The cost of designing a website will vary depending on factors like whether you are doing it yourself or hiring someone else to do it for you, whether you are self-hosting or using a hosted website builder, whether you are purchasing any premium tools and plugins, and so on. Designing your own website is the cheapest option. When doing everything for yourself, you can expect to spend anywhere between $100 and about $2,000. If you are hiring a professional designer or agency to do it for you, the costs will go higher. You can expect to pay between $10,000 and $30,000 depending on the complexity of your website.  For big websites with advanced functionalities, the costs can sometimes exceed the $100,000 mark.
