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.

Technical specification

Algorithm or formula: Tip amount = bill * (tipPercent / 100). Grand total = bill + tip. Per-person share = total / guests. Round-up option applies Math.ceil() to each per-person figure.
Browser API or library: Pure JavaScript arithmetic; no external library.
Input limits: Bill above 0. Tip percent 0–100. Guests 1–20.
Output: Tip amount, grand total, tip per person, and total per person. Updates instantly as you adjust any field.
Known limitations: Equal-split only; no per-item or per-person bill breakdown. Round-up increases the effective tip percentage slightly to balance the cash.
