People who hold a Master of Business Administration degree often have to prepare a biography for personal branding or a job. In doing so, it is common that you come to a point where you must decide whether it is proper to say "a MBA" or "an MBA" in referencing the degree.

Proper Grammar

Conventional wisdom is that you would say "a MBA" because of the common grammatical rule that you use "a" before a consonant and "an" before a vowel. In reality, the rule is a bit more complex, and you actually use "a" before a consonant sound and "an" before a vowel sound. Thus, the proper phrasing in describing your degree is "an MBA," such as "Tom holds an MBA from XYZ University." While "m" is a consonant, it begins with the vowel sound "em."
