Emergency Fund Calculator
Emergency Fund Calculator
How big an emergency fund to aim for, in months of essential expenses, how far you are from it, and how many months of saving will close the gap. The month count is a rule of thumb, not a rule.
Emergency fund target
Essentials of $40,000 a month, a stable salary, one or two dependants, $50,000 saved and $15,000 a month to add
Target, gap and time to close it
- months
- 3, 6 or 9 by how secure your income is, plus 0, 1 or 2 for dependants — or your own figure
- savings
- money you can reach within days without a loss
- monthly saving
- what you add each month. Interest on the fund is left out, so the time is slightly cautious.
Worked example
Essentials of $40,000 a month, a stable salary, one or two dependants, $50,000 saved and $15,000 a month to add
Months: 3 for a stable salary + 1 for dependants = 4
Target = 40,000 × 4 = $1,60,000
Gap = 1,60,000 − 50,000 = $1,10,000
1,10,000 ÷ 15,000 = 7.3 months, so the fund is complete in month 8
Target for essentials of 40,000 a month
| Situation | Months | Target |
|---|---|---|
| Stable salary, no dependants | 3 | $1,20,000 |
| Stable salary, one or two dependants | 4 | $1,60,000 |
| One less-secure income, one or two dependants | 7 | $2,80,000 |
| Irregular income, three or more dependants | 11 | $4,40,000 |
Three to six months is a rule of thumb — here is where it comes from
The figure you will hear most often is three to six months of expenses. It is advice, not a rule. FINRA, the US brokerage regulator, puts it as “financial planners often recommend the equivalent of three to six months of living expenses”, adding that people with variable income or specialised careers might need more than those with stable jobs. The US Consumer Financial Protection Bureau does not give a number at all: it says the amount depends on your situation, and that even a small fund helps.
So this page turns the rule of thumb into a number openly. It starts at 3 months for a stable salary or a two-income household, 6 for a single or less secure income, and 9 for self-employed or irregular income, then adds a month for one or two dependants and two for three or more. Those steps are a convention, not research; change them with your own number of months. Count essential spending only, because in an emergency the extras stop. Include insurance premiums and loan EMIs, which do not.
The money should be reachable within days without a loss: a savings account, a sweep deposit, or a fixed deposit that can be broken, knowing that breaking one early usually costs a little interest. It is not the place for equity funds, which may be down exactly when you need them, and a credit card limit is not an emergency fund. Health insurance does a different job: it covers a large bill that a few months of expenses would not.
The time to close the gap ignores interest on the fund, so it is slightly cautious, and it assumes your expenses stay where they are; review the target as they rise with inflation. To plan the monthly saving towards it, try the savings goal calculator; to see how a deposit would grow, the RD calculator or the FD calculator. This is arithmetic on the figures you enter, not financial advice.
Frequently asked questions
How many months of expenses should an emergency fund cover?
Three to six months is the common rule of thumb; FINRA describes it as what financial planners often recommend, with more for variable incomes. It is not a regulation. This page suggests 3 to 11 months depending on your income and dependants, or you can choose your own number.
Does the CFPB recommend three to six months?
No. The US Consumer Financial Protection Bureau says the amount depends on your situation and gives no month figure.
Where should I keep an emergency fund?
Somewhere you can reach within days without a loss, such as a savings account or a deposit you can break. Not in investments whose value can fall.
Should I count EMIs and insurance premiums as expenses?
Yes. They keep falling due in an emergency, so they belong in essential expenses.
