How it works
Most tip calculators apply a percentage to the pre-tax subtotal you enter. If your table tips on the post-tax total, add tax first or raise the tip percent slightly to match house custom. Splitting by headcount assumes equal shares; adjust for shared appetizers, separate checks, or guests who did not drink. Service charges already on the bill may replace a tip—read the receipt before stacking another percentage. Rounding to whole dollars is for convenience at the table, not a legal requirement.
Input guidance
- Enter the pre-tax subtotal unless you tip on the post-tax bill by local custom.
- Choose a tip percent that matches service and local norms.
- Set guest count only when splitting evenly—adjust manually for uneven shares.
The formula
Tip = bill × tip rate. Total = bill × (1 + tip rate). Split per person = total ÷ number of people.
Worked example
A $80 bill at 18% adds $14.40 for a $94.40 total; split among 4 people that is $23.60 each.
More examples to test
- $86.40 subtotal at 18% tip for 3 people: compare per-person totals.
- Same bill with a service charge already included: confirm whether an extra tip is expected.
How to interpret results
Use the split as a table convenience. Receipt service charges and cash-vs-card customs can change the final amount.
When this can be inaccurate
Does not model automatic gratuity rules, coupon adjustments, or shared appetizers with unequal eaters.

In the US, 15–20% for sit-down service is typical, with 20% common for good service. Norms vary widely by country.
How do I split a bill with tip?+
Add the tip to the bill first, then divide by the number of people for an even, fair share.
Why are outputs slightly different from another tool?+
Different tools can use different rounding rules, default assumptions, and treatment of edge cases.
How can I improve estimate reliability?+
Use verified inputs from real records and re-run calculations after major assumption changes.
