Future value is the value of an investment at a specific date in the future, taking into account the interest or return it will earn over time. Present value, on the other hand, is the current value of a future sum of money, taking into account the time value of money and discounting it back to its current value. Net present value is the difference between the present value of cash inflows and the present value of cash outflows over a specific time period, used to determine the profitability of an investment or project. In summary, future value looks at the value of an investment in the future, present value looks at the current value of future cash flows, and net present value compares the present value of cash inflows and outflows to determine the profitability of an investment. **
