It’s not a matter of if an emergency will happen, but when. Murphy’s law (if something can go wrong, it will) will strike. Instead of taking on additional debt to be able to swing these expected, yet unexpected events, an emergency fund can help see you through these stresses. You can build this “buffer” from your budget by either reducing your discretionary expenses or increasing your income.
An emergency fund is money you have set aside in a savings account to help you cover those emergency situations that happen in life.
