How to Calculate a Tip

How to calculate a tip fast: 10%, 15%, 18% and 20% mental math, plus exact bill splitting with the free tip calculator.

How Much Should You Tip?

In the United States, the common range is 15% to 20% for good service. Many people tip 15% for average service, 18% to 20% for good service, and more for exceptional service. For big bills, a higher percentage still earns its keep in hospitality jobs.

Quick Mental Math for Common Tips

  • 10%: move the decimal point one place left. A $48.00 bill gives a $4.80 tip.
  • 15%: take 10% plus half of 10%. For $48.00, that is $4.80 + $2.40 = $7.20.
  • 20%: take 10% and double it. For $48.00, that is $9.60.

Use the Tip Calculator to Be Exact

Splitting the Bill Fairly

Enter the total bill and the number of people, and the calculator shows each share, including the tip. If one person ordered more, simply figure their item cost, apply the same tip percentage, and the calculator gives their fair share.
