Create your own packaging cost calculation sheet
The key elements of the cost calculation sheet are the wear-and-tear rate and mold amortization; most disputes over quotations arise from these two items.

Sources of a two-fold price difference
Create your own cost accounting sheet; this will give you a clearer picture of where your money is being spent than repeatedly asking for quotes. The sheet doesn't need to be complicated—five items are enough.
misread:The more complex the accounting statement, the more accurate it is.Actual circumstances:Complexity does not equate to accuracy; if two key parameters are estimated incorrectly, the entire table will be skewed.
There is also a common misconception:The more complex the accounting statement, the more accurate it is.In fact:There are only two key parameters: the wear rate and mold amortization.
Basis for Determination
Single-material cost (unfolded area × grammage × paper price + waste rate); process labor hours (unit cost or labor hours per process × rate); waste rate (varies for printing, die-cutting, and manual processing); mold amortization (one-time cost divided by batch size); logistics and taxes.
- Single material item
- Process labor hours
- attrition rate
- Mold amortization
Accounting sequence
The value of this table lies in its ability to modify parameters: change the box type, adjust the grammage, or alter the batch size—costs change instantly. Using it for solution comparison and selection is far faster than waiting for a factory quote.
- The loss rate should be categorized by process and batch size; do not apply a single figure universally.
- Mold amortization should be calculated based on the expected order volume, rather than per production batch.
- Calibrate the parameters once per quarter using actual data.
- Leave a column titled "Actual Value" in the accounting sheet and populate it using historical orders.
Applicability: For one-off projects, detailed cost accounting is unnecessary; historical data from similar projects may be used for estimation.
On-site settings and practices we have observed
Two suppliers quote the same box: one states a loss rate of 3%, while the other states 8%. The difference is five percentage points, resulting in a difference of 0.4 yuan in unit price. When asked for clarification, one supplier estimates based on ideal conditions, while the other bases their estimate on actual conditions, including the installation of the control system and defective items. Which one is correct? It depends on the batch size and the complexity of the process; there is no one-size-fits-all answer.
The INNOPACKING accounting sheet will list wear and amortization separately and adjust them according to the actual circumstances of each project. Data from previous orders will be carried forward, making the next estimate more accurate. Accounting is an experience-based activity, but experience should be quantified into numerical data. Include a column in the sheet for actual values; once three orders have been processed, the data can be calibrated, which is far more reliable than making estimates based on intuition. Build the accounting sheet by project rather than creating a single comprehensive table; with too many projects, the sheet becomes cluttered and will have no one to maintain it.

What are the key considerations for a cost accounting statement?
Downtime rate and mold amortization. If these two items are estimated incorrectly, the entire table will be skewed.
How should the loss rate be determined?
Categorize by process and batch size; do not rely on a single figure for all cases. Calibrate using the actual values from historical orders.
Should the cost statement be provided to the supplier?
You don't need to provide the full amount, but you can provide the framework so that the other party can quote prices based on the same basis.
