CST does not publish fixed pricing. Instead, the total cost varies based on which modules and solver packages you need. A "base" license might start around $20,000–$40,000 for a single node-locked seat, but prices climb quickly when you add advanced solvers, GPU acceleration, multiphysics capabilities, or network licensing options. Modules like Antenna Magus, Filter Designer 3D, or WASP-NET are sold separately, and a fully loaded floating license for a team can easily exceed six figures.
