About this tool
A simple bill-splitting calculator. Enter the bill amount, tip percentage, and how many people are splitting; see the per-person total. Includes a quick-reference line showing the tip in dollars at 15% / 18% / 20% so you can pick the right round-number tip on the fly. Tip etiquette (US): 15% for adequate service, 18% standard, 20% for excellent. Many places now suggest 25-30% on the receipt — that's above customary, not required.
What this calculator does
This calculator splits a restaurant or service bill across any number of people at any tip percentage. It returns the tip amount, total bill, tip per person, bill per person before tip, and a quick-reference line showing the dollar tip at 15%, 18%, and 20% so you can pick a round-number tip on the fly. The math is plain percentage arithmetic — no jurisdictional adjustments — though the FAQ section covers the etiquette and tax/wage law that shape what people actually leave.
How it works — the formula
Tip = bill × (tip% / 100)
Total = bill + tip
Per person = total / number of peopleTipping math is straightforward percentage arithmetic. The conventional pre-tax US tip range is 15% (adequate), 18% (standard), 20% (excellent). Tips are taxable income (IRS Pub 531) and the employer pays its share of FICA on reported tips. The federal "tipped-employee" cash wage of $2.13/hr survives under the FLSA tip-credit provision (29 USC §203(m)); several states mandate the full minimum wage on top of tips.
Worked examples
- Inputs:
- bill = $80, tip = 18%, people = 4
- Output:
- Tip = $14.40; total = $94.40; per person = $23.60
Standard US sit-down service. 18% is the typical baseline; the per-person figure rounds neatly so each diner can settle in cash without making change.
- Inputs:
- bill = $250, tip = 20%, people = 8
- Output:
- Tip = $50; total = $300; per person = $37.50
Large parties often hit an auto-gratuity (typically 18%) baked into the check. Confirm the bill before adding a second tip on top — the most common cause of accidental double-tipping.
- Inputs:
- bill = $100
- Output:
- 15% = $15.00 | 18% = $18.00 | 20% = $20.00
Round-base example — useful for mental math. At $100 base, every 1% of tip equals $1, so deciding between 18% and 20% is a $2 question per person.
When to use this vs other tools
Tip Calculator handles the dining math. For the percentage math behind it or the wage / tax angle, reach for one of the related tools.
- Percentage Calculator
Use for any percent-of-X arithmetic outside dining: discounts, markups, percent change. Tip Calculator is just this specialised for restaurants plus an n-way split.
- Salary to Hourly Calculator
Use to understand the wage side of tipping. Under the FLSA tipped-employee provision, the federal cash floor can be as low as $2.13/hr — this tool shows how that compares to the equivalent annualised wage in your state.
- Tax Bracket Calculator
Use when budgeting around tipped income — IRS Pub 531 requires all received tips to be reported as taxable income, which moves a tipped worker's effective bracket more than people expect.
- Profit Margin Calculator
Use on the business side. Restaurants typically run 3–5% net margin; understanding margin clarifies why "just add 18% to your card" matters more than diners realise.
Authority note
IRS Pub 531 governs the tax treatment of tips for both worker and employer. The FLSA tip-credit provision sets the federal cash-wage floor for tipped employees; many states (CA, OR, WA, NV, MT, MN, AK) override it with the full minimum wage on top of tips.
Limitations
- Tipping conventions vary by country. The US treats tipping as effectively mandatory; much of Europe, Japan, and Australia treat it as optional or even rude.
- "Service charge" already added to a bill (common at large parties) replaces the tip — do not double-tip.
- Tax inclusion in the base is jurisdiction-specific; this calculator tips on the pre-tax bill by convention.
- Cashless tipping increases the IRS-reported portion and the employer's share of FICA, which affects worker take-home.
Tipping is a social custom, not a regulation. This calculator does not provide tax or wage advice — refer to IRS Pub 531 and DOL guidance for the legal/tax treatment of tips.
