FMV stands for fair market value, which is the price of a property, business, or similar asset a person or company may buy based on the calculated value. FMV calculators are often used in the healthcare setting. For example, when a doctor wants to sell their private practice, they would use an FMB calculator to determine what to sell the practice for. The same goes for a hospital. The administrators at a hospital wouldn’t sell the hospital for an amount that is below its worth!
