A tip calculator computes the tip amount based on the bill total and a chosen tip percentage, then divides the total (bill + tip) equally among the number of people in the group. It is useful at restaurants, for delivery orders and any situation where a service gratuity is expected.

1. Enter the total bill amount.
2. Enter the tip percentage (common values: 10%, 15%, 18%, 20%).
3. Enter the number of people splitting the bill.
4. Click Calculate.

Bill: $85, tip: 15%, 4 people.
Tip: $85 × 0.15 = $12.75 | Total: $97.75 | Per person: $24.44

Tipping customs vary by country and context. In the US, 15–20% is standard for restaurant service. In the UK, 10–12.5% is common. In many other countries, tipping is optional or not customary. Always check if a service charge has already been added to the bill before adding a tip.

• Tipping on a bill that already includes a service charge — check before adding more.
• Calculating tip on the pre-tax amount vs the total — conventions vary; most people tip on the pre-tax subtotal.

Should I tip on the pre-tax or post-tax amount?

Convention varies. In the US, many people tip on the pre-tax subtotal. Others tip on the total including tax. The difference is small — use whichever you prefer.

What is a standard tip percentage?

In the US: 15% for adequate service, 18–20% for good service, 25%+ for exceptional service. In the UK: 10–12.5%. In Australia: tipping is optional and not expected.
