Future Value, Single Amount

Since the number of periods (n or t) is one, FV=PV(1+i), where i is the interest rate.

Multi-period investments take place over more than one period (usually multiple years). They can either accrue simple or compound interest.

The Future Value can be calculated by knowing the present value, interest rate, and number of periods, and plugging them into an equation.

Calculating FV is a matter of identifying PV, i (or r), and t (or n), and then plugging them into the compound or simple interest formula.
