Should I tip on the total before or after VAT?

In the UK, it is customary to tip on the total bill amount including VAT. The tip percentage is typically applied to the final figure shown on the bill.

How do I split a tip between multiple people?

Divide the total bill plus tip equally among all diners, or calculate each person's share of what they ordered and add the tip percentage to each individual amount.

Is tipping mandatory in the UK?

Tipping is not mandatory in the UK but is considered good etiquette for table service in restaurants. You are not obliged to pay a discretionary service charge if the service was poor.

How much should I tip a taxi driver in the UK?

For UK taxi drivers, rounding up to the nearest pound is common, or tipping around 10% for longer journeys. Most passengers simply tell the driver to keep the change.

Method & assumptions

This calculator works out a suggested tip amount based on the bill total and your chosen percentage, then optionally splits the final amount — including the tip — across a number of people. Tip percentages are applied to the gross bill as displayed, which in the UK already includes 20% VAT. The split calculation assumes an equal division; if diners ordered very different amounts, you may prefer to use the bill splitter tool instead. The calculator does not automatically detect whether a service charge has already been added to your bill — always check before entering your total. Tipping customs vary by venue type, so the percentage selector lets you adjust to suit a café, restaurant, or hotel dining room.

Common mistakes

Using optimistic assumptions without testing a more cautious scenario.
Comparing outputs from different tools without checking that the inputs match.
Treating the result as a final quote instead of a planning estimate.
Rounding inputs too aggressively.

What to do next

Try at least one more scenario so you can compare a realistic range.
Use the related calculators below to cross-check the decision from another angle.
Write down the key outputs from your best scenarios before you decide.
If the result surprises you, change one input at a time to isolate the driver.
