Monthly Active Users

User Growth

As a subscription-based app, Duolingo generates revenue growth by expanding both its subscriber base and the amount each subscriber spends over time.

Over the last two years, Duolingo’s monthly active users, a key performance metric for the company, increased by 39.8% annually to 130.2 million in the latest quarter. This growth rate is among the fastest of any consumer internet business and indicates its offerings have significant traction.

In Q1, Duolingo added 32.6 million monthly active users, leading to 33.4% year-on-year growth. The quarterly print was lower than its two-year result, suggesting its new initiatives aren’t accelerating user growth just yet.

Revenue Per User

Average revenue per user (ARPU) is a critical metric to track because it measures how much the average user spends. ARPU is also a key indicator of how valuable its users are (and can be over time).

Duolingo’s ARPU growth has been subpar over the last two years, averaging 1.6%. This isn’t great, but the increase in monthly active users is more relevant for assessing long-term business potential. We’ll monitor the situation closely; if Duolingo tries boosting ARPU by taking a more aggressive approach to monetization, it’s unclear whether users can continue growing at the current pace.

This quarter, Duolingo’s ARPU clocked in at $1.77. It grew by 3.2% year on year, slower than its user growth.
