Birch Box their COGS (cost of goods sold) at $5.85 ($3.35 in product & packaging, $2.50 in shipping & fulfillment).


What is Birchbox’s Monthly Churn Rate?

This was originally an answer I posted on Quora in response to the question: What is Birchbox’s Monthly Churn Rate?
I’m estimating that their churn is approximately 8 or 9%. I suspect it started very low (near 5% in 2011/2012) and has slowly ramped up as they have reached serious scale (now, 55 months in to being live). Obviously, this is just an intelligent guess, but I think it makes sense.
With subscriptions at such a low price point, maintaining a churn of < 10% should be relatively doable if the product offering is decent. Theirs is decent. This gels with the churn we’re seeing on Cratejoy subscriptions for beauty products with a low price point. With a churn much higher than that, they would need to add absolutely ridiculous numbers of subscribers per month.
I have a bit of insider information from some fortunate lunches with an early employee that corroborates the < 10% churn as well as some of the COGS assumptions I make below.
I created the model using a modified version of the output from the subscription box business calculator.
I used the following datapoints for my estimate:
I also estimated their COGS (cost of goods sold) at $5.85 ($3.35 in product & packaging, $2.50 in shipping & fulfillment).
I built the model by using the subscription box calculator on Cratejoy. I downloaded it to excel and tweaked it from there until it matched the datapoint on subscriber counts and roughly made sense.
