Quick answer: Tip Calculator
UK tipping is optional, with 10-15% common in restaurants when service charge is not already included. US restaurants commonly expect 18-22%.
Example: On a GBP 85 restaurant bill for 4 people, a 12.5% tip is GBP 10.63 total, making the split about GBP 23.91 per person.
Calculations follow the documented formula on this page; rounding and input units can change the last digit—treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
What this calculator does
- Tip Calculator
- Calculate tip, total bill, and per-person split.
Check whether service charge is already included before adding more. Split bills after adding tip when the group shares evenly.
Work out restaurant tips and split the total fairly across a group.
Inputs on this page: Bill Amount, Tip (%), People. Assumptions stay visible so you can reproduce the figure elsewhere.
When to use it
- Use Tip Calculator when you need a transparent tip calculator answer before you commit numbers to a spreadsheet, invoice, or conversation.
- Reach for it when you already know (or can estimate) Bill Amount and want the dependent result without rebuilding the formula by hand.
- Skip it when you need certified advice, signed-off payroll, or a lender’s official quote—those require the primary institution’s systems.
Key takeaways
- Do not double-tip when a discretionary service charge is already on the bill.
- US vs UK norms differ—match the local expectation, not a single global %.
- For uneven splits, allocate tip proportional to each person’s share of the food total.

How the calculation works
The Formula
Tip = Bill × (Tip%/100); Per person = (Bill + Tip) ÷ Party size- Bill Amount: the value you enter for bill.
- Tip (%): the value you enter for tip.
- People: the value you enter for people.

Common mistakes
- Adding a tip on top of an included service charge can double-tip accidentally. Check the bill for service charge or discretionary gratuity before adding more.
- Assuming UK and US tipping norms are the same can create awkward totals. UK tipping is optional in many settings, while US restaurant tipping is expected at a higher percentage.
- Splitting the bill before adding the tip can understate each person's share. Add tip to the full bill first, then divide by the number of people.
