How to measure forecast accuracy?

3. MAPE MAPE is one of the most common methods to measure forecast accuracy. It means Mean Absolute Percentage Error and it measures the percentage error of the forecast in relation to the actual values. As it calculates the average error over time or different products, it doesn’t differentiate between them.

How do you calculate MAPE?

The formula to calculate MAPE is as follows: MAPE = (1/n) * Σ (|actual – forecast| / |actual|) * 100. where: Σ – a fancy symbol that means “sum”. n – sample size. actual – the actual data value. forecast – the forecasted data value. MAPE is commonly used because it’s easy to interpret and easy to explain.

What is forecast accuracy in the supply chain?

Forecast accuracy at the SKU level is critical for proper allocation of resources. When we talk about forecast accuracy in the supply chain, we typically have one measure in mind namely, the Mean Absolute Percent Error or MAPE.

Is it possible to change MAPE to 0?

You cannot just change Inf to 0 and expect the results to make any sense. An infinite MAPE is one of the problems that can arise with MAPEs. Use alternative measures of accuracy when this problem arises. MASE is one alternative (mean absolute scaled error), described here.
