Tip calculator and bill splitter
A quick way to add a tip, split a restaurant bill between friends, and settle up without doing mental arithmetic at the table. Useful for diners, group meals and anyone who wants a clean per-person figure including gratuity. Supports GBP, USD, EUR, AUD and CAD.
The maths behind the split
The tip is the bill multiplied by the tip percentage: tip = bill × (tipPct ÷ 100). The total is bill + tip. If you tick round up, the total is rounded up to the next whole currency unit, and the displayed tip is recalculated as total − bill so everything reconciles. The per-person amount is the final total divided by the number of people. Preset buttons fill in 10%, 12.5%, 15%, 18% and 20% instantly.
Worked examples
Simple tip. A £60 bill with a 15% tip: 60 × 0.15 = £9 tip, total £69. Three people: 69 ÷ 3 = £23.00 each.
Round-up. A £63.40 bill with a 15% tip gives a total of £72.91. Tick round-up and it becomes £73.00; each of three people pays £24.33 — a cleaner figure to hand over in cash.
| Bill | Tip % | Total | Per person (×3) |
|---|---|---|---|
| £40 | 10% | £44.00 | £14.67 |
| £60 | 15% | £69.00 | £23.00 |
| £80 | 18% | £94.40 | £31.47 |
| £100 | 20% | £120.00 | £40.00 |
Tipping customs by country
Knowing the local norm helps when you are travelling or dining at an international restaurant:
- United States: 15–20% is standard for table service; 18% is common for adequate service, 20%+ for good, and some restaurants add an automatic gratuity for groups of six or more.
- United Kingdom: 10–12.5% is conventional; many restaurants already add a “discretionary service charge” to the bill, so check before tipping on top.
- France and much of Europe: service is typically included (service compris) and rounding up a few euros is all that is expected. Anything more is appreciated but not customary.
- Japan: tipping is generally not expected and can sometimes be considered rude; exceptional service is the norm and no gratuity is expected.
- Canada: similar to the US, 15–18% is standard; many card readers now suggest 18%, 20% or 22% as defaults.
- Australia: tipping is optional — 10% for good service is appreciated but not obligatory, and “no tip” is never awkward.
Should you tip on the pre-tax or post-tax amount?
There is no universal rule. In the US, some people tip on the pre-tax subtotal; others tip on the total after tax. The difference on a typical restaurant bill is small — perhaps a dollar on a £60 meal. This tool tips on whatever amount you enter, so enter the subtotal if you want pre-tax tipping, or the full taxed total if you prefer to tip on the complete amount.
Shareable link
When you are done, copy the shareable link — your inputs travel in the URL (after the #) so the whole table sees the same numbers without needing to recalculate. No data is sent to a server; the values live only in the URL you share.
Tips, service charges and the law — two systems worth knowing
United States: federal law allows a tipped minimum wage of $2.13/hour provided tips bring the worker to the standard minimum — the “tip credit” documented by the U.S. Department of Labor. Several states (California, Washington and others) prohibit the credit and require the full minimum before tips. This is the structural reason tipping percentages are materially higher in the US: for many workers the tip is the wage.
United Kingdom: since the Employment (Allocation of Tips) Act 2023 came into force in October 2024, employers must pass 100% of tips and service charges to workers without deductions, under a written policy — see the GOV.UK guidance on tips at work. A discretionary service charge added to a UK bill is therefore no longer a reason to assume the staff see none of it, though you may always ask.
Rounding strategies that keep the split fair
When a split produces awkward pennies, three clean approaches: round each person’s share up to the nearest major unit and let the excess raise the tip; have one person absorb the remainder (rotate who, among friends who dine together often); or split unevenly by what each person ordered when the bill is lopsided — the calculator’s per-person figure is the even-split baseline to negotiate from. For business meals, note that many expense policies cap reimbursable tips at a fixed percentage; check before generosity exceeds policy.
