About Buffet Line Throughput Calculator

Service time is guests times seconds each divided by the number of parallel lines, and the lines needed divides the total service seconds by the target window. Double-sided buffet tables halve the service time at no extra food cost, which is the cheapest fix for a queue that eats into the schedule.

Formula

Service time

minutes = guests x seconds per guest / (lines x 60)

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
