Emergency Fund Calculator
A safety net is the first rule of a sound plan. Size yours in months of essential expenses, see how much you've already got covered, and find out how long it takes to be fully funded at your saving pace.
Estimates are for illustration and education only — not financial advice. Returns are assumed constant and are not guaranteed.
How big should your emergency fund be?
A common rule is 3–6 months of essential expenses — more if your income is variable or you support others. Here's the target for each, by monthly essentials.
| Monthly essentials | 3 months | 6 months | 9 months | 12 months |
|---|---|---|---|---|
| $2,000 | $6,000 | $12,000 | $18,000 | $24,000 |
| $3,000 | $9,000 | $18,000 | $27,000 | $36,000 |
| $4,000 | $12,000 | $24,000 | $36,000 | $48,000 |
| $5,000 | $15,000 | $30,000 | $45,000 | $60,000 |
| $6,500 | $19,500 | $39,000 | $58,500 | $78,000 |
Count only essentials — housing, food, utilities, insurance, minimum debt payments, transport — not discretionary spending. Figures are illustrative.
How to think about your emergency fund
An emergency fund is money set aside for the unexpected — a job loss, a medical bill, a car that dies at the worst moment. Its job isn't to grow; it's to be there, in cash, the day you need it. This calculator sizes that cushion in months of essential expenses and shows how quickly your current pace fills it.
How many months should you hold?
Three months is a reasonable floor for a stable single income with few dependents. Six months is the common default. Lean toward nine to twelve if your income is irregular, you're self-employed, you're a single earner supporting a family, or you work in a volatile industry. When in doubt, more is safer — but don't let the perfect number stop you from starting.
Count essentials, not your whole budget
Size the fund on what you'd truly have to keep paying if income stopped: rent or mortgage, groceries, utilities, insurance, minimum debt payments, transport. In a real emergency you'd cut streaming subscriptions and dining out — so leaving them out keeps the target realistic and reachable.
Where to keep it
Liquidity beats yield here. A high-yield savings account or money-market fund lets the balance earn a little — which is why this tool includes a modest return — while staying instantly accessible and stable. Don't put your safety net in stocks; the moment you're most likely to need it is often the moment the market is down.
Build it before you invest aggressively
A funded emergency fund is what lets you invest for the long term without panic-selling when life happens. Once it's full, redirect that monthly contribution into our compound interest calculator and let the same habit build real wealth.
How big should your emergency fund be?
The target isn't a round number — it's a multiple of your essential monthly spending. Cover the bills that don't stop if your income does, times the number of months you want as a buffer.
How many months do you need?
There's no universal number. The steadier and more replaceable your income, the smaller your buffer can safely be.
Leaner cushion 3 months
- Stable salaried job in a resilient field
- Dual income, so one loss isn't total
- Few dependents relying on you
- Good insurance and low fixed costs
Bigger cushion 6–12 months
- Variable, freelance or commission income
- Single income supporting a family
- Specialised role that takes longer to replace
- Business owner or your own healthcare risk
Keep it separate and reachable. An emergency fund belongs in a high-yield savings account — earning something, but instantly accessible and walled off from day-to-day spending. It shouldn't be invested in stocks, where a downturn could shrink it exactly when you need it.
Build it before you invest aggressively. A cash buffer is what lets you leave long-term investments untouched during a rough patch, so they can keep compounding. It's the foundation the rest of your plan stands on.
