Average sub box churn is 5–10%/month.
Churn is the killer
Even a small reduction in monthly churn has an outsized impact on LTV. A box business at 5% monthly churn is nearly twice as valuable per subscriber as one at 10% — even if prices and margins are identical.
LTV math
- Average lifetime = 1 ÷ monthly churn rate
- LTV = box price × average lifetime
- At 8% churn: ~12.5 months avg lifetime
- At 5% churn: ~20 months avg lifetime
Retention tactics
Offer a prepay discount (3 or 6 months), add a loyalty streak reward, and email subscribers at the 2-month mark before they hit common cancellation windows. Curated surprise items also reduce cancellation intent.
