The cost to develop a web app depends on product type, feature scope, complexity, and timeline. Use the calculator above to get a custom estimate, or read the common questions below.
A SaaS MVP typically costs between $4,000 and $15,000 depending on feature complexity. Core features like user authentication, dashboard UI, and Stripe billing form the foundation. Adding subscription billing, usage-based metering, or AI integrations increases the budget. Most solo-founder SaaS products launch with 4–6 key features and expand iteratively after validating market demand.
A marketplace or multi-vendor platform typically costs $5,000–$20,000 to build. The higher range accounts for complex transaction flows, seller dashboards, commission systems, and escrow-style payment handling. Marketplace development requires careful architecture around trust, verification, and dispute resolution — features that don't apply to simpler SaaS tools.
AI features like chatbot integration (OpenAI, Anthropic), AI-powered data analysis, or image generation typically add $3,500–$6,000 per feature module. Custom AI workflows with RAG pipelines, multi-agent chains, or vector databases can push toward $6,000+. These also add ongoing API token costs post-launch, so smart caching and usage limits are essential to keep monthly bills manageable.
Most MVPs take 6–12 weeks to build. A simple internal dashboard with basic CRUD operations can ship in 5–7 weeks. A full SaaS product with auth, billing, and dashboard typically needs 8–10 weeks. Rush timelines (4–6 weeks) are possible but add a 20% budget premium. Flexible timelines can save 10% and allow more polish before launch.
Three factors drive cost the most: feature count (each module adds development hours), complexity level (basic UI vs. custom business logic vs. enterprise-grade specs), and timeline pressure (rush delivery requires premium allocation). The calculator above lets you toggle all three to see exactly how each one shifts your budget and delivery window.
The estimate combines three layers: foundational architecture (server setup, database, auth, routing — included in every build), modular feature toggles (each feature adds its own cost based on engineering hours), and complexity & timeline modifiers (multipliers that adjust the total based on customization depth and delivery speed). This reflects real freelance web developer rates and realistic build timelines — not inflated agency quotes.
