Bucket 1: Cash
The next 2 years of living expenses. Cash can lose purchasing power when its interest trails inflation.
Give your money a purposeMeasure it in time
Time is money. Flip that around: money is time when you measure it against your lifestyle. A dollar amount alone doesn’t tell you much. At $60,000 in annual lifestyle spending, $120,000 represents about two years of lifestyle spending. For another household, the same balance might last much longer or much less. Ask how much time the money buys and when you’ll need it.
Cash buys the present. Fixed income buys the near future. Equities buy the distant future. Give each year’s money a job before choosing investments:
Bucket 2: Fixed income
The following 3 years (years 3–5), with bonds, CDs, or Treasury Inflation-Protected Securities (TIPS) matched to later expenses.
Bucket 3: Equities
Money needed beyond year 5 can stay in stocks for long-term growth.
This site’s starting structure is 2 / 3 / 15+. Next, see the order for filling the buckets. More on the bucket sizing...
The funding sequenceFill the buckets through each phase
Compare the estimated timing below, or explore the calculator to see how each funding method works and adjust savings and return assumptions.
-
Accumulation Phase
Save an emergency fund
First establish the appropriate emergency reserve in Bucket 1. How much should it hold? While building it, contribute enough to an employer retirement plan to receive the full match offered—but no more until the emergency fund is complete.
Consider a Vanguard Cash Plus Account or another similar high-yield savings account (HYSA).
What if VT isn’t available? Scan the choices available and compare expense ratios: the annual percentage charged to operate each fund. Favor the lowest-cost broad index funds labeled “total market” wherever possible. See VT alternatives for example fund combinations.
-
Accumulation Phase
Build at least 15 years in Bucket 3
For the 5% example, direct long-horizon savings to equities, preferably through VT, until Long-Term Growth covers at least 15 years of annual expenses. This is the “messy middle”* of the accumulation phase, and it takes the longest. Just keep buying on an automated basis.

Nearing Retirement Phase
Build 3 years in Bucket 2
After Long-Term Growth covers 15 years of expenses in equities, you are nearing retirement. Build a bond ladder in Bucket 2 to cover the three years before cash would need replenishment and help minimize sequence-of-returns risk (SORR*) in early retirement.

Finally grow cash beyond the emergency reserve to the full two-year target, completing this example’s 2/3/15+ minimum. Fully filling the cash bucket is the final step to glide into retirement, giving you cash to live on in early retirement.

How much emergency cash?Start with your household
The site’s Financial Next Step rule starts with three months of lifestyle expenses. It doubles that target separately for uncertain employment, self-employment income, and having at least one dependent. Depending on which factors apply, the result is 3, 6, 12, or 24 months of expenses. At $5,000 per month, a six-month reserve is $30,000.
That rule is a planning starting point, not a universal requirement. Consider your income stability, the people who rely on it, and the surprise costs your household has faced. The funding timeline above uses a six-month reserve for illustration; your own target may differ. This reserve counts toward Bucket 1’s eventual two-year retirement cash target; it is not an extra bucket.
Account locationPut each bucket in a tax-aware home
Asset allocation decides what you own; account location decides where you hold it. Keep the three-bucket target primary, then use available account space to reduce avoidable tax drag.
A sample order for filling accounts
- 401(k) up to the full employer match
- Roth IRA up to the annual limit
- 401(k) up to the annual limit
- After-tax brokerage for additional investing
This is one sample order for filling accounts. Eligibility, contribution limits, current and expected future tax rates, and access needs may favor a different sequence—or traditional contributions instead of Roth.
Cash stays accessible
Keep money needed soon in accounts you can reach without retirement-plan restrictions or early-withdrawal consequences. Compare yield, insurance coverage, and settlement timing.
Fixed income favors tax-advantaged space
When practical, hold taxable bonds and other interest-producing fixed income in tax-deferred or tax-free accounts because their income is often less tax-efficient. Access needs, account rules, and tax-exempt municipal bonds can change that choice.
Broad equities can fit taxable brokerage
Long-term index funds such as VT can work well in an after-tax brokerage because qualified dividends and long-term capital gains may receive favorable treatment, and taxable accounts preserve flexible access. Retirement accounts can still hold equities when that best supports the overall allocation.
This is general educational guidance, not individualized tax advice. Account eligibility and annual contribution limits apply. Rebalancing inside a tax-advantaged account can avoid realizing taxable gains; before selling in a taxable account, review gains, losses, holding periods, and transaction consequences.
Annual rebalancingStart with the end in mind
“Begin With the End in Mind” means defining the finished portfolio before deciding where the next dollar goes. Your method may fill one bucket at a time or pursue a target allocation across all three; either way, the destination is explicit and the savings is intentional.
Once a year, compare actual balances and years funded with the plan. Direct new savings to an underfunded bucket; during accumulation, the selected method may move excess toward a missing near-term target. Once cash and fixed income cover their intended years, equities growing beyond 15 years alone is no reason to sell. Consider making that check on your birthday so it happens once, on a date you will remember.
Should I invest while paying off debt?
Use the return on the next dollar to decide. Debt interest is a guaranteed cost; investment returns are uncertain; and an employer match is an immediate benefit with its own plan rules.
- Keep every debt current and put out house-on-fire problems first. Protect essential bills and required payments, then address payday loans, overdue debts, and BNPL balances that could trigger severe fees or deferred interest.
- Capture an available employer match. A dollar-for-dollar 401(k), 403(b), or similar match adds another dollar for each dollar you contribute—an immediate 100% increase before market growth. Subject to vesting and plan restrictions, that generally comes before sending an extra dollar to a 25% credit card: the match is more valuable than the interest avoided on that dollar.
- After the full match, compare rates. Paying down a 25% APR balance produces a guaranteed 25% annual interest savings. Investing offers only expected returns. When the debt rate is higher than the planning return you are assuming, direct the next dollar to debt; when it is lower, investing may come first. At a close call, favoring debt recognizes that its savings are guaranteed.
This is a sequencing rule, not permission to ignore debt or automatically maximize retirement contributions. Make required payments, collect the full match available to you, and then rank the remaining use of each extra dollar by its rate.
But what if my stocks go down?
Even when the quoted price falls, you still own the same number of shares. A lower price does not change those shares’ ownership claim on the same businesses and their future profits.
That does not make a downturn painless, and the businesses themselves can change. But as a long-term investor, you accept risk along the way and follow a simple rule: always be buying. Lower prices let each new contribution purchase more shares “on sale” as you build 15+ years of equities in Bucket 3. It is why stocks belong in Bucket 3—long-term growth—with money you do not expect to need for at least five years. Cash and fixed income are there so a falling market does not force you to sell long-term investments to pay near-term expenses during retirement’s drawdown phase.

In Hartford Funds’ review of the ten worst S&P 500 drawdowns since 1960, the average decline took 13 months to reach bottom and another 26 months to regain the old high. Some recovered much faster and some took years longer, which is exactly why Bucket 3 uses a five-plus-year horizon.

Starting a ladder in 2027
If I were nearing retirement and needed to start building a bond ladder in 2027, here is one example: at $5,000 in monthly expenses, three years in Bucket 2 equals $180,000, divided equally among three defined-maturity corporate-bond ETF rungs.

The finish lineThe three buckets
The 2/3/15+ minimum describes this site’s finished starting structure: 2 years of spending in cash, the following 3 in fixed income, and at least 15 more in equities. That is 20 years of initial portfolio-funded expenses for the 5% example, with no upper limit on the equity bucket. The funding sequence may build the long-term bucket first even though you will spend from the buckets in chronological order.
The buckets are numbered and structured to support a systematic withdrawal process in retirement: spend from near-term cash first, replenish it from fixed income, and give long-term equities more time to recover and grow.
The bond ladder is temporary. The default forecast maintains a rolling three-year ladder through retirement year 8. When that year’s rung matures, it is not replaced; the final two rungs mature through year 10. Existing fixed income is not liquidated to force the transition. After the final rung, three years of cash is the normal refill target, not a balance that must always be maintained. Cash can fund spending until it falls below a six-month review trigger.
Refill less during a downturn. Once the ladder is gone, selling enough stocks to rebuild three full years of cash while stocks are down would defeat part of the buffer’s purpose. If the modeled stock mix is at least 20% below its prior peak when a refill is needed, the default rule refills cash only to one year of spending. A later refill outside that downturn can aim for three years again. The stock-price signal works whether or not you use the separate spending guardrail. Six months is a review trigger, not a guaranteed floor: cash can fall lower, and expenses may still require stock sales. The rule limits the size of a discretionary sale; it does not promise to avoid one.
Could you hold less cash? If you are willing to review your plan and refill cash several times a year, you could consider a 12–18 month cash buffer and leave more in Bucket 3 for potential growth. That gives you less of a cushion if markets stay down and may force you to sell investments sooner. The historical results below use the cash targets described above and at most one discretionary refill per year; they do not establish that a smaller buffer or more frequent rebalancing improves outcomes.
The simple case for VT
“I do not know which country, industry, currency, or company will outperform, so I will own the global equity market.”
Inside the equity bucket, VT lets global market capitalization determine the mix of countries, currencies, industries, and companies. Buying a single symbol is simple and effective: there is no need to forecast the next winner because the market weights it for you. Choosing a different equity allocation assumes either that markets are not efficient, that you know better than everyone else, or that you have a specific reason to use another allocation.
A note on taxable accounts: Don’t create a tax bill just to make your portfolio prettier. If existing brokerage holdings have unrealized gains, generally apply the VT default to newly invested dollars and let those holdings remain when appropriate; selling solely to match it could realize capital gains. New contributions can gradually move the overall portfolio toward global market weights, and avoiding an unnecessary taxable event is a perfectly good “specific reason” to differ in the meantime.
For a thoughtful perspective on the shift from U.S.-only investing toward a global fund, read JL Collins on going international and using ETFs. My simple take: if you truly believe in indexing, why not index both domestic and international markets?
Why indexing is powerful
Broad diversification
Own thousands of companies rather than betting your future on a handful of winners.
10,068 stocks as of 7/31/2026.
Lower costs
Avoid sales loads and active-management fees. Low turnover can also reduce costs and potential taxable events.
0.06% expense ratio as of 2/27/2026.
Better odds, fewer forecasts
Own the market instead of trying to select winning companies, sectors, countries, currencies, or investing styles.
Behavioral simplicity
Automate contributions, stay consistent, and reduce the temptation to react to every headline.
What if VT isn’t available?Rebuild broad global coverage with low-cost index funds
VT follows a market-capitalization-weighted index spanning U.S., developed international, and emerging markets. If an employer plan or brokerage menu does not offer VT, look for the lowest-expense-ratio index funds that cover those same broad markets.
Start with the fund menu
Search for “total market” or similarly broad index funds before settling for narrower large-company or actively managed options. Compare expense ratios and confirm which markets each fund actually holds.
Fidelity examples
FSKAX covers the broad U.S. market, while FTIHX covers developed and emerging markets outside the U.S.
Schwab examples
SWTSX covers the broad U.S. market. Pair it with SCHF for developed markets outside the U.S. and SCHE for emerging markets.
Know what changes
These combinations are examples, not exact copies of VT. You choose the U.S./international weights and rebalance them; available share classes, fees, and plan restrictions may differ.
Wait, 2 + 3 + 15 = 20!
“Filling all three buckets with 20 years of expenses implies a 5% initial withdrawal rate, doesn’t it?”
Yes. I worked backward from a 5% initial withdrawal target: 1 ÷ 5% = 20 years of spending the portfolio must fund. In reality, filling the buckets in the recommended approach above lets Bucket 3 grow beyond 15 years while you fill Buckets 2 and 1. The 15 years in Bucket 3 is a minimum for this example, not a ceiling: 2 years of cash and 3 of fixed income are the only buckets that are capped.
Want a lower starting withdrawal target? Fund more years in the long-term bucket. These are arithmetic examples, not promises that any rate will last:
| Initial target | Total years (1 ÷ rate) | Cash | Fixed income | Equities |
|---|---|---|---|---|
| 5.0% | 20.0 | 2 | 3 | 15.0+ |
| 4.5% | 22.2 | 2 | 3 | 17.2+ |
| 4.0% | 25.0 | 2 | 3 | 20.0+ |
| 3.5% | 28.6 | 2 | 3 | 23.6+ |
How much time do you have funded? A $2 million portfolio represents 40 years of $50,000 annual spending, but only about 13.3 years at $150,000. Use the expenses the portfolio actually needs to cover: subtract reliable income such as Social Security or a pension when it begins, not years before the first payment.
Why limit the first two buckets? Bucket 1 avoids most stock-market swings, but cash can lose buying power when interest trails inflation. Bucket 2 covers later needs but has its own interest-rate and inflation risks. That is why this framework aims to keep cash and fixed income near their time-based targets and lets additional savings remain in Bucket 3 for long-term growth.
For a $1.2 million portfolio and $60,000 starting annual spending, the 20-year minimum is $120,000 in cash, $180,000 in fixed income, and $900,000 in equities. The 2/3/15+ split is a planning shortcut, not three independently optimized numbers or proof that 5% is safe. The five years outside equities can give you time before selling stocks in a downturn; it cannot guarantee recovery. Inflation, bond returns, and a long downturn can exhaust those buckets sooner than a simple five-year count suggests.
How Bengen’s number changed
Bill Bengen is the financial planner whose 1994 study became the foundation of the popular “4% rule.” Using historical returns, he found that a 4.15% first-year withdrawal from a 50/50 common-stock and intermediate-Treasury portfolio survived every 30-year period he tested. After year one, the dollar withdrawal rose with inflation rather than resetting to 4.15% of the portfolio each year. In 2006, adding small-company stocks raised his historical figure to about 4.5%. Bengen now describes further research leading to 4.7%, with additional techniques that can reach about 5%. Each step changed the research assumptions. This site does not use Bengen’s portfolio allocation or his fixed inflation-adjusted withdrawal strategy; I am including the research as another historical data point suggesting that, with the right system and a willingness to adapt, a 5% initial target is not unrealistic.
Here, 5% is a starting target for an engaged retiree, not a promise to keep taking the same inflation-adjusted amount for 30 years regardless of what happens. If you’re reading this, you’re no ostrich: periodically ask how many years of spending the portfolio, cash, fixed income, and equities now fund; whether actual lifestyle spending has changed; and whether Social Security or other reliable income has begun to reduce the portfolio’s job. Adjust the spending plan when circumstances materially change and reconsider whether the withdrawal level still fits. You need not watch stock prices every day or tinker with investments after every headline.
What happened in the forecast? I tested every complete 30-year monthly historical window in the site’s Retirement Plan forecast, starting from exactly 2 years in cash, 3 in fixed income, and 15 in equities—the 20-year minimum for this example, without extra equity years. All nine cases use the temporary bond tent: replenish the three-year fixed-income bucket through retirement year 8, then let it wind down through year 10. After the final rung, review cash below six months; refill toward three years normally, or only one year during a 20% stock drawdown. Baseline lifestyle spending rises with the CPI observed in each window. There are no other income sources or new contributions.
Why use 10- and 15-year outside-income starts? This was an arbitrary, conservative starting point. A traditional 65-year-old retiree would only have to wait two years to receive the full Social Security benefit instead of 15. An early retiree at 52 years old could receive their early Social Security benefit (70% of the full amount) after the 10 years scenario below. The full offset covers one-third of ongoing lifestyle spending; the earlier offset is 70% of that amount, or 23⅓% of spending. On a $60,000 starting budget, those are $14,000 and $20,000 a year in starting purchasing power once each begins. Lifestyle spending itself does not fall. The model treats the portfolio as accessible and does not model taxes or account-access restrictions.
The two responses form a 3-by-3 sensitivity table. All nine cases use the cash refill rule above. Moving right changes the timing and size of outside income; moving down increases the share of spending that can be cut temporarily during a stock drawdown. The top-left “ostrich” case assumes neither response.
| Flexible spending cutduring a 20% stockdrawdown | Illustrative outside-income offset | ||
|---|---|---|---|
| None | After 10 years 70% of full; 23⅓% of spending | After 15 years Full; 33⅓% of spending | |
| 0% | 243 of 1,506 (16.1%) Ostrich case | 58 of 1,506 (3.9%) Earlier, smaller income only | 90 of 1,506 (6.0%) Later, full income only |
| 15% | 160 of 1,506 (10.6%) 15% spending guardrail only | 5 of 1,506 (0.3%) 15% guardrail plus earlier income | 16 of 1,506 (1.1%) 15% guardrail plus full income |
| One-third | 72 of 1,506 (4.8%) One-third spending guardrail only | 0 of 1,506 (0.0%) One-third guardrail plus earlier income | 2 of 1,506 (0.1%) One-third guardrail plus full income |
What should I take away from this table? Don’t be an ostrich. The worst results came from sticking your head in the sand and not responding to any pressure on the plan. The table shows the two easiest-to-pull levers for retirees: temporarily reduce spending during a major market downturn, or reduce portfolio withdrawals once Social Security or other outside income begins. Spending flexibility provides immediate relief during a bad market (like not taking the extra vacation) while outside income (like Social Security) reduces the demand on the portfolio. In these historical windows, receiving a smaller amount of income sooner was more helpful than waiting for a larger amount. Combining outside income with even a 15% spending guardrail reduced the historical failure rate from 16.1% to between 0.3% and 1.1%. That does not guarantee the same result in the future, but it shows why a plan that can adapt is more resilient than one that requires the portfolio to fund the same spending through every market.
Past results are not a guarantee of future outcomes. Markets can do things this history has never seen. In this test, 243 windows failed without either response. The earlier, smaller income reduced failures to 58, while the later, full income reduced them to 90: receiving less income sooner helped more stressed sequences than waiting for the larger amount. Combining the earlier income with the one-third spending guardrail produced no failures in this history, which does not mean there is no future risk. A retiree could also return to part-time work during a downturn to reduce portfolio withdrawals until stock prices recover. That would add income rather than cut expenses, and it is not included in these results.
The guardrail requires an actual spending cut. Whenever the scenario’s stock price drops by 20% or more from its previous high, the middle row cuts lifestyle spending by 15% and the bottom row cuts it by one-third until the stock mix recovers to that high. On a $60,000 starting budget, that means spending $51,000 or $40,000 a year while the rule is active, before inflation adjustments. Outside income is a separate offset to what the portfolio must fund; it does not itself reduce lifestyle spending.
The complete windows start from February 1871 through July 1996. The historical series runs through June 2026, so later starts cannot yet provide a full 30-year outcome. Choosing a deeper cut because it improves these historical results does not establish that future households can make that cut or that future markets will behave the same way.
Method: Big ERN’s SWR Toolbox v2.0 monthly cash, 10-year Treasury, S&P 500, world ex-US, and CPI series. Each historical month uses the change in the cash index for cash returns and the change in the CPI index for spending inflation, rather than the site’s default 3% cash return and 3% expense inflation assumptions. The site models equities as a monthly rebalanced 60% U.S./40% international mix, not VT’s actual returns; the 10-year Treasury series stands in for fixed income rather than individual nominal or TIPS ladder maturities. The one-third full offset is a scenario assumption, not a Social Security estimate: replacement rates compare benefits with earnings, not retirement spending. The smaller offset uses 70% of the full amount because the SSA early-retirement formula reduces a worker benefit by 30% when full retirement age is 67 and benefits begin at 62. The model applies that ratio to a round 10-year start for sensitivity analysis; it is not modeling a claiming age. Both offsets rise with each window’s monthly CPI; actual benefits and annual COLAs may differ. Use a personalized benefit estimate to test your own plan. A failure is the first month a required withdrawal cannot be fully funded. Overlapping historical windows are not independent trials or a forecast probability. Taxes, fund fees, and account-level constraints are excluded. Reproduce this analysis.
