# What Is Trial Conversion?

> Trial conversion is the rate at which free-trial users become paying customers — a core product-led growth metric tying acquisition to revenue.

**Trial conversion** is the percentage of users on a free trial who convert to paid subscriptions or contracts within a defined window.

### How it works

PLG companies track trial conversion by cohort: signup week, traffic source, plan type, and sales-assist vs pure self-serve. Formula: paying customers from trial cohort divided by trial starters (often excluding fraud and duplicate accounts). Windows vary — 14-day trial conversion at day 30 vs day 14 tells different stories.

Improvements come from shorter [time to value](/glossary/time-to-value), in-product onboarding, sales outreach for high-intent accounts, and pricing clarity. [Usage-based pricing](/glossary/usage-based-pricing) products may skip classic trials in favor of freemium with upgrade triggers — conversion metrics adapt accordingly.

Investors segment conversion: enterprise trials with POC success criteria behave differently from credit-card-required SMB trials.

### Why it matters

- **Founders:** Optimize one funnel step at a time — activation before paywall, not more top-of-funnel spend alone.
- **Investors:** Trial conversion × trial volume × ARPA models revenue efficiency. Falling conversion with rising spend is a red flag.

### Common mistake

Reporting conversion on all signups instead of qualified trials that reached activation. Including users who never logged in inflates denominators and hides product gaps.

## FAQ

### What is trial conversion in simple terms?

Trial conversion measures how many people who start a free trial actually pay when the trial ends. If 100 start and 20 subscribe, trial conversion is 20%.

### Why does trial conversion matter?

Low conversion means you are buying traffic that never monetizes. VCs compare conversion across cohorts and plans to see if product delivers value before the paywall hits.
