What is Install-to-subscribe rate?

Definition, examples, and more

Definition

The percentage of users who install the app and ultimately start a paid subscription. This is a key funnel metric for evaluating onboarding effectiveness, paywall performance, and the overall value proposition.

How to Calculate

Install-to-Subscribe Rate = (New Paid Subscribers / Total New Installs) x 100. For a specific time window: 60-Day Install-to-Subscribe = Subscribers within 60 Days of Install / Installs in Cohort x 100. Revenue per Install = Install-to-Subscribe Rate x Average Revenue per Subscriber.

Example

A workout app gets 40,000 installs in January. By February 28th, 3,200 of those users have become paying subscribers, giving a 60-day install-to-subscribe rate of 8%. Segmented by source: organic installs convert at 12%, Apple Search Ads at 10%, and Facebook at 4%. This informs their budget allocation for March.

Why Install-to-subscribe rate Matters

Install-to-subscribe rate is the single most important metric connecting your acquisition and monetization funnels. A meditation app had a strong 5% rate but wanted more. Through systematic optimization — better onboarding (added 1.5%), improved paywall copy (added 0.8%), and trial length testing (added 0.7%) — they reached 8%. That 3-point improvement meant 1,200 additional subscribers per month from the same install volume, worth $144K in annual revenue.

Frequently Asked Questions

What is a good install-to-subscribe rate?

For apps with free trials, 5-15% is typical for the best performers. For hard paywall apps, 15-30% is possible. For freemium apps without trials, 2-5% is common. The benchmark depends heavily on your monetization model, app category, and traffic quality. Focus on your own trend line — even small improvements compound significantly.

How quickly should users convert after install?

Most conversions happen within the first 24-48 hours or not at all. Apps with onboarding paywalls see 60-70% of total conversions on day 0. Apps with trials see a spike at trial end. After 30 days, the probability of an un-subscribed user converting drops below 5%. This is why first-session experience is so critical.

How do I improve my install-to-subscribe rate?

Optimize each step: reduce onboarding drop-off (fewer steps, faster value), improve paywall conversion (better copy, pricing anchoring, social proof), offer appropriate trials (7-day works for most), and ensure your ad creative sets accurate expectations. A mismatch between ad promise and app reality is the number one killer of install-to-subscribe rates.
