## Average Cost Basis

Average cost basis is a method of calculating the cost of an asset by taking the total cost of all units purchased and dividing it by the total number of units held. This method smooths out the impact of price fluctuations over time, providing a single average price per unit.

It is often considered a simpler and more intuitive way to manage tax reporting, especially for assets purchased in many small, recurring transactions. However, not all jurisdictions allow the use of average cost basis for digital assets.

If permitted, it can reduce the administrative burden of tracking individual purchase lots. When an asset is sold, the gain or loss is calculated using this average price.

It is particularly popular among retail investors who engage in dollar-cost averaging. While it simplifies reporting, it may not offer the same tax optimization potential as specific identification methods.
