Equivalent Periodic Nominal Rate: -
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:
- 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.
- 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.

The post is good and informs me about the basic concept of Equivalent Interest Rate and its applications.
I struggle to see the practical applications mentioned here playing out in reality. It seems a bit far-fetched.
Though it provides basic information, I feel the post lacks depth and might leave questions unanswered for some readers.
The Equivalent Interest Rate has always been a bit confusing but your post has helped a great deal in understanding it. I appreciate your approach.
Very informative and useful post! This has been explained very nicely and would be beneficial for everyone.
The author has done a great job of simplifying such a complex financial concept. I would definitely recommend this to others.
This opens up a whole new world of finance to me. I can’t thank you enough for this comprehensible explanation.
This is a must-read for anyone who wants to understand the nitty-gritty of financial products and make informed decisions.
I’m not sure if the benefits are as significant as they are claimed here. The post seems to exaggerate the impact.
This is a good start for individuals new to finance, but it may not be as impactful for experienced professionals.
