Formula Explained
The formula for calculating fixed account interest is:
Simple Interest Formula
Interest = Principal × Rate × Time
Final Amount = Principal + Interest
Where:
- Principal is the initial amount of money
- Rate is the annual interest rate (in decimal form)
- Time is the number of years the money is invested
For example, if you deposit $1,000 at an annual interest rate of 5% for 3 years, the interest earned would be $150, and the final amount would be $1,150.
Worked Examples
Here are some examples of how to calculate fixed account interest:
Example 1: Basic Calculation
Principal: $5,000
Interest Rate: 4%
Time: 2 years
Interest = $5,000 × 0.04 × 2 = $400
Final Amount = $5,000 + $400 = $5,400
Example 2: Higher Interest Rate
Principal: $10,000
Interest Rate: 6%
Time: 5 years
Interest = $10,000 × 0.06 × 5 = $3,000
Final Amount = $10,000 + $3,000 = $13,000
| Principal | Rate (%) | Time (years) | Interest | Final Amount |
|---|---|---|---|---|
| $2,000 | 3 | 1 | $60 | $2,060 |
| $10,000 | 5 | 3 | $1,500 | $11,500 |
