# Equivalent Annual Cost Calculator

Introduction

Managing finances often involves comparing costs and investments over time. One crucial metric for this purpose is the Equivalent Annual Cost (EAC). The EAC helps you evaluate the true cost of an investment or expense on an annual basis, making it easier to assess and compare different financial options. In this article, we’ll introduce you to the concept of Equivalent Annual Cost and provide a user-friendly calculator to compute it.

Formula

The Equivalent Annual Cost (EAC) formula is a straightforward way to calculate the annual cost of an investment or expense over a specified number of years. It is calculated using the following formula:

EAC = (Initial Cost + Annual Cost * Number of Years) / Number of Years

How to Use

To calculate the Equivalent Annual Cost using our calculator:

1. Enter the initial cost of the investment or expense in the “Initial Cost” field.
2. Input the annual cost associated with the investment or expense in the “Annual Cost” field.
3. Specify the number of years over which you want to calculate the EAC in the “Number of Years” field.
4. Click the “Calculate” button, and the EAC will be displayed in the “Equivalent Annual Cost” field.

Example

Let’s say you are considering purchasing a piece of equipment for your business. The equipment costs \$5,000 initially, with an annual maintenance cost of \$800. You plan to use it for five years. Using the Equivalent Annual Cost formula:

EAC = (\$5,000 + \$800 * 5) / 5 EAC = (\$5,000 + \$4,000) / 5 EAC = \$9,000 / 5 EAC = \$1,800

So, the Equivalent Annual Cost of the equipment is \$1,800 per year.
