We will have a closer look at these next. Do not let the simple appearance of these metrics fool you. After explaining the basics, we will delve into the intricacies of how the metrics are calculated in practice and show how simple and completely justifiable changes in the calculation logic has the power of radically altering the forecast accuracy results.
What is forecast bias?
Forecast bias is the difference between forecast and sales. If the forecast over-estimates sales, the forecast bias is considered positive. If the forecast under-estimates sales, the forecast bias is considered negative. If you want to examine bias as a percentage of sales, then simply divide total forecast by total sales – results of more than 100% mean that you are over-forecasting and results below 100% that you are under-forecasting.

Against this backdrop, it is important to note that there are moments when forecasting is comparatively easy—and other moments when it is impossible. The cone of uncertainty is not static; it expands and contracts as the present rolls into the future and certain possibilities come to pass while others are closed off. There are thus moments of unprecedented uncertainty when the cone broadens to a point at which the wise forecaster will demur and refrain from making a forecast at all. But even in such a moment, one can take comfort in the knowledge that things will soon settle down, and with the careful exercise of intuition, it will once again be possible to make a good forecast.
