Split any bill — with tip and tax — evenly across a group.

Group dining ends in mental arithmetic nobody enjoys at the table. This splits the whole bill evenly after applying your chosen tip — then rounds each share up to whole cents so nobody owes fractional pennies. The rounding creates a tiny over-collection (at most ¢1 per person) that covers the tip rounding gap rather than shorting the server.
Even splitting stays fair when orders cost similarly. When one friend's steak triples another's salad, itemize instead: sum individual items, divide only the shared tax and tip proportionally. A fair itemized method: each person pays their items plus (their items ÷ subtotal × shared tax) plus (their items ÷ subtotal × tip) — the calculator handles the even case here; run uneven tables with one pass per person through the math.
Tax already included in the entered total is treated as informational extraction: total × tax% ÷ (100 + tax%) estimates the tax slice for ledger purposes, not as an extra charge. Use it when expensing — the net (total minus implied tax) is usually the business-deductible amount, with tax on its own line.
Tipping on pre-tax versus total is the perennial debate; this calculator tips the entered total. To tip pre-tax strictly, enter the pre-tax subtotal as total and add tax informally afterward — the difference on an $80 pre-tax bill with 8% tax is about $1.15 at 18% tip, meaningful over a year of dining. Check for auto-gratuity first (common for 6–8+ diners) so you don't tip twice.
Cash handling and payment mechanics: card processors take ~2–3% plus flat fees, so one card covering the bill while others reimburse via instant transfer avoids multiple card fees. When someone pays cash short (e.g. $40 on a $43 share), round up their share and let the card payer absorb the difference rather than chasing coins — or have the group agree on one payer with transparent reimbursement.
For large or recurring shared expenses (roommates, trip funds, team meals), recordkeeping beats arithmetic: a shared note with date, total, tip, tax and per-person shares prevents the slow resentment of untracked imbalances. This calculator's output is that record's source row — copy it into the shared ledger after each event.
Split any bill — with tip and tax — evenly across a group. Formula: per-person = total × (1 + tip%) ÷ people. Example: $124.80 with an 18% tip becomes $147.26 total.

$124.80 with an 18% tip becomes $147.26 total. Four ways, that's $36.82 per person (exact: $36.8145). An uneven case: $40 steak + $12 salad on an $80 subtotal with $10 tax and $16 tip — steak diner owes $40 + $5 + $8 = $53 proportionally, not $36.82 even — showing when itemized splitting matters.
