Find The Amount On 1600 For 9 Month At A Rate 5% Per Annum At Simple Interest
Understanding Simple Interest
Simple interest is a type of interest calculated on the initial principal amount, without taking into account the interest that has accrued on the principal. It is a straightforward and easy-to-understand concept, making it a popular choice for many financial calculations.
The Formula for Simple Interest
The formula for simple interest is:
I = PRT
Where:
- I is the interest earned
- P is the principal amount (initial amount borrowed or invested)
- R is the rate of interest per annum (as a decimal)
- T is the time period (in years)
Calculating Simple Interest for 9 Months
In this example, we want to calculate the simple interest on a principal amount of $1600 for a period of 9 months at a rate of 5% per annum.
First, we need to convert the time period from months to years. Since there are 12 months in a year, we can calculate the time period as follows:
T = 9 months / 12 months/year = 0.75 years
Now, we can plug in the values into the simple interest formula:
I = PRT I = $1600 x 0.05 x 0.75 I = $120
So, the simple interest earned on a principal amount of $1600 for a period of 9 months at a rate of 5% per annum is $120.
Calculating the Total Amount
To find the total amount, we need to add the principal amount and the interest earned:
Total Amount = Principal Amount + Interest Earned Total Amount = $1600 + $120 Total Amount = $1720
Therefore, the total amount after 9 months at a rate of 5% per annum is $1720.
Real-World Applications of Simple Interest
Simple interest has numerous real-world applications, including:
- Banking and Finance: Simple interest is used to calculate interest on loans, credit cards, and savings accounts.
- Investments: Simple interest is used to calculate returns on investments, such as bonds and certificates of deposit (CDs).
- Personal Finance: Simple interest is used to calculate interest on personal loans, credit cards, and savings accounts.
Conclusion
In conclusion, simple interest is a straightforward and easy-to-understand concept that is widely used in finance and personal finance. By using the simple interest formula, we can calculate the interest earned on a principal amount for a given time period and rate of interest. In this example, we calculated the simple interest on a principal amount of $1600 for a period of 9 months at a rate of 5% per annum and found the total amount to be $1720.
