"How much does an app cost?" is the "how long is a piece of string?" of the tech industry. The answer can be anything from $10,000 to $10,000,000 depending on what you are building.
But we can do better than that. Here are realistic price ranges based on actual projects in 2026, broken down by type, complexity, and what you get for your money.
Web Application Costs
A web application is software that runs in a browser. Dashboards, portals, SaaS products, e-commerce platforms — these are all web apps.
Simple web app ($15,000 to $30,000):
A few core features, single user role, basic design. Think: a customer portal, an internal tool, or a simple booking system. Timeline: 4 to 8 weeks.Medium web app ($30,000 to $80,000):
Multiple user roles, complex workflows, third-party integrations, custom design. Think: a project management tool, a CRM, or an e-commerce platform. Timeline: 8 to 16 weeks.Complex web app ($80,000 to $250,000+):
Enterprise features, real-time collaboration, advanced security, API platform, white-labeling. Think: a full SaaS platform competing with established players. Timeline: 4 to 8 months.
Mobile App Costs
Mobile apps run on iOS, Android, or both. Cross-platform development (React Native or Flutter) saves significant money compared to building two separate native apps.
Simple mobile app ($20,000 to $40,000):
Core features, single platform or cross-platform, basic design. Content consumption, simple forms, GPS/camera basics. Timeline: 6 to 10 weeks.Medium mobile app ($40,000 to $100,000):
Multiple features, both platforms, custom design, push notifications, payments, offline capability. Timeline: 10 to 20 weeks.Complex mobile app ($100,000 to $300,000+):
Real-time features, chat, video, complex business logic, backend infrastructure. Timeline: 4 to 8 months.
What Makes Apps Expensive
User roles. Every additional user type multiplies complexity. An app with admins, managers, and regular users is significantly more complex than one with just users.
Real-time features. Chat, live updates, collaborative editing. These require WebSocket infrastructure and are genuinely hard to build well.
Integrations. Each API integration takes time to implement, test, and maintain. Some APIs have great documentation. Some do not.
Design polish. Custom illustrations, animations, and micro-interactions take time. A "basic" design and a "premium" design can differ by $10,000 to $20,000 in cost.
Compliance. Healthcare apps need HIPAA compliance. Financial apps need PCI DSS. These add development time for encryption, audit logging, and data handling.
How to Reduce Costs Without Cutting Corners
Start with an MVP. Build the smallest useful version first. Add features based on actual user feedback, not assumptions.
Use cross-platform for mobile. React Native or Flutter delivers 90% of native performance at roughly half the cost of building separate iOS and Android apps.
Choose standard tools. Stripe for payments, NextAuth for authentication, PostgreSQL for your database. Custom solutions cost custom prices.
Invest in design upfront. Every dollar spent on design saves three to five dollars in development rework. It sounds counterintuitive but it is consistently true.
Avoid feature creep. The most expensive apps are not the ones with the most features. They are the ones where features were added mid-development without adjusting timeline or budget.
Budget Honestly
Whatever number you settle on, add 20% for contingency. Not because anyone is trying to overcharge you, but because software development has inherent uncertainty. Requirements evolve, edge cases appear, and third-party APIs do not always work as advertised.
Plan for ongoing costs after launch: hosting, maintenance, updates, and new features. A good rule of thumb is 15 to 20% of the initial development cost per year for maintenance alone.
