What is the Depletion Method?

Depletion is a regular charge to price for the use of natural resources. Thus, that is used in instances where a company has videotaped an asset for such items together oil reserves, coal deposits, or gravel pits. The calculation of depletion requires these steps:

Compute a depletion base

Compute a unit depletion rate

Charge depletion based upon units the usage

The resulting net moving amount of organic resources quiet on the books of a company do no necessarily reflect the industry value that the underlying natural resources. Rather, the amount just reflects an recurring reduction in the amount of the original recorded expense of the herbal resources.

Composition of the Depletion Base

The depletion base is the asset the is to be depleted. The is comprised of the adhering to four species of costs:

Acquisition costs. The price to either buy or lease property.

Development costs. The cost to prepare the residential or commercial property for legacy extraction, which consists of the price of together items together tunnels and wells.

Restoration costs. The price to restore residential or commercial property to that is original condition after depletion tasks have to be concluded.

How to calculate the Depletion Rate

To compute a unit depletion rate, subtract the salvage value of the asset from the depletion base and divide that by the total number of measurement devices that you suppose to recover. The formula because that the unit depletion price is:

(Depletion basic - rescue value)÷Total systems to be recovered

The depletion fee is climate created based on actual devices of usage. Thus, if you extract 500 barrels the oil and the unit depletion rate is $5.00 every barrel, then you fee $2,500 to depletion expense.

The approximated amount of a natural source that deserve to be recovered will change constantly together assets are slowly extracted from a property. As you revise your estimates of the continuing to be amount that extractable herbal resource, incorporate these estimates into the unit depletion rate for the remaining amount to be extracted. This is not a retreat calculation.

Example of the Depletion Method

Pensive Corporation’s subsidiary Pensive Oil drills a well with the on purpose of extract oil native a recognized reservoir. It incurs the following costs related come the acquisition of building and development of the site:


In addition, Pensive Oil approximates that it will certainly incur a site restoration expense of $57,000 as soon as extraction is complete, for this reason the full depletion basic of the residential property is $600,000.

Pensive’s geologists calculation that the proven oil reserves that space accessed by the well are 400,000 barrels, for this reason the unit depletion charge will be $1.50 per barrel that oil extract ($600,000 depletion basic / 400,000 barrels).

In the an initial year, Pensive Oil extracts 100,000 barrels that oil from the well, which outcomes in a depletion charge of $150,000 (100,000 barrels x $1.50 unit depletion charge).

At the start of the second year the operations, Pensive’s geologists worry a revised estimate of the remaining amount of proven reserves, through the new estimate that 280,000 barrels being 20,000 barrels reduced than the original estimate (less extractions currently completed). This means that the unit depletion charge will increase to $1.61 ($450,000 continuing to be depletion basic / 280,000 barrels).

During the 2nd year, Pensive Oil extracts 80,000 barrels of oil indigenous the well, which outcomes in a depletion charge of $128,800 (80,000 barrels x $1.61 unit depletion charge). In ~ the end of the 2nd year, over there is still a depletion base of $321,200 that must be fee to price in proportion to the quantity of any remaining extractions.
