Calculadora de Reserva de Emergência

This emergency fund calculator helps you determine the ideal size of your financial safety net based on your monthly expenses, income stability, and personal risk factors.

1. Enter your total monthly expenses. Include all essential spending: housing, utilities, groceries, insurance, minimum debt payments, transportation, and other necessary costs. Do not include discretionary spending like entertainment or dining out.
2. Assess your job stability. Select whether your employment is very stable (tenured, government, established role), moderately stable (typical employment), or unstable (contract work, commission-based, seasonal).
3. Indicate your number of dependents. Enter how many people rely on your income, including children and other family members you financially support.
4. Consider your health and other risk factors. Account for chronic health conditions, high-deductible insurance, homeownership maintenance needs, or other circumstances that increase the likelihood of unexpected expenses.
5. Enter your current emergency fund balance. Input how much money you currently have set aside in easily accessible savings specifically for emergencies.
6. Review your recommended fund size. The calculator suggests a target amount based on 3-6+ months of expenses, adjusted for your specific risk profile.

The results show your target emergency fund size, how close you are to that goal, and how long it will take to reach your target based on different monthly savings rates. Focus on building this foundation before pursuing other financial goals.

Why 3-6 Months of Expenses?

The standard recommendation of 3-6 months of expenses is based on historical data about how long it takes to find new employment and the typical duration of common financial emergencies. Three months is the minimum for those with stable jobs, dual incomes, and low risk factors. Six months or more is recommended for single-income households, self-employed individuals, those with variable income, or anyone in specialized fields where job searches take longer.

What Qualifies as an Emergency?

True emergencies are unexpected, necessary, and urgent expenses: job loss, medical emergencies, major car repairs needed for work commute, essential home repairs like a broken furnace, or unexpected essential travel. Not emergencies: holiday gifts, vacations, weddings, new electronics, or predictable annual expenses like car registration. Many people drain emergency funds for non-emergencies, leaving themselves vulnerable when real crises occur.

Where to Keep Your Emergency Fund

Emergency funds must be liquid (quickly accessible) and stable (not subject to market volatility). The best options are high-yield savings accounts or money market accounts that offer FDIC insurance, easy access, and competitive interest rates of 4-5% in many cases. Avoid keeping emergency funds in checking accounts that earn no interest, CDs with withdrawal penalties, or investments like stocks that could lose value when you need the money most.

Building vs Maintaining the Fund

Building an emergency fund from zero feels overwhelming, but consistency matters more than amount. Start with a mini-goal of 1,000, then work toward one month of expenses, then three, then six. Automate transfers to make saving effortless. Once fully funded, your emergency fund requires minimal maintenance—just replenish it after withdrawals and periodically verify the interest rate remains competitive. This is a "set it and forget it" asset.

Opportunity Cost of Holding Cash

Money in an emergency fund earns lower returns than stock market investments, creating an opportunity cost. However, this "cost" is actually insurance premium—you pay for peace of mind, financial stability, and the ability to weather crises without derailing long-term goals or going into debt. The real cost of not having an emergency fund is far higher: forced stock sales during market downturns, high-interest debt, or financial ruin. An emergency fund is not an investment; it is a foundation that enables all other investments.
