Calculation Details
The calculator computes the final amount and total interest accrued using the compound interest formula:
A = P (1 + r/n)nt
Where:
- A is the final amount.
- P is the principal amount.
- r is the annual interest rate (decimal).
- n is the number of compounding periods per year.
- t is the time the money is invested for in years.
Limitations of the Calculator:
- It does not account for additional contributions or withdrawals made during the investment period.
- It assumes that the interest rate remains constant over the entire period.
- Dates are validated but may not handle all edge cases gracefully.
