The amount of money you spend on training depends on what is required for your new career. Before deciding, research the cost of boot camps, workshops, certifications, equipment, and startup costs. Don't forget to take into account a pay reduction as you factor in your current expenses.  Some companies offer training scholarships, and grants and other funding are available in different industries. Before you spend your own money, find out if there is any financial support available for what you need to learn. Also, assess what level of training or certification is necessary. While some careers may require you to go to graduate school or acquire extended training, you may be able to do on-the-job training with other careers.
