Emergency Fund Calculator
Your numbers
Two fields. We size the target from what your life actually costs to run — not your whole budget — and show how far along you already are.
Housing, food, utilities, insurance, minimum debt payments — not discretionary spending
Cash you could actually reach this week — 0 is fine
How we calculate this
The target is one multiplication: your essential monthly expenses times a number of months. What makes it useful — or useless — is which expenses you count and which multiple you pick.
Essential means what continues if income stops. Housing, food, utilities, insurance, and minimum debt payments. Not restaurants, not travel, not the subscriptions you'd cancel in week one. People routinely plug in their entire monthly spend and walk away with a target thousands of dollars too high, then feel hopeless about a number they never needed to hit.
The months figure is a convention, not a statistic — and we won't pretend otherwise. Three to six months is standard personal-finance guidance, and a longer runway is conventionally advised when income is irregular. But no authority publishes a correct number, and anyone citing one is dressing up judgment as data. We default to 6 months for a single salaried income, offer 3 when two stable incomes share the risk, and 9 when one variable or self-employed income carries the household. All three are editable, because your job market, health, and dependents matter more than any default.
If you don't tell us a savings rate, we don't invent a timeline. A tool that answers "how long will this take?" with "0 months" because you left a field blank is worse than one that says it needs the number.
What this doesn't model: interest earned on the balance (a high-yield savings account helps, but it isn't the point of this money), inflation over the saving period, and the real question of where to keep it — which should be somewhere boring and instantly reachable, not invested.
Real scenarios
$4,200 of essentials, six months: a $25,200 target and 28 months of work
With $8,500 saved, this household already has 2.0 months of cover — real protection, just not the whole plan. The gap is $16,700, and at $600/month it closes in 28 months. Framed that way it's a finite project rather than a vague inadequacy.
Variable income, starting from zero: $45,000 and exactly 36 months
A self-employed earner with $5,000 of monthly essentials targets 9 months, not 6, because irregular income is exactly the risk this fund exists for. From zero at $1,250/month that's three years. Long — but the first month of expenses saved already removes the worst outcome, and the target is a destination, not an entry fee.
Already funded: the answer is stop
$12,000 against $3,000 of monthly essentials at a 3-month target is 4.0 months of cover — past the goal. The tool says so plainly and tells you the next dollar belongs against high-interest debt or in long-term investing. Cash beyond your target quietly loses purchasing power every year.
