Before thinking about investing, paying down debt, or any other bigger financial decision, there's a prior step that nearly every personal finance expert agrees should come first: having an emergency fund. It's probably the least glamorous but most important foundation of any personal financial plan.
What an emergency fund is and what it's for
An emergency fund is a sum of money set aside exclusively for unexpected events that require immediate liquidity: losing a job, a major breakdown, an uncovered medical expense, an urgent home repair. Its purpose isn't to generate returns, but to prevent an unexpected event from forcing you into debt on unfavorable terms (revolving credit cards, fast loans with high APRs) or into selling off an asset at a bad time.
How much you should have saved
The most common benchmark among financial planners is to cover 3 to 6 months of fixed expenses, not income. That difference matters: what counts is how much you need to live on, not how much you earn. Within that range, some factors that justify leaning toward 6 months (or even more) include:
- Irregular income or self-employed work with variable billing.
- Being the sole breadwinner in the household.
- Working in a sector with high turnover or job instability.
- Not having other backup sources (family, other easily liquidated assets).
If your income is very stable (civil servant status, a well-established permanent contract in a stable sector) and you have other safety nets, it may be reasonable to lean toward the lower end of the range.
How to calculate your monthly fixed expenses
The first practical step is to add up your essential monthly expenses: housing (rent or mortgage), utilities, food, insurance, transportation, and debts with mandatory payments. Don't include discretionary spending (leisure, subscriptions you could drop) in this calculation, since the fund's goal is to cover the essentials, not to maintain your full standard of living indefinitely.
Where to keep your emergency fund
The most important criterion for choosing where to keep this money isn't the return, it's immediate availability without penalty. That, by definition, rules out products with a mandatory holding period, early-withdrawal penalties, or whose value could drop right when you need the money. The most suitable options tend to be high-yield savings accounts or very short-term deposits with no lock-in period, even if their return is modest compared with other investment alternatives.
Why it isn't worth investing your emergency fund in stocks
It's tempting to think that, if that money is going to sit "idle" for a long time, you could invest it for a better return. The problem is that an emergency fund, by definition, might be needed at any moment, including right during a market downturn (an economic crisis that costs you your job often coincides precisely with falling markets). Investing your emergency fund in volatile assets defeats its main purpose: being available at the worst possible moment without losses.
Once the fund is covered, start building wealth
With your emergency fund already covered, the natural next step is to start putting your extra savings toward longer-term goals, where compound interest can genuinely work in your favor over time.
