What is an Emergency Fund? As the name implies, an emergency fund is specifically saved for an emergency. This could be due to many unforeseen circumstances, such as medical bills, a car malfunctioning, a pipe burst at home, etc. These can be very expensive bills that need to be paid in a relatively short time. Thus, your emergency fund needs to be (close to) immediately accessible. Another way to say this is that it needs to be liquid.
