According to research, the average salary of a UX designer in the US is $115,743 per annum. This can go up to $134,395 for experienced designers. When it comes to UI designers, the average salary is $73,040 per annum approximately and for an experienced designer, it is $103,026 per annum. By this, we can say that UX designers are paid more when compared to UI designers because in designing UI designers focus only on one portion of the design when it comes to UX designers they focus on the whole design of interface. My suggestion is to learn both UI/UX design because companies are paying attractive salaries to those having both skills. For that, if you are looking for a course I recommend you to take up Intellipaat UI UX training course where they help you to master both the tools in a single course.
