# Re-completion Rate

## Re-completion Rate

A metric that tracks the rate at which a customer, **having completed a task once**, completes the *same kind* of task a **second time within its natural recurrence window**.

It is the antithesis of first-transaction metrics — signups, free-trial conversions, app installs — which only measure **novelty** and initial capability demonstrations.

### Natural recurrence windows vary by industry
- **Days** — food delivery
- **Weeks** — travel
- **Months** — specialized professional tasks

If a product's re-completion rate within *its specific window* falls below the category baseline, the company has built a **"one-off" experience** rather than a habit. Optimizing for this metric requires shifting product roadmaps toward features that increase the probability of return usage: **speed of repeat tasks, memory of past preferences, and anticipation of recurring needs**.

This is the lead measure of a forming [[concept-habit-moat]], the fourth step of the [[framework-habit-playbook]], and is operationalized by [[action-optimize-second-transaction]]. Its diagnostic power is illustrated by [[claim-instant-checkout-failure]], where a product won the first transaction but lost the second.
