This chart compares the depletable base, cumulative depletion, and remaining value.
Example Data Table
| Scenario | Acquisition | Development | Restoration | Salvage | Recoverable Units | Current Units | Cost Per Unit |
|---|---|---|---|---|---|---|---|
| Premium mineral stock | $50,000.00 | $10,000.00 | $5,000.00 | $8,000.00 | 19,000 | 2,500 | $3.00 |
| Organic salt reserve | $35,000.00 | $7,500.00 | $4,000.00 | $6,500.00 | 16,000 | 2,000 | $2.50 |
| Stone craft material | $28,000.00 | $6,000.00 | $3,500.00 | $5,500.00 | 12,000 | 1,800 | $2.67 |
Formula Used
Depletable Base = Acquisition Cost + Development Cost + Restoration Cost − Salvage Value
Depletion Cost Per Unit = Depletable Base ÷ Estimated Recoverable Units
Current Period Expense = Depletion Cost Per Unit × Current Units Sold or Used
Remaining Depletable Value = Depletable Base − Cumulative Depletion
This method helps ecommerce teams assign source depletion cost to each unit sold. It is useful when products depend on mined, harvested, or extracted inventory.

Frequently Asked Questions
1. What does depletion cost per unit mean?
It is the allocated depletion expense for each recoverable unit. It spreads the depletable asset base across expected usable units.
2. Why would an ecommerce business use this calculator?
Some ecommerce sellers source products from extractive or harvested assets. This calculator helps price inventory correctly and monitor remaining asset value.
3. What costs belong in the capitalized base?
Include acquisition, development, and restoration costs tied to obtaining usable inventory. Exclude unrelated selling, marketing, and general office expenses.
4. What is salvage value in this model?
Salvage value is the estimated residual amount expected after the asset is depleted. It reduces the total amount available for depletion.
5. What happens if recoverable units change later?
You should recalculate using the updated estimate. Revised unit expectations can change the depletion rate and future period expense.
6. Can I use sold units instead of produced units?
Yes, when your business recognizes depletion with units sold or consumed. Use the measure that matches your internal accounting policy.
7. Why track prior depleted units?
Prior units help calculate cumulative depletion and remaining value. This makes trend tracking and reporting far more accurate.
8. Do exports include the calculator results?
Yes. The CSV and PDF downloads capture the key inputs and calculated outputs, making documentation and sharing much easier.
