Effective Annual Rate

Definition

The effective annual rate (EAR) is the interest rate on an investment or loan that is compounded annually, reflecting the total cost of borrowing or the total return on an investment over a year. This rate is important in capital budgeting because it allows for a more accurate comparison of different investment opportunities that may have varying compounding periods, such as monthly or quarterly compounding. Understanding EAR helps decision-makers evaluate the true profitability of projects and align their financial strategies accordingly.

5 Must Know Facts For Your Next Test

1. The effective annual rate accounts for compounding, providing a more accurate measure of financial performance than simple interest calculations.
2. EAR can be calculated using the formula: $$ EAR = (1 + \frac{r}{n})^n - 1 $$, where 'r' is the nominal rate and 'n' is the number of compounding periods per year.
3. When comparing investments with different compounding frequencies, using the effective annual rate standardizes the comparison and highlights which investment yields better returns.
4. A higher effective annual rate indicates a higher total return or cost, making it crucial for evaluating the feasibility of capital projects.
5. Understanding effective annual rates helps organizations make informed decisions about financing options and investment strategies.
