Tip Calculator
Split bills and calculate tips
The Tip Calculator takes a bill total, a tip percentage, and the number of people splitting the cheque, and tells you exactly how much each person owes. It is built for the situation everyone has been in: a dim restaurant, a long bill, and someone reaching for their phone to do math.
Adjust the tip percentage with one tap to try common gratuity levels (15%, 18%, 20%, 25%) and see the new per-person total instantly.
What it calculates
- Tip amount in absolute currency.
- Bill plus tip total.
- Per-person total when split across the chosen number of people.
How tip is computed
Tip = bill × (tip percentage / 100). Total = bill + tip. Per-person = total / number of people.
In the United States, tip is typically calculated on the pre-tax subtotal, although many people simply tip on the post-tax total. Both are common and acceptable; this calculator lets you enter whichever base you prefer.
Worked example
Bill of $86.40, 20% tip, split between 4 people:
- Tip =
86.40 × 0.20 = $17.28 - Total =
86.40 + 17.28 = $103.68 - Per person =
103.68 / 4 = $25.92
When to use this
Restaurants, bars, group dinners, and rides where everyone is paying their share. Useful for travellers who are not yet used to local tipping norms — keeping a calculator handy avoids accidentally over- or under-tipping.
A note on tipping customs
Tipping norms vary significantly by country. In the United States, 18–20% is standard for sit-down service. In much of Europe, service is often already included and additional tipping is modest. In Japan, tipping is generally not expected and can even be refused. Use local guidance when traveling.
Frequently asked questions
Should I tip on tax?
It is a matter of preference. Many people tip on the pre-tax subtotal, which is slightly more economical and considered the technically correct base.
What is a standard US restaurant tip?
For sit-down service, 18% is standard and 20% is generous. For exceptional service, 22%–25% is appropriate.
Does this round per-person amounts?
No — the per-person figure is the exact split. If you want to round up so the math is easier in cash, simply increase the tip percentage slightly.
