In general, lead singers in major opera companies can earn hundreds of thousands of dollars per year. For example, in the United States, the Metropolitan Opera pays its lead singers an average of $300,000 per year. However, lead singers in smaller companies or less popular operas may only earn a few thousand dollars per year.
In addition to their base salary, opera singers may also receive additional compensation for performances that are streamed or broadcast online, appearances on radio or television, and recordings. Some opera singers also supplement their income by teaching music or giving private voice lessons.
Overall, the potential earnings of an opera singer can vary widely, but with talent, dedication, and a bit of luck, it is possible to have a successful career in the industry.
