What Is a Replacement Cost?

A replacement cost is an expense a business must undertake to replace an essential asset of the company at the same or equal value. The asset to be replaced could be a building, investment securities, accounts receivable or liens. The replacement cost can change, depending on changes in the market value of the asset and any other costs required to prepare the asset for use. Accountants use depreciation to expense the cost of the asset over its useful life.

Replacing an asset can be an expensive decision, and companies analyze the net present value (NPV) of the future cash inflows and outflows to make purchasing decisions. Once an asset is purchased, the company determines a useful life for the asset and depreciates the asset's cost over the useful life.

Understanding Replacement Cost

As part of the process of determining what asset is in need of replacement and what the value of the asset is, companies use a process called net present value. To make a decision about an expensive asset purchase, companies first decide on a discount rate, which is an assumption about a minimum rate of return on any company investment. A business then considers the cash outflow for the purchase and the cash inflows generated based on the increased productivity of using a new and more productive asset. The cash inflows and outflow are adjusted to present value using the discount rate, and if the net total of all present values is a positive amount, the company makes the purchase.

[Important: The cost to replace an asset can change, depending on variations in the market value of the asset and other costs needed to get the asset ready for use].

Special Considerations

When calculating the replacement cost of an asset, a company must account for depreciation costs. A business capitalizes an asset purchase by posting the cost of a new asset to an asset account, and the asset account is depreciated over the asset’s useful life. Depreciation matches the revenue earned by using the asset with the expense of using the asset over time. The cost of the asset includes all costs to prepare the asset for use, such as insurance costs and the cost of setup.

Some assets are depreciated on a straight-line basis, meaning the cost of the asset is divided by the useful life to determine the annual depreciation amount. Other assets are depreciated on an accelerated basis so more depreciation is recognized in the early years and less in later years. The total depreciation expense recognized over the asset’s useful life is the same, regardless of which method is used.

Replacement Cost Budgeting

Given the cost of replacing expensive assets, well-managed firms create a capital expenditure budget to plan for both future asset purchases and for how the firm will generate cash inflows to pay for the new assets. Budgeting for asset purchases is critical because replacing assets is required to operate the business. A manufacturer, for example, budgets for equipment and machine replacement, and a retailer budgets to update the look of each store.

Key Takeaways

  • The replacement cost is an amount that a company pays to replace an essential asset that is priced at the same or equal value. 
  • The cost to replace the asset can change, depending on the market value of the asset and how much it costs to get the asset up and running, once purchased.
  • Companies look at the net present value and depreciation costs when deciding which assets need to be replaced and whether the cost is worth the expense.
