What This Calculator Measures

Estimate pantry calorie reserves using daily needs, spoilage, and restock plans.

By combining practical inputs into a structured model, this calculator helps you move from vague estimation to clear planning actions you can execute consistently.

This calculator estimates pantry calorie reserves and coverage.

How to Use This Well

  1. Enter pantry and daily calories.
  2. Add reserve days and spoilage.
  3. Include restock calories.
  4. Review days covered.
  5. Adjust stock levels.

Formula Breakdown

Usable = (pantry + restock) x (1 - spoilage)
Days: usable / daily calories.
Portions: usable / portion calories.
Reserve: daily x target days.

Worked Example

  • 18,000 + 6,000 = 24,000 kcal.
  • After 8% spoilage = 22,080 kcal.
  • About 10 days at 2,200 kcal.
