Grow Your Savings with a Recurring Deposit
A Recurring Deposit (RD) allows you to save a fixed amount every month while earning interest similar to a Fixed Deposit. It is an excellent tool for disciplined savings and meeting short-term financial goals.
Our RD calculator uses the standard formula adopted by most banks, which typically involves quarterly compounding of interest. This means your monthly savings grow faster than simple interest savings.
