How much does it cost to build a web application in 2026?

A marketing site with a CMS runs roughly $2,000 to $8,000, a custom web application $8,000 to $40,000, and complex platforms beyond that. Cost tracks complexity: user roles, payments, integrations and AI features move the number more than page count ever does.
