Subscription revenue is not subscription profit. Card declines, dunning tooling, and support load change the true net of a WooCommerce subscription program in ways monthly recurring revenue alone never shows.

## MRR hides the costs

Subscription plugins report a growing recurring revenue number while rarely surfacing failed-payment recovery cost, the price of dunning email tooling, or the volume of support tickets subscriptions generate on their own.

## What to net out

Involuntary churn from card declines, the cost of dunning and win-back tooling, refund and pause requests, and plugin license fees that scale with subscriber count as the program grows.

## A healthier metric to track

Net subscription contribution margin: MRR minus payment failure losses, support cost, and tooling spend, reviewed monthly alongside gross MRR growth rather than in place of it.

## FAQ

**What is a normal involuntary churn rate?**

It varies by processor and card mix, but any month-over-month increase deserves investigation before it gets attributed to "the market."

**Do subscription discounts pay for themselves?**

Only if they raise net subscription contribution margin, not just retention rate—model the discount cost against the churn reduction it actually produces.
