HOW IT WORKS
A result to understand, not just read.
Bag duration depends on the net weight of the pack and the amount actually served each day. Convert kilograms to grams, divide by the total daily portion and add a reorder margin.
FREQUENTLY ASKED QUESTIONS
What if I feed more than one pet?+
Add all daily portions together before entering the total amount used per day.
Is the largest bag always best value?+
Not if the food loses freshness before it can be used. Storage instructions and the manufacturer’s after-opening guidance still matter.
RESULT GUIDE
How to calculate how long a kibble bag will last
The pack weight is converted into grams and divided by the real daily amount used. Monthly consumption and a suggested reorder point then make stock planning easier.
Example: a 12 kg bag
- pack: 12 kg = 12,000 g
- daily portion: 120 g
With a seven-day safety margin, schedule the next order at around day 93.
How to interpret the result
- Use the amount actually served, especially when treats or wet food replace part of the ration.
- Monthly consumption lets you compare pack sizes rather than looking only at the price per bag.
What the estimate does not include
- It does not allow for waste, diet transitions or future portion changes.
- Storage and after-opening shelf life must follow the manufacturer’s instructions.
