How to Use This Calculator
  1. Enter Garden Sq Ft to estimate total harvest volume and the corresponding preservation workload.
  2. Input Canning Jars Available and Freezer Cu Ft to match preservation methods to available equipment.
  3. Enter Dehydrator Trays and Family Size — larger families consume more and benefit from larger batches.
  4. Review Canning Days to plan water-bath and pressure canning sessions around peak harvest weeks.
  5. Check Freezing Batches and Dehydrating Batches to schedule processing across the fall preservation season.
  6. Use Total Processing Days and Average Shelf Life to build a preservation calendar and pantry inventory plan.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Garden Size = 2000, Canning Jars Available = 120, Freezer Capacity = 15, Dehydrator Trays = 9 = 5 input(s) provided
  2. Calculate Canning Days
    Canning Days
    6 = 6
  3. Calculate Total Processing Days
    Total Processing Days
    33 = 33
  4. Calculate Freezing Batches
    Freezing Batches
    27 = 27
  5. Calculate Dehydrating Batches
    Dehydrating Batches = max(0
    20 = 20
