Straight Line Depreciation Tables

Straight Line Depreciation Calculator Tables

The straight line depreciation tables below act as a quick reference to help you calculate straight line depreciation for a month. The tables are based on the formula for straight line depreciation as follows:

Straight Line Depreciation = Cost / Useful Life

This formula assumes that the salvage value of the asset is zero at the end of its useful life.

How to Calculate monthly straight line depreciation

As an example of calculating straight line depreciation using the tables, suppose a business purchased at asset for 25,000 with an estimated useful life of 5 years.

Using the formula shown above, we could calculate the depreciation as follows:

Cost = 25,000
Useful life = 5 years
Straight line depreciation = Cost / Useful Life
Straight line depreciation = 25,000 / 5 = 5,000 each year
Monthly depreciation = 5,000 / 12 = 417 per month

However, to avoid having to carry out this calculation, the straight line depreciation calculator table below can be used.

If we look at the straight line depreciation tables row for the amount 25,000 and the column for years 5, then the value given by the table is 417, which is the same as in the calculation above.

Amounts can be combined to give the total amount of depreciation, for example if an asset costs 16,000 with a useful life of 4 years, the depreciation is calculated by taking the amount for 15,000 and the amount for 1,000 from the 4 years column, which is 313 + 21 = 334 per month.
