Tip & Bill Split Calculator
Split a bill, work out the tip, and handle uneven shares by country.
What it does. A tip calculator works out the gratuity on a bill and divides the total between diners. This one carries tipping norms for the US, Canada, the UK, Europe and the Gulf, handles uneven splits, and can round each share to a convenient amount so nobody is chasing small change.

How to use Tip & Bill Split Calculator
- Enter the bill total and how many people are sharing it.
- Pick your country for the customary rate, or set a percentage yourself.
- Read each person’s share. Use uneven mode if some people are paying more.
What is customary where
Tipping norms vary more than almost any other social convention, and getting it wrong is either expensive or awkward. These are the current expectations in restaurants with table service.
| Country | Restaurant | Service charge included? | Notes |
|---|---|---|---|
| United States | 18–22% | Rarely | Staff wages assume tips; under 15% signals a complaint |
| Canada | 15–20% | Rarely | Similar to the US; slightly lower is normal |
| United Kingdom | 10–15% | Often 12.5% | If a service charge is on the bill, nothing more is expected |
| Ireland | 10–15% | Sometimes | Check the bill before adding |
| France | 0–5% | Yes, by law | "Service compris" — rounding up is generous |
| Germany / Austria | 5–10% | No | Round up and state the total when paying |
| Italy / Spain | 0–10% | "Coperto" is a cover charge, not service | Small tip appreciated, not expected |
| Netherlands / Belgium | 5–10% | Usually | Rounding up is the norm |
| Nordics | 0–10% | Yes | Tipping genuinely optional |
| UAE / Saudi / Qatar | 10–15% | Often 10% | Service charge frequently added; extra cash appreciated |
| Japan | 0% | No | Tipping can cause offence |
| Australia / NZ | 0–10% | No | Optional, for good service |
Tip on the pre-tax or post-tax total?
Pre-tax is technically correct and post-tax is what most people do.
The argument for pre-tax is straightforward: tax is not part of the service, so tipping on it means tipping the government. In the US the difference is meaningful — on a $100 pre-tax bill in Chicago at 10.25% tax, a 20% tip is $20 pre-tax or $22.05 post-tax.
In practice the difference is small enough that most people tip on the total and do not think about it. This calculator lets you set the tax rate and choose which base to use, and shows both figures so the choice is explicit rather than accidental.
In VAT countries the question mostly disappears, because prices are displayed VAT-inclusive and there is no separate line to reason about.
Splitting a bill without arithmetic arguments
Three modes cover essentially every real situation.
Even split. Total divided by headcount. Simplest, and fine when everyone ate similarly.
By share. Assign a weight to each person — someone who had two courses and wine takes a larger share than someone who had a salad. The tool distributes tip and tax proportionally, which is fairer than adding a flat tip to individual items.
By item. Enter what each person had and let tax and tip distribute proportionally across the whole. This is the accurate one, and the one worth using when the spread is wide.
The rounding control exists because the exact answer is usually £23.47 each, and nobody wants to settle that. Round each share up to the nearest whole unit and the small surplus goes to the tip — which is what happens informally anyway.
What about the service charge already on the bill?
If a service charge is listed, that is the tip. Adding a further 15% on top is double-tipping, and it is common among visitors to the UK and the Gulf where the charge is often applied automatically.
In the UK a discretionary service charge can be removed on request, and since the Employment (Allocation of Tips) Act 2023 came into force, employers must pass tips and service charges to staff in full. That has removed the older concern that a card tip might not reach the server.
In the US, a mandatory service charge on a large party is legally distinct from a tip and may be treated as restaurant revenue rather than the server’s. If the bill shows a mandatory gratuity for a group, an additional tip is optional — but worth asking about, because in some establishments the server sees none of it.
Frequently asked questions
How much should I tip in the US?
18–22% at a sit-down restaurant, 15% for counter service if you tip at all. US tipped wages are set on the assumption that tips make up the difference, which is why the expectation is higher than elsewhere.
Do I tip in the UK?
10–15% is normal, but check the bill first — a 12.5% service charge is frequently already added, in which case nothing further is expected.
Should I tip on tax?
Technically no, and most people do anyway. The tool shows both figures so you can decide rather than default.
Do I tip in the Gulf states?
10–15% is appreciated. A service charge is often added in hotels and larger restaurants; cash directly to the server is common practice on top.
What if a service charge is already on the bill?
That is the tip. Adding more on top is double-tipping. In the UK a discretionary charge can be removed on request.
How do I split a bill unevenly?
Use share or item mode. Tax and tip distribute proportionally, which is fairer than each person adding a flat tip to their own items.
Is anything sent to a server?
No. The arithmetic runs in this page.
