Frequently Asked Questions

Does it support currencies other than USD?

No. The calculator formats everything in US dollars. The math works for any currency—just ignore the dollar sign—but the output labels are USD-specific.

What is the standard tip percentage in the US?

15-20% for sit-down restaurants is the widely accepted range. 20% has become the practical default in most cities. The calculator pre-populates 15%, 18%, and 20% options, plus a custom field for any amount.
