About this tool
This free online tip calculator works out the tip and total for any bill, and splits it between any number of people. Enter the bill, choose a tip percentage (or tap a quick preset), and set how many are sharing. Everything updates instantly and runs in your browser with no upload.
How to use
- Enter the bill amount.
- Set the tip percentage or tap a preset.
- Enter the number of people to see per-person amounts.
Choosing a percentage
In the United States, 15–20% is the working range for table service, and 20% has quietly become the default in most cities. Outside that context the norms change sharply: service is typically included in much of Europe, rounding up is sufficient, and tipping is not customary at all in Japan or South Korea. Before adding anything, check the bill for a service charge line — automatic gratuities are standard for large groups, and tipping on top of one means paying twice.
Percentages also suit some situations better than others. At a bar, a flat amount per drink is the usual convention, because 20% of a large round bears no relation to the work involved. For counter service and takeaway, a smaller percentage or nothing at all is normal despite what the payment terminal suggests.
Splitting fairly when orders differ
An even split is fastest and works when everyone ordered roughly the same. When they didn't, it quietly transfers money from the person who had soup to the person who had steak and two cocktails. The practical middle ground is to subtotal each person's items and apply the same tip percentage to each — the tip stays proportional and nobody has to compute percentages individually.
Expect the per-person figure not to divide cleanly. A 100 total across three people is 33.33 each with a cent left over; the convention is that someone absorbs it rather than the table reconciling to the penny.
Pre-tax or post-tax
Tipping on the pre-tax subtotal is the more logical choice, since sales tax is collected on behalf of the government rather than earned by the restaurant. The practical difference is small — under a dollar on a typical bill — so it matters less than people arguing about it suggest. Enter whichever amount you consider the base and the percentage applies to that.
Common uses
Settling a restaurant bill quickly, splitting a shared check without an argument, working out gratuities for delivery or a hotel service, and checking whether an automatic service charge already covers it.

Frequently asked questions
How do I calculate a tip?
Multiply the bill by the tip percentage and divide by 100. For a 50 bill at 18%, the tip is 9 and the total is 59. This calculator does it instantly and can split the total between people.
What's a standard tip percentage?
In the US, 15–20% is common for table service, with 18% a frequent default and 20% increasingly treated as the baseline in cities. The quick-tip buttons cover 10, 15, 18, 20, and 25%. Counter service, takeaway, and bars follow different conventions — a flat amount per drink is normal at a bar, where a percentage of a large round can be excessive.
How do tipping norms differ between countries?
Enormously, and assuming the US model travels badly. Tipping is largely absent in Japan and South Korea, where it can be mildly insulting. Much of Europe includes service in the bill and rounding up is enough. Australia and New Zealand treat tips as optional for exceptional service. Always check whether a service charge is already on the bill before adding anything.
Should I tip on the pre-tax or post-tax amount?
The pre-tax subtotal is the more defensible base, since tax is money the restaurant never sees. In practice the difference is small — on a 50 bill with 8% tax, tipping 20% pre-tax versus post-tax differs by about 80 cents. Enter whichever figure you prefer; the calculator applies the percentage to what you give it.
What if a service charge is already included?
Then the tipping has been done for you, and adding a full tip on top means paying twice. Look for a line reading "service charge", "gratuity", or "service compris", which is common for large groups and standard in many countries. If one is present, either add nothing or round up slightly.
How do I split a bill when people ordered very differently?
An even split is the fastest option and is fine when orders are broadly similar, but it quietly overcharges whoever had a salad and water. When the spread is wide, total each person's items separately, then apply the same tip percentage to each subtotal — that keeps the tip proportional without anyone doing per-item percentage maths.
Why does the per-person amount not divide evenly?
Because currency stops at two decimal places and thirds don't. A 100 total split three ways is 33.33 each, leaving a cent unaccounted for. The usual convention is that one person rounds up by the remaining cent or two — trying to make the numbers reconcile exactly is not worth the effort at the table.
Is my data uploaded anywhere?
No. The calculation runs entirely in your browser with no upload, and the bookmarklet version works the same way on any page.
