What it calculates
It calculates gratuity on a bill, the new total, and the exact per-person share when splitting.
Why it matters
Tipping norms vary widely by country and service type, and splitting in your head at the table invites errors.
Who it's for
Diners, travellers, and anyone settling a group bill.

Worked example
$86.40 bill, 18% tip, 4 people
- 1Tip = 86.40 × 0.18 = 15.55
- 2Total = 86.40 + 15.55 = 101.95
- 3Split = 101.95 ÷ 4

How the tip calculator works
Tip = bill × rate. Total = bill + tip. Per person = total ÷ people. Tip on the pre-tax amount if you want to be precise; tipping on the gross total is simply slightly more generous.
Enter the pre-tip bill, pick a percentage and set how many people are splitting it. Each share includes an equal slice of the tip.
Typical US table service runs 15–20%; counter service and many countries outside North America expect far less or nothing at all.
Common mistakes
- Tipping on a total that already includes a service charge.
- Rounding down per person and leaving the table short.
Tips and best practice
- In the US, 18–20% is standard for table service; in much of Europe, 5–10% or rounding up is normal.
- Round the per-person share up to the nearest whole unit to keep the split simple.
Frequently asked questions
How much should I tip?
In the United States 15–20% for restaurant service is customary. Norms are lower across most of Europe and Asia.
Should I tip on tax?
Tipping on the pre-tax subtotal is standard practice, though many people simply tip on the total.
How do I split a bill unevenly?
Calculate the tip on the whole bill, then apportion it in the same proportion as each person's items.
Should I tip on the pre-tax or post-tax amount?
Strictly, on the pre-tax subtotal, since sales tax is not part of the service. Tipping on the total is simply a little more generous and is very common.
What is a standard tip in the US?
15% is the low end for adequate table service, 18–20% is standard, and above 20% signals genuinely good service. Counter service and takeaway have far lower expectations.
Do I still tip when a service charge is included?
Usually not. A service charge or automatic gratuity — common for large groups — already covers it, so check the bill before adding more.
