How it works
Coverage divides your liquid emergency savings by essential monthly expenses — not total spending. The distinction matters: an emergency budget strips dining out, subscriptions, and discretionary travel down to what must be paid no matter what.
The plan section computes how many months of contributions close the gap to your selected target. Keep the fund in a high-yield savings account or money-market fund: accessible instantly, principal stable, earning meaningful yield.
Formula used
Essential expenses— survival-mode monthly outflowContribution plan— gap ÷ monthly contribution = months to finishWhere to keep it— high-yield savings / money market, separate from checking
Example calculation
With $3,200 in essentials and $4,500 saved, coverage stands at about $1. A six-month target sets the bar at $19,200, leaving a $14,700 gap. Contributing $300 monthly closes it in around about 4 yrs 1 mo — after which that same $300 can flow to investments or debt payoff.
Assumptions & limitations
- Essentials exclude discretionary spending by design.
- The fund earns no modeled interest — reality adds a little.
- Insurance, severance, and other safety nets reduce the months you personally need.
- Households with dependents or single incomes benefit from the higher end of ranges.

Frequently asked questions
How much should I have in an emergency fund?
Three to six months of essential expenses suits most households; variable-income earners, single breadwinners, and specialized careers justify nine to twelve. Start with a $1,000 starter buffer while paying off high-rate debt.
Where should I keep my emergency fund?
High-yield savings accounts or money-market funds: FDIC-insured (or equivalent), instantly accessible, and currently paying meaningful yield. Avoid investing it in stocks — emergencies do not wait for recoveries.
Should I invest instead of keeping cash idle?
Keep the emergency tier in cash regardless. Investments can drop 30%+ exactly when layoffs happen. After funding the buffer fully, additional savings become investment candidates.
What counts as an emergency?
Job loss, medical bills, urgent home or car repairs, family crises. A vacation sale, new phone release, or holiday shopping does not qualify — those belong in sinking funds.
