A Fixed Deposit (FD)—also known as a Term Deposit—is a low-risk financial instrument offered by commercial banks and financial institutions.
The fundamental mathematical formulas executed by this tool include:
\(\text{Compound Maturity Value } (A) = P \times \left(1 + \frac{r}{c \times 100}\right)^{c \times t}\)
\(\text{Simple Interest Maturity } (A) = P \times \left(1 + \frac{r \times t}{100}\right)\)
Where \(P\) is principal deposit, \(r\) is annual interest rate %, \(c\) is compounding frequency (12 monthly, 4 quarterly, 2 half-yearly, 1 yearly), and \(t\) is tenure in years.
\(\text{Total Net Interest Yield} = A - P\)
Most financial institutions calculate compound interest on a Quarterly Basis. Compounding generates higher effective returns than simple interest over longer tenures.
