Assumptions and formula
The target is the monthly amount you would still have to pay out of work (essential spending less unemployment benefit or other income) times the months to cover. Months are set by your income situation: 3 with two stable incomes, about the median spell of unemployment; 6 with one income, about the average spell; 9 with variable or self-employed income.
The durations come from the Bureau of Labor Statistics, Employment Situation Table A-12, September 2026: a median of 11.5 weeks and an average of 24.8 weeks, with 27% of the unemployed out more than 26 weeks. The time to reach the target adds your monthly saving each month and the savings APY. The weeks your current fund lasts divide it by the monthly need.
Worked example
With $3,500 a month of essential costs and one income, the target is 6 × $3,500 = $21,000. $5,000 saved lasts about 6.2 weeks, under the 11.5-week median spell; saving $500 a month at a 4% APY reaches the target in 30 months. With $1,500 a month of unemployment benefit and variable income, the target is 9 × $2,000 = $18,000.
Frequently asked questions
How many months of expenses should an emergency fund cover?
About 6 with one income, matching the 24.8-week average spell of unemployment in September 2026; 3 with two stable incomes; 9 if your income varies.
How much should I have in an emergency fund?
Enough essential spending to last a typical job search: 3 months with two stable incomes, 6 with one, 9 if your income is variable or you are self-employed. With $3,500 a month of essential costs and one income, that is $21,000.
How long does it take to find a new job?
In September 2026 the median spell of unemployment in the U.S. was 11.5 weeks and the average 24.8 weeks, and 27% of unemployed people had been out more than 26 weeks (Bureau of Labor Statistics). The average is pulled up by long spells, which is why one-income households aim for about six months.
Should I count unemployment benefits?
Yes, conservatively. Benefits replace part of your wages for a limited number of weeks, set by your state. If $1,500 a month of benefits comes in against $3,500 of essential costs, the fund only has to cover $2,000 a month while they last.
Where should I keep my emergency fund?
In a federally insured, easy-access savings or money-market account. At a 4% APY, a $21,000 fund earns about $840 a year; at a typical 0.4% savings rate it earns $84.
How long will it take to build my emergency fund?
With $5,000 saved and $500 a month at 4%, a $21,000 target takes 30 months. Saving a tax refund or bonus into it shortens that quickly.
Is this an emergency savings calculator?
Yes: an emergency fund calculator and emergency savings calculator, showing how much emergency fund you need and how long it takes to build, as a rainy day fund calculator for any household.
How much is a 6 month emergency fund?
Six times your essential monthly spending: with $3,500 a month that is $21,000. This emergency fund savings calculator also gives the 3 month figure for two stable incomes and 9 months for variable income.
