Your amount can be doubled through Fixed Deposits, Recurring Deposits and Post Office Schemes if you keep the money invested for a long term. To find out how long this will take, you can use the Rule of 72. Let's understand how to use it:

How to Use the Rule of 72
First, you need to determine the rate of return on the platform where you have invested. Based on this return, you can estimate how long it will take for your money to double.

Let's understand with examples:

PPF (Public Provident Fund) - 7.1% interest rate
72 / 7.1 = 10.14 years

RD (Recurring Deposit Scheme) - 6.7% (Post Office)
72 / 6.7 = 10.75 years

FD (Fixed Deposit) - 7.5% interest rate
72 / 7.5 = 9.6 years

If the interest rate on an FD is 8%:
72 / 8 = 9 years
