotal — not per head. If your items came to $40 of a $100 check, you cover 40% of the tax and tip too. That proportional allocation is what makes an itemized division genuinely fair when one person had the steak and another had a side salad. Custom-weight mode generalizes the same idea: assign each person a percentage or weight (say 2 shares for a couple, 1 for a single guest) and every component of the bill follows those weights.
In the US, the convention is to tip on the pre-tax subtotal, though many people simply tip on the total — the difference on a typical dinner is well under a dollar per person, so consistency matters more than the method. Watch for a service charge or "large party gratuity" (often 18% for groups of 6+) already printed on the check: if it's there, set tip to zero or you'll double-tip. Tax-inclusive menus, common outside the US, mean you should skip the tax field entirely.
Division rarely comes out to whole cents. $100 among three people is $33.33 each, leaving a stray penny — standard practice is for the person who paid the check to absorb (or pocket) the remainder. The round-up option instead nudges each share to a clean figure like $34, which makes cash settlement painless and gives the payer a small buffer. Two other edge cases worth agreeing on before the check arrives: someone who left early or skipped the wine can be handled with itemized or custom weights, and if the group is treating a guest of honor, divide the whole bill by everyone except them.
