Rewarded Ads vs Interstitials: 2026 eCPM Benchmarks for Mobile Game Publishers

PGP Studio Team · July 13, 2026 · 8 min read

Rewarded video clears $15–$40 eCPM vs under $2 for banners. The real 2026 numbers behind ad format strategy for mobile games.

Per AppLovin's publisher benchmarks, rewarded video clears 15 to 40 dollars eCPM in Tier-1 markets, compared to under 2 dollars for banners and 5 to 15 dollars for interstitials. Tenjin's 2026 Ad Monetization Benchmark Report puts US rewarded video eCPM specifically at 16.49 dollars on Android and 19.63 dollars on iOS. Laid out side by side like that, the gap between rewarded video and every other standard ad format is not a marginal difference in monetization efficiency, it is close to an order of magnitude relative to banners, and a meaningful multiple relative to interstitials, which is exactly the kind of gap that should be actively shaping a studio's format strategy rather than sitting as an interesting statistic in an industry report nobody actually acts on.

Why the Gap Is This Large

The underlying reason rewarded video commands such a large eCPM premium is straightforward once you think about it from the advertiser's side of the transaction rather than only the publisher's side: a rewarded ad is, by design, a fully voluntary, high-attention engagement. The player chooses to watch it, in exchange for a specific, understood reward, and is considerably more likely to actually watch the full creative attentively rather than immediately looking for a skip button or a close icon the moment one appears, the way a player typically behaves toward an interstitial they did not choose to see. Advertisers pay a premium for that voluntary, high-attention engagement because it converts meaningfully better than an interruption ad a player is actively trying to dismiss as quickly as possible, and that better conversion rate for the advertiser is what supports the higher eCPM a publisher can command for the same ad slot.

Offerwalls: A High Number With an Important Asterisk

Offerwalls sit in a different tier entirely, an average eCPM around 530 dollars, a figure that looks almost implausible next to the rewarded and interstitial numbers above until you understand the important asterisk attached to it: far lower fill rates and engagement than standard formats. Offerwalls typically monetize through a small number of players completing a considerably more involved action, installing and using another app, completing a survey, reaching a specific milestone in a partner app, rather than the simple thirty-second video view that drives rewarded video's much higher volume. That combination of a very high per-completion payout and a much lower completion rate is exactly why offerwalls function as a supplement layered on top of a primary monetization strategy, not a primary format on their own; the headline eCPM number is real, but it describes a format most players will never actually engage with at all, rather than one every player sees regularly the way a rewarded or interstitial slot typically does.

Network Share and What It Signals About Where to Focus Integration Effort

On network share specifically, Google AdMob holds roughly 28 percent of the Android market, AppLovin about 24 percent, and ironSource around 5 percent, a distribution broadly consistent with the network comparisons Teqblaze and other mediation platforms publish. Android also generated 57 percent of ad revenue share in Q1 2026 versus 43 percent for iOS. That network share distribution matters directly for a practical, tactical decision every studio faces: which mediation networks are worth the integration and testing overhead to include in a waterfall or bidding setup, versus which are a low-value addition that adds integration complexity without meaningfully improving fill rate or eCPM given how concentrated the market actually is among the top handful of networks.

For a small studio without a dedicated ad monetization specialist on staff, our practical recommendation is to prioritize deep, well-tuned integration with the top two or three networks by share rather than spreading integration effort thin across a long tail of smaller networks each contributing a marginal fill rate improvement. A well-tuned integration with AdMob and AppLovin specifically, given their combined roughly 52 percent share of the Android market alone, captures the large majority of the addressable inventory value with meaningfully less ongoing integration and testing overhead than chasing every available network in a maximally fragmented waterfall.

The Android-Versus-iOS Revenue Split, and Why It's Closer Than Assumed

The 57-43 revenue split favoring Android over iOS in Q1 2026 is worth noting specifically because it runs counter to a common industry assumption that iOS users, generally understood to skew toward higher discretionary spending on average, would dominate ad revenue share by a wider margin than this data actually shows. A 57-43 split is a meaningful Android lean, but it is considerably closer to parity than the iOS-premium narrative that dominates a lot of general mobile monetization discussion would suggest, and that closer-than-expected split is worth factoring into how a studio weights platform-specific optimization effort rather than assuming iOS ad monetization automatically deserves a disproportionate share of attention purely based on the platform's premium-audience reputation.

The Player Experience Argument, Not Just the Revenue Argument

For our own puzzle and arcade titles specifically, this data argues for a rewarded-first hybrid strategy, offering an optional rewarded ad for extra moves or a revive, rather than defaulting to interstitial-heavy monetization between every level. It is worth being explicit that this recommendation is not purely a revenue-maximization argument, even though the eCPM data alone would support it on financial grounds. A rewarded-first approach is also, independently, a better player experience: an ad the player actively chooses to watch in exchange for a specific, understood benefit is a fundamentally different experience than an ad forced on the player at a moment they did not choose, and the fact that the better player experience and the better monetization outcome point in the same direction here removes what is normally a genuine tradeoff a studio has to weigh and make explicit rather than a case where one goal has to be sacrificed for the other.

Where Interstitials Still Earn a Place

None of this argues for eliminating interstitials entirely from a monetization strategy, and it is worth being precise about where they still earn a legitimate place rather than treating the eCPM comparison as a blanket case against the format. Interstitials placed at genuinely natural break points in a session, a level completion screen, a return-to-menu moment, a session-end point the player was already treating as a pause rather than an active play moment, do not carry the same player experience cost as an interstitial interrupting active gameplay mid-session. The eCPM gap between rewarded and interstitial formats is real, but interstitials placed thoughtfully at natural pauses remain a legitimate supplementary format worth keeping in a well-designed monetization strategy, specifically for the segment of players who choose not to engage with rewarded ad prompts at all and would otherwise generate no ad revenue whatsoever from a rewarded-only approach.

How We're Applying This Across Our Own Catalog

Across our own catalog, we are actively auditing every title's current ad placement strategy against this exact framework: rewarded video as the primary format wherever a natural, player-beneficial reward moment exists in the core loop, well-placed interstitials at genuine natural break points as a supplementary format rather than the primary one, and offerwalls reserved as a small, optional supplementary layer for the minority of players willing to engage with a more involved completion action. That audit has already identified more than one title in our catalog defaulting to a heavier interstitial cadence than the current eCPM data actually supports, and rebalancing toward a more rewarded-forward mix is one of the more straightforward, low-risk monetization improvements available to us this year, precisely because it improves both the revenue side and the player experience side of the equation simultaneously rather than trading one off against the other.

Testing Frequency and Cadence, Not Just Format

Beyond the format decision covered above, the frequency and cadence of rewarded ad prompts specifically deserves its own testing discipline, since a rewarded ad offered too frequently or in a context that feels manipulative rather than genuinely optional can undermine the exact voluntary, high-trust dynamic that makes the format monetize as well as it does in the first place. We A/B test rewarded ad placement frequency explicitly across our catalog rather than assuming a single fixed cadence works identically across every title and every point in a title's lifecycle, since player tolerance for ad frequency shifts as a title matures and its player base's expectations settle into a specific rhythm.

What This Means for New Titles From Day One

For any new title we scope now, ad format strategy is designed into the core loop from the earliest prototyping stage, identifying natural, player-beneficial reward moments where a rewarded ad genuinely fits the game's own reward structure, rather than retrofitting ad placements onto an already-finished core loop as a late-stage monetization pass. That earlier integration consistently produces placements that feel native to the game's own systems rather than bolted on, which is itself part of why the player-experience and revenue arguments discussed throughout this piece tend to align rather than conflict when ad strategy is designed in early.

Watching for Diminishing Returns as Rewarded Ads Become More Common

One trend worth watching honestly rather than assuming today's eCPM premium holds indefinitely: as more studios shift toward rewarded-first strategies in response to exactly this kind of data, rewarded ad supply increases industry-wide, and basic supply-and-demand dynamics suggest that could compress the current premium over time even if underlying advertiser willingness to pay for high-attention engagement stays constant. We are not seeing that compression meaningfully yet as of 2026, but a rewarded-first strategy built assuming today's exact eCPM gap holds forever, rather than treating it as a currently favorable but not guaranteed-permanent condition, would be planning on a less solid foundation than the current data actually supports.

Segmenting Strategy by Player Lifecycle Stage

Beyond the format-level strategy discussed throughout this piece, we have found real value in varying ad strategy by where a specific player sits in their own lifecycle with a title, a brand new player in their first session, a returning player several weeks in, a long-tenured veteran player, rather than applying one uniform ad strategy identically across every player regardless of tenure. A brand new player in their onboarding window gets zero ads at all, consistent with the FTUE principles covered elsewhere in our own coverage, while a longer-tenured player who has already demonstrated sustained engagement can typically tolerate a somewhat higher ad frequency without the same retention risk a newer, less-committed player would face from the identical frequency. We will keep revisiting this specific eCPM comparison roughly twice a year, since ad monetization benchmarks in mobile gaming shift meaningfully faster than most other data cited in our coverage, and a rewarded-first strategy built on stale eCPM assumptions is a real risk worth actively guarding against. Our standing practice going forward is to re-audit every title's ad placement mix against fresh eCPM data at least twice a year, treating monetization configuration as a living decision to keep tuned rather than a one-time launch setting left untouched for a title's entire lifecycle.

The broader monetization strategy this specific format data feeds into is covered in our Hyper-Casual Monetization in 2026 guide. Decisions like these get made with real numbers, documented on our case studies page, not just described in the abstract here.
