  2. Time value of money - Wikipedia

    en.wikipedia.org/wiki/Time_value_of_money

    The present value formula is the core formula for the time value of money; each of the other formulas is derived from this formula. For example, the annuity formula is the sum of a series of present value calculations. The present value (PV) formula has four variables, each of which can be solved for by numerical methods:
