E-commerce Mobile App ROI: Key 2026 Figures

Conversion rate: mobile app vs mobile web

The conversion rate differential is the first pillar of mobile app ROI in e-commerce. According to Criteo data, retail apps convert more than 3 times better than mobile web. BuildFire confirms a 157% higher conversion rate on apps compared to mobile sites, with users adding more products to cart and browsing more product pages per session.

In concrete numbers: the average e-commerce app conversion rate is around 6%, versus 1.5 to 2% on mobile web. For a retailer with 100,000 monthly mobile visitors and a 60-euro average order value, this represents a substantial revenue differential as soon as 20 to 30% of traffic migrates to the app.

• →E-commerce app conversion: ~6% on average (Criteo, BuildFire)
• →Mobile web conversion: 1.5 to 2% on average
• →Multiplier factor: 3x to 4x depending on vertical
• →Retail apps account for 70% of m-commerce transactions for brands that have one (Criteo)

Average order value (AOV): the app effect on spend per order

The second lever of mobile app return on investment is the increase in average order value. Data compiled by MobiLoud shows that app users spend around $95 per order compared to $73 on the website, a gap of roughly 30%. Other studies place the AOV gain between 10 and 30% depending on the vertical.

This phenomenon is driven by the fluidity of native checkout, real-time personalization (product recommendations, bundles) and the reduction of technical friction (pre-filled data, integrated Apple Pay / Google Pay). The travel accessories brand BEIS has documented a 19% higher AOV on its app compared to mobile web.

• →App AOV: ~$95 on average vs ~$73 on web (MobiLoud)
• →Average gain: +10 to 30% depending on vertical
• →Native checkout reduces friction and drives basket size up
• →Real-world case BEIS: +19% AOV on app vs mobile web

Retention and customer lifetime value (LTV): the long-term multiplier

This is where mobile app ROI becomes exponential. Customer lifetime value for app users is 2.8 to 5 times higher than web-only shoppers. 60% of first-time app buyers make at least a second purchase, and app users buy on average 33% more frequently than non-app users.

Brands with a native mobile app see repeat purchase rates up to 50% higher than those without one. Since acquiring a new customer costs 5 times more than retaining an existing one, the app channel is a structural profitability lever.

• →App user LTV: 2.8 to 5x higher than web users (MobiLoud, Venn Apps)
• →60% of first-time app buyers make at least a 2nd purchase
• →Purchase frequency: +33% for app users
• →Repeat purchase rate: up to +50% with a native app

Push notifications: the most underrated ROI lever

Push notifications are the cheapest and most effective re-engagement channel on the market. According to Business of Apps and Pushwoosh, the average e-commerce opt-in rate reaches 68% (75% on Android, 52% on iOS). The average reaction rate is 7.8% across platforms, with significantly higher peaks for personalized notifications.

Abandoned cart push notifications have a 16% click rate, and roughly 28% of app users who click on a notification end up making a purchase. The overall push notification ROI can reach 2,200% according to studies compiled by Gitnux. The marginal cost of a push is a few cents, versus several euros for Meta or Google retargeting.

• →E-commerce push opt-in: 68% on average (Business of Apps)
• →Cart abandonment push click rate: 16% (MoEngage)
• →28% of push clickers end up purchasing
• →Push notification ROI: up to 2,200% (Gitnux)
• →Marginal push cost: a few cents vs several euros in paid media

How to calculate your e-commerce mobile app ROI

The baseline ROI formula for an e-commerce mobile app rests on three measurable components:

1. Conversion gain: (App visitors x app conversion rate) - (App visitors x mobile web conversion rate) x Average order value

2. AOV gain: Number of app orders x (App AOV - Web AOV)

3. Re-acquisition savings: Number of push-driven returns x (Avoided retargeting CPA)

A concrete example: a fashion retailer with 80,000 mobile visitors/month, 65-euro average order, with 25% migrating to the app — the conversion gain alone represents ~47,000 euros/month in additional revenue. Adding the AOV uplift (+15%) and push savings (estimated at 8,000 euros/month in saved retargeting budget), the annual ROI far exceeds the cost of a solution like ConvertNative.

• →Step 1: Quantify the conversion differential (3x average)
• →Step 2: Estimate the AOV gain (+10 to 30%)
• →Step 3: Calculate re-acquisition savings via push
• →Step 4: Compare against total cost of ownership (subscription + maintenance)
• →Average payback period: 6 to 18 months (OptiBlack, DevTrust)

Apps contribute 20 to 60% of online revenue from less than 15% of users

A little-known fact perfectly illustrates mobile app profitability: brands with an app see it contribute 20 to 60% of their online revenue, even though it often represents only 10 to 15% of their user base. This asymmetric ratio is explained by the combination of the three factors above: higher conversion, larger basket, and multiplied return frequency.

Mobile commerce reached $4.5 trillion in 2024, representing 70% of global e-commerce. Apps alone are projected to contribute $3.9 trillion by 2029 according to AppVerticals projections. Not investing in the app channel means ignoring the highest-performing sales channel per user.

• →20 to 60% of online revenue comes from the app, from <15% of users (MobiLoud)
• →M-commerce accounts for 70 to 78% of global e-commerce transactions
• →Revenue per app user: 7x higher than web (MobiLoud)
• →Projection: $3.9T in in-app transactions by 2029 (AppVerticals)

ROI checklist before launching your mobile app

Before investing, verify that your business meets the conditions for a fast ROI:

• →Mobile traffic: at least 30,000 unique mobile visitors per month
• →Average order value: above 40 euros (below that, ROI depends on purchase frequency)
• →Purchase frequency: at least 2 to 3 purchases/year per customer (ideally monthly)
• →Existing customer base: at least 10,000 email/SMS contacts for app launch
• →Content capacity: team able to maintain push notifications (1 to 3/week)
• →If you check 4 out of 5 criteria, ROI is near-certain within 12 months
