Interest Rate

Default or Penal Interest is an extra rate of interest charged by banks or lenders when a borrower fails to pay installments or dues on time.
When borrowers delay payments, banks impose a penalty to discourage defaults and compensate for the risk and inconvenience.
This penal interest increases the effective cost of borrowing for the defaulter.
In the larger market, high levels of default risk push banks to keep market interest rates higher to cover possible losses.
Therefore, the risk of default and the resulting penal interest directly influence the market rate of interest.

This is a compound interest problem where interest is added to the principal annually.
Given:
Principal (P) = ₹ 30,000
Rate of interest (R) = 10% p.a.
Time (n) = 3 years
Compound Interest Formula:

Substituting the values:




Total Amount = ₹ 39,930
Interest Received = Amount - Principal
Interest = ₹ 39,930 ₹ 30,000
Interest = ₹ 9,930
Therefore, Vishal will receive ₹ 9,930 as interest and the total amount after 3 years will be ₹ 39,930.

Banks primarily earn income by lending money to borrowers and charging them interest on loans and advances.
This interest income forms the largest portion of a bank’s total income and is the biggest entry on the income side of its Profit and Loss Account.
Other sources like service charges, commission, and investment income do contribute, but they are usually much smaller than the interest earned.
Banks lend to individuals, businesses, and governments and collect interest payments over time, which is a stable and significant source of revenue.
That’s why monitoring the quality of loans is so important — NPAs affect this core income directly.
Therefore, the correct answer is ‘Interest earned on advances and loans’.

In banking and finance, interest refers to the cost of borrowing money or the return earned on deposits or investments.
It is always stated in terms of a rate — that is, a percentage of the principal amount.
The standard practice is to express this rate annually, which is why we often see terms like ‘annual interest rate’ or ‘per annum’.
For example, if you deposit money in a savings account with an annual interest rate of 5%, it means you earn 5% of the principal every year.
Similarly, when taking a loan, the borrower pays interest annually at the specified rate.
Stating the interest rate per annum makes it easy to compare different financial products and understand the cost or return over a full year.
Therefore, the correct answer is: interest is expressed in terms of Rate of Interest per annum.

A fixed rate of interest and a floating rate of interest are two common types used in loans and investments.
1) Rate Stability:
In a fixed rate, the interest remains the same throughout the loan period, giving certainty to borrowers about repayment amounts.
In a floating rate, the interest rate changes according to market conditions or benchmark rates like MCLR or Repo Rate.
2) Risk and Flexibility:
Fixed rate loans protect borrowers from market fluctuations but may be higher than current floating rates.
Floating rate loans can benefit borrowers when market rates fall but can increase payments when rates rise.
This difference helps customers choose based on risk preference and market trends.
