What it is
An emergency fund is money saved for unexpected expenses. The U.S. Consumer Financial Protection Bureau points out why it matters: if a credit card or loan pays for the emergency, interest and fees can make it much larger than the original bill.
How big? The CFPB doesn’t give a number of months; it depends on your situation. Look at the unexpected expenses you’ve actually had and what they cost, and set your goal from that. Many personal-finance writers suggest three to six months of expenses. If saving is hard, the easiest starts are managing your cash flow and putting away part of a tax refund. Saving consistently matters more than the size, and if you spend the fund, rebuild it.
How it shows up for me
I learned the value of it by not having one. Now it’s the first line in my budget, before anything I’d call a goal.
