Walter - dropout would be entirely those customers who cancel the service, those you drop would be classed differently.
There are two distinct areas of drop out, the largest proportion would be in the first 3 cleans, where for whatever reason a customer took on the service and then dropped it, ( this is to be expected ) then the established customer drop out, IMO it should be very low, because the customer has proved they want service, the only loses now come from, financial changes, house moves, death or personal circumstances. All of these are unavoidable and openly communicated by the customer ( except death!! ) if your getting regular dropouts of customers you've had for more than 3 cleans then ask yourself some questions, is my clean as good as it could be? - am I providing a timely service ? - are my customer service skills acceptable ?

OK, I'm with you now.
Excluding the ones that I choose to drop then.
Early drop out rate (within 4 cleans) is very low. It does happen of course. I normally retain customers for the longer term but maybe 5% stop within 4 cleans. There are spikes to this. When the economy was struggling around 2008 - 2011 a lot of people lost their jobs/had pay cuts/overtime and bonuses cut - so it did increase for a while.
Losing a long term customer is pretty unusual. OK, so people move or die. I've also lost them when retiring, as it means a hefty income reduction for many - or they now have time to do the cleaning themselves.
Like everyone else though (I imagine), I do get a very occasional mystery cancellation from a long term customer.
Overall, I'm happy with my retention rate.
EDIT: I did get a spike in drop outs when switching to WFP in 2005. Although I primed the customers, I wasn't aware of any other residential window cleaners in the area using WFP. This made it appear that I was a bit of a maverick because few customers had seen it.
I prepared the ground for the switch but it was still too big a leap for some of them.
Unlike some window cleaners, I wasn't prepared to mess about blading off de-ionised water from the ground floor windows etc. I had to be firm for the longer term viability of my business, so I was prepared to take short term hits to achieve this.
