How should inflation be treated in a total cost of ownership (TCO) calculation?

In a total cost of ownership (TCO) calculation, inflation should be managed carefully within the financial analysis to ensure an accurate understanding of long-term costs associated with an asset. Treating inflation by exempting it from TCO but compensating in the discount rate reflects a common approach in financial modeling.

This method is valid because when calculating TCO, direct operational costs, initial purchase price, and maintenance costs are considered. However, these costs can be significantly influenced by inflation over time. Instead of adding inflation directly to the TCO, it is common to adjust the discount rate used in net present value (NPV) calculations to reflect expected inflation. This approach allows for a more precise estimation of the asset's value adjusted for the time value of money without overcomplicating the initial TCO figure with inflationary increases directly.

By incorporating inflation into the discount rate, the overall impact of inflation is acknowledged, which helps in making better financial decisions regarding asset investments. It effectively preserves the integrity of the TCO analysis while still ensuring future cost expectations align with inflation projections. This method reflects current best practices in financial assessments, particularly when evaluating long-term assets in fluctuating economic conditions.
