The general method of determination of time series averages and approximate formulas of its calculation are described. Calculation of averages for time series both: moment series and interval series is considered. On the assumption of the approach, based on the premise that economic indicators are the continuous functions of time, the exact formulas of average calculation are given. The formulas applied in practice for moment series are the result of numeral (approximate) integration by the method of trapezoids. More exact formula for average moment series got on the basis of numeral integration by the method of parabolas is adduced.
