Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
What formula does the emergency fund calculator use?
It uses target fund = monthly essential expenses x target months of coverage, then remaining to save = target fund - current emergency savings. For example, $3,000 of monthly expenses with 6 months of coverage gives an $18,000 target; with $5,000 saved, $13,000 remains.
How many months of coverage should I target?
Common guidance is 3 to 6 months of essential expenses, with some households preferring up to 12 months for variable income or single earners. Enter whole months from 1 to 60 and treat the result as a planning starting point, not a recommendation.
Which inputs are accepted?
Enter monthly essential expenses greater than zero through 1000000000, whole-number target months from 1 to 60, and optional current savings from 0 through 1000000000000. Displayed amounts are rounded to two decimal places.
Do my values stay private, and is this financial advice?
