How the calculation works

The tip is the bill amount multiplied by the tip percentage divided by 100. The total adds the tip to the bill. The per-person figure divides that total by the whole-number party size.

Conventions and boundaries

  • Rate: you choose the tip percentage; the calculator does not recommend a rate.
  • Split: the per-person result is an equal mathematical split and does not allocate rounding differences among diners.
  • Amount: results use the same currency units as the bill amount, without exchange-rate or tax assumptions.
  • Scope: service charges, taxes, local customs, and non-equal shares are outside scope.

Common questions

Does the calculator choose the tip rate?

No. The rate is entirely user-entered. The tool performs arithmetic on that choice.

Can I split the total?

Yes. Enter a whole-number party size to see the equal share of the total.
