The calculator uses the simple interest formula:

Where:

• \( Principal \) — Initial investment amount in USD
• \( Rate \) — Annual interest rate as a decimal
• \( Time \) — Investment period in years

Explanation: This formula calculates simple interest earnings without compounding. For compound interest, additional calculations would be required.
