emergency-fund-planner

Skill0 starsChanged 41 days agoMITView on GitHub

Sizes an emergency fund from essential expenses and household risk tier, picks the right account, and builds the funding and replenishment schedule. Use when someone asks "how much should I have in savings", "how big should my emergency fund be", "where should I keep my emergency fund", or "should I save or pay off debt first". Do NOT use for sequencing debt payoff itself - use debt-payoff-planner instead; for planned irregular expenses like car registration or gifts, those are sinking funds - use budget-builder; for the full save-vs-invest ordering - use financial-planner.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Emergency Fund Planner

An emergency fund is not a savings account - it is insurance against being forced into high-interest debt during a crisis. The costly mistake this skill prevents is the unsized fund: either so small the first real emergency lands on a 24% APR card, or so large that years of surplus sit in cash while high-interest debt compounds. Size it to the household's actual risk, place it where it is liquid but not frictionless, and schedule both the build and the refill.

Operating procedure

Step 1: Gather inputs

Label guesses as guesses; refine from statements.

  1. Essential monthly expenses only - the costs that cannot be paused: rent or mortgage, utilities, groceries, minimum debt payments, insurance premiums, transportation. Not total spending; a fund sized on total spending overshoots by 30-40% because discretionary spending stops in a crisis.
  2. Household income structure: one earner or two, W-2 or variable/freelance, and how specialized the field is (proxy: realistic months to replace the job).
  3. Current liquid savings and account type.
  4. Any debt above 7-8% APR (changes the build order in Step 3).
  5. Known risk amplifiers: health conditions, old car or house, dependents.

Step 2: Size the target by risk tier

The base is 3-6 months of essential expenses. Pick the tier, then add one month per significant risk amplifier:

  • Stable two-income household: 3 months - the odds of both incomes stopping at once are low.
  • Single income, stable employment: 4-5 months.
  • Single income, variable or freelance: 6 months minimum - the fund also smooths income gaps between clients.
  • Single income, specialized field with long job-search timelines, or notable health risk: 6-9 months.

State the target as a dollar figure: tier months × essential monthly expenses.

Step 3: Set the build order against debt

  • First milestone: a starter fund of 1 month of essential expenses, before aggressive debt payoff. Without it, every surprise re-creates debt.
  • Then pay down high-interest debt (above 7-8% APR) while holding the starter fund - route sequencing to debt-payoff-planner. No insured savings vehicle outpaces a 20% card.
  • After high-interest debt clears, resume funding to the full tier target.
  • Debt below ~7% APR does not pause the fund build; run both.

Step 4: Place the money

Requirements: liquid within 1-2 business days, principal-safe, and one deliberate step away from daily spending.

  • Default: a high-yield savings account at a federally insured institution, in a separate bank from the checking account. Yield should roughly match inflation; chasing an extra 0.3% is not worth losing FDIC/NCUA insurance or same-week access.
  • Not the stock market, not a CD with penalties - a crisis and a drawdown arrive together often enough to disqualify market exposure.
  • Not the everyday checking account - frictionless access causes quiet erosion from non-emergencies.

Step 5: Schedule the build and define "emergency"

Monthly contribution = (target − current savings) ÷ months to target; set it as an automatic transfer on payday. If the resulting timeline exceeds ~24 months, fund the starter month first, then revisit the budget (budget-builder) rather than accepting a 4-year build.

An emergency is an unplanned, necessary expense: job loss, medical event, major car repair, emergency home repair. It is not a vacation, a sale, or a predictable irregular cost - car registration, holiday gifts, and annual premiums belong in sinking funds (budget-builder), which exist precisely to protect this fund.

Step 6: Replenishment protocol

After any withdrawal, replenishment becomes the top priority above all discretionary savings - treat it as a debt owed to future stability. Restart the automatic transfer at the fastest sustainable rate and pause extra (not minimum) debt payments until the starter month is restored.

Worked example

Single freelance designer, essential expenses $3,400/mo (rent $1,700, utilities $160, groceries $450, insurance $390, debt minimums $340, transport $360). Tier: single variable income → 6 months minimum; add one month for a 12-year-old car → 7 months = $23,800. Current savings $2,000 in checking; card debt at 21%.

Plan: move the $2,000 to a new HYSA today; build the starter month ($3,400 − $2,000 = $1,400 → $700/mo for 2 months); then throw surplus at the 21% card via debt-payoff-planner while holding $3,400; after the card clears, $850/mo automatic transfer reaches $23,800 in ~24 months. Withdrawal rule written on the account: "job gap, medical, car, home - nothing else."

Deliverable

Produce a one-page fund plan containing: essential-expense tally by category, the tier chosen with its justification, the dollar target, the account placement, the monthly automatic transfer amount with milestone dates (starter month by ___, full target by ___), the written emergency definition, and the replenishment rule.

Do NOT

  • Do not size the fund on total spending; essentials only.
  • Do not fully fund 6 months while a 20%+ APR balance compounds - starter month, then debt, then full fund.
  • Do not put the fund in equities or penalty CDs; liquidity failure at the moment of need is the one unacceptable outcome.
  • Do not co-mingle it with checking or with sinking funds; each leak looks harmless and empties the fund.
  • Do not treat a withdrawal as failure - that is the fund working; the failure is not refilling it.

Quality bar

  • The target cites a tier and shows the multiplication (months × essential expenses).
  • Risk amplifiers the user mentioned are reflected in the tier, not ignored.
  • The build order accounts for any debt above 7-8% APR.
  • The plan names an account type, a transfer amount, and two dated milestones.
  • The emergency definition and replenishment rule appear verbatim in the deliverable.

Escalation

This is general financial education, not individualized financial advice. For very high fixed expenses, significant health exposure, or income that swings widely month to month, recommend a certified financial planner to model fund size within the whole plan; route the broader ordering of priorities to financial-planner.
