How many months of expenses should I save if I'm single versus dual-income?

A single earner generally needs a larger cushion — often 6 months of essential expenses — because there's no second paycheck to lean on if you lose your job. A dual-income household can sometimes target 3–4 months, since the odds of both partners losing income at once are lower and one salary can cover essentials while the other job is replaced. Adjust for stability: commission, contract, or single-employer-town situations push the number up; two stable W-2 salaries and strong skills pull it down. Count only essentials — rent or mortgage, utilities, food, insurance, minimum debt payments, transportation — not discretionary spending.
