The cost of buying a monkey can vary greatly, depending on several factors. The price could range from less than $1,000 for a common species of monkey, such as a capuchin or a Marmoset, to over $5,000 for a rarer breed of monkey, such as a tamarin or a Patas monkey.
Additionally, it could cost thousands of dollars more to register a monkey as a service animal and keep it in compliance with local regulations. Generally speaking, the cost of owning a monkey is considerably more than the initial purchase price.
