Exponential Smoothing Forecast Calculator
Calculate demand forecasts using simple exponential smoothing. Apply a smoothing constant (alpha) to weight recent demand more heavily.

Calculate demand forecasts using simple exponential smoothing. Apply a smoothing constant (alpha) to weight recent demand more heavily.
Calculate forecast bias and tracking signal to detect systematic over- or under-forecasting. Identify directional errors in your demand forecast.
Calculate Mean Absolute Deviation to measure forecast accuracy in units. Determine the average absolute difference between actual and forecast demand.
Calculate Mean Absolute Percentage Error to measure forecast accuracy. Express average deviation between actual and forecast as a percentage.
Calculate a simple moving average demand forecast by averaging the last N periods. Smooth out noise and project the next period's demand.
Calculate Mean Squared Error to measure forecast accuracy. Penalize large forecast deviations more heavily by squaring each period's error.
Calculate seasonal indices to adjust demand forecasts for seasonal patterns. Compute seasonal factors and deseasonalized base demand for any period.
Calculate demand forecasts using a weighted moving average. Assign custom weights to recent periods for more responsive demand projections.
Classify inventory items by demand variability using coefficient of variation. X is stable, Y is moderate, Z is highly variable.
