Emergency fund.
In plain English
An emergency fund is money parked somewhere boring and accessible (usually a high-yield savings account) that you only touch when something genuinely bad happens. The standard rule of thumb is 3 to 6 months of essential expenses (rent, food, insurance, utilities, minimum debt payments). Not 3 to 6 months of your full lifestyle.
01Why it matters
It's one of the strongest predictors of whether a setback turns into a crisis. The same job loss is annoying with an emergency fund and devastating without one. It's also what keeps you from putting unexpected expenses on a high-APR credit card.
02The math, step by step
Your essential monthly expenses (rent, utilities, food, insurance, minimum debt) are $2,500. A 3-month emergency fund is $7,500. A 6-month fund is $15,000. Most people start with a $1,000 starter fund, then build from there as they pay off high-interest debt. The number matters less than the habit.
Illustrative example. The amounts here are hypothetical, chosen to show how the math works, not real quoted rates or figures.
03What this is NOT
An emergency fund is for unplanned bad news (job loss, medical bill, car breakdown). 'Savings' usually means money set aside for a planned thing (a down payment, a wedding). They should be in different accounts so you don't accidentally raid the emergency fund for the planned goal.
