The video presents the exponential smoothing forecast formula as a weighted average of the current actual demand and the current forecast. The next period's forecast is calculated by multiplying the current actual demand by the smoothing constant α\alpha and adding the product of the previous forecast and the complementary weight (1−α)(1-\alpha).

Conditions: The formula is used to compute the forecast for period t+1t+1.; The same smoothing constant α\alpha is used throughout the worked example.; The initial forecast F1F_1 must be specified before recursion can begin.
