Common Tip Percentages Explained

Tip percentages vary by country, by kind of service, and by personal judgment, so there is no single right number. This guide shows what the common percentages come to on typical bills, how much a few percent changes the total, and the questions worth asking before you choose.

How much a few percent changes

On a $60 bill, each percentage point adds 60 cents. Moving from 18% to 20% adds $1.20, and from 15% to 20% adds $3.00. The gap between percentages grows in proportion to the bill.

Customs vary

In the United States, etiquette guides commonly suggest around 15 to 20 percent for sit-down restaurant service. Elsewhere expectations can be very different: in some countries a service charge is added to the bill, and in others tipping is uncommon or a small round-up is usual. When travelling, check local guidance.

Questions to ask before choosing

  • Is a service charge already on the bill? If so, an additional tip may not be expected.
  • Are you tipping on the subtotal or on the total including tax? Both are common.
  • Was it table service, counter service, or delivery? Expectations often differ.
  • On a very small bill, would you rather leave a minimum amount than a percentage that comes to a few cents?

The 15, 18, 20, and 25% buttons in the Tip Calculator are shortcuts, not a recommendation — you can type any percentage, including 0.
