# Fixed deposit calculators: What are FD calculators and how do they work?

[ecis2016.org] A fixed deposit calculator assists an investor in estimating the FD’s maturity amount for a specific term.

A fixed deposit (FD) is a financial product that is widely available from banks and non-banking financial companies (NBFCs). Fixed deposits are available in varying tenures and a predetermined rate of interest for each tenure, which is constant regardless of market volatility. You can invest for a period of seven days to 10 years. The higher the interest rate and interest collected owing to the power of compounding, the greater will be the returns on the deposit amount over a longer period.
