How Big Should Your Shutdown Emergency Fund Be?

Last verified: October 28, 2026, against the sources linked below. Written by Casey Steward.

Federal funding runs through December 11, 2026 (P.L. 119-103). Nobody knows whether Congress will extend it. What we do know is how long recent shutdowns lasted, and that number is the best guide to how much cash you should keep on hand. This post turns it into a dollar figure, using the same GS-12 step 5 paycheck from our GS-12 budget post.

The short version

  • Size the fund by your bills, not your salary. Add up one month of must-pay bills. That’s your unit.
  • Two months of bills covers every broad shutdown on record. The longest ones lasted 34 days (2018-19) and 42 days (fall 2025) (CRS, RS20348).
  • Three months covers the worst recent case. The 2026 lapse that hit only the Department of Homeland Security lasted 75 days.
  • In our example, that’s about $5,284 for two months and $7,926 for three. That’s for a GS-12 step 5 whose must-pay bills are half of take-home pay.
  • Keep it boring and reachable. An insured savings account you can move money from in a day or two. Not the TSP, and not a credit card.

Why a shutdown is its own kind of emergency

A shutdown doesn’t usually cost you money in the end. It costs you time. Federal law says employees get paid for the lapse once it ends (31 U.S.C. 1341(c)). But “once it ends” can be weeks away, and your landlord doesn’t take IOUs.

So a shutdown fund is a bridge. It needs to cover your bills until back pay shows up, and then you refill it from the back pay. Our shutdown guide covers back pay, benefits, and leave in detail. This post is just about the cash.

How long shutdowns actually last

Most funding gaps are short. About half since 1977 lasted three days or less. The recent ones have been longer (CRS, RS20348).

Funding gapLengthWho it hit
October 201316 daysGovernmentwide
December 2018 to January 201934 daysAgencies without full-year funding
October 1 to November 12, 202542 daysGovernmentwide
January 31, 20263 daysAgencies under six of the 12 spending bills
February 14 to April 30, 202675 daysDepartment of Homeland Security only

Lengths are full days without funding, as CRS counts them. The short answer: plan for about six weeks, and plan for longer if your agency’s bill is the one Congress is fighting over.

What a shutdown would cost a GS-12 step 5 in paychecks

Here’s the example paycheck again. A GS-12 step 5 earns $101,443 on the 2026 Rest of U.S. table (OPM). After FERS, 5% to the TSP, self-only health insurance, basic life insurance, and federal taxes, our example takes home about $2,641.87 every two weeks, before state tax. The budget post shows every line.

Shutdown lengthPaychecks delayed (approx.)Take-home delayed, GS-12 step 5 example
1 to 2 weeksNone, or 1 partialUp to $2,642
3 weeks1 full, plus a partial$2,642 to $5,284
6 weeks (like fall 2025)3$7,926
11 weeks (like the 2026 DHS lapse)5 to 6$13,209 to $15,851

That last row looks scary. But you don’t need to replace every paycheck. You need to pay your bills. That’s a smaller number.

Size the fund by your bills

Start with one month of must-pay bills. These are the ones with late fees or worse: rent or mortgage, utilities, car payment, insurance, minimum debt payments, childcare, and a basic grocery budget. Leave out eating out, travel, subscriptions, and extra debt payments. Those can pause.

In our budget post, needs are about half of take-home, or $2,641.87 a month. Here’s how that turns into a fund:

Fund sizeGS-12 step 5 exampleWhat it covers
One month of bills$2,642A short lapse, or one or two delayed checks. A good first goal.
Two months of bills$5,284Every broad shutdown so far, with a little room for back pay to arrive.
Three months of bills$7,926A 75-day lapse like the 2026 DHS one, or a shutdown plus a car repair.

Two months is the sweet spot for most federal employees. Go to three if you work at an agency whose funding is in the middle of the fight, if you’re the only income in your household, or if your bills run well over half your pay.

If you have a partner with a non-federal paycheck, you can size the fund to the gap between their income and your shared bills instead. That can shrink the number a lot.

Where to keep it

An emergency fund has one job: be there, in full, when you need it. That rules out anything that can drop in value or takes weeks to reach.

  • Good: an insured savings or money market account. Banks are covered by FDIC insurance and credit unions by NCUA insurance, generally up to $250,000 per depositor, per institution, per ownership category (FDIC; NCUA). Many online banks pay more interest than a typical checking account. Pick one you can transfer from in a day or two.
  • Fine for part of it: Treasury bills or a money market fund. These are reachable in a few days but aren’t instant, and a money market fund isn’t FDIC insured.
  • Not an emergency fund: your TSP. Taking money out while you’re still working is limited to hardship or age 59½. A hardship withdrawal is taxed, can carry a 10% early-withdrawal tax before 59½, and can never be paid back (IRS, Topic 558). A TSP loan is a better backup, but it’s a loan, not savings. See our TSP loans guide.
  • Not an emergency fund: a credit card. It’s a way to pay for an emergency, not a way to be ready for one.

How to build it before December 11

You probably have three or four paydays between now and December 11. Your payroll calendar has the exact dates. That’s not enough time to save two months of bills from scratch, and that’s OK. A one-month fund by December, and two months by spring, is a solid plan.

  • Automate it. Send a fixed amount from each check straight into the savings account. Many payroll systems let you split your direct deposit between accounts; ask your payroll office or check your payroll self-service site.
  • Use the 20% bucket. In our budget, the savings-and-debt bucket is about $1,056.75 a month. If all of it went to the fund, two months of bills ($5,284) would take five months.
  • Grab the windfalls. Twice a year you get a third paycheck in a month. That check alone is $2,641.87 in our example, or one month of bills. Tax refunds and the January raise can go here too.
  • Pause, don’t stop, extra debt payments. If you’re paying extra on a low-rate loan, redirect that extra to the fund until you hit one month. Keep paying the minimums.

If a shutdown hits before the fund is full

Use cash in this order:

  1. Your emergency fund.
  2. Interest-free help. Many banks and credit unions have offered no-interest shutdown loans or payment deferrals to federal employees in past lapses. Ask yours now what it would offer.
  3. Call your creditors early. Lenders and landlords often work with you if you call before a missed payment, with a furlough notice in hand.
  4. A TSP loan. The TSP allowed new loans during recent lapses and kept existing loans in good standing automatically (TSP, Feb 13, 2026). Run the numbers with the TSP loan calculator.
  5. Credit cards, last. Payday loans, never.

Furloughed employees may also be able to collect unemployment, but in most states you’ll have to pay it back once back pay arrives (OPM guidance, I.1). Our shutdown guide has the details.

After the shutdown: refill it

When back pay lands, it can be a big deposit all at once. Before anything else, put back what you took out of the fund. Then pay off anything you put on a credit card. Watch for health and life insurance premiums that pile up during the lapse; they come out of later pay (OPM guidance, section H).

The details

The paycheck math. Take-home of $2,641.87 per check assumes a single filer hired in 2014 or later (4.4% FERS), 5% traditional TSP, FEP Blue Basic self-only, FEGLI Basic, the 2026 federal brackets and standard deduction, and no state tax. The full table and sources are in our GS-12 budget post. Delayed-paycheck counts in the table are approximate; the exact count depends on where the lapse falls in the pay period.

The “half of take-home” bills figure comes from the 50/30/20 starting budget in that post. It’s an example, not a measurement. Use your own number.

Back pay. The 2019 law says furloughed and excepted employees are paid after a lapse ends. In October 2025, the Office of Management and Budget argued that law isn’t automatic, and Congress has written back pay into the bills ending recent lapses. Our shutdown guide explains the disagreement.

Not everyone is affected. Employees whose pay doesn’t come from annual appropriations keep getting paid during a lapse. Ask your agency which group you’re in.

FAQ

How many months of expenses should a federal employee save?

For shutdowns alone, two months of must-pay bills has covered every broad shutdown so far. Three months gives room for a long single-agency lapse or a second emergency on top of one.

Should I save my whole paycheck or just my bills?

Just your bills. During a shutdown you can pause wants and extra savings. The fund only needs to cover what can’t wait.

Is it smarter to pay off debt or build the fund first?

Many people do both: build one month of bills first while paying minimums, then put more toward debt. A small fund keeps a surprise from going on a credit card and undoing your debt progress.

Can I use the TSP G Fund as my emergency fund?

Not really. The G Fund doesn’t lose value, but money in the TSP is hard to reach while you’re working. Your options are a loan or a taxable hardship withdrawal. Keep emergency cash in a bank or credit union.

Will I get back pay if there’s a shutdown?

Every recent lapse has ended with back pay, but it arrives after the shutdown ends. That delay is exactly what this fund is for.
