What's a standard tip percentage?

15-20% is common in the US for restaurant service, though customs vary significantly by country and type of service — check local norms if you're unsure what's expected.

How is the per-person amount calculated?

The total bill including tip is divided evenly by the number of people splitting — for an uneven split based on what each person ordered, you'd need to calculate individual shares separately before applying the tip.

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

Conventions vary — many people tip on the pre-tax subtotal, though tipping on the full post-tax total is also common. Either way, decide on a consistent convention and apply it to the bill amount you enter.

Does this work for splitting a bill unevenly?

This calculator splits evenly across the number of people entered. For an uneven split based on individual orders, calculate each person's subtotal separately, then apply the same tip percentage to each share.
