Compound interest refers to the interest calculated not only on the principal amount but also on the accumulated interest itself. This means that the interest earned in each period is added to the principal amount and then earns interest itself, leading to a greater total return over time.
Yearly Basis:
Each year, the interest is calculated and added to the principal.
This allows for a consistent and predictable calculation of the interest earned.
It is commonly used for comparing investments with a fixed interest rate.
Half-Yearly Basis:
Interest is calculated and added to the principal only once every half-year.
This provides an adjusted interest rate due to the compounding effect over multiple periods.
It is advantageous when dealing with seasonal changes or situations where the interest rate fluctuates significantly.
Examples:
Scenario 1: Annual Interest:
Principal = $100
Interest rate = 5% per year
Time period = 1 year
Calculation:
Interest = Principal * Interest rate = 5
Total amount = Principal + Interest = 5 = $105
Scenario 2: Half-Yearly Interest:
Principal = $100
Interest rate = 5% per year
Time period = 6 months
Calculation:
Interest = Principal * Interest rate = 5
Interest earned in 6 months = Interest in the first half-year + Interest in the second half-year = (5) = $10
Total amount = Principal + Interest = 10 = $110
Key Differences:
The presence of compounding in the yearly basis leads to a higher potential return compared to the half-yearly basis.
The half-yearly basis offers more accurate returns when the interest rate fluctuates.
Both methods provide a way to compare and make informed financial decisions based on the specific circumstances
