You signed the development quote, ran the numbers, and six months in you discover the app costs quite a bit more than what you signed. The hidden costs of building an app —developer accounts, cloud infrastructure, SDK licenses, real-device testing, launch marketing and store commissions— add up to between USD 3,000 and 15,000 in the first year for a typical app, and they don't appear in most development quotes. Most of them aren't avoidable, but they are 100% predictable: the problem isn't that they exist, it's that nobody showed them to you before you signed. Here's the full list, with numbers.
This article is the third leg of our cost series: the first covers how much it costs to build an app (the project itself) and the second how much it costs to maintain it (the monthly cost of evolution). Here we talk about everything else: the operating expenses that exist even if you don't touch a single line of code.
The full table: what hidden costs add up to in year one
| Item | First-year cost | Avoidable? |
|---|---|---|
| Apple Developer account | USD 99/year | No (if you publish on iOS) |
| Google Play account | USD 25 (one time) | No |
| Cloud infrastructure (small → mid app) | USD 600-4,800 | No, but optimizable |
| Third-party services (push, mail, analytics, crashes) | USD 0-1,200 | Partially |
| Commercial SDK licenses | USD 0-3,000 | Depends on the case |
| Certificates and code signing | USD 0-400 | Mostly yes |
| Real-device testing | USD 500-2,000 | Not worth avoiding |
| ASO and minimum launch marketing | USD 1,000-4,000 | Avoidable, but it costs you users |
| Typical first-year total | USD 3,000-15,000 | — |
On top of this comes the store commission on digital sales (15-30%), which isn't a fixed cost but a percentage of your in-app revenue. We cover it in detail below.
Cost by cost: where each number comes from
Developer accounts: the entry toll
- Apple Developer Program: USD 99/year, renewable. If you stop paying, the app comes off the App Store. The Enterprise version (internal distribution without a store) costs USD 299/year.
- Google Play Console: USD 25, one-time payment.
A detail that matters: the accounts should be in your name, not the provider's. If the relationship ends badly and the account is theirs, your app and its reviews are held hostage.
Cloud infrastructure: the cost that scales with your success
The server running your backend, the database, photo storage and data transfer are all billed by usage. Realistic 2026 ranges:
- Small app (up to 1,000 active users): USD 50-150/month.
- Mid-size app (10,000-50,000 users): USD 200-800/month.
- Usage spikes (a giveaway, a campaign, a press hit): can double that month's bill.
It's not avoidable, but it is optimizable: an architecture sized well from development onward can cost half what one thrown together without thinking about the bill does. Always ask for the estimate broken down by user tiers.
Third-party services and SDKs
Almost every modern app leans on external services that start free and charge as you scale:
- Push notifications: free with Firebase; advanced engagement solutions, USD 100-500/month.
- Transactional emails: free up to ~3,000/month; after that USD 15-100/month.
- Error monitoring and analytics: generous free tiers; paid plans USD 30-150/month.
- Commercial SDKs: maps beyond Google Maps' free credit, search engines like Algolia, video, digital signatures. This is where USD 100-250/month nobody mentioned can show up.
The question for your provider: "which third-party services does the app use and how much do they cost at 1,000, 10,000 and 50,000 users?". The answer should exist before a line of code is written.
Real-device testing
The emulator doesn't catch everything: the keyboard that covers a button on a mid-range Samsung, the notch that eats a title on an old iPhone. Testing across a reasonable matrix of devices —your own or via cloud device farms (USD 100-250/month for the duration of intensive testing)— costs USD 500-2,000 in the first year. It's one of the most tempting costs to cut and one of the most expensive to have cut: the bugs that slip through get charged back in 1-star reviews.
ASO and launch: the app nobody finds doesn't exist
Publishing isn't launching. A serious minimum includes:
- An optimized store listing (keywords, screenshots, video): USD 500-1,500 if a specialist handles it.
- An initial install campaign to kick-start the algorithm: USD 500-2,500.
It's the only genuinely avoidable line on the list — but avoiding it has its own cost: an app with no initial downloads doesn't rank, and an app that doesn't rank doesn't get downloads. If your model depends on volume, also look at how to monetize an app to size how many users you need.

The store commission: the silent partner
If you sell digital goods or services inside the app (subscriptions, content, premium features), Apple and Google keep:
- 30% standard, dropping to 15% if you bill under USD 1 million/year (Apple's Small Business Program; Google Play's reduced tier).
- Doesn't apply to physical goods or services consumed outside the app: the ecommerce that charges through its own payment gateway pays no store commission — one of the reasons behind the model we analyze in your own delivery app with no commissions.
The classic mistake: building the pricing model without deducting the commission, then discovering the real margin is 15-30 points lower than planned.
Certificates, domains and other small items
Domain (USD 10-40/year), SSL certificates (free with Let's Encrypt, save for corporate requirements), code signing for enterprise distribution. Small individually; together, USD 100-400/year that's still worth writing down.
Which are avoidable and which aren't
Not avoidable: developer accounts, cloud infrastructure, store commission on digital sales. They're the cost of existing in the mobile ecosystem.
Optimizable: third-party services (by choosing free tiers well), infrastructure (with good architecture), commercial SDKs (by evaluating open-source alternatives before signing licenses).
Avoidable with consequences: real-device testing and ASO. You can choose not to pay them; you'll pay for the result.
When these costs should NOT worry you
Honesty first: if your app is an internal project for 50 employees, half this list doesn't apply to you — there's no ASO, no store commission (enterprise distribution goes through another channel, we cover it in internal apps for employees), and the infrastructure is stable and predictable. And if you're validating an MVP with 200 users, cloud costs will be in the tens of dollars, not the hundreds: don't let this list paralyze you. The moment to take it seriously is when you plan to scale.
How to demand a quote with no surprises
Before signing with any provider, ask in writing for:
- A first-year operating cost projection, separate from the development cost, with user tiers made explicit.
- A list of third-party services the app will use, with their pricing models.
- Ownership of the developer and cloud accounts in your name.
- What the launch includes: is publishing to the stores in the price? The optimized listing?
If the answer to any of these is vague, you already know where the surprises will show up.
At Deepyze every proposal includes the first-year operating cost projection alongside the development price — fixed, with no line items that appear later. Tell us about your project and within 24 hours you'll have the full picture: development, operation and launch, with a team for mobile apps and custom software in your time zone.
Frequently asked questions
How much do the hidden costs of an app add up to in the first year?+
Between USD 3,000 and 15,000 in the first year for a typical app, not counting development or ongoing maintenance. It covers developer accounts, cloud infrastructure, third-party services, real-device testing and a minimum of launch marketing.
How much do Apple and Google developer accounts cost?+
Apple charges USD 99 per year for the Apple Developer Program (USD 299 for the Enterprise version). Google Play charges USD 25 one time. Both are mandatory to publish, and Apple's renews: if you stop paying, your app comes off the store.
How much do the stores charge on each in-app sale?+
The standard commission is 30% for Apple and Google, dropping to 15% if you bill under USD 1 million a year (Apple's Small Business Program and Google Play's reduced tier). It applies to digital goods purchases, not physical products or services consumed outside the app.
Why do server costs grow with users?+
Because most cloud services charge by usage: storage, data transfer, notifications and processing all scale with activity. An app might cost USD 50/month in infrastructure with 500 users and USD 800/month with 50,000.
How do I avoid surprise costs after signing?+
Demand that the proposal include a first-year operating cost projection: accounts, infrastructure estimated by user tiers, third-party service licenses and store commissions. If the provider can't put one together, that's a red flag about their real experience.
