Understanding Your Results
Bag and bin dimensions help identify the correct liner but do not prove fit. Count loose bags separately from complete rolls.
The quantity beside the item name is the stock value used for LOW STOCK: quantity at or below your minimum triggers that status. Additional days, cycles, sets or dates describe the entered assumptions; they are not a live measurement. Recount after use, receipt or relocation. A different device reads the printed snapshot and does not automatically receive later inventory changes.
The recorded dimensions still need checking against the actual bin.
Practical Examples
These are illustrative household inputs, not product specifications or recommended use rates. Enter each record below, select Calculate & Save, and compare the displayed calculation.
Count full trash-bag rolls and loose bags
The kitchen supply contains three rolls plus five loose liners.
Count loose bags outside the full rolls separately.
Inputs: Remaining rolls: 3; Bags per roll: 20; Loose bags: 5; Bag and bin dimensions: 50 × 60 cm; kitchen bin.
Result: 3 × 20 + 5 = 65 bags Saved quantity: 65 bags.
The result is sixty-five individual bags.
The recorded dimensions still need checking against the actual bin.

Two bin sizes use different bag specifications.
Create format-specific records rather than one mixed roll total.
Inputs — record 1: Remaining rolls: 2; Bags per roll: 30; Loose bags: 4; Bag and bin dimensions: 35 × 45 cm; bathroom bin.
Result: 2 × 30 + 4 = 64 bags Saved quantity: 64 bags.
Inputs — record 2: Remaining rolls: 1; Bags per roll: 20; Loose bags: 3; Bag and bin dimensions: 50 × 60 cm; kitchen bin.
Result: 1 × 20 + 3 = 23 bags Saved quantity: 23 bags.
Sixty-four bathroom bags and twenty-three kitchen bags remain distinguishable.
Bag capacity and rim fit are not inferred from these example dimensions.

A household wants a warning at twenty available liners.
Save the physical remainder and select Only low stock.
Inputs: Remaining rolls: 0; Bags per roll: 20; Loose bags: 18; Bag and bin dimensions: 50 x 60 cm; kitchen bin.
Result: 0 × 20 + 18 = 18 bags Saved quantity: 18 bags.
Eighteen bags are below the twenty-bag threshold.
The filter is not a daily-use forecast.

Entering six as bags per roll would alter the product specification. The stock increases by ninety bags. Use a new record if the delivery has a different roll size.
Entering one full roll plus twelve loose bags would duplicate its contents. Twelve available liners are recorded without pretending the roll is full. The form does not estimate bags from roll diameter.
Do not leave the transferred bags counted at both locations. The cupboard decreases by ten; the household total need not decrease. Location transfers require two explicit record updates.
How do I allocate liners to a moving-day bin?
Reduce the cupboard remainder and create a kit record for the ten moved bags. The cupboard decreases by ten; the household total need not decrease.
Location transfers require two explicit record updates.
How do I record a completely depleted liner supply?
Keep the purchasing specification while setting both stock components to zero. The record shows zero bags and enters the low-stock view.
A zero record can be retained as a shopping reference.
How do I avoid treating bag dimensions as a stock calculation?
Record the measured specification alongside the count. Twenty bags are available, while the fit question remains a physical check.
Check the bin rim and tie allowance separately.
How do I correct a count after discovering an empty roll?
Remove that roll from full stock without altering loose bags. The correction subtracts exactly twenty liners.
Verify that the remaining counted rolls are genuinely full.
How do I update the liner label after a roll is opened?
Save both component changes together and rebuild the label. The total stays forty bags while the packaging state becomes accurate.
Recount loose bags after actual use.
