2990 total observations
This table predicts how many people stay or leave of the people you
predict to leave
This table also predicts how many people stay or leave of the people
predicted to stay
Predicted 419 to leave but only 392 of those predicted to leave
left
Predicted 2571 to stay and of those people 90 actually left
find the financial impact of the model, give the following
assumptions:
the customer retention program consists of forgiving the anual fee
of $100 (on average)
the value of a customer is $2,300 per year (on average)
customer retention programs have a 30% success rate
predicted 419 to leave
Cost $41,900
We will save 30% of 392 = 117.6, each person valued $2300 x 117.6 =
$270,480
net profit of the program is $228,580 from 2,990
Cost per customer is $79.23
