Emergency Fund Calculator
Find your emergency fund target and how long it takes to reach it.
This tool runs entirely in your browser. Your files are never uploaded to a server.
Savings toward the target are assumed to sit in cash without earning a return, since emergency funds are typically kept liquid rather than invested for growth.

What this calculator does
Multiplies monthly essential expenses by a chosen number of coverage months to set an emergency fund target, compares it with current savings, and estimates the months needed to close the gap at a flat monthly savings rate.
How to use it
Enter monthly essential expenses, the number of months of coverage you want, current emergency savings, and the monthly amount you can set aside. Keep every amount in one currency.
Worked example
With 2,500 in monthly essential expenses, 6 months of desired coverage, 1,000 already saved, and 300 saved per month, the target is 15,000, the gap is 14,000, and closing it takes 47 months. Automated tests verify this figure.
Formula
Target = monthly essential expenses × coverage months. Gap = max(0, target − current savings). Months to target = gap ÷ monthly savings, rounded up to a whole month; the result is 0 once the gap is already closed, and shown as unresolved when a gap remains but no monthly amount is entered.
Why no investment return is assumed
Unlike the other savings tools in this cluster, this model does not compound a return on the growing balance. Emergency funds are conventionally held in cash or a highly liquid account so they can be accessed immediately without selling investments at a loss, so this tool intentionally leaves compounding out.
Choosing a coverage target and defining "essential"
There is no single correct number of months; it depends on income stability, dependents, insurance coverage and job security. "Essential" spending is commonly limited to housing, utilities, groceries, insurance, minimum debt payments and other costs that continue regardless of income — discretionary spending is normally excluded so the target reflects a bare-minimum survival budget.
Scope, sources and privacy
This is an educational estimate, not financial advice. The 3-6 month guideline and the definition of essential expenses follow consumer-finance guidance from the U.S. Consumer Financial Protection Bureau and the FINRA Investor Education Foundation.

Frequently Asked Questions
- Why doesn't this model apply any investment return to my savings?
- Emergency funds are meant to be accessed immediately without selling investments at a loss, so this tool assumes the balance sits in cash rather than compounding — the future-value calculators in this cluster are the place to model an invested balance.
- How is the number of months to reach my target rounded?
- The gap is divided by your monthly savings amount and rounded up to the next whole month, since a fund that is one dollar short of the target for part of a month still isn't complete until the following contribution.
- What happens if I already have more saved than my target?
- The gap shows as zero and the months-to-target figure is zero — the calculator does not report a negative gap or suggest withdrawing the surplus.
