In financial terms, 10 figures refers to an amount consisting of 10 digits, which can be used to describe a persons net worth or income. Specifically, a 10-figure number ranges from $1,000,000,000 to $9,999,999,999, which is more commonly known as a billion dollars or a thousand million dollars. Earning a 10-figure salary means that a person earns at least $1,000,000,000 (one billion) per year. It is an extremely high amount of money that few people or businesses achieve, and individuals who earn 10 figures are considered billionaires.
