FAQ

Is this for a full meal?

The appetizer number assumes heavy passed food. If you're serving a seated meal, cut the appetizer count roughly in half.

Should I round up?

Round up on ice and drinks, round to the nearest package on food. Leftover ice costs pennies; running out mid-party doesn't.

Accuracy and limitations

  • Estimates assume standard, average conditions — local rules, pricing, and materials vary.
  • Results are rounded for readability; add a buffer before ordering, booking, or committing.
  • Double-check anything with a real cost attached against a local quote.
