¿De qué tamaño debe ser tu fondo de emergencia?

La clásica regla de "3 a 6 meses" es un punto de partida — tu cifra real depende de tus gastos y de cuán estable sea tu ingreso. Aquí está la tuya, y lo cerca que estás.

An emergency fund is cash held in an easily accessible, low-risk account (like a savings account) specifically to cover unplanned expenses or a sudden loss of income — without having to sell investments at a bad time or go into debt. The commonly cited guideline is 3 to 6 months of essential expenses, though the right number depends heavily on your circumstances.

How the target is calculated

The baseline math is straightforward: (monthly essential expenses) × (months of coverage). Essential expenses means housing, utilities, food, insurance, minimum debt payments, and other non-discretionary costs — not your full current spending, which may include savings and discretionary items you could cut in a crunch.

Why 3-6 months isn't one-size-fits-all

Dual-income households with stable employment (e.g., government jobs) can often lean toward 3 months, since a lost income is only a partial income shock and typically easier to replace. Single-income households, commission-based or gig income, self-employed people, and those in volatile industries are frequently advised toward 6-12 months, because both the probability and the duration of an income gap are higher.

Why it matters

Without a cash buffer, an unexpected expense (medical bill, car repair, job loss) often gets funded with high-interest credit card debt or by selling investments during a downturn — locking in losses at the worst possible time. An adequately sized fund is also what makes every other calculator on this site (runway, severance planning, sabbaticals) actually usable, since it's the floor beneath any income gap.

Common pitfalls

Keeping the fund in a checking account earning near-zero interest wastes purchasing power to inflation — a high-yield savings account is the standard recommendation. Equally common: counting money you'd actually need to liquidate a retirement account (with tax penalties) as part of the "emergency" fund, which defeats its purpose of being instantly accessible without cost.

Sueldo estable → 3. Ingreso variable/freelance o único sustento → 6–12.

Frequently asked questions

How much should I have in an emergency fund?
A common guideline is 3–6 months of essential expenses. Aim for 3 with stable dual income and few dependents, and 6–12 if you're a single earner, self-employed, or have dependents or variable income.
How is an emergency fund calculated?
Multiply your essential monthly expenses — rent/mortgage, food, utilities, insurance, minimum debt payments — by the months of cover you want. Use bare-bones survival spending, not your full lifestyle budget.
Where should I keep my emergency fund?
In a safe, liquid account you can access instantly without losing value — typically a high-yield savings account. Don't invest it in stocks; you may need it exactly when markets are down.
Is an emergency fund the same as a quit fund?
No. An emergency fund covers shocks while you're still employed. A quit fund must also cover lost income, health insurance and a longer runway, so it's usually larger — size the emergency layer first here.
