There are 2 approaches of Magento website expenses. The first one is related to develop a website and the second one is the cost of maintenance.
- The cost of developing Magento website start from $900 to $60,000. Magento doesnt allow you to add easily plugins and custom theme. There are few theme that have some good editorials tools but overall you will probably need a programmer to customise your website. As an example, the cost of developing Little Live Pets & Zanussi websites for DMS was $4,200.
- The cost of maintenance is mixed on Magento. Cost is lower than Drupal but way higher than WordPress. You can estimate from $3,000 to $30,000 to maintain and keep developing a good Magento website. A new landing page like Unox can be easily $500 for the content, layout and coding.
