What this calculator solves
Price the incremental work of grouping finished items into one sellable or shippable bundle. The result combines per-item handling, bundle-specific materials, and packing labor on a per-bundle basis. It does not include the underlying product cost.
How to choose the inputs
Count items in the bundle, establish handling cost per item from the chosen cost method, enter only materials unique to bundling, and time the bundling action separately from final order packing. Use one currency basis throughout.
| Input | How to prepare it |
|---|---|
| Items per bundle | Enter the number of finished items grouped into one bundle; use the same bundle configuration as the timed work. |
| Handling cost per item | Enter the incremental handling cost for one item, excluding the product value and any handling already included in another cost line. |
| Bundle materials | Enter the material cost used once per bundle, such as a band, bag, label, or insert; exclude final shipment packaging counted elsewhere. |
| Packing minutes | Time the repeatable handling and packing work for one bundle, excluding one-time setup, breaks, exceptions, and final order packing unless those are intentionally included. |
| Hourly labor rate | Use either a documented direct or loaded hourly labor rate consistently; the calculator converts this rate to labor cost for the entered minutes. |
How the calculation works
- Calculate item handling: multiply items per bundle by the handling cost for one item.
- Calculate packing labor: divide packing minutes by 60 and multiply by the hourly labor rate.
- Calculate cost per bundle: add item handling, bundle materials, and packing labor, then review those three subtotals before applying the per-bundle result to a planned batch quantity.
Worked example
Four items at $0.18 handling, $0.55 materials, and three minutes at $18/hour cost $2.17 per bundle.
Next action: Add final order-level packaging, multiply the per-bundle result by the planned bundle quantity for a batch or monthly budget, and compare it with the separate-item method.
How to interpret the result
Use the three subtotals to see whether item handling, bundle materials, or packing labor drives the cost per bundle. Packing labor equals packing minutes divided by 60, multiplied by the hourly labor rate. For a batch budget, multiply the displayed per-bundle total and labor subtotal by the planned number of bundles outside this tool, then compare that total with the separate-item method.
Common mistakes
- Including the full product cost as handling cost by accident.
- Counting final shipment packaging in both bundle materials and order packaging.
- Using assembly time from a different bundle size.
- Ignoring extra labels, bands, or inserts unique to the bundle.
Assumptions and limitations
The model assumes identical handling cost per item and a fixed bundle method. It excludes product cost, final shipping container, picking travel, inventory risk, equipment, errors, returns, and promotional pricing.
