No. 02 — Save
Emergency fund
"Three to six months of expenses" is the standard advice and it is nearly useless, because it never says whose expenses or whose job. The number depends on two things: what you'd actually spend if the income stopped, and how likely the income is to stop.
Size it from essential expenses, not from spending
Start with the wrong number and every month of buffer costs you 40% more than it should. In an actual layoff you do not keep spending what you spend now. Restaurants, travel, the gym, subscriptions, the extra debt payments — those stop the week the income does.
Count only what you cannot switch off inside 30 days: rent or mortgage, utilities, groceries, insurance premiums, transportation to interviews, childcare, and minimum debt payments. A household spending $5,600 a month in normal times often has essentials nearer $3,800. Six months of the first is $33,600; six months of the second is $22,800. That $10,800 difference is roughly a year of saving you don't have to do — and a year sooner that the money can start doing something better. Pull the essentials figure from your budget rather than estimating it; estimates run low.
Then adjust for how you earn
The buffer exists to cover a gap between paychecks, so its size follows the shape of your income risk, not your age or your net worth.
| Household | Target | Why |
|---|---|---|
| Dual income, both salaried and stable, different employers | 3 months | Two independent incomes rarely fail at once; one salary covers most essentials |
| Dual income, same employer or same industry | 6 months | The risks are correlated — one bad quarter takes both paychecks |
| Single income, salaried, stable sector | 6 months | No second income to absorb the gap; median white-collar job searches run months, not weeks |
| Commission, freelance, or contract income | 9 months | Size it against your worst quarter, not your average one |
| Single parent, one income | 9 months | Essentials are inelastic and the job search has a childcare constraint attached |
| Recent hire in a volatile sector (early-stage startup, cyclical trades) | 9–12 months | Last in, first out — and severance is thin without tenure |
Two adjustments on top: add a month if you carry a high deductible on health or auto insurance, and add one if you own rather than rent, because roofs and water heaters do not wait for a good month.
Where to keep it
| Where | Yield (as of 2026) | Access | Principal can move? |
|---|---|---|---|
| High-yield savings account | Roughly 3.5–4.5% | Same day to 2 business days | No — FDIC insured to the limit |
| Government money market fund | Roughly 3.5–4.5% | 1–2 business days to settle and transfer | Essentially no, but not FDIC insured |
| Treasury bills (4–13 week, laddered) | Tracks short-term rates, similar range | At maturity, or sell at market same day | Yes, if sold before maturity |
| I bonds | Inflation-linked, resets twice a year | Locked 12 months; 3-month interest penalty before year 5 | No |
| Checking account | Near 0% | Instant | No |
Yields are ranges typical of the 2026 rate environment and move with short-term rates; check the current posted rate before assuming any of them. Insurance limits and I bond purchase caps are set by the issuer — verify the current figures directly.
Be decisive about this: a high-yield savings account is right for almost everyone, and the marginal gain from the alternatives is not worth the friction. On a $25,000 fund, the spread between a good online savings account and a T-bill ladder is maybe $100 a year. The spread between a good online savings account and the big-bank checking account most people actually use is closer to $1,000 a year, which is where your attention belongs.
Two things that are simply wrong. The stock market is wrong at any size — job losses cluster with market declines, so the one scenario that forces you to sell is the one where you're down 30%. An emergency fund is insurance; it is not supposed to earn a return, and moving it to index funds converts insurance into a bet. A CD is wrong unless laddered, because a single 12-month CD locks the money for exactly the period you might need it; a rolling ladder with a rung maturing monthly fixes that but adds bookkeeping most people abandon by month four. I bonds are a reasonable home for the back half of a large fund once the first three months sit in cash, given the 12-month lockup.
The sequence, and why it isn't arbitrary
Order of operations: a $1,000 starter fund, then high-interest debt, then the full fund, then investing.
Step two looks wrong on a spreadsheet and step one explains why. Paying off a 24% credit card is a guaranteed 24% return; leaving that money in a 4% savings account is a 20-point loss every year you do it. On a $6,000 balance that is about $1,200 a year burned to hold cash. Pure math says put every dollar at the card.
Pure math also assumes the emergency never happens. It does. A household with a zero buffer and a dead alternator has exactly one funding source — the same card — so the balance goes back up, the payoff date slides, and after the third round most people quit. The $1,000 starter is not an investment decision; it is what keeps the debt plan from silently refinancing itself. Once the high-interest balances are gone (the payoff method is its own subject — see get out of debt), finish the full fund, then start investing in earnest.
One exception worth taking: capture a full employer 401(k) match throughout. An instant 50–100% match beats 24% interest, and it is the only thing that does.
Building it fast, and where to physically put it
Treat this as a sprint, not a lifestyle. A temporary spike in your savings rate — three or four months at an uncomfortable level, funded by pausing discretionary categories, a tax refund, a bonus, or a stretch of extra income — finishes the job faster and hurts less than a two-year grind at $150 a month. The temporary plays in frugal living are built for exactly this. Set the target and the date in the savings goal calculator so the transfer is a fixed number rather than "whatever's left".
Then put it at a different bank from your checking account, with no debit card and no linked bill pay. This is deliberate friction. A transfer that takes a day is a transfer you can cancel in the morning, and nearly every non-emergency purchase dies overnight. Name the account something specific — "Job loss / medical / car" — because an account named "Savings" will eventually fund a vacation. Refill it immediately after any withdrawal, and re-check the size after every move, baby, or job change. The fund is the reason the rest of the plan in saving a million dollars never has to be interrupted.
