The cost of a treadmill can vary greatly depending on the size, features, and brand. Generally speaking, you can expect to pay anywhere from $400 to $3000 or more for a quality treadmill. If you’re looking for something on the lower end, consider a manual treadmill, which typically cost around $100 to $200. If you want something with more features, such as an electronic display and a variety of programs, you’ll need to pay more. Ultimately, the cost will depend on your specific needs.
