Occasionally, I am asked what to do with a startup product, brand, or channel. In other words, you launch a new product, and after four months, you want to get an idea what the annual retention rate might be for customers purchasing from this new product.
This is where you use a life table to guess at what might happen.
The life table tells you the probability of a customer purchasing again in your embryonic product line. Once you have the details, you estimate the corresponding annual rate.
Later, I'll include a case study on this topic.
