1. What Is Annual Equivalent Cost?

Annual Equivalent Cost (AEC) is a financial metric used to convert a present worth amount into an equivalent uniform annual cost over a specified period, considering the time value of money through an interest rate.

2. How Does The Calculator Work?

The calculator uses the AEC formula:

Where:

• \( AEC \) — Annual Equivalent Cost (dollars/year)
• \( PW \) — Present Worth (dollars)
• \( i \) — Interest Rate (decimal)
• \( n \) — Number of Years
• \( (A/P, i, n) \) — Capital Recovery Factor

Explanation: The (A/P, i, n) factor converts a present amount into an equivalent uniform annual series over n years at interest rate i.

3. Importance Of AEC Calculation

Details: AEC is crucial for comparing investment alternatives with different lifetimes and cost patterns, helping decision-makers evaluate the true annual cost of capital investments and long-term projects.

4. Using The Calculator

Tips: Enter present worth in dollars, interest rate as a percentage (e.g., 5 for 5%), and number of years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What Is The Capital Recovery Factor?
A: The (A/P, i, n) factor calculates the uniform annual payment required to recover a present investment over n years at interest rate i.

Q2: When Should I Use AEC Analysis?
A: Use AEC when comparing projects with different lifetimes, evaluating equipment replacement decisions, or analyzing long-term capital investments.

Q3: How Does Interest Rate Affect AEC?
A: Higher interest rates increase the AEC because the time value of money requires larger annual payments to recover the initial investment.

Q4: Can AEC Be Used For Revenue Projects?
A: Yes, the same principle applies to Annual Equivalent Worth (AEW) for revenue-generating projects, where positive values indicate economic attractiveness.

Q5: What Are The Limitations Of AEC?
A: AEC assumes constant interest rates, may not account for inflation, and requires accurate estimates of project lifespan and discount rates.
