How to Use This Calculator
  1. Enter the number of meals needed at peak per hour.
  2. Set the average cook time in minutes and the oven type (convection, combi, deck, conveyor, or rotisserie).
  3. Enter the number of portions that fit per pan.
  4. Review the number of ovens needed and peak utilization to avoid over- or under-buying.
  5. Check total BTU and floor space requirements for utility and layout planning.

What each input means

Meals Needed at Peak (per hr)
Number of oven-cooked portions needed per hour during peak service.
Avg Cook Time (min)
Average cooking time per batch in minutes.
Oven Type
1 = Convection, 2 = Combi (steam+convection), 3 = Deck/Pizza, 4 = Conveyor, 5 = Rotisserie.
Portions per Pan
Number of individual portions that fit on one full-size sheet pan (not used for conveyor ovens).

What each result means

Ovens Needed
Number of ovens required to meet peak demand.
Portions/Hr per Oven
Production capacity of each oven per hour.
Total Capacity/Hr
Combined hourly output of all ovens.
Peak Utilization (%)
How much of total oven capacity is used at peak.
Total BTU (gas)
Combined gas BTU rating for all ovens.
Floor Space (sq ft)
Approximate floor space needed for all ovens.
Oven Turns/Hr
How many cook cycles fit in one hour.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Meals Needed at Peak (per hr) = 60, Avg Cook Time (min) = 25, Oven Type = 1, Portions per Pan = 8 = 4 input(s) provided
  2. Calculate Ovens Needed
    1 = 1
  3. Calculate Portions/Hr per Oven
    154 = 154
  4. Calculate Total Capacity/Hr
    154 = 154
