Key Takeaways
- Equivalent Annual Cost (EAC) is a financial metric that standardizes the total net present value of an asset's costs into an annual figure for easier project comparisons.
- EAC is calculated by dividing the NPV of all costs associated with an asset by the present value annuity factor, taking into account the asset's lifespan and discount rate.
- This metric is essential for capital budgeting decisions, especially when comparing investments with different durations or cash flow profiles.
- Selecting the option with the lowest EAC can help identify the most cost-effective investment, assuming all options carry similar risk.
What is Equivalent Annual Cost (EAC)?
Equivalent Annual Cost (EAC) is a capital budgeting metric that helps you evaluate the annual cost of owning, operating, and maintaining an asset throughout its lifespan. It converts the total net present value (NPV) of all costs associated with an asset into an equivalent annual amount, making it easier to compare projects or assets with different lifespans. For instance, when deciding between two machines with varying operational durations, EAC allows for a straightforward comparison.
The EAC is calculated by dividing the NPV of all relevant costs, which may include the initial purchase price, maintenance, and operational expenses, by the present value annuity factor for the asset’s lifespan at a specified discount rate. This metric is especially useful in capital budgeting, allowing for informed decisions between options such as leasing versus buying assets or evaluating the impact of maintenance on asset life.
- Facilitates comparisons of investments with unequal lifespans
- Assists in determining optimal replacement cycles
- Helps assess the overall economics of an asset
Key Characteristics of EAC
EAC has several defining characteristics that make it a valuable tool in financial decision-making. Understanding these traits can help you apply EAC effectively in your assessments. Here are some key characteristics:
- Annualized Cost: EAC provides a yearly cost estimate, allowing for easier comparisons across different assets.
- Time Value of Money: It incorporates the time value of money by discounting future costs, ensuring that you consider the financial impact over time.
- Flexibility: EAC can be adjusted for various factors, such as changes in maintenance costs or different discount rates, making it adaptable to various scenarios.
How EAC Works
The calculation of EAC involves a few straightforward steps. First, you need to determine the NPV of all costs associated with the asset. This includes the initial purchase price, operating, and maintenance costs, minus any salvage value if applicable. Once you have this figure, you divide it by the annuity factor, which accounts for the discount rate and the asset's lifespan.
The standard formula for calculating EAC is as follows:
EAC = NPV of costs / Annuity factor
Where the annuity factor is calculated using the formula:
Annuity factor = (1 - (1 + r)-n) / r
In this formula, r represents the discount rate and n is the asset's lifespan in years. Using this method allows you to compare different investment options effectively.
Examples and Use Cases
Consider a scenario where you are evaluating two machines for your business. Machine A costs $130,000 and has a lifespan of 5 years, while Machine B costs $150,000 and lasts for 4 years. Both machines have an annual maintenance cost of $5,000 and a discount rate of 10%.
For Machine A, the annuity factor can be calculated, leading to an EAC of approximately $39,210.52. On the other hand, you would perform a similar calculation for Machine B to determine its EAC. This comparison will guide you in selecting the machine that provides the best financial value for your operations.
- Example 1: Comparing machines with different lifespans
- Example 2: Evaluating lease versus buy scenarios
Important Considerations
While EAC is a powerful tool, there are some important considerations to keep in mind. For instance, EAC assumes that costs remain constant annually, which may not reflect real-world variability. Additionally, it requires that the projects being compared have equal risk profiles; otherwise, the comparisons may yield misleading results.
Moreover, EAC does not account for potential revenue generation from the asset, focusing solely on costs. Therefore, it should be used in conjunction with other financial metrics, such as NPV or internal rate of return (IRR), to provide a comprehensive view of investment options.

Frequently Asked Questions
Equivalent Annual Cost (EAC) is a capital budgeting metric that converts the total net present value (NPV) of costs related to owning, operating, and maintaining an asset into an annual cost. This allows for fair comparisons between projects or assets with different lifespans.
EAC is calculated by dividing the NPV of all costs by the present value annuity factor, which depends on the discount rate and the asset's lifespan. The formula is EAC = NPV of costs / Annuity factor, where the annuity factor accounts for the time value of money.
EAC is important because it enables investors to compare investments with different durations and cash flow patterns, such as lease versus buy decisions. By converting costs into an annual format, it simplifies the evaluation of long-term financial commitments.
Yes, EAC is specifically designed for comparing assets with unequal lifespans. It provides a standardized way to assess the annual cost of ownership, making it easier to identify the most cost-effective option among different assets.
EAC calculations typically include the initial purchase price, annual maintenance costs, and any operational expenses, discounted to present value. Additionally, factors like the discount rate and asset lifespan are crucial in determining the annuity factor used in the calculation.
EAC assists in identifying the best time to replace an asset by comparing the annual costs associated with keeping an existing asset versus acquiring a new one. This helps businesses optimize their capital expenditures and minimize long-term costs.
The primary advantage of EAC is that it simplifies the comparison process for assets with different lifetimes by presenting costs on an annual basis. This approach also accounts for the time value of money, making it a more accurate tool for financial decision-making.
