How the numbers shift across typical situations for this calculator:
| Scenario | Subscription box margin | Markup | Profit per box |
|---|---|---|---|
| $50 box · $30 cost | 40.00% | 66.67% | $20.00 |
| $25 box · $18 cost | 28.00% | 38.89% | $7.00 |
| $120 box · $55 cost | 54.17% | 118.18% | $65.00 |
| $35 box · $38 cost (loss) | -8.57% | -7.89% | -$3.00 |
How This Calculator Works
Enter monthly revenue per box and the all-in fulfilled cost per box (product, packaging, fulfillment, shipping, payment processing). The calculator subtracts cost from revenue for profit per box and divides by revenue for margin.
The Formula
Profit Margin and Markup
Markup = (Revenue − Cost) / Cost × 100 — the same profit measured against cost instead of revenue
Worked Example
A $50-a-month box at a $30 fulfilled cost posts a 40% gross margin and $20 of profit per box. After customer acquisition (often $40 to $80 per subscriber) and retention churn, that $20 needs roughly 3 to 5 months of survival to recover acquisition spend — common in the category.
Key Insight
Subscription box margins live or die on cost discipline. The headline 40% to 50% gross margins of category leaders depend on direct supplier relationships, optimized packaging, and shipping deals — not on raising the box price. Most boxes that fail do so because cost-of-goods crept up while the price stayed the same.

Frequently Asked Questions
How is subscription box margin calculated?
Subtract fulfilled cost per box from monthly revenue per box, then divide by revenue. A $50 box at $30 cost is a $20 profit per box and a 40% gross margin.
What goes into fulfilled cost?
Product cost, packaging (box, filler, inserts), fulfillment labor, shipping, and payment processing fees. Some teams also include free-trial and replacement-shipment costs.
What is a healthy subscription box margin?
Category leaders often run 40% to 55% gross margin per box. Below 30% is a sign that either price needs to rise, cost needs to fall, or volume needs to grow enough to renegotiate supplier terms.
Should I include customer acquisition cost?
Not in gross margin — CAC sits in operating costs. But CAC absolutely matters for the business model: margin per box × expected retention months must exceed CAC for the subscription to be profitable at the unit level.
How do top boxes improve margin?
Direct manufacturer relationships, branded packaging that doubles as marketing, shipping consolidation, and tiered prices that move the average customer upward. Most retail-priced inputs are 30% to 50% cheaper at scale.
When is this calculator unreliable?
Less reliable when product cost varies by box theme/curation, when cohort CAC vs blended differs (early cohorts substantial different), when churn timing affects (early churn substantial CAC unrecoverable), when prepay annual discount distortion (immediate payback effect), when returns/refunds not netted, when influencer/PR seeded boxes count as revenue, or when acquisition vs retention spend split unclear. CAC payback <6 months ideal but challenging — annual prepay substantial.

Substantial CAC payback critical. RELIABILITY: Reliable for documented box-level P&L.
