Calculating the future value of $6 over the next 78 years allows you to see how much your principal will grow based on the compounding interest.

So if you want to save $6 for 78 years, you would want to know approximately how much that investment would be worth at the end of the period.

To do this, we can use the future value formula below:

$$FV = PV \times (1 + r)^{n}$$

We already have two of the three required variables to calculate this:

- Present Value (FV): This is the original $6 to be invested
- n: This is the number of periods, which is 78 years

In the table below, we have calculated the future value (FV) of $6 over 78 years for expected rates of return from 2% to 30%.

The table below shows the present value (PV) of $6 in 78 years for interest rates from 2% to 30%.

**As you will see, the future value of $6 over 78 years can range from $28.12 to $4,631,617,970.60.**
