Quick answer: A custom mobile app typically costs between $15,000 and $250,000+ in 2026, depending on complexity. A simple app with basic features (login, a few screens, no backend complexity) runs $15,000–$40,000. A mid-complexity app with user accounts, payments, and API integrations lands between $40,000–$100,000. A complex app — think on-demand marketplaces, AI features, or custom CRM integration — starts around $100,000 and can climb past $250,000. Timeline follows a similar curve: 6–20 weeks for simple builds, 3–6 months for mid-complexity, and 6–12+ months for complex platforms.

Key takeaways

Simple apps ($15,000–$40,000) usually ship in 6–12 weeks; complex apps ($100,000+) can take 6–12 months or longer.
Ongoing maintenance typically costs 15–20% of the original build cost per year, covering OS updates, bug fixes, and server costs.
Building an MVP first — rather than a full-featured app — can cut initial costs by 40–60% while still testing your idea with real users.
The three biggest cost drivers are number of screens, backend/database complexity, and third-party integrations (payments, maps, AI, CRM systems).

Step 1: Figure Out Which Complexity Tier Your App Falls Into

Before you get a quote from anyone, you need an honest read on how complicated your app actually is. Most app costs break down into three tiers, and misjudging which one you're in is the number one reason budgets go sideways.

Here's how the tiers generally break down:

Complexity	Typical Cost Range	Typical Timeline	Example Features
Simple	$15,000–$40,000	6–12 weeks	Login, profile, a handful of static or simple screens, no complex backend
Mid-complexity	$40,000–$100,000	3–6 months	User accounts, push notifications, payments, third-party API integrations
Complex	$100,000–$250,000+	6–12+ months	Real-time features, AI/ML components, marketplace or on-demand functionality, custom CRM or ERP integration

Do this step now:

List every core feature you can't launch without.
Separate "must-have" features from "nice-to-have" ones.
Note whether you need real-time data (chat, live tracking, live inventory) — this alone can bump you a full tier.
Check if you'll need to integrate with existing systems like Salesforce, QuickBooks, or a custom CRM.

If you're building on top of an existing CRM or automating workflows between systems, that integration work often gets underestimated. A business automation consultant or Salesforce specialist can tell you early whether your integration is a small task or a project of its own.

Step 2: Understand What's Actually Driving Your Number

The complexity tier gives you a range, but four specific factors decide where you land within it. Understanding these helps you spot a lowball quote or an inflated one.

Number and type of screens. Each unique screen with custom logic (not just a copy-pasted layout) adds design and development hours. A 10-screen app and a 40-screen app are not close in price.
Backend and database work. Apps that store and sync user data, handle multiple user roles, or need an admin dashboard require significant backend engineering — often 40–50% of total project cost.
Third-party integrations. Payment processors (Stripe, PayPal), mapping (Google Maps), authentication (Auth0, Firebase), and AI features (chatbots, recommendation engines) each add both cost and ongoing maintenance.
Platform choice. Building for iOS and Android separately (native development) costs more than a single cross-platform codebase, but native apps often perform better for graphics-heavy or hardware-dependent apps.

Don't skip this: Get a written breakdown of hours by feature, not just a single lump-sum quote. If a developer can't tell you which features are driving the biggest chunk of the cost, that's a sign the estimate wasn't built from a real technical scope — it was a guess.

Step 3: Decide Between an MVP and a Full-Featured Launch

Building a minimum viable product (MVP) — a stripped-down version with only your core features — instead of a full app can cut your upfront cost by 40–60% and get you to market months sooner. That matters because the biggest risk in app development isn't the build cost — it's spending $150,000 on a full-featured app before you know if anyone wants it.

An MVP typically includes:

The one or two features that solve your users' main problem.
Basic account creation and login.
Just enough design to look credible, not a fully polished brand experience.
No advanced integrations unless they're central to the core function.

Everything else — advanced analytics, loyalty programs, multi-language support, deep AI personalization — gets added in phase two, funded by what you learn from real users in phase one.

We walk through this decision in more detail in MVP vs Full App Launch: Choosing Your Starting Point. If you're working with an MVP development company, ask specifically how they scope phase two so you're not rebuilding core architecture six months in.

Step 4: Budget for What Happens After Launch

Your app costs money every month after it ships, and skipping this step is how businesses run out of runway six months post-launch. Plan for ongoing maintenance at roughly 15–20% of your original development cost per year — a common industry rule of thumb, though your actual number depends on how many integrations and platforms you're supporting.

That maintenance budget typically covers:

OS updates. Apple and Google both push annual operating system updates that can break existing app functionality if you don't adjust for them.
Server and hosting costs. These scale with your user base — a 500-user app and a 50,000-user app have very different backend bills.
Bug fixes and small feature tweaks. Even a well-built app surfaces issues once real users start clicking around in ways you didn't anticipate.
Third-party API changes. Payment processors, mapping services, and AI providers update their APIs regularly, and your app needs to keep pace.
App store fees. Apple and Google both charge developer program fees, and Apple's App Store and Google Play both take a commission on in-app purchases — check current rates directly with Apple and Google since these have changed over time.

Step 5: Match Your Project to the Right Kind of Developer

Not every development team is built for every project size, and picking the wrong fit costs you more than a bad price does. A freelancer might be perfect for a simple app with a tight budget; the same freelancer taking on a complex, multi-integration platform can leave you stuck mid-build.

Freelancers work well for simple apps and MVPs with clear, narrow scope. Expect lower hourly rates but more responsibility on your end for project management.
Boutique agencies (like most custom app shops) fit mid-complexity projects well — you get a small dedicated team, direct communication, and someone accountable for the whole build.
Large development firms make sense for complex, enterprise-scale apps where you need bench depth across multiple specialties at once — AI engineers, backend architects, QA teams — working in parallel.

If your project involves AI integration services — a chatbot, a recommendation engine, predictive features — ask any team you're evaluating for specific examples of AI features they've shipped, not just AI they've experimented with. AI consulting and app development are related but distinct skill sets, and a team strong in one isn't automatically strong in the other.

Step 6: Build Your Realistic Budget Checklist

Before you request quotes, pull together the following. A team that can give you a fast, accurate estimate needs this information up front — and a team that doesn't ask for it may be estimating blind.

Confirm your complexity tier using the feature list from Step 1.
Document every third-party integration you'll need (payments, CRM, maps, AI).
Decide iOS, Android, or both — and whether native or cross-platform makes sense.
Set a maintenance budget at 15–20% of build cost, not an afterthought line item.
Choose MVP or full launch based on how validated your idea already is.
Get itemized quotes from at least two teams so you can compare scope, not just price.
Ask each team for a sample technical scope document, not just a proposal PDF.

What to Do Next

Once you have your complexity tier, feature list, and integration needs mapped out, you're ready for real conversations with development teams instead of guessing games with round numbers. If your project touches an existing Salesforce instance or a custom CRM, loop in a Salesforce consulting specialist before finalizing your app scope — integration surprises discovered mid-build are the most common cause of budget overruns.
