ARPDAU blends the two things every publisher cares about, how well you monetize and how engaged your users are, into a single number you can read every morning. It sits between the fast, placement-level view of eCPM and the slow, lifetime view of LTV, which is why monetization teams treat it as their daily pulse. When you ship a new placement or run a live event, ARPDAU is usually the first number that tells you whether it worked.

How to calculate ARPDAU

ARPDAU = Total revenue for the day / Daily Active Users (DAU) for the day

Revenue here usually includes everything: in-app purchases, ad revenue, offerwall earnings, and subscriptions. The denominator is your DAU for that same day, so both halves of the fraction cover the exact same 24 hours.

A worked example

If your app earns $4,000 in a day and has 50,000 daily active users:

That is 8 cents per active user, per day. On its own the figure looks tiny, but read across a month of active users it is the number that decides whether your monetization is climbing or stalling.

What counts as a good ARPDAU?

There is no universal benchmark. It swings widely by genre, geography, and business model.

• Hypercasual games often sit at a few cents, ad-heavy with huge volume.

• Hardcore and social casino titles can run several dollars per user.

• Geography moves the average: high-spending markets lift it well above developing ones.

The number that matters most is your own ARPDAU over time, and whether it is trending up. Comparing your casual puzzle app to someone else's poker title tells you almost nothing.

ARPDAU vs. ARPU vs. eCPM

ARPU measures revenue per user over a longer window, a month or the full lifetime, so it answers what a user is ultimately worth. ARPDAU narrows that to a single day, which makes it far more responsive to changes you ship this week. eCPM is narrower still: it measures earnings per 1,000 impressions for one ad source, not revenue across every channel. Read together, eCPM tells you which placement is efficient, ARPDAU tells you whether each active user is worth more today, and ARPU tells you what it adds up to over time.

How to improve ARPDAU

• Add or optimize revenue streams, for example layering an offerwall on top of ads and IAP.

• Improve ad placement, frequency, and eCPM without crowding the experience.

• Segment your users so the right offers reach the right people.

• Lift engagement so more of your DAU actually convert.

ARPDAU and offerwalls

Because ARPDAU counts revenue from every source, adding a high-value channel raises it directly. An offerwall earns on completed offers rather than passive views, so a single motivated user can contribute more in a day than many banner impressions. It also reaches the non-paying majority of your DAU, users who would otherwise add nothing to the numerator. RevU's offerwall matches offers to users so more of those daily sessions turn into completions, which shows up as a higher blended ARPDAU rather than a spike in any one placement.

Common mistakes to avoid

• Reading ARPDAU without DAU beside it. A rising ARPDAU on a shrinking audience can still mean falling revenue.

• Comparing across genres or regions as if they were equivalent.

• Chasing ARPDAU by cramming in ads, which lifts the daily number while driving the churn that erodes LTV.
