Tip Calculator with Split & Custom Percentage

Tip, total, and an even three-way split

An $86.40 bill with an 18% tip comes to a tip amount of $15.55 and a total of $101.95. Split evenly 3 ways, that's $33.98 per person.

The 18% tip is calculated on the pre-tip bill amount ($86.40 x 18% = $15.552, rounding to $15.55) -- if the bill already includes tax, this calculates the tip on that tax-inclusive total, which is a common and generally accepted convention, though some people prefer tipping only on the pre-tax subtotal.

Per-person amount ($33.98) is the total ($101.95) divided evenly by 3 -- this is a straight equal split, which doesn't account for one person ordering significantly more or less than the others, a separate negotiation this simple even-split calculator doesn't attempt to solve.

What 'tax-inclusive' means for this calculation

Even split only. Tax-inclusive bills are treated as the number you type. Whatever number you enter as 'bill' is treated as the base the tip percentage applies to -- if you want to tip only on the pre-tax subtotal rather than the tax-inclusive total, enter the pre-tax amount specifically rather than the full receipt total.

This produces one tip amount and one even split -- if your group wants to tip a different percentage than 18%, or split unevenly based on who ordered what, those are different calculations this basic even-split tool doesn't handle beyond adjusting the tip percentage and people-count fields.

Rounding at the per-person level ($33.98 x 3 = $101.94, one cent less than the actual $101.95 total) is a common, unavoidable artifact of splitting a dollar amount evenly among a number that doesn't divide it perfectly -- in practice, one person typically covers that extra penny or two.

For splitting shared costs on a trip beyond just a restaurant bill (like a group vacation with multiple shared expenses), a broader bill-splitting approach would track each category separately, which this single-bill tip calculator doesn't attempt.

For calculating fuel costs on a road trip -- another common travel-expense-splitting scenario -- the Fuel Cost & Trip Distance Calculator handles that specific shared cost.
