Tip Calculator & Bill Splitter: What Each Person Owes
Work out the tip, split the bill evenly or by what each person actually ordered, and round each share up to a clean number — with a per-person table that adds up to the total exactly. Choose whether to tip on the pre-tax subtotal or the full check, in eleven currencies. Nothing is uploaded.

TL;DR
The tip itself is one multiplication: tip = base × percent. Everything that makes a bill awkward happens afterwards — deciding whether the base includes tax, working out what someone owes when they only had a salad, and stopping four rounded numbers from adding up to less than the bill. This calculator handles all three: tip on the pre-tax subtotal or the full check, an even split or a per-person split with the tip shared proportionally or equally, and a round-up option that shows the tip percentage you actually left afterwards. Every per-person figure is computed in whole cents, so the column always reconciles to the total.
The arithmetic, written out
A tip calculator has no secrets, so here is the whole thing. The bill splits into a pre-tax subtotal and a tax amount. You pick which of those the tip is calculated on. The tip is added, and the result is divided between the people at the table — either equally, or in proportion to what each person ordered.
tip base = subtotal (pre‑tax) or subtotal + tax (post‑tax)
tip = tip base × (percent ÷ 100)
grand total = subtotal + tax + tip
even split: each = grand total ÷ people
uneven split: each = own items + own tax + own tip
own tax = tax × (own items ÷ subtotal)
own tip = tip × (own items ÷ subtotal) ← proportional
own tip = tip ÷ people ← even
The part that is not obvious is the last step. Those divisions almost never land on a whole cent, and if you round each person independently the column stops adding up: four people rounding down leave the table short, four rounding up over-tip without meaning to. This calculator works entirely in whole minor units — cents, pence, paise — gives each person the floor of their exact entitlement, and then hands the leftover units out to the largest fractions. It is the same largest-remainder method used to allocate seats from vote shares, and it guarantees the per-person column sums to the grand total precisely, every time.
Tipping before or after tax
This is the question most tip calculators quietly answer for you, usually by applying the percentage to whatever number you typed in. It matters, because tax is not part of the service: nobody served you the sales tax. Applying the percentage to the pre-tax subtotal is the stricter reading, and it is what many people do when they are paying attention. Applying it to the full check is simpler, slightly more generous, and what a card terminal’s suggested amounts normally do on your behalf.
The gap between the two is the tip percentage applied to the tax, which is a percentage of a percentage — small in absolute terms on an ordinary bill, and larger on a big one. The calculator shows you the difference in cash the moment you enter a tax amount, so you can decide with the number in front of you rather than arguing about the principle. Outside places where a percentage tip is customary the question mostly disappears, because the bill already includes service.
One thing worth checking before you calculate anything: whether a service charge is already on the bill. Large tables, tourist areas and many venues outside North America add one automatically. If it is there, the percentage has already been applied — adding another on top is a choice, not an obligation, and it is easy to do by accident when a terminal prompts you after the fact.
When “just divide it by four” is not fair
An even split is the fastest way to end a meal and the most common source of quiet resentment. The person who had soup and tap water is subsidising the person who ordered the steak and a second bottle of wine. Most tip calculators cannot help here at all: they take one bill and one headcount, which is the exact shape of the problem that does not need solving.
Switch this tool to By what each person ordered and you get a row per person. Type what their items came to, before tax, and the bill total is built up from the rows so you can check it against the printed check. Tax follows the items, because tax is charged on what was ordered. The tip is the interesting choice:
- Proportional— the tip is split the same way the food is. Whoever ordered more tips more. This is the default because it keeps each person’s total a consistent multiple of what they ate.
- Even— the food is split by order but the tip is divided equally. The argument for it is that the service was the same for everyone at the table: the same seat, the same attention, the same number of trips from the kitchen.
Neither is more correct. What helps is seeing both: flip the toggle and watch the per-person column move. The difference is usually small enough that the table stops caring, which is the real goal. Split the difference in practice by whichever way makes the smallest bill holder comfortable — the totals differ by less than the price of a coffee on most bills.
Rounding up, and the tip you really left
Asking four people for 23.47 each is a worse experience than asking them for 24. The round-up option takes each person’s share to the next whole unit, or the next five or ten, and the difference goes straight onto the tip. Two rules are enforced so this never quietly goes wrong. First, rounding is applied to each person’s exact entitlement, not to the already-apportioned figure, so nobody can end up paying less than their true share because a stray cent went the other way. Second, the tool recalculates and displays the effective tip percentage afterwards.
That second number is the one nobody checks. Rounding four shares up to the nearest unit adds up to four times as much as it looks. Here is the ladder for an illustrative 100bill — a round number chosen so you can scale it, not a claim about what dinner costs — showing what each percentage produces, the per-person figure for two and four people, and what happens to the real tip percentage once four people round up.
| Tip | Tip amount | Total | Split 2 | Split 4 | 4 rounded up → real tip |
|---|---|---|---|---|---|
| 10% | 10.00 | 110.00 | 55.00 | 27.50 | 28 each → 12.0% |
| 15% | 15.00 | 115.00 | 57.50 | 28.75 | 29 each → 16.0% |
| 18% | 18.00 | 118.00 | 59.00 | 29.50 | 30 each → 20.0% |
| 20% | 20.00 | 120.00 | 60.00 | 30.00 | 30 each → 20.0% |
| 25% | 25.00 | 125.00 | 62.50 | 31.25 | 32 each → 28.0% |
Read the last column carefully. Rounding is a generous habit, and there is nothing wrong with it — but on a small bill split several ways it can push the real tip noticeably past the percentage you chose. If you want a clean number and a specific percentage, round the total once rather than rounding every person, or nudge the percentage down a point before rounding.
Tipping is a local custom, not a global rate
The single most expensive assumption a traveller makes is that the tipping habit they grew up with applies everywhere. It does not. In some countries a percentage tip is part of how hospitality staff are paid; in others service is built into the menu price and a tip is a small courtesy; in a few, offering one is awkward at best. The table below describes the shapeof the custom rather than a number, because the expected amount varies by city, by venue and by whether a service charge is already printed on your bill — and because customs genuinely change. Treat it as orientation, then look at the bill in front of you.
| Where | Shape of the custom | What that means at the table |
|---|---|---|
| United States | Percentage tip expected | Table service, bars and delivery all run on tipping, and card terminals usually suggest several percentages. Large groups often have a service charge added automatically — check before adding more. |
| Canada | Percentage tip expected | Broadly the same as the US in table service, with terminals prompting a choice at payment. Provinces differ on how tips interact with wages, but the customer-facing custom is the percentage tip. |
| United Kingdom | Often already on the bill | A discretionary service charge is commonly added, especially in cities and for larger tables. If it is there, an additional tip is not expected; if it is not, a modest tip or rounding up is normal in table service. |
| Ireland & much of Western Europe | Service usually included | Menu prices generally include service, so tipping is a smaller, optional gesture rather than part of staff pay. Rounding the bill up, or leaving a small amount in cash, is the usual form. |
| France, Germany, Austria, Italy, Spain | Rounding up is usual | Service is normally included in the price. People round up to a convenient figure, or tell the server the total they want to pay when handing over a card. Italy's coperto is a cover charge, not a tip. |
| Australia & New Zealand | Optional, not assumed | Hospitality pay does not depend on tips, so leaving nothing is unremarkable. Tipping happens for genuinely good service, more often in city restaurants than in cafés or pubs. |
| Japan | Not customary | Tipping is not part of the culture and can cause confusion or be politely refused; leaving cash on a table may be returned to you. Some hotels and traditional inns add a service charge instead. |
| China & South Korea | Not customary | Tipping is generally not expected in restaurants. Hotels and venues aimed at international visitors are the exception, and often add a service charge rather than inviting a tip. |
| India | Modest tip, watch the bill | Table service often attracts a small tip. A service charge may be printed on the bill; it is not a government levy and is not mandatory, so read the bill before adding anything on top. |
| UAE & Singapore | Service charge usually added | Bills commonly show a service charge alongside tax, so extra tipping is a courtesy rather than an expectation. Rounding up in cash is the most common gesture. |
Customs shift, and individual venues set their own policies — a service charge on the bill, a no-tipping policy, or a pooled-tips note on the menu all override the general habit. When in doubt, the bill itself is the most reliable source in the room.
Using this at an actual table
The fastest route for the common case: type the bill, tap a percentage chip, set the headcount, done — three interactions and the per-person number is on screen. The currency selector and your usual percentage are remembered on this device, so the second visit is two taps. The bill itself is deliberately not saved; nobody wants last Tuesday’s dinner sitting in the box when they open the page.
For the awkward case — one card paying, everyone transferring their share back — use the per-person mode and read out the Pays column. Because those figures reconcile to the total exactly, the person holding the card is not left covering a shortfall of a few cents, which is the small indignity that makes people stop bothering. Add the round-up option if you would rather ask for whole numbers, and glance at the effective percentage before you commit to it.
A few related tools sit alongside this one. The percentage calculator handles the general case when the number you need is not a tip, the discount calculator does the same job in the other direction, and if the meal out is part of a wider question about where the money goes, the emergency fund calculator takes a longer view. All of them run entirely in your browser.
Frequently asked questions
How much should I tip at a restaurant?
It depends entirely on where you are eating, which is why this calculator lets you set any percentage rather than pushing a “correct” one. In countries where tipping is part of how hospitality staff are paid, table service normally attracts a percentage of the bill and card terminals will suggest a few options. In countries where service is included in menu prices, rounding up or leaving a small amount is the usual gesture, and leaving nothing is not rude. Check the bill first: if a service charge has already been added, the percentage has been applied for you.
Do you tip before or after tax?
Both are done, and the calculator supports either. Tipping on the pre-tax subtotal is the stricter reading, on the grounds that nobody served you the sales tax. Tipping on the full check is simpler and slightly more generous, and it is what a payment terminal’s suggested amounts usually calculate. Enter the tax amount and the tool shows you the cash difference between the two straight away, so you can decide with the actual number in front of you instead of debating the principle.
How do you split a bill when everyone ordered different things?
Switch to the per-person mode, add a row for each person, and enter what their own items came to before tax. The calculator allocates the tax in proportion to what each person ordered, then splits the tip either proportionally or equally — your choice — and shows a per-person total. The bill total is built from the rows, so you can check it against the printed check before anyone pays. Shared items are easiest handled by dividing them between the people who ate them and adding each part to that person’s row.
Should the tip be split evenly or in proportion to what people ordered?
There is no right answer, only two reasonable ones. Proportional splitting says the tip should track the bill, so whoever ordered more tips more. Even splitting says the service was identical for everyone at the table — the same seat, the same attention — so the tip should be identical too. Flip the toggle and compare the per-person column: on most bills the difference between the two is smaller than people expect, which usually ends the discussion faster than arguing about it would.
Does rounding up mean someone pays more than their fair share?
Everyone pays at least their exact share, never less — rounding is applied to each person’s precise entitlement rather than to an already-rounded figure, so a stray cent can never leave the table short. The extra created by rounding goes on top of the tip, and the tool shows both the cash amount and the effective tip percentage afterwards. That second figure is worth a glance: rounding several people up to whole units on a small bill can push the real tip a surprising way past the percentage you selected.
Do the per-person amounts always add up to the bill?
Yes, exactly. Dividing a bill rarely lands on whole cents, and rounding each share independently either loses money or invents it. Every figure here is computed in whole minor units — cents, pence, paise — and the leftover units are allocated by the largest-remainder method, so one or two people may pay a single cent more than the others and the column reconciles to the total precisely. When round-up is switched on, the collected amount is deliberately higher than the bill, and the difference is shown as extra tip.
This page is general information about arithmetic and social custom, not financial advice, and it does not attempt to tell you what a correct tip is in your situation. Tipping norms differ by country, city and venue, change over time, and are overridden by whatever a particular business prints on its bill. Results are only as accurate as the amounts you enter.
