The emergency fund, decoded

An emergency fund is plain cash set aside for the surprises that always come: a car repair, a medical bill, a lost week of work. Its whole job is to absorb a shock so the shock does not turn into high-interest debt. The difference between paying from cash and paying with a card is the entire game.

• A small starter buffer, roughly $1,000 to $2,000, stops most surprises from landing on a credit card.
• Three to six months of essential expenses is the common target once the starter buffer is in place.
• Paying a shock from the fund costs nothing extra. Putting it on a card means it compounds, often around 20% to 27% a year.
• Refill the fund after you use it. That is the normal cycle, not a failure.
