Equivalent Periodic Nominal Rate: -

Calculation Details:

Explanation: The equivalent periodic nominal rate is calculated using the formula:

Equivalent Rate (r') = (1 + R/m)^(m/q) - 1 * q

Where:

• R: Interest Rate
• m: Compounding Frequency
• q: New Compounding Frequency
• r': Equivalent Periodic Nominal Rate

What is Equivalent Interest Rate?

The Equivalent Interest Rate, also known as the Effective Interest Rate or Annual Equivalent Rate (AER), is a financial concept used to express the annualized interest rate that takes into account compounding of interest over time. It is a standardized way to represent the true cost or return on financial products, such as loans, investments, and savings accounts.

The Equivalent Interest Rate is particularly important when comparing and evaluating different financial products because it considers both the nominal interest rate and the frequency of compounding. It allows individuals to make more accurate comparisons between financial options.

All Formulae Related to Equivalent Interest Rate

Here are the formulae related to Equivalent Interest Rate (Annual Equivalent Rate or AER) in non-LaTeX format:

1. Equivalent Interest Rate Formula:
• AER = [(1 + (r / n))^n] – 1

Where:

• AER is the Annual Equivalent Rate (Equivalent Interest Rate).
• r is the nominal interest rate (stated rate) as a decimal.
• n is the number of times that interest is compounded per year.

This formula is used to calculate the Equivalent Interest Rate, which reflects the actual annual return or cost of a financial product, accounting for compounding.

1. Nominal Interest Rate Conversion:
• r = (AER + 1)^(1/n) – 1

Where:

• r is the nominal interest rate (stated rate) as a decimal.
• AER is the Annual Equivalent Rate (Equivalent Interest Rate).
• n is the number of times that interest is compounded per year.

This formula allows you to convert the AER back into the nominal interest rate when needed for financial calculations.
