A custom web app costs between $2,000 and $15,000 for most small business projects when working with a fixed-price developer like MGT. Enterprise builds from traditional agencies range from $50,000 to $300,000+.
The most common question I get from potential clients is some version of "how much does a web app cost?" The honest answer is: anywhere from $2K to $250K, and the range is that wide for real reasons. The number is determined almost entirely by four factors: complexity, who you hire, how well scope is defined upfront, and whether the work is fixed-price or hourly. Let me break each one down so you can apply it to your specific project.
Custom Web App Cost Breakdown (2026)
| Complexity | Price Range | Timeline | Examples |
|---|---|---|---|
| Simple | $2K–$5K | 2–4 weeks | Landing page, portfolio, basic CRM |
| Medium | $5K–$10K | 4–8 weeks | SaaS MVP, dashboard, e-commerce |
| Complex | $10K–$15K | 8–12 weeks | Multi-tenant platform, marketplace |
These ranges assume a fixed-price solo developer with modern tooling. Traditional agency pricing runs 3x to 5x higher for equivalent scope due to overhead, project management layers, and hourly billing structures.
What Actually Drives the Price
Complexity is the biggest lever. A simple marketing site with a contact form and five pages is a $2K to $5K project. Add user authentication, a database, and a dashboard and you are at $6K to $15K. Add payment processing, subscription management, and an admin panel and you are at $15K to $40K. Add multi-tenant architecture, third-party API integrations, and real-time features and you are at $40K and up. Each feature category roughly doubles the scope because more features mean more data models, more API endpoints, more state management, more error handling, and more test coverage.
Who you hire changes the number dramatically. An offshore agency will quote $8K for a project that a US agency quotes $60K for. A solo developer with the right tooling will often quote $12K for the same project the US agency quoted $60K for, and deliver it in half the time. The difference is not quality. It is overhead. Agencies charge for project management, discovery phases, account management, QA as a separate billing line, and revision rounds. Solo developers charge for software. The comparison page shows exactly how this breaks down across four hiring options.
Scope definition is the hidden cost driver. Vague scope is expensive regardless of who you hire. When the requirements say "users can manage their profile" without specifying what fields, what validation, what privacy controls, or what the edit flow looks like, every ambiguity becomes a change order later. At $150 to $300/hour, a few rounds of scope clarification after development starts can add $5K to $15K to a project that was quoted at $20K.
Typical Price Ranges by Project Type (2026)
These are real ranges based on projects I have built or quoted, not survey data:
- Landing page with CMS: $2K to $5K, 1 to 2 weeks
- Business website with contact forms and blog: $3K to $8K, 2 to 3 weeks
- Web app with user auth and database: $6K to $18K, 3 to 6 weeks
- SaaS MVP with billing: $12K to $30K, 6 to 10 weeks
- Multi-tenant SaaS platform: $25K to $60K, 3 to 5 months
- Enterprise system with integrations: $60K to $250K+, 6 to 18 months
These assume a US-based developer, fixed pricing, and well-defined scope. Add 40% to 60% if you are hiring an agency with PM overhead. Subtract 30% to 50% if scope is tight and the developer has direct domain experience in what you are building.
Why Fixed Pricing Changes Everything
Hourly billing puts the budget risk entirely on the client. If the developer underestimates, you pay more. If requirements are slightly ambiguous, you pay for the clarification time. If the developer is slow on a particular problem, you pay for that too. The client has no ceiling on spend, which makes planning impossible.
Fixed pricing transfers the risk to the developer. If I underestimate, I eat the difference. That creates a strong incentive to scope carefully, build efficiently, and not drag out the work. VIBE CRM went from concept to deployed multi-tenant SaaS in under 60 days at a fixed price. Regal Title shipped in 3 weeks. The full breakdown of fixed vs hourly covers the incentive alignment in detail.
How MGT Pricing Works
MGT projects start at $2K for simple sites and scale up based on scope. The process is: 30-minute discovery call, one-page scope document, fixed price, delivery. No surprise invoices. No change orders for things in the original scope. No hourly billing for maintenance within the warranty period.
The price ranges I use for real engagements are public on the pricing page, and the ROI calculator lets you compare those numbers against a typical agency quote for the same project. Most clients find the comparison uncomfortable in a useful way.
The Fastest Way to Get an Accurate Number
The project estimator at /estimate will give you a real range in about two minutes. It covers the same factors I cover in a discovery call: project type, core features, integrations, and timeline requirements. No email required, no sales pitch, just math. If the range looks right for your budget, the contact page is the next step. Discovery calls are free and typically take 30 minutes.
Frequently Asked Questions
What factors affect web app development cost?
The four biggest factors are project complexity (number of features, integrations, and data models), who you hire (agency vs. freelancer vs. solo developer with modern tooling), how well the scope is defined before work begins, and whether the pricing model is fixed or hourly. A well-scoped project with a fixed-price developer will almost always come in lower than a loosely defined project billed by the hour, because ambiguity under hourly billing turns into expensive change orders.
Is it cheaper to build or buy software?
For generic needs like email, project management, or basic CRM, buying off-the-shelf software is almost always cheaper. SaaS subscriptions run $20 to $200/month and require zero development time. Custom development makes financial sense when your workflow does not fit any existing tool, when you need to own the data and the experience, or when the monthly cost of multiple SaaS subscriptions exceeds what a one-time build would cost over 2 to 3 years. The break-even point for most small businesses is around $300 to $500/month in combined SaaS fees.
How much should a startup spend on a web app?
Most startups should spend between $5,000 and $15,000 on a first version. The goal of a v1 is to validate the core idea with real users, not to build every feature on the roadmap. A $5K to $10K MVP with authentication, one core workflow, and a clean UI is enough to get user feedback and prove demand. Spending $50K+ before you have paying users is the most common financial mistake early-stage founders make. Build the smallest thing that tests your riskiest assumption, then iterate with revenue.
What is the difference between a website and a web app?
A website is primarily informational. It displays content that visitors read: pages, blog posts, images, contact forms. A web app is interactive. Users log in, create data, manage workflows, and perform actions that change the state of the system. A restaurant menu page is a website. An online ordering system where customers build orders, pay, and track delivery is a web app. The development cost difference is significant because web apps require user authentication, database design, API development, state management, and more extensive testing. A typical website costs $2K to $8K. A web app with equivalent visual polish costs $5K to $20K+ depending on the complexity of the interactive features.
