Tip Calculator

What is Tip Calculator?
A tip calculator quickly determines tip amounts and per-person costs for dining out. It handles the common mental math challenges: calculating 15%, 18%, or 20% of a bill, splitting the total among multiple people, and accounting for tax-included or tax-excluded totals. In cultures where tipping is customary, this tool eliminates the awkward moment of doing mental arithmetic under social pressure, ensuring fair compensation for service while splitting costs evenly among dining companions.
How It Works
Enter the bill total, select a tip percentage (or enter a custom amount), and optionally specify the number of people to split between. The tool calculates: tip amount = bill × (percentage/100), total with tip = bill + tip amount, and per-person cost = total / number of people. It can also round up to a convenient number for easier payment. The tool shows multiple tip percentages side by side so you can quickly compare options and choose the appropriate amount.

Frequently Asked Questions
What's a standard tip percentage?▼
In the US, 15-20% is standard for restaurants. 18% is common for groups.
How much should I tip?▼
It depends entirely on the country. In the United States 15 to 20% is expected for table service and is a substantial part of staff income. Much of Europe includes service and rounding up or adding 5 to 10% is generous. In Japan tipping is not customary and can cause discomfort. Check local norms rather than applying a single habit everywhere.
Should I tip on the pre-tax or post-tax total?▼
Convention in the US is to tip on the pre-tax subtotal, since the tax is not part of the service. Tipping on the post-tax figure is common and simply slightly more generous — on a 20% tip with 8% sales tax the difference is under 2% of the bill.
How do I split a bill unevenly?▼
Total each person's own items, then apply the same tip percentage and their proportional share of tax to each. Splitting the tip equally while splitting the food by item is a common source of disagreement, so agree the method before the bill arrives.
What is a quick way to work out 20% in my head?▼
Move the decimal point one place left to get 10%, then double it. For a £43.60 bill, 10% is £4.36 and 20% is £8.72. For 15%, take the 10% figure and add half of it.
