This KPI aims to calculate how many days of vehicle supply you are currently working with.

A) Number of days in 1 year = 365
B) Annual Stock Turn = 10.4
C) Days Supply = 35 days (A ÷ B)

This illustration is showing that if you carry on selling at your current sales rate, then you have enough stock to continue trading for 35 days.

Obviously, you do not need to carry any more stock than is absolutely necessary because that would be a total waste of your money.

When dealing with used vehicles, you need to read this page in conjunction with Stock Turn to determine the performance that you require.

This is also known as Days stock Turn.
