How to Build an Emergency Fund
An emergency fund is your financial safety net — liquid cash set aside specifically for unexpected expenses or income disruption. This calculator determines your target based on your monthly essential expenses multiplied by your chosen coverage period (3, 6, 9, or 12 months).
The formula is straightforward: Target = Monthly Essential Expenses × Coverage Months. Your shortfall is Target minus what you've already saved. The progress bar shows what percentage of your goal is funded, and the time-to-fund estimate divides your shortfall by your planned monthly savings rate.
The right coverage amount depends on your situation. Single-income households, freelancers, and those in industries with higher unemployment risk should target 9–12 months. Two-income households with stable employment can generally get by with 3–6 months. Longer coverage gives more peace of mind but has higher opportunity cost.
Once you've identified your target, open a dedicated high-yield savings account (separate from your checking account) and set up an automatic monthly transfer. Keeping emergency funds psychologically separated from everyday money reduces the temptation to spend them on non-emergencies.
