Jm
O One that compounds terest daily.
The Correct Answer and Explanation is :
The savings account that will earn you the least money is the one that earns simple interest monthly.
Explanation
To understand why a monthly simple interest account earns the least, we first need to define the types of interest:
- Simple Interest: This is calculated only on the principal amount, or the initial deposit, throughout the entire term of the investment. The formula for calculating simple interest is:
[
\text{Interest} = P \times r \times t
]
where (P) is the principal, (r) is the annual interest rate, and (t) is the time in years.
- For a monthly simple interest account, interest is credited once a month, but it does not accrue on previously earned interest. As a result, you only earn interest on your principal, leading to lower overall earnings compared to accounts that compound interest.
- Compounding Interest: This type of interest is calculated on the principal and also on the accumulated interest from previous periods. This means your interest earns interest, leading to higher overall returns.
- Daily Compounding: Interest is calculated and added to the principal daily, leading to more frequent compounding and higher returns.
- Monthly Compounding: Interest is added to the principal once a month, which is better than simple interest because you earn interest on the accumulated interest.
In comparing the options:
- Simple Interest Monthly: You earn interest only on your initial deposit.
- Simple Interest Daily: Similar to monthly but slightly better due to daily calculations, though it still lacks compounding.
- Compounding Monthly: Interest is calculated more frequently, leading to better returns than simple interest.
- Compounding Daily: This method yields the highest returns since interest is calculated and added every day, maximizing the benefits of compounding.
In conclusion, while simple interest accounts have their advantages, the monthly simple interest account yields the least compared to any compounding options, which benefit significantly from the effects of compounding.
