Tip calculator is a calculator tool that splits a restaurant bill across any number of guests with a custom tip percentage. It supports common presets, custom rates, and an optional round-up for easier cash payment, and shows per-person and total figures. The tool runs in your browser.
Frequently asked questions
- What tip percentage should I leave?
- Common guidelines vary by location. In the UK, 10–15% is typical for table service. In the US, 15–20% is standard with 18–20% common in most restaurants. This calculator accepts any value from 0 to 100.
- How does the per-person split work?
- The total bill plus tip is divided equally by the number of guests. Each person's tip share and total share are shown separately so you can see both the tip contribution and the full amount each person owes.
- What does the round-up option do?
- The round-up option applies Math.ceil() to each person's total, rounding up to the nearest whole number. This makes cash splitting easier and slightly increases the tip amount.
