Emergency Savings Months Calculator
See how many months of expenses your emergency fund covers, and the gap to a 3-, 6- or custom-month cushion.
How it works
Months covered = savings ÷ monthly expenses · Target = monthly expenses × target months · Gap = target − savings
Your emergency fund is measured in months, not dollars: divide what you have saved by your essential monthly spending to see how long you could cover the basics with no income. A common guideline is three months for stable dual-income households and six months (or more) for single earners, commission work or anyone with dependents. Base the calculation on essential expenses — rent, food, utilities, insurance, minimum debt payments — not your full lifestyle budget, so the cushion reflects true survival costs.
Worked example
With $12,000 saved and $4,000 of essential monthly expenses, you have 3 months of runway. A 6-month cushion would need $24,000, so you are $12,000 short.
Frequently asked questions
How many months should an emergency fund cover?
Three to six months of essential expenses is the usual range. Lean toward three if you have very stable, dual income and low fixed costs, and toward six or more if you are self-employed, a single earner, or support dependents.
Should I use gross income or expenses?
Use essential monthly expenses, not income. The fund exists to keep you afloat if income stops, so what matters is the minimum you must spend each month — housing, food, utilities, insurance and minimum debt payments.
Where should I keep an emergency fund?
In something safe and liquid — a high-yield savings or money market account you can access within a day or two. The goal is availability and stability, not maximum return.
