Where:
- FV: Future Value of the investment/loan.
- P: Principal amount (initial investment/loan).
- r: Annual nominal interest rate (as a decimal).
- n: Number of times the interest is compounded per year.
- t: Time the money is invested/borrowed for, in years.
Limitations
While this calculator provides a detailed computation of the interest, it assumes static interest rates and does not account for changes in rates or additional contributions or withdrawals over the term of the investment/loan.
