Shipping and packaging are 20.5% of the box price, which is why subscription boxes live or die on churn rather than on contents. At 9% churn a subscriber receives 11.1 boxes — the third and fourth are where the acquisition cost is actually recovered.
How the Subscription Box Profit Calculator works
Shipping and packaging typically take a fifth of a subscription box's price, which is why the model turns on churn rather than contents. At 9% monthly churn a subscriber receives eleven boxes — and the third and fourth are where the acquisition cost is actually recovered.

Frequently asked questions
What margin does a subscription box need?
Contribution per box needs to cover acquisition cost within the first few boxes. At typical churn rates that means 40% or better contribution before shipping is even considered.
Why is churn so high on boxes?
Because the novelty fades and the value is judged fresh every month. Boxes churning 8% to 12% monthly are normal, which gives a subscriber life of eight to twelve boxes.
How do I reduce box churn?
Personalisation, skip options rather than cancel-only, and a genuine sense that each box differs from the last. Skip options in particular convert cancellations into pauses.
Are annual box subscriptions worth pushing?
Strongly, for this model. They remove eleven monthly cancel decisions and fund the acquisition of the next subscriber immediately.
