The Formula Explained
Simple Interest Formula: Interest = Principal × Rate × Time
Glossary of Terms
- Principal Amount: The initial sum of money invested or borrowed.
- Annual Interest Rate (%): The yearly interest percentage applied to the principal.
- Time Period (Years): The duration for which the money is invested or borrowed.
- Total Interest: The total interest earned or owed over the period.
- Total Amount: The sum of the principal and the total interest.
Practical Example
How It Works: A Step-by-Step Example
Let's say you invest $1,000 at an annual interest rate of 5% for 2 years. The simple interest earned would be calculated as follows:
Interest = 1000 × 0.05 × 2 = $100
Thus, the total amount would be $1,000 + $100 = $1,100.
