Don't confuse your juror compensation with jury fees. One is money in your pocket, the other is a massive fine for skipping service.
Legal terminology can be confusing. When people search for "jury duty fees," they are usually looking for one of two very different things: the money the court pays them, or the money they have to pay the court if they get in trouble.
The money you receive for serving on a jury is properly called Juror Compensation or a Juror Stipend. It usually consists of a daily attendance fee (e.g., $15/day) plus a travel allowance. It is not considered a "wage" because you are not an employee of the court.
If you ignore a jury summons and fail to show up, the judge can hold you in "Contempt of Court." The penalty for this is often referred to as a fee or a fine. Depending on your state, skipping jury duty can result in fines ranging from $100 to $1,500.
There is a third type of fee. In civil lawsuits (e.g., someone suing a company for a slip-and-fall), the party that requests a jury trial usually has to pay a "Jury Fee" to the court. This fee covers the administrative costs of summoning citizens. This has nothing to do with you as a juror.
Juror compensation is the small stipend you receive for serving. A 'Jury Fee' usually refers to the fines you face for skipping service or the costs lawyers pay to request a jury trial.
