The IELTS Exam Usually Costs About $225. Unfortunately, each test center sets its own fee, so there is no one single answer to how much the IELTS costs. However, most IELTS testing centers now charge around $225 to sit for the exam. It was about $210 until early in 2015. While a $225 fee is the normal amount that gets charged, though, some testing centers may be lower or higher.
