About this calculator

How to use

  1. Enter the bill amount.
  2. Pick a tip percentage — use the quick buttons or type your own.
  3. Set how many people are splitting the bill.
  4. All four amounts update instantly: tip, total, per-person, and tip-per-person.

The formula

Tip amount     = bill × (tip% / 100)
Total          = bill + tip
Per person     = total / people
Tip per person = tip / people

Worked example

Dinner bill of $87.50, 18% tip, split 3 ways:

  • Tip: $87.50 × 0.18 = $15.75
  • Total: $87.50 + $15.75 = $103.25
  • Per person: $103.25 / 3 = $34.42
  • Tip per person: $15.75 / 3 = $5.25

Notes

  • Results are rounded to the nearest cent.
  • The calculator requires at least 1 person (negative or zero people default to 1).
  • For a party of 10 or more, many restaurants automatically add an 18–20% gratuity — check your bill before adding more.

Frequently asked

How is the tip amount calculated?
Tip = bill × (tip% / 100). Total = bill + tip. Per-person = total / number of people. Tip per person = tip / number of people.
What is the standard tip percentage?
In the US, 15–20% is standard for sit-down restaurant service. 18–22% is more common in cities. 20% is increasingly the default option on card readers. For counter service or takeout, 10–15% (or nothing) is typical.
Should I tip on the pre-tax or post-tax amount?
Most etiquette guides say tip on the pre-tax total — tip on service, not the government cut. Either way is acceptable; the difference is usually small.
How do I split a bill unevenly?
This calculator divides evenly by default. For uneven splits, calculate the total with tip, then divide according to each person's share of the pre-tip bill.
Can I share a tip calculation?
Yes — press "Share with my numbers" to encode your bill, tip %, and party size in the URL and copy it to your clipboard.
