Tip and Split Calculator
Pre-tax or post-tax changes the tip.
Work out Tip and Split. Pre-tax or post-tax changes the tip. Counts the thing everyone forgets to count.
Set to 0 for the exact amount
Each person pays
35.40
141.60 total including 21.60 tip
Rounding each share up leaves a surplus that goes to the server rather than back to the table, which is usually the intention. Splitting a bill evenly when one person ordered far more is a different problem, and it is worth settling before the bill arrives rather than over it.
How the Tip and Split Calculator works
Tip, total and per-person share, with the option to tip on the pre-tax amount and to round each share up. Both tipping conventions are in use and they produce different numbers, so the page asks rather than assuming.

Pre-tax or post-tax, and how much it matters
Tipping on the pre-tax subtotal is the older convention and produces a smaller tip. Tipping on the total as printed is now more common in most places that tip at all. Both are defensible and the difference is roughly the tax rate multiplied by the tip rate.
On a £120 bill including 10% tax at an 18% tip, the pre-tax base is £109.09 and the tip is £19.64 rather than £21.60. Small on one meal; a few pounds a week for anyone who eats out regularly.
The page asks rather than assuming, because the convention differs by country and by generation and there is no correct answer. What matters is knowing which one you are applying rather than discovering later that the number felt wrong.
Splitting when the orders differ
Even splitting is fast and unfair when one person ordered substantially more, and itemised splitting is fair and slow. Neither is wrong; the failure is choosing between them when the bill arrives rather than before ordering.
A common middle ground splits food evenly and drinks separately, which handles the most common asymmetry — one person on tap water and another on three cocktails — without itemising every dish.
Rounding each share up to a convenient amount avoids coins, settles quickly, and sends the surplus to the server. It is a small deliberate over-tip, which is worth stating explicitly so nobody thinks the arithmetic is wrong.
Service charges, and where the money goes
A mandatory service charge is legally distinct from a discretionary tip in most systems. The charge is typically the venue's revenue, which it may or may not distribute; the tip generally belongs to staff. Where a service charge has been added, a further tip is optional.
Cash reaches staff most directly in most venues. Card tips generally run through payroll, which is more transparent and, depending on local rules, may be subject to deductions. Neither is universally better and the difference is worth knowing.
Tipping norms vary enormously between countries — from a substantial expectation to being unusual or mildly awkward. Exporting your own country's convention is a reliable way to get it wrong in both directions.

Frequently asked questions
How do I calculate a tip?
Multiply the bill by the tip percentage. An 18% tip on £120 is £21.60, making £141.60 in total. Whether the percentage applies before or after tax is a convention rather than a rule.
Should I tip on the pre-tax or post-tax amount?
Both are practised. Tipping pre-tax is the older convention and produces a slightly smaller tip; tipping on the total as printed is now more common. The difference is roughly the tax rate times the tip rate.
How much should I tip?
It depends entirely on the country. Tipping norms range from expected and substantial to actively unusual, and in some places service is included by law. Check local practice rather than exporting your own.
Is a service charge the same as a tip?
Usually not. A mandatory service charge is typically the venue's revenue, which they may or may not distribute to staff; a discretionary tip generally belongs to staff. Where a service charge appears, adding a tip on top is optional.
How do we split a bill fairly when orders differ?
Itemised splitting is fairest and slowest; even splitting is fastest and unfair where one person ordered far more. Agreeing which before ordering avoids the awkward version of the conversation.
Do I tip on a discounted bill?
Convention is to tip on the pre-discount amount, since the service was the same. It is a courtesy rather than an obligation and views differ.
What is a service charge and can I remove it?
A charge added by the venue, sometimes described as discretionary. Where it is genuinely discretionary you can usually ask for it to be removed; where it is stated as mandatory, generally not.
Should I tip in cash or on the card?
Cash reaches staff directly in most venues. Card tips usually go through payroll, which is more transparent and sometimes subject to deductions depending on local rules.
How do we split when one person had far more?
Itemised splitting is fairest, and agreeing the approach before ordering avoids the awkward version of the conversation. Splitting drinks separately from food is a common middle ground.
Is tipping expected everywhere?
No, and in some countries it is unusual or mildly awkward. Norms range from a substantial expected percentage to nothing at all, so check local practice rather than exporting your own.
What is a fair tip for a large group?
Many venues add a mandatory service charge for large groups, which should be stated on the menu. Where it has been added, adding a further tip on top is optional.
