An emergency fund is the financial cushion that lets you absorb an unexpected event — an illness, a layoff, a car repair — without going into debt or touching your long-term savings. The general rule says you should have between 3 and 6 months of fixed expenses saved in a safe, liquid place. Without that cushion, you are one unexpected event away from a financial crisis. Here is how to build it in 90 days.
Add up your fixed monthly expenses: rent or housing payment, utilities, food, transportation, school fees, and any debt you must pay no matter what. Do not include discretionary spending (clothing, entertainment). That number multiplied by 3 is your minimum emergency fund target. If you earn variably or depend on a single income source, aim for 6 months. An employee with stable work may be fine with 3 months; a freelancer should have 6.
Month 1: Calculate your exact target and open a separate account just for the emergency fund (a different bank from your main account helps keep it untouched). Automate a fixed transfer on the day you receive income — even if it is just 5% of what you earn. Auto-saving works because it removes the decision. Month 2: Find one temporary extra income source (selling things, freelance work, overtime) and direct 100% of it to the fund. Month 3: Review your subscriptions and recurring expenses — typically $100,000–$300,000 per month goes to services you barely use. Redirect that money to the fund.
The emergency fund is NOT for risky investing. It needs two qualities: safety and liquidity. The best options in Colombia are: a high-yield savings account (some fintechs offer 6–8% per year with daily liquidity), or a 30-day CD that auto-renews. Do not put it in stocks, variable-income funds, or cryptocurrency — you might need it exactly when the market is down.
Rule 1: Only for real emergencies (not vacations, not discounts, not "opportunities"). Rule 2: When you use it, replenishing it becomes your top priority. Rule 3: Review it every year — if your fixed expenses went up, the target goes up too. Rule 4: Once you reach the target, that money stays there. Do not touch it for investments or for anything that is not a genuine emergency.
