How many months should you keep?
Three months of essential expenses is the classic floor for someone with a steady paycheck and no one depending on them. Variable income pushes the floor to six months because slow months arrive without warning, and each extra mouth adds time you would need to keep a household running. The tiers land between three and nine months; the goal is a cushion that lets you make decisions from a position of strength, not panic.
Where to keep the money
An emergency fund belongs somewhere safe and boring: a high-yield savings account or money market fund you can reach within a day or two. You are trading some return for certainty, and that is the point. Keep it separate from checking so it is not casually spent, but not locked away where a real emergency turns into a payday loan.

在中国大陆做财务换算时，以下框架值与美国默认值差异很大：
- 个人所得税: 工资薪金基本减除费用为 5,000 元/月（60,000 元/年），综合所得适用 3%–45% 七级超额累进税率（自 2019 年起施行）。
- 社保与公积金: 养老保险单位缴费 16%、个人 8%；住房公积金常见缴存比例为 5%–12%，由各城市确定上下限。
- 价签与增值税: 标价为含税价（一般纳税人增值税率 13%/9%/6%），结账时不额外加税，与美国小票加税习惯不同。
- 数字与单位: 使用公制单位（厘米、米、千克、升），温度为摄氏度；人民币符号 ¥，千分位用逗号、小数用点：12,345.67 元。
- 小费文化: 餐厅不付小费，部分场所收取服务费并已在账单中标明；无需按美式 15%–20% 计算。

常见问题
What counts as an essential expense?
Housing, utilities, groceries, insurance, transportation, and minimum debt payments — the bills that keep a household standing. Dining out, subscriptions, and vacations do not make the list, which is why the target is usually smaller than a full month of spending.
Should I save for emergencies or pay off debt first?
Most planners suggest a small starter fund (about one month of essentials) even while tackling high-interest debt, then building toward the full target once the expensive debt is gone. That way a flat tire does not become new credit card debt.
