Tip & Bill Splitter

Tipping Etiquette and How Tips Are Calculated

Tipping customs vary significantly by country and service type. In the United States, tipping is expected in most service industries and typically ranges from 15% to 25% of the pre-tax bill. In the UK, 10%–12.5% is common in restaurants; many add a discretionary service charge. In Japan and much of East Asia, tipping is not customary and can be considered rude. This calculator works for any percentage — use local customs as your guide.

Tip on Pre-Tax vs Post-Tax — Which Is Correct?

Technically, tipping on the pre-tax amount is more common and mathematically correct — you are rewarding the service, not the government's tax. In practice, the difference between 20% of pre-tax and 20% of post-tax is small: on a $50 pre-tax bill with 10% sales tax ($55 total), the difference is 20% × $50 = $10.00 vs 20% × $55 = $11.00 — one dollar. Most diners round up and tip on the post-tax total for simplicity. This calculator lets you choose.

How Bill Splitting Works

When splitting evenly, the total bill (including tip) is divided by the number of people. For example: 6 people, $180 bill, 20% tip. Tip = $36. Total = $216. Per person = $36. If people ordered different items and want to split accurately, total each person's order individually, then apply the tip percentage and divide the tax proportionally. This calculator supports even splits up to 50 people.

How Tipping Works — Standard Rates Explained

A tip (or gratuity) is a voluntary payment made to service staff above and beyond the listed price. Tipping customs vary significantly by country, region, and service type.

Recommended Tip Percentages

  • 10–12%: Below average service, or in countries with lower tipping norms
  • 15%: Standard service at a sit-down restaurant — the historical standard in the US
  • 18%: Good service — increasingly common as the new baseline
  • 20%: Excellent service — now considered the standard tip at most US restaurants
  • 25%+: Exceptional service, or tipping for complex or highly personalised service

Standard Tipping Etiquette by Country

  • United States: 18–22% expected at restaurants; 15–20% for taxis; $1–2/drink at bars
  • United Kingdom: 10–12.5% at restaurants (check if service charge is already included)
  • Canada: 15–20% at restaurants, similar to US norms
  • Australia: Tipping not expected but appreciated; 10–15% for exceptional service
  • Japan: Tipping is considered rude — excellent service is a cultural standard, not rewarded with cash
  • Germany/France: Round up the bill or leave a small amount (5–10%), not a percentage

How to Split a Bill Fairly

When splitting a restaurant bill among a group, there are three common approaches:

  1. Equal split: Total bill (including tip) divided equally. Simple but may feel unfair if people ordered very different amounts.
  2. Pay what you ordered: Each person pays for their items plus their share of tax and tip. More accurate but requires itemised receipts.
  3. One person pays, others Venmo: Common approach — use this calculator to work out each person's share before settling up.

Should You Tip on the Pre-Tax or Post-Tax Amount?

Strictly speaking, tipping on the pre-tax subtotal is the traditional etiquette. However, in practice, most people tip on the post-tax total as it is simpler. On a $100 meal with 8% tax, the difference is about $1.60 — negligible in most cases. This calculator lets you tip on whichever base amount you prefer.

Worked example — group dinner: A table of 8 people has a pre-tax bill of £240. They want to leave a 15% tip on the post-tax total (10% sales tax = £24). Tip = 15% of £264 = £39.60. Total with tip = £303.60. Split 8 ways = £37.95 per person. The tip calculator does all of this in one go: enter the bill, select pre-tax or post-tax, pick the tip percentage, enter the number of people, and it shows every figure.

Dining out with friends, ordering delivery, or taking a taxi — the tip calculator removes the awkward mental arithmetic at the end of a meal and ensures everyone pays their fair share. With support for pre-tax or post-tax tipping and even splits for up to 50 people, it covers every group dining scenario.

Whether you are splitting a birthday dinner among 12 friends or calculating a quick 20% tip on a takeaway order, this tool handles the maths so you can focus on enjoying the meal.
