Effective financial modeling requires a solid grasp of various depreciation methods to accurately forecast asset values and expenses. Mastering these methods is crucial for creating dynamic and accurate financial models that drive informed decision-making. Here are key types of depreciation calculations you should know:

1. Straight-Line

Easiest and most common, spreading the cost evenly over the asset’s useful life.

2. Declining Balance

Applies a constant rate to the declining book value, with higher expenses in the early years.

3. Double Declining Balance 

A more aggressive form of the declining balance, using double the implied straight line rate.

4. Sum of the Year's Digits

An accelerated method to calculate depreciation expense based on the asset’s expected life.

5. Units of Production

Ties depreciation to actual usage or production levels, ideal for assets with wear tied to activity.
