Most early retirees keep one to three years of living expenses in cash and near-cash, such as high-yield savings, money market funds, Treasury bills or CDs. That cushion lets you pay the bills from cash during a market crash instead of selling stocks at low prices, which is the main defense against sequence-of-returns risk. Two years suits most people. One year works if your spending is flexible or you have other income; three suits very stock-heavy portfolios or nervous investors.
More isn’t automatically safer. Cash usually loses to inflation over time, so every extra year you hold costs you growth.
Why cash matters more in early retirement #
A crash right after you retire does the most damage, because you’re selling shares at low prices to live on and those shares never get to recover. That’s sequence-of-returns risk. Two retirees with the same average return can end up far apart depending on whether the bad years come first or last.
Early retirees face this for longer. A portfolio that has to last 40 or 50 years has more chances to meet a bad decade, and no paycheck to fall back on. A cash cushion breaks the link between a falling market and your grocery bill: you spend cash, leave the stocks alone, and refill the cash after prices recover. Our guide to protecting your portfolio from sequence of returns risk covers the other tools, like bond tents and flexible spending.
One, two or three years of cash? #
| Cushion | Suits | Upside | Downside |
|---|---|---|---|
| 1 year | Flexible spenders, people with part-time or rental income | Least cash drag | A long downturn can outlast it |
| 2 years | Most early retirees with an index fund portfolio | Covers most downturns without selling | Some cash drag |
| 3 years | Very stock-heavy portfolios or anxious investors | Lets you ignore long slumps | Real drag on long-run growth |
Things that let you hold less:
- Part-time income, as with Barista FIRE
- A flexible withdrawal method that cuts spending after bad years, such as variable percentage withdrawal
- A bond allocation you can sell instead of stocks
- Low fixed costs, like a paid-off house
Things that argue for more:
- A 90% to 100% stock portfolio
- High fixed costs you can’t trim
- A history of selling in a panic
Before choosing, test the whole drawdown. The Will My Money Last calculator in Retire Goals takes your portfolio, first-year spending and expected return, raises the withdrawal each year for inflation, and shows how many years the money covers and what you could spend to make it last 30. Run it at a lower return to see how much margin your plan has.
Where to hold early retirement cash #
Keep it safe and easy to reach, but not in a checking account earning next to nothing.
- High-yield savings accounts. Immediate access and FDIC or NCUA insurance up to $250,000 per depositor, per bank, per ownership category.
- Money market funds. Offered by brokerages, invested in short-term government and corporate debt. They’re not FDIC-insured, but government money market funds are very low risk.
- Treasury bills. Backed by the U.S. government, and the interest is exempt from state and local income tax, which helps in high-tax states.
- CD ladders. CDs maturing every few months lock in rates while releasing cash on a schedule.
Many retirees keep a few months in savings for immediate spending and the rest in T-bills or a money market fund.
How to refill your cash cushion #
The bucket approach #
- Bucket 1, cash: one to three years of spending. You pay your bills from here.
- Bucket 2, bonds and income: several years of spending in short- and intermediate-term bonds.
- Bucket 3, growth: everything else in stock index funds.
In good years, sell some stocks to refill cash. In bad years, leave the stocks alone and draw down cash, then bonds.
Rebalancing #
Simpler: hold a target mix, such as 80% stocks, 15% bonds and 5% cash, and rebalance once a year. After strong years you trim stocks, which refills cash. After weak years you spend cash and don’t sell stocks.
A tax bonus for early retirees #
Spending cash you already saved doesn’t count as income. In a year when you live mostly on cash, your taxable income can stay low, which can raise your ACA marketplace subsidy and open up low-tax room for Roth conversions. That’s one reason many early retirees build a larger cash pile just before they retire. Our guide to the Roth conversion ladder explains how those conversions work. Keep in mind that the interest your cash earns is taxable income.
The cost of holding too much cash #
Cash rarely beats inflation for long. Suppose you hold $150,000 more cash than you need for 30 years, earning 1% a year after inflation instead of 5% in a diversified portfolio. The cash grows to about $202,000 in today’s dollars; the portfolio would have grown to about $648,000. That’s roughly $446,000 of lost growth from being too cautious.
Treat cash as insurance. Buy enough to get through a bad stretch without selling, and no more.
Frequently asked questions #
Does my cash cushion count toward my FIRE number? #
Yes, it’s part of the portfolio you’ll spend. Because it earns less than stocks, a plan with a large cash share should assume a lower overall return, which may mean a slightly bigger FIRE number.
Should I keep more cash for Coast FIRE or Barista FIRE? #
Usually less. With a paycheck covering some or all of your spending, you rarely need to sell investments in a downturn. A normal emergency fund of three to six months of spending is often enough until you fully retire.
How often should I adjust my cash reserve? #
Review it once a year and after big changes, such as paying off a mortgage, moving or having a child. Base the target on your current spending, not the spending you had when you retired.
Is a money market fund as safe as a savings account? #
Nearly, but not identically. Bank savings accounts are FDIC-insured up to the limit; money market funds are not. Government money market funds invest in Treasury and agency debt and are considered very low risk, and they often pay more than savings accounts.
