A Fixed Deposit (FD) is a financial instrument provided by banks or NBFCs which offers investors a higher rate of interest compared to a regular savings account, until the given maturity date. It may or may not require the creation of a separate account. They are considered to be very safe investments. FD returns can be calculated using an FD calculator which makes the calculation process easy and accurate.

Understanding Fixed Deposits

Fixed Deposit (FD) is a type of term investment offered by several banks and NBFCs. The deposit is made for a fixed period of time, which can range from 7 days to 10 years. The interest rate on FDs is fixed and is generally higher than the interest rate on savings accounts. The interest earned on FDs is either paid at regular intervals or is reinvested, depending on the investor’s choice.

M = P + (P x r x t/100), where 


  • A is the maturity amount
  • P is the principal amount
  • R is the rate of interest
  • T is the time in years
