Mobile app development cost calculator

Sixteen questions about your features, users, traffic and platform. You get a costed US estimate with hours, timeline and team.

How do you want to start?

Both routes end at the same calculator. One just fills in more of it for you.

What you get at the end

Not a single figure. Four costed views of the same build, each one itemised, and every input still editable afterwards.

A costed breakdown

The total split across ten engineering disciplines, in hours and dollars, so you can see which part of the build is the expensive one.

Hours and a timeline

Engineering hours converted into an elapsed schedule, with the phases overlapped the way they actually run rather than queued end to end.

The team it implies

The roles those hours require and how much of the run each is on for — the difference between a four-person build and a nine-person one.

Twelve months of running it

Infrastructure, maintenance and support after launch. The line most quotes leave off, and the one that outgrows the build cost first.

How the number is built

Not a lookup table. The calculator accumulates engineering hours into ten disciplines, adjusts the ones your scale genuinely affects, then costs the total at a US blended rate.

Product planning

Discovery, requirements, user stories, technical scoping.

UI/UX design

Screens, design system, prototypes, usability and accessibility work.

Mobile development

The app itself — iOS, Android or a shared cross-platform codebase.

Backend development

APIs, business logic, data model, admin and background processing.

Infrastructure engineering

Scaling, caching, queues, storage, media pipelines, observability.

Third-party integrations

Building and hardening each external service connection.

Security & compliance

Controls, hardening, audit logging, review and testing.

QA & testing

Functional, regression, device-matrix, performance and release testing.

DevOps & release

CI/CD, environments, infrastructure as code, monitoring, store releases.

Project management

Planning, coordination, reporting and the cost of keeping it on track.

What another zero on the user count buys

Not a percentage. A cache in front of the hot reads, a queue for anything slower than a request, read replicas, a load test in the release pipeline. Each tier below is the engineering that scale forces — and the calculator prices those hours rather than adding a surcharge to the total.

Small scale

A single well-built backend serves everything.

  • One application service and one managed database
  • Managed authentication and file storage
  • Basic error tracking and uptime monitoring
  • Daily backups, manual restore procedure

Medium scale

Caching, queues and real monitoring become mandatory.

  • Caching layer (Redis or equivalent) in front of hot reads
  • Background job queue for anything slower than a request
  • Read replicas and query-level database tuning
  • Structured logging, metrics and alerting on real SLOs
  • Load testing as part of the release process

High scale

The system is distributed, and it has to be designed that way.

  • Horizontal scaling behind a load balancer with autoscaling policies
  • Service decomposition for the hot paths
  • Partitioned or sharded data model, connection pooling
  • CDN and edge caching for static and media delivery
  • Distributed tracing and per-service dashboards
  • Sustained and spike load testing against production-shaped data

Enterprise scale

Availability targets drive the architecture, not the feature list.

  • Multi-availability-zone deployment, and multi-region where latency demands it
  • Documented and rehearsed disaster recovery with an RPO/RTO target
  • Event-driven microservices with backpressure and circuit breakers
  • Full observability stack — tracing, profiling, anomaly detection
  • Capacity planning, chaos and failover testing
  • Infrastructure as code with automated, auditable environment provisioning

Or start from your app category

Every category loads the features apps of that kind almost always need, so you are editing a sensible list rather than filling in a blank one.

Mobile app development cost — common questions

How much does it cost to develop a mobile app in 2026?

For a US-based team, between about $45,000 for a genuinely small single-platform MVP and $2M+ for a high-scale consumer product with two native apps, real-time infrastructure and a recommendation system. Most funded first releases land between $150,000 and $600,000. The range is wide because "an app" describes a phone icon, not a scope — which is why this site asks sixteen questions instead of one.

Why are your numbers higher than other app cost calculators?

Because this one prices US teams only, and it prices a production build rather than a prototype. Most sub-$100,000 figures online assume an offshore team at $25–$50 per hour, a feature list a third the length, and no budget line for QA, DevOps, security or project management. Those four disciplines are roughly a third of a real build. We show them as separate rows so you can see exactly what you are being quoted for elsewhere.

What is actually included in the estimate?

Product planning, UI/UX design, mobile development, backend development, infrastructure engineering, third-party integrations, security and compliance work, QA, DevOps and project management. Excluded, and stated on every result: cloud hosting, third-party service fees, app store fees, content production, marketing, legal counsel and audit or certification fees. Cloud and vendor costs are estimated separately as a monthly figure.

How does the number of users change the cost?

Not as a percentage. Scale changes what gets built. Below roughly 25,000 monthly active users, one well-built service and a managed database carry the product. Past that you need a caching layer, a job queue, read replicas and real monitoring. Past a few hundred thousand you need horizontal scaling, a CDN, partitioned data and load testing against production-shaped data. Each of those is engineering hours, and the results page lists exactly which ones your answers triggered and why.

Is it cheaper to build for one platform first?

Yes, and it is usually the right call. A single native iOS app is the cheapest route to a real product. Two native codebases cost about 60% more on the client side — though not on the backend, which is the same either way. React Native or Flutter sits in between at around 25% over a single native app and covers both stores, with native work still needed wherever you touch the camera, background location or payment SDKs.

What does an app cost to run once it is built?

Two ongoing costs, and they are separate. Cloud infrastructure runs from about $200 per month for a small app to five figures monthly for a media-heavy product at scale — the calculator estimates yours from your traffic, storage and media answers. Maintenance is 15–25% of build cost per year for bug fixes, OS and SDK updates, security patching and small improvements. Budgeting for the build and not for these two is the most common planning mistake we see.

How long does it take to build a mobile app?

A small single-platform MVP is 2–4 months. A funded consumer product with a custom backend is typically 6–10 months. A two-sided marketplace with two apps, real-time dispatch and payments is 9–14 months. Compressing a schedule by adding people works up to a point and then stops working — the calculator models that, which is why doubling the team does not halve the timeline.

Are the reference apps like Netflix and Uber accurate?

They are accurate as templates and make no claim to be anything else. Each profile describes the shape of that kind of product — the features, the architecture and the scale a US team would plan for in year one. Nobody outside those companies knows their real systems, real infrastructure or real development cost, and this calculator does not pretend to. Every value a template loads is editable in the wizard.

Should I hire freelancers, a small team or an agency?

Freelancers at $40–$100 per hour work when you have a technical founder driving the architecture and accepting the coordination load. A small team at $60–$120 is the common choice from funded MVP through Series A. An agency at $100–$180 buys predictability and the disciplines that are invisible until they are missing. Enterprise delivery at $150–$250+ is justified by regulation, multi-region requirements or systems you do not control. The calculator prices all four.

Do you store the answers I enter?

No. The calculation runs entirely in your browser and nothing is transmitted while you work through it. The only data that ever leaves your device is what you deliberately type into the form at the end, after your estimate has already been shown to you in full. See the privacy policy.

What the numbers look like

Both charts are live output from the calculator on this page, generated at build time — not illustrations drawn to look about right.

Where the budget goes

A typical e-commerce build, split across the disciplines the estimate accumulates. The app itself is the small part — it is the backend and the infrastructure behind it that carry the bill.

What comparable apps cost

The same calculator run over 7 reference builds, cheapest to dearest. The spread between the ends is about 5× — which is why a single average figure for “a mobile app” is useless.
