Understanding Simple Interest
Simple interest is a quick and easy method of calculating the interest charge on a loan or investment. It is determined by multiplying the principal amount by the interest rate and the time period.
Formula
I = P × R × T
Where:
• I = Simple Interest
• P = Principal amount (the original amount of money borrowed or invested)
• R = Annual interest rate (as a decimal)
• T = Time (in years)
Where:
• I = Simple Interest
• P = Principal amount (the original amount of money borrowed or invested)
• R = Annual interest rate (as a decimal)
• T = Time (in years)
Key Concepts
- Principal (P): The initial amount of money invested or borrowed.
- Interest Rate (R): The percentage rate at which interest is charged or earned per year.
- Time (T): The duration for which the money is borrowed or invested.
