What Is This Tool?
This calculator helps you estimate the total value of an investment that grows using simple interest. It applies a straightforward formula to calculate interest earned and the final balance without compounding effects.
How to Use This Tool?
- Enter the initial investment amount (principal).
- Input the annual interest rate as a decimal (e.g., 0.06 for 6%).
- Specify the duration of the investment in years.
- Click the calculate button to view interest earned and total investment value.
- Review the output to understand your simple interest growth.
Key Features
- Calculates investment growth based on simple (non-compounding) interest.
- Uses the formula A = P + (P × r × t) to determine total value.
- Displays interest earned and final investment amount.
- Accepts inputs for principal amount, annual interest rate, and time period in years.
- Provides quick, precise results suitable for financial planning and education.
Examples
- For an initial investment of $4,000 at an annual interest rate of 6% over 5 years, interest earned is calculated as I = 4000 × 0.06 × 5 = 1,200, resulting in a total value of A = 4000 + 1200 = 5,200.
