How to calculate subscription box profit margin
Gross profit per box starts with your selling price and subtracts every unit cost: product, packaging, inbound freight, outbound shipping, fulfillment labor, spoilage, and platform fees. The result is the amount that actually supports your business.
Once you know gross profit, you can estimate MRR, LTV, CAC payback, and break-even subscribers. That gives you a better answer than revenue alone ever could.
How churn affects the math
Churn quietly erodes every recurring business. Even a good product can struggle if the retention curve is weak. The churn calculator shows the subscriber loss over 12 months so you can see the effect before it compounds.
