You built the app. You bled for it. The hard part is over, right? Wrong. Now you have to get it in front of the millions who need it. This brings you to a critical question: Should you hire a mobile app advertising agency? And if so, what will it really cost?
Let’s get one thing straight. There is no magic number. Asking for the cost of an agency is like asking for the price of a car. Are we talking about a reliable sedan or a Bugatti? The real question isn’t just “how much?” It’s “What am I paying for, and which model fits my company’s growth stage?“
We’re going to break down the models and the numbers you can use to hire mobile app marketing agencies. This is the information you need to make a smart decision. So, you can start making notes if you like.
What Are You Actually Buying?
Before we talk dollars, let’s be clear about what a good agency does. You are not just buying ads. You are purchasing a strategy and a team. This usually includes:
- App Store Optimization (ASO): This is SEO for the App Store and Google Play. It helps your app appear in search results when people look for relevant keywords.
- Paid User Acquisition (UA): This involves direct ad spending on platforms like Meta, Google, TikTok, and Apple Search Ads to drive installs.
- Creative Development: The agency designs and tests video ads and images to see what works best with your target audience.
- Analytics and Reporting: A great agency tracks key data. They watch everything from cost per install (CPI) to lifetime value (LTV) to ensure a positive return.
Beyond these core tasks, you are buying speed. An experienced agency has already navigated the learning curve you would face, allowing them to deliver results faster and more efficiently than an in-house team that is just starting out. Now, let’s see how these services are priced.

Decoding Agency Pricing Models
The top advertising agencies and smaller firms alike use a few common pricing models. Each one has its place. The right choice depends on your budget, goals, and the amount of risk you are willing to take.
| Pricing Model | How It Works | Typical Cost (2025) | Best For |
| Hourly Rate | You pay for the hours the agency works on your account. | $100 – $300+ per hour | Short-term projects or when you need an expert for a limited time. |
| Project-Based Fee | A single, fixed price for a specific, one-time project. | $5,000 – $50,000+ per project | App launches, a major ASO overhaul, or a specific campaign. |
| Monthly Retainer | You pay a fixed fee each month for ongoing services. | $5,000 – $25,000+ per month | Companies that are seeking a long-term partner for continuous growth. |
| Percentage of Ad Spend | The agency’s fee is a percentage of your monthly ad budget. | 15% – 25% of ad spend | Businesses that are ready to scale their paid ads with a large budget. |
| Performance-Based | You pay the agency based on the results they deliver. | Varies; based on cost-per-install (CPI) or revenue share. | Companies with a clear and easy-to-track conversion goal. |
What Should You Expect to Pay in 2025?
Here is a realistic look at what you might get for your money:
- The Startup Special ($5,000 – $10,000/month): This will likely get you a smaller agency or a basic retainer package. The work will focus on ASO and managing one or two ad channels to find your best users.
- The Growth Stage ($10,000 – $25,000+/month): Expect a fuller strategy here. This includes ads on multiple channels, smart creative testing, and deep analytics. The agency acts as a core part of your growth team.
- The Enterprise Level (Custom Pricing): Large companies with big budgets will get custom pricing. This includes a dedicated agency team, deep market research, and a global ad strategy.
At Last, The Hardest Part
Choosing an agency isn’t just about the cost. It’s about finding the right fit. An early-stage startup doesn’t need a massive agency retainer. A large enterprise needs a partner with enough resources to handle its scale.
Here is our advice:
- Know Your Goals: Be clear about what you want to achieve. Is it more downloads, better user engagement, or a higher return on ad spend? Define success first.
- Do Your Homework: Look past the agency’s website. Talk to their clients. See the actual results they have delivered.
- Understand the Price: A good partner will explain exactly what you are paying for. If they can’t justify the cost, that is a red flag.
The right mobile app advertising agency can be a game-changer. It can lift your app from obscurity to the top of the charts. But it is a major investment. You need to enter the deal with your eyes wide open. Now you know what to look for. Make the right call.
