Startup cost: $0 - $100

The low-end estimate assumes you start with no upfront costs, using free survey platforms like Swagbucks, Survey Junkie, or InboxDollars, which require only an internet connection and a device you already own. The high-end estimate includes optional expenses such as a dedicated budget for a faster internet connection, a basic ergonomic setup (chair and desk), and possibly a subscription to a premium survey aggregator service to access higher-paying surveys. Most people find this side hustle to be low-cost, but costs can increase if you choose to invest in comfort and efficiency.
