What are nominal interest rates, and how are they calculated?
Nominal interest rates, often referred to as the 'stated' or 'quoted' rate, represent the simple interest paid on a deposit generally over a period of a year. In the context of savings accounts in India, the formula to calculate nominal interest rates is:
Nominal Interest Rate = (Annual interest earned / Principal Amount) x 100
Where,
Annual interest earned is the amount of interest earned each year
Principal amount is the initial amount of money you have in your savings account

Understanding effective interest rates
The effective interest rate, on the other hand, considers the compound interest that accrues on both the initial principal and the accumulated interest from previous periods on a deposit or loan. It is a more accurate measure of the total cost (on a loan) or return on investment (on deposits) over a period. The effective interest rate formula in the context of compounding more frequently than annually is:
Effective Interest Rate = [1 + (Nominal Rate/n)]^n – 1
Differences between nominal and effective interest rates
1. Basis of calculation:
Nominal interest is calculated on the principal amount, whereas the effective interest rate considers compound interest on the principal and accumulated interest.
2. Real return:
The effective rate provides a more accurate picture of the real return or cost because it accounts for the compounding effect.
3. Compounding frequency:
Nominal rate remains constant regardless of the frequency of compounding, but the effective rate varies based on how often interest is compounded (monthly, quarterly, etc.).
4. Usage:
Nominal rates are often used in advertising because they appear lower and more attractive, while effective rates reflect the true cost or return.
5. Relevance for decision making:
For those who want a clearer understanding of their returns or costs, the effective rate is more relevant as it provides a complete picture.
6. Impact on savings:
Over longer periods, especially with higher nominal rates and more frequent compounding, the disparity between nominal and effective rates becomes more pronounced, impacting the growth of savings.
7. Regulatory perspective:
Some regulators require financial institutions to disclose both rates to ensure transparency and enable informed decision-making by consumers.
When evaluating the potential growth of savings in a bank account, it's essential to understand the difference between nominal and effective interest rates. While the nominal rate provides a basic overview, the effective rate captures the true earning potential, factoring in the power of compounding. In the context of savings accounts in India, as with many other financial instruments worldwide, a discerning saver would do well to consider both rates, understand their implications, and make informed decisions accordingly.
