This tool helps you calculate the future value of your investments with compound interest.
How It Works
The compound interest calculator allows you to determine the total amount that will accumulate over time based on the initial principal amount, annual interest rate, the number of times interest is compounded per year, and the total number of years the investment is held.
Instructions
- Enter the initial principal amount (P) in the first input field.
- Input the annual interest rate (r) as a percentage in the second input field.
- Specify the number of times the interest is compounded per year (n) in the third input field.
- Provide the total number of years (t) for the investment in the fourth input field.
- Click the “Calculate” button to see the results.
Explanation
The calculator uses the compound interest formula: A = P (1 + r/n)^(nt), where:
- P = Principal amount
- r = Annual interest rate (in decimal)
- n = Number of times the interest is compounded per year
- t = Number of years the money is invested
- A = Total amount after t years including interest
The result table shows the entered principal amount, annual interest rate, times compounded per year, total invested time, and the calculated total amount after the specified time period.
Limitations
This calculator assumes that the interest rate remains constant throughout the investment period and that interest is compounded at regular intervals as specified. Any changes in interest rate or compound frequency are not accounted for in this calculation.
