Post Office RD vs Post Office FD: Fixed deposits (FDs) and recurring deposits (FDs) are popular choices for conservative investors. Traditionally, they are favoured for two main reasons: both offer guaranteed returns and come with lower risk compared to stocks and other equity-related investments. Now, India Post - which also provides a host of banking and financial services in addition to postal services in the country - offers four maturity options in its fixed deposit scheme (known as the National Savings Time Deposit Account) and a single maturity of five years in its recurring deposit scheme (known as the National Savings Recurring Deposit Account).

Power of Compounding: Why patience matters

Compounding is the process where the value of an investment grows because the earnings on an investment, both capital gains and interest, earn interest as time passes. Simply put, it’s 'interest on interest', meaning that the amount initially earned as interest stays back in the instrument to earn more interest in the remaining investment period.

Both in RD and FD, the longer a depositor's money is invested, the larger is the benefit from compounding, leading to significantly greater returns. 

All in all, the power of compounding only multiplies over time.
