Calculate the interest earned or paid on a principal amount over time.
How It Works:
Calculating simple interest is as easy as 1-2-3! The formula is straightforward: Interest = (Principal × Rate × Time) / 100. Here’s what each term means:
- Principal: The initial amount of money you’re starting with.
- Rate: The annual interest rate (as a percentage).
- Time: The number of years the money is invested or borrowed for.
For example, if you invest $1,000 at a 5% annual interest rate for 3 years, the interest earned would be: (1000 × 5 × 3) / 100 = $150. Your total amount after 3 years would be $1,150.
Example Calculations:
| Principal ($) | Rate (%) | Time (Years) | Interest ($) | Total Amount ($) |
|---|---|---|---|---|
| 500 | 4 | 2 | 40 | 540 |
| 1000 | 5 | 3 | 150 | 1150 |
| 2000 | 3.5 | 5 | 350 | 2350 |
| 3000 | 6 | 10 | 1800 | 4800 |
