A variety of elements determines a UX design project's cost. The factors include, for example, the project's scope and size, type (beginning from scratch, reworking current design), platforms (mobile, web, TV, kiosk), the technology used, and design services included (user research, interviews, testing), as well as the timeframe for delivery.
Without comprehensive knowledge about the project's requirements and scope, it isn't easy to generate an estimate upfront. UX design projects generally last between three and six months.
When it comes to UX design, everything from scope to complexity to platforms to money to client feedback impacts how long it takes to complete the project. An average UX design project could last anywhere from 2-3 months to 6 months for a small-medium-sized project. Larger projects may take up to a year to complete, depending on their size and complexity.
