The best way to build an emergency fund is to automate it: send a fixed amount to a separate savings account on payday, aim first for a small cushion such as $1,000, and then build toward about three months of essential expenses. The monthly amount matters far more than the interest rate in the early months. At $100 a month, $1,000 takes 10 months at both rates in the table below, while a full three-month fund can take from under 3 years to nearly 15 years depending on the deposit and the rate.
Key takeaways
- Splitting direct deposit, dividing a tax refund and adding windfalls move money before it reaches daily spending, which is why they tend to work better than saving "what is left."
- In the illustrative timeline below, reaching $1,000 takes the same number of months at 0.38% and 4% (20, 10 and 4 months at $50, $100 and $250 a month); a $9,000 fund takes 34 fewer months at $50 a month with the higher rate.
- As of October 19, 2026, the FDIC lists a national savings rate of 0.38%.
- Employers may offer a pension-linked emergency savings account (PLESA) to workers who are not highly compensated, capped at $2,600 of contributions in 2026, and retirement plans and IRAs may allow one emergency withdrawal per calendar year of up to $1,000 without the 10% additional tax; that money comes out of retirement savings and is generally still counted as income.
- In the Federal Reserve's 2025 survey, 63% of adults said they would cover a $400 emergency with cash or its equivalent, the same share as in each of the previous three years.
Pick a first target you can reach
A full emergency fund is a large number, and a distant goal is easy to postpone. Splitting the project into two stages gives an early finish line: a starter cushion for small shocks (a car repair, a deductible, a medical copay), then a larger reserve measured in months of essential spending. The $1,000 starter figure is a common rule of thumb, not a regulatory standard; a household with high deductibles or an older car may want a higher first target.
How large the full reserve should be depends on income stability, dependents and fixed costs, and that question is separate from how to build one. For the timeline below, the second stage uses three months of essential expenses, and the example assumes $3,000 a month, so the target is $9,000. Swap in your own figure.
The Federal Reserve's annual household survey shows why a first cushion is a meaningful goal. In the survey fielded October 17 to 28, 2025, 63% of adults said they would cover a hypothetical $400 expense with cash or its equivalent, meaning cash, savings, or a credit card paid off at the next statement. That share is the same as in the previous three years and below the 2021 high of 68%. The Fed's data table shows the series starting at 50% in 2013. Because "cash equivalent" includes a card paid in full, 63% is not the share with a funded emergency account, and the same report says the share able to cover three months of expenses with a rainy-day fund was unchanged from the prior year.
Ways to build an emergency fund
Most people do not find an extra $250 in a monthly budget by willpower. The approaches below work by moving money before it is spent.
Split direct deposit
If an employer offers direct deposit and allows the paycheck to be split, a chosen amount can land in savings and the rest in checking. The Consumer Financial Protection Bureau describes this as helpful for people who tend to spend most of a paycheck before the next payday. A recurring bank-to-bank transfer on payday is the fallback; the CFPB notes that some institutions set a minimum for automatic transfers, and that you can start at the minimum and raise it later.
Divide the tax refund
Form 8888 lets a filer direct deposit a refund, or part of it, to accounts at a US bank, credit union or other financial institution. The form's instructions (Rev. December 2025) set the conditions: the refund can be split between two or three accounts, each account must be in the filer's name, the split is not available to a filer who files Form 8379 (Injured Spouse Allocation), and for a single account the filer simply requests direct deposit on the return instead. Sending part of the refund to the savings account at filing time avoids the step where the money first lands in checking.
Windfalls and raises
Bonuses, money from a sold item or a raise are often easier to redirect than regular pay, because the household budget is not yet built around them. A simple rule, such as sending half of every windfall to the emergency account until the target is reached, needs no monthly decision.
Round-ups
Some banks and apps round up debit purchases and move the difference to savings. The CFPB cautions that the amounts are small, so progress should be reviewed and other saving adjusted as needed. Treat round-ups as a supplement to a fixed transfer, not as the plan.
How long it takes, by the month
The table shows months needed to reach each target when depositing a fixed amount at the end of every month, starting from zero, with interest compounded monthly. Two rates are used: 0.38%, the FDIC national rate for savings accounts as of October 19, 2026, and 4.00%, an assumed high-yield rate chosen for illustration. The FDIC's national rate is a deposit-weighted average across institutions, so many accounts pay more and many pay less. Actual rates change, vary by bank and may carry conditions. (The 4.63% national rate cap on the same page is not a market rate; it limits what banks that are less than well capitalized may pay.)
Illustrative example. Targets are $1,000 and $9,000 (three months at $3,000 of essential expenses). Months are rounded up to the month in which the balance first passes the target.
| Monthly deposit | $1,000 at 0.38% | $1,000 at 4.00% | $9,000 at 0.38% | $9,000 at 4.00% |
|---|---|---|---|---|
| $50 | 20 months | 20 months | 176 months (14.7 years) | 142 months (11.8 years) |
| $100 | 10 months | 10 months | 89 months (7.4 years) | 80 months (6.7 years) |
| $250 | 4 months | 4 months | 36 months (3.0 years) | 35 months (2.9 years) |
The formula behind the table:
balance_n = balance_(n-1) × (1 + APY)^(1/12) + deposit
Here balance_n is the balance after month n, APY is the annual percentage yield (0.0038 or 0.04), and deposit is the fixed monthly amount. The loop stops at the first month where the balance reaches the target.
Two conclusions follow from the numbers. First, for the $1,000 starter cushion, the rate is nearly irrelevant: interest adds about $3.01, $1.42 and $0.47 at the low rate and about $31.72, $14.86 and $4.92 at the high rate for the $50, $100 and $250 deposits, which never changes the month count. Second, the rate matters for the large target, but mostly when deposits are small. At $50 a month, 4.00% shortens the path by 34 months (142 instead of 176) and earns about $1,920 in interest, against about $248 at 0.38%. At $250 a month it saves one month; interest is about $505 against about $50.
Raising the deposit helps more than chasing the rate: going from $50 to $100 a month at 0.38% cuts the $9,000 timeline by 87 months (176 to 89), while moving the $50 deposit from 0.38% to 4.00% cuts it by 34, and a higher rate is still worth having once the balance is large.
Emergency savings through work
SECURE 2.0 added two workplace routes. Both depend on the employer and the plan, so neither is available to everyone.
Pension-linked emergency savings accounts (PLESAs)
A PLESA is a short-term savings account that an employer can attach to its defined contribution plan, such as a 401(k). Per the IRS and the Department of Labor, the main conditions are:
- Who: employees who meet the plan's eligibility rules and are not highly compensated employees (an employee who later becomes highly compensated can withdraw the balance but cannot keep contributing); employers may offer PLESAs for plan years beginning after December 31, 2023, and the DOL describes them as a feature plans may include, not a requirement.
- Cap: the law sets $2,500 of contributions, indexed for inflation; IRS Notice 2025-67 raised it to $2,600 for 2026. The employer may set a lower limit, and the cap applies to the part of the balance that comes from contributions, although the DOL says a plan may also count earnings toward it.
- Tax: contributions are Roth, meaning after-tax; the IRS says contributions are not deductible but withdrawals are generally tax-free.
- Access: withdrawals at least once per calendar month, at the participant's discretion and with no need to show or certify an emergency; the first four withdrawals in a plan year cannot carry fees, and later ones may carry reasonable fees.
- Participation: never mandatory. A plan may auto-enroll workers at no more than 3% of pay after written notice, and workers can opt out and withdraw their money without charge.
- Match: if the plan has a match, PLESA contributions receive the same rate, but the matching funds go to the retirement account, not the PLESA.
A PLESA works as a payroll-deducted version of the automatic transfer described above, and the 2026 cap of $2,600 means it can hold a starter cushion rather than the full fund.
The $1,000 emergency withdrawal
A separate SECURE 2.0 provision, Internal Revenue Code section 72(t)(2)(I), exempts an "emergency personal expense distribution" from the 10% additional tax that generally applies to withdrawals before age 59½. The distribution must be for unforeseeable or immediate financial needs from necessary personal or family emergency expenses; the plan administrator may rely on the person's written certification. The limit is the lesser of $1,000 or the account balance above $1,000, and only one such distribution can be counted per calendar year. The IRS says the exception applies to distributions after December 31, 2023, from qualified plans such as a 401(k) and from IRAs. Under IRS Notice 2024-55, the $1,000 is not indexed for inflation, defined benefit pensions are excluded, and plans are not required to offer this distribution. If a plan does not offer it, a distribution the plan otherwise allows (such as a hardship withdrawal) can still be claimed as an emergency personal expense distribution on Form 5329 if it meets the same limits.
This is retirement money. The statute waives only the 10% additional tax: Notice 2024-55 states that the distribution is still includible in gross income, and it does not make the withdrawal a savings account. It is better viewed as a backstop for a household still building its fund than as the fund itself.
Frequently asked questions
Does the interest rate matter when I am just starting?
Very little for a $1,000 cushion: in the timeline above, interest adds between about $0.47 and $31.72 depending on the deposit and rate, and the number of months does not change. It matters more once the balance is in the thousands, and most for small monthly deposits aimed at a three-month fund.
Can I split my tax refund between savings and checking?
Yes, between two or three accounts. Each account can be a checking, savings or certain other account, such as a traditional or Roth IRA (not a SIMPLE IRA) or an HSA, at a US financial institution, and it must be in the filer's name. The form instructions also say no more than three refunds a year can be deposited to the same account or prepaid card.
Are round-up apps enough to build a fund?
Usually not on their own. The CFPB notes the amounts are small and advises reviewing progress and adjusting other saving efforts. A fixed transfer sets the pace, with round-ups as extra.
Does my employer have to offer an emergency savings account?
No. The Department of Labor describes PLESAs as a feature a plan may include, and employee participation cannot be mandatory. Ask the plan administrator whether the plan offers one and what its cap, fees and match rules are.
Can I repay the $1,000 emergency withdrawal?
Yes. Under the statute and Notice 2024-55, any part of it can be repaid during the 3-year period that begins the day after the distribution is received, to a plan that accepts rollovers from the person. Until the earlier withdrawal is fully repaid, or new contributions to that plan at least equal the unrepaid amount, no later distribution from the same plan can be treated as an emergency personal expense distribution during the next 3 calendar years. Whether a particular plan offers the withdrawal is a plan decision, so confirm with the administrator.
Four steps to start this week
- Open a separate savings account used only for emergencies, so the balance is visible and not mixed with checking.
- Choose a monthly amount and set it as a split direct deposit or a payday transfer; use the timeline above to see what it buys.
- Decide in advance what share of the next tax refund, bonus or raise goes to the account, and file that choice (for a refund, on Form 8888).
- Ask the plan administrator whether a PLESA is available and what the cap, fees and match rules are, and treat the $1,000 emergency withdrawal as a last resort.
