Emergency Fund Calculator
Find your target emergency fund size.
A common recommendation is 3–6 months of essential expenses.
How Big Should Your Emergency Fund Be
An emergency fund exists to cover essential expenses during a job loss, medical issue, or unexpected major cost, without forcing you into debt. This emergency fund calculator finds your target fund size based on your monthly essential expenses and how many months of coverage you want.
Why 3–6 months is the common range
Three months suits stable dual-income households with predictable expenses; six months or more is often recommended for single-income households, freelancers, or anyone in a less stable job market — the right number depends on your personal risk profile, not a universal rule.
What counts as “essential” spending
Essential expenses are the costs that continue regardless of income — housing, utilities, groceries, insurance, minimum debt payments. Discretionary spending like entertainment or dining out is typically excluded from this calculation, since it’s the first thing cut during an actual emergency.
Building the fund gradually
Reaching a full 3-6 month target doesn’t need to happen overnight — many people build toward it in stages, starting with a smaller $1,000 buffer before working toward the full target over time.
