What is good forecast accuracy?
Q: What is the minimum acceptable level of forecast accuracy? … Therefore, it is wrong to set arbitrary forecasting performance goals, such as “ Next year MAPE (mean absolute percent error) must be less than 20%. ” If demand is not forecastable to this level of accuracy, it will be impossible to achieve the goal.
How do you find the forecast error?
Another common way to work out forecast error is to calculate the Mean Absolute Deviation (MAD). This shows the deviation of forecasted demand from actual demand, in units. It takes the absolute value of forecast errors and averages them over the forecasted time periods.
