The math behind the result.
Tip = tip base × tip rate; per person = (bill + tip) ÷ party sizeよくある質問
Useful before you decide.
Should I tip before or after tax?
Practices differ. The selector lets you calculate either way so the chosen basis is transparent.
How should a group split uneven orders?
This tool makes an equal split. If spending varies widely, calculate each person's items first and split only shared items, tax, and tip.
What does round up do?
It raises the total to the next whole currency unit, then divides that rounded total across the group.
