An emergency fund keeps a job loss or a surprise bill from turning into debt. This calculator sets your target as a few months of essential expenses, then shows how much more you need and how many months of saving it will take to get there.
How this is calculated
The target fund is your monthly essential expenses multiplied by the number of months you want to cover, commonly 3 to 6 months. The shortfall is the target minus what you have already saved, floored at zero. The time to reach the goal is the shortfall divided by your monthly contribution, rounded up to whole months. This ignores interest earned, which is minor over a short savings horizon.
How to use
- Enter your essential monthly expenses (housing, food, utilities, insurance, minimum debt payments).
- Choose how many months of expenses you want to cover.
- Enter your current savings and how much you can add each month to see your target and timeline.
Examples
- $3,000/mo expenses, 6 months, $5,000 saved, $500/mo:
Target $18,000, shortfall $13,000, reached in 26 months - $2,500/mo expenses, 3 months, $8,000 saved:
Target $7,500, already fully funded
FAQ
- How many months should my emergency fund cover?
- Three to six months of essential expenses is the common guideline. Lean toward six or more if your income is variable or you are a single earner, and toward three if you have very stable pay.
- Which expenses should I include?
- Only essentials you would still owe if your income stopped: rent or mortgage, utilities, groceries, insurance, transport, and minimum debt payments. Leave out discretionary spending.
- Where should I keep the money?
- In a liquid, safe account such as a high-yield savings account, so it is available quickly without market risk. This tool does not assume investment returns for that reason.
