Advanced Tip & Split Bill Calculator

Calculate restaurant tips, gratuity amounts, total bill costs, tip percentages, and split bills between multiple people.

Advanced Tip & Split Bill Calculator

Work out the tip on a bill, the total including gratuity, and each person's share when splitting between several people. Enter the bill amount, choose a tip percentage, and set the number of people.

Formulas

The calculation is straightforward:

  • tip = bill × tip rate (for example, 18% is a rate of 0.18)
  • total = bill + tip
  • per person = total / number of people

Some groups prefer to tip on the pre-tax amount. In that case use the pre-tax subtotal as the bill in the first formula, then add tax back before splitting.

Worked example

A dinner bill comes to $80.00, the group tips 18%, and four people are splitting evenly:

  • Tip: 80 × 0.18 = 14.40
  • Total: 80 + 14.40 = 94.40
  • Per person: 94.40 / 4 = 23.60

Each person pays $23.60, which covers the food and a $3.60 share of the tip.

If the bill were $84.60 instead, the 18% tip is 84.60 × 0.18 = 15.228, which rounds to $15.23, for a total of $99.83 and $24.96 per person (the payer covering the extra cent).

When to use this calculator

  • Restaurants and bars: get the tip and each diner's share settled quickly instead of doing mental arithmetic at the table.
  • Group outings: splitting a shared taxi, tour, or delivery order evenly among friends.
  • Service appointments: tipping hairdressers, movers, or delivery drivers where a percentage guideline applies.
  • Travel: checking what a customary tip amounts to in an unfamiliar currency before you pay.

Tipping customs vary

Customary tip rates differ widely by country and by type of service, so treat any percentage as a convention rather than a rule:

  • In the US, 15% to 20% is typical for table service, with 20% increasingly the default in cities; counter service is often less.
  • In much of Europe, a service charge may already be included, and rounding up or leaving 5% to 10% is common.
  • In some countries, including Japan and South Korea, tipping is not customary and can even cause confusion.
  • Check the bill for an automatic gratuity or service charge before adding a tip on top; large groups are often charged one automatically.

Tips for splitting fairly

  • An even split is simplest, but if orders differ a lot, split the food individually and share the tip and tax in proportion to each person's subtotal.
  • Rounding each share down can leave the total short; round the per-person amount up to the nearest convenient figure, or let one person absorb the leftover cents.
  • When paying by card, confirm whether the terminal's suggested percentages are calculated on the pre-tax or post-tax amount; the difference is small but real.
  • Cash tips typically reach staff directly, which some diners prefer even when paying the bill by card.

Frequently asked questions

How do I calculate a tip?
Multiply the bill by the tip rate: tip = bill × rate, so an 18% tip on an $80 bill is 80 × 0.18 = $14.40. Add the tip to the bill for the total, and divide the total by the number of people to split it evenly.
What is a normal tip percentage?
It depends on the country and the service. In the US, 15% to 20% is customary for table service; in much of Europe, rounding up or 5% to 10% is common because a service charge is often included; and in countries such as Japan, tipping is not customary at all.
Should I tip on the pre-tax or post-tax amount?
Convention varies, and either is acceptable in the US; tipping on the pre-tax subtotal is the traditional guideline, while card terminals usually suggest percentages of the post-tax total. On a typical bill the difference is small, roughly 1 to 2% of the total.
How do I split a bill fairly when orders are very different?
Instead of an even split, total each person's own items, then share the tax and tip in proportion to those subtotals. An even split still works well when orders are similar or the group prefers simplicity.
What if the bill already includes a service charge?
Check the bill before adding a tip; many restaurants add an automatic gratuity, often 18% or more for large groups, and some countries include service by default. When service is already charged, an extra tip is optional and usually small.
