What this tool does
An exact split usually produces awkward amounts with cents, so the second result rounds each share up to the nearest step you choose. The third shows the surplus that rounding creates, which normally becomes the tip.
Formula
per person = (total + extras) ÷ people

- The tool works with whatever currency you use for the inputs; it does not convert between currencies.
- The calculation runs at full precision and only the display is rounded. If you copy an intermediate value and retype it, small differences can appear.
