When companies use the cost principle, they assign values to their large assets – such as real estate or equipment – equal to what they originally paid for the asset, regardless of when they bought it. While this means that the value they place on assets is stable over time, it can also be very conservative, and sometimes inaccurate for assets purchased 10 or more years ago. There is an exception for intangible assets purchased from another business. Issues can also arise when selling an asset, since it would likely be sold at fair market value, not historical cost.

Value streams are the profit centers of a company, which is any branch or division that directly adds to its bottom-line profitability. For example, cost accountants using ABC might pass out a survey to production-line employees who will then account for the amount of time they spend on different tasks. The costs of these specific activities are only assigned to the goods or services that used the activity. This gives management a better idea of where exactly the time and money are being spent. If the variance analysis determines that actual costs are higher than expected, the variance is unfavorable.

If you wish to be compliant with GAAP, the cost principle should be used. The cost principle is not applicable to financial investments, where accountants are required to adjust the recorded amounts of these investments to their fair values at the end of each reporting period. While most small business owners will continue to use only accounting cost to determine the financial health of their business, there’s a strong case to be made for introducing economic cost into the mix.
