The conventional wisdom on emergency funds is one should have 3-6 months of fixed costs set aside for a rainy day. The figure is typically cited without context. For example, compare loss of income due to traumatic injury versus an unpaid bereavement leave. Both are equally horrible but each has a different effect on cash flow. Accordingly, how do we ground the emergency fund debate in a more real life scenario?
Assume the best case scenario. Assume a person has back-stopped an emergency situation with short-term disability insurance and long term disability insurance (the different between the two insurance policies is that short-term insurance typically pays out for a shorter period of time and, as such, the insurance premiums tend to be lower).
