A treadmill can be as affordable as $140 and as pricey as $2,300. It's important to understand the different price ranges and the features you're likely to get with each.
The cheapest treadmills cost approximately $140 to $200. These treadmills are likely to be manual, meaning there's no motor to move the belt of the machine--the exerciser's stride propels the belt. These machines take more effort to use and are not suitable for jogging or running.
In the low to middle range are treadmills that cost $400 to $600. These models are powered, have about four pre-set exercise programs, and can reach speeds up to 10 MPH. They have a display that shows speed, elapsed time, distance, and heart rate.
In the high to middle range, treadmills cost $800 to $1,400. They typically come with 15 pre-set programs, a fan to cool the user, and a larger running surface (typically 20 by 60 inches).
The most expensive treadmills offer the most feedback information and cost upwards of $2,000. They have six display screens, can reach 12 miles per hour, and inclines up to a 15 percent grade. Some even offer a chest strap for a more accurate heart rate measurement.
