How much should you be spending to acquire a new user or customer? It’s one of the most common questions in growth marketing, and the answer depends heavily on your industry, platform, and business model. Average user acquisition cost has been rising steadily across nearly every sector, with some estimates suggesting a 222% increase over the past eight years. For mobile app teams in particular, understanding where your costs stand relative to the market is essential for planning budgets, evaluating channels, and knowing when to invest more in organic growth.
In this article, we’ll explain what acquisition cost means, share benchmark data across industries and mobile app categories, and cover practical ways to bring those costs down.
What is customer acquisition cost?
Customer acquisition cost (CAC) is broadly defined as the total amount a company spends on sales and marketing to acquire a new paying customer over a given period. The formula is straightforward: divide your total sales and marketing spend by the number of new customers acquired in that same period.
For mobile apps, a closely related metric is cost per install (CPI), which measures how much it costs to generate a single app download through paid advertising. CPI is narrower than CAC because it only counts the install, not whether that user goes on to subscribe, make a purchase, or become a paying customer. Both metrics are useful, but they answer different questions. CPI tells you how efficiently your ads are generating downloads. CAC tells you how efficiently your entire growth operation is converting spend into revenue.
A widely used benchmark for evaluating whether your CAC is healthy is the LTV to CAC ratio, where LTV is the lifetime value of a customer. Most sustainable businesses aim for a ratio of at least 3:1, meaning each customer generates at least three times what it cost to acquire them.
Average acquisition costs by industry
Acquisition costs vary dramatically depending on the industry, business model, and whether you’re acquiring through organic or paid channels. Here are some general benchmarks based on recent data:
| Industry | Average CAC |
| B2B SaaS (overall) | ~$702 |
| B2B SaaS (recent trend) | ~$1,200 |
| Fintech / Financial Services | ~$1,450 |
| Higher Education (B2B) | ~$1,143 |
| E-commerce (B2B SaaS) | ~$274–$299 |
| B2C E-commerce | ~$10–$150 |
| Healthcare | ~$15–$200+ |
| Banking | ~$20–$150 |
Sources: Userpilot, First Page Sage, GTM 80/20, Venturz.
A few patterns stand out here. B2B companies with longer sales cycles and higher contract values (especially in fintech and enterprise SaaS) tend to have the highest CAC. E-commerce and consumer businesses generally have lower acquisition costs, but they also operate on thinner margins, which means even a modest CAC increase can affect profitability.
It’s also worth noting that organic acquisition consistently costs less than paid. For B2B SaaS, organic channels like SEO and content marketing can reduce CAC to as low as $480–$942 per customer, compared to an average of $802 for paid search. Over time, organic costs tend to decrease further as content compounds, while paid costs typically rise as competition increases.
Mobile app acquisition costs
For mobile apps specifically, the key metric is cost per install (CPI). According to data from Mapendo and Business of Apps, CPI varies significantly by app category and platform:
| App Category | Approximate CPI |
| Finance / Fintech | ~$8.70 |
| Gaming (overall) | ~$3.90 |
| Gaming (Hardcore, iOS) | ~$6.00 |
| Gaming (Puzzle, iOS) | ~$3.00 |
| Gaming (Hyper-Casual) | Lower end of range |
| E-commerce / Retail | Moderate, spikes seasonally |
Sources: Mapendo, Business of Apps.
A few things to note here again. iOS consistently costs more than Android across every category. Business of Apps reports that a mid-core game install on iOS averages around $4.50 compared to $3.25 on Android. Geography also matters: CPI in the US averages around $5.30, while emerging markets in Latin America and Southeast Asia can offer CPIs as low as $0.50–$2.00.
For mobile teams, CPI is only part of the picture. What matters more is the cost of acquiring a user who actually stays, subscribes, or makes a purchase. That’s why retention and conversion optimization are just as important as acquisition spend, and why investing in organic channels like ASO can have a significant impact on overall unit economics. Understanding the average cost of acquisition for your specific app category and platform is essential for setting realistic budgets.
How to reduce acquisition costs
Regardless of industry, there are a few approaches that consistently help bring acquisition costs down:
Invest in organic channels. SEO, content marketing, and App Store Optimization (ASO) all build visibility over time without requiring ongoing ad spend for each new user. For mobile apps, ASO is one of the most effective ways to reduce reliance on paid installs, since the majority of app downloads still originate from app store search.
Improve conversion rates. Often, the fastest way to reduce CAC isn’t to spend less on acquisition but to convert more of the users you’re already reaching. For mobile apps, this can mean testing store listing creative assets (icons, screenshots, descriptions) to improve install rates, or refining onboarding flows to increase the percentage of installers who become active users.
Focus on retention. Acquiring a new customer costs 5 to 25 times more than retaining an existing one. For subscription apps and SaaS businesses, improving retention by even a few percentage points can have a meaningful effect on the LTV to CAC ratio, making the same acquisition spend more efficient.
Use first-party data. Companies that have built strong first-party data systems report 34% lower average CAC compared to those still relying primarily on third-party targeting. Understanding your existing users well enough to find more people like them is one of the most reliable paths to more efficient acquisition.
What’s next
Acquisition costs are unlikely to come down on their own. Competition is increasing, privacy regulations are limiting targeting options, and ad platforms are becoming more expensive. The companies that manage their CAC well in 2026 and beyond will be those that balance paid acquisition with strong organic channels, invest in conversion and retention alongside top-of-funnel spend, and use their own data to make smarter decisions about where to allocate budget.

FAQ
What is the average customer acquisition cost?
It varies widely by industry. B2B SaaS companies average around $702–$1,200 per customer, fintech companies around $1,450, and e-commerce businesses as low as $10–$299 depending on the model. For mobile apps, cost per install typically ranges from $1.50 to $5.00, though finance and hardcore gaming apps can be significantly higher.
What is cost per install (CPI)?
CPI is the amount an advertiser pays each time a user clicks on an ad and installs an app. It’s the most common acquisition metric in mobile marketing. CPI varies by app category, platform (iOS is typically more expensive than Android), and geography.
What is a good LTV to CAC ratio?
Most sustainable businesses aim for at least 3:1, meaning each customer generates three times more revenue over their lifetime than it cost to acquire them. Ratios below 2:1 generally indicate a problem, while top performers in certain industries achieve 5:1 or higher.
How can I reduce my customer acquisition cost?
The most effective approaches include investing in organic channels (SEO, ASO, content marketing), improving conversion rates at each stage of the funnel, focusing on retention to increase customer lifetime value, and using first-party data for more precise targeting.
Why is acquisition cost rising?
Several factors are contributing: increased competition for ad space, privacy changes (like Apple’s ATT) that limit targeting precision, rising ad platform costs, and market saturation in many app categories. These trends are pushing more companies to invest in organic growth and retention as a way to offset rising paid acquisition costs.
