What does a web app cost to build in 2026? Complete price guide

What does it cost to build a web app?

The cost of building a web app varies enormously — from €5,000 for a simple application to €50,000+ for a full SaaS platform. The final price depends on several factors.

Price indication per type of web app

Type of application	Price range	Lead time
Simple web app	€5,000 – €10,000	3-6 weeks
Mid-sized web app	€10,000 – €25,000	6-12 weeks
Complex web app / SaaS	€25,000 – €50,000	12-24 weeks
Enterprise platform	€50,000+	24+ weeks

Factors that determine the price

1. Complexity of the features

A simple CRUD application is considerably cheaper than a platform with real-time data, payment integrations, role-based access and API connections.

2. Design and UX

A standard template-based design is cheaper than a fully bespoke UI/UX design with animations and interactive elements.

3. Third-party integrations

Connections to payment providers (Mollie, Stripe), CRM systems, accounting software or external APIs increase complexity and cost.

4. Scalability and infrastructure

An application that must handle thousands of concurrent users requires a more robust architecture than an internal tool for 10 employees.

How can you save on cost?

Start with an MVP — build the core features first and expand later

Use proven frameworks — React, Next.js and Node.js speed up development

Phase the development — split the project into sprints so you can steer along the way

Choose a European agency — direct communication saves time and prevents misunderstandings
