How Big Should Your Emergency Fund Be Before a Career Change?
Hold two separate amounts. The first is an emergency cushion of three to six months of essential expenses, the range Fidelity and Vanguard both give for a loss of income. The second is a change fund that covers every month you plan to earn less during the move, plus what the move itself costs.
The cushion is for surprises, such as a car repair or a layoff at the new job. The change fund is spent on purpose, on a schedule you set before you give notice. Keeping them in two accounts means a slow start on the new path does not drain the money meant for an emergency.
Where the money sits: current rates
| Where you hold it | Typical rate | Insured or backed by |
|---|---|---|
| Savings account, national average | 0.37% | FDIC or NCUA, up to $250,000 per depositor per ownership category |
| Money market deposit account, national average | 0.63% | FDIC or NCUA, same limit |
| 12-month CD, national average | 1.73% | FDIC or NCUA, same limit |
| Top online high-yield savings accounts | about 4.00% to 4.50% APY | FDIC or NCUA, if the bank or credit union is insured |
| Treasury bills, 4 to 52 weeks | set at each auction | U.S. Treasury (not FDIC insured) |

Step 1: find your monthly essential expenses
Both amounts start from one figure, what you must spend in a month. Fidelity’s emergency fund guide lists the categories to count:
- rent or mortgage, plus utilities
- basic groceries
- health care and insurance premiums
- child care or tuition
- transportation
- minimum debt payments
Spending you could stop within a week, such as dining out, stays out of the figure.
Plan for health insurance separately if it now comes through your employer. Leaving a job usually changes that cost, and the new premium belongs in your essential figure for the months of the change.
If your income or spending moves around from month to month, Experian suggests basing the figure on a six-month average (Experian, September 2026).
Step 2: size the emergency cushion
Multiply your essential figure by a number of months between three and six. Vanguard sets a smaller target for a spending shock, such as a medical bill: at least half a month of expenses. For an income shock, such as a layoff, its target is three to six months.
Fidelity recommends going above six months if you work in an industry where layoffs or uneven income are common. A new field you are still learning, or freelance work with irregular pay, fits that description, so the top of the range is the safer starting point for someone in the middle of a change.
Step 3: size the change fund
The change fund has two parts. The first is your essential expenses multiplied by the number of months you expect to earn less than you need. The second is the direct cost of the move: tuition, certification fees, equipment, or the money to open a small business.
For the first part, plan on a longer gap than you hope for. In September 2026 the median unemployed person in the U.S. had been looking for work for 11.5 weeks, while the average was 24.8 weeks, close to six months (Bureau of Labor Statistics, Table A-12). The average sits far above the median because a minority of searches run much longer. These figures describe people who are unemployed, which is a different group from people changing careers by choice, but they show how wide the range of job-search times is.
If you plan to keep some income during the change, such as part-time work in your current field, subtract it from your essential figure for those months before you multiply.
A worked example
This example uses round numbers to show the arithmetic. Your own figures will differ, and the result is a savings target to plan around, with no guarantee about how the change will go.
| Line | Calculation | Amount |
|---|---|---|
| Monthly essential expenses | From Step 1 | $3,000 |
| Emergency cushion | $3,000 × 6 months | $18,000 |
| Change fund, months of reduced income | $3,000 × 4 months with no income | $12,000 |
| Change fund, direct costs | A certificate program, for example | $4,000 |
| Total to hold before giving notice | Cushion plus change fund | $34,000 |
In this example the cushion stays untouched unless something goes wrong. The change fund is drawn down month by month, and when it runs out you know the plan needs adjusting before the emergency money is at risk.
Where to keep each amount
The emergency cushion needs to be available within a day or two and safe from market losses. A savings account or money market deposit account at an FDIC-insured bank or NCUA-insured credit union meets both needs. The FDIC and the NCUA each insure deposits up to $250,000 per depositor per ownership category, and neither covers mutual funds or stocks. A money market mutual fund at a brokerage is a different product from a money market deposit account and is not FDIC insured.
The change fund has a known spending schedule, so part of it can sit in instruments that mature on that schedule. Treasury bills come in terms from 4 to 52 weeks, start at $100, and pay interest that is subject to federal tax but not state or local tax. A CD ladder works the same way inside the deposit-insurance limit. Keep the first few months of the change fund in savings so you are never waiting on a maturity date to pay rent.
