Retiring Early: A Friendly Guide to a Sustainable Plan
Early retirement buys you more time for the people and things you care about, but it also means your savings need to stretch further, often years before Medicare or Social Security show up. A solid plan doesn't start with a magic number. It starts with the life you actually want, translated into a spending plan, a strategy for accessing your money at each stage, and a process for adjusting when life changes. A portfolio balance alone can't tell you if you're ready.
In this guide, we'll walk through how to:
Estimate what your investments actually need to cover
Think about withdrawal rates without treating them as guarantees
Bridge the years before Medicare and Social Security
Coordinate healthcare, taxes, and benefits timing
Prepare for down markets, surprise expenses, and a longer-than-expected retirement
Along the way, we'll follow two hypothetical people: Alex, who retires fully at 50, and Jordan, who eases into part-time work at 58, to see how the timing of income and spending can matter just as much as how much you've saved.
1. Start with the life you want — not just a number
There is a line in the book The Way of the Warrior Kid, by retired Navy SEAL Jocko Willink that states discipline equals freedom. It's a simple idea with real weight, especially today, when social media and same-day shipping make it easy to lose sight of long-term goals in favor of whatever's next.
If early retirement is on your list, the choices you make now shape whether it becomes real. But "retiring early" means different things to different people: walking away from work completely, cutting back to part-time, consulting occasionally, or shifting to something more personally rewarding. There's no universal checklist. You get to define your own target age, lifestyle, and comfort level with future work.
And no, you don't need to be debt-free to retire early. A manageable mortgage can coexist just fine with a sound plan; high-interest consumer debt is a different story. The real question is whether your obligations fit comfortably within the plan, without crowding out the spending that matters most.
Start with three questions
1. Lifestyle — what will everyday life actually cost, including travel, housing, family support, and hobbies?
2. Work — is future income nice to have, or does your plan depend on it?
3. Flexibility — which expenses could you trim if markets, health, or family circumstances take a turn?
If your plan depends on continuing to earn some income, say so explicitly — don't let that assumption quietly hide in the background.
2. Get a clear picture of where you stand
Before mapping the road ahead, take stock of what you have: assets, debts, income, and obligations. Separate money you can actually spend from assets that would first need to be sold, borrowed against, or otherwise converted to cash.
| Category | What to Document |
|---|---|
| Cash & taxable investments | Balances, cost basis, liquidity, intended use |
| Retirement accounts | Types, balances, withdrawal rules, beneficiaries |
| Category | What to Document |
|---|---|
| Property & business interests | Estimated value, debt, costs, realistic path to cash |
| Future income | Social Security, pensions, employment, net rental income |
| Debt | Rates, required payments, payoff dates |
| Family commitments | Education, dependents, caregiving, planned gifts |
| Irregular expenses | Home repairs, vehicles, major travel, big purchases |
Home equity adds to your net worth, but it doesn't pay the electric bill on its own — and rental income should be counted after vacancies, repairs, insurance, taxes, and management costs, not before.
One of the most useful things you can do here: track your actual spending for a full year. That captures the irregular stuff - a new roof, a new car - which is far easier to plan for than to be surprised by.
3. Turn your goals into a real spending plan
Now build the budget, in four buckets:
Essential spending: housing, food, utilities, transportation, required debt payments
Discretionary spending: travel, entertainment, gifts, extras
Healthcare & protection: premiums, medical costs, insurance
Taxes & irregular expenses: income taxes plus a reserve for big-ticket items
Count investment and advisory fees once — either as a drag on returns or as a line-item expense, never both.
Build this in stages, because your numbers will shift: when you stop working, when the mortgage is paid off, when Medicare starts, when Social Security begins. Travel might be front-loaded into your early years, while healthcare or caregiving costs can climb later and offset other savings.
Be consistent about inflation. "Today's dollars" reflects current purchasing power; "future dollars" bake in assumed price increases. At a modest 2.5% annual rate, something that costs $60,000 today runs about $98,300 in 20 years.
A practice worth trying: As we discussed in another paper, test drive your retirement by living on your proposed retirement budget while you're still working. You'll quickly see whether it truly supports the life you want and whether it's missing costs your paycheck or employer benefits currently hide from view. The expense part of this analysis is critical to the plan’s success, and this is one area where the individual needs to be realistic and thorough because an advisor will never be able to truly estimate a client’s spending. It is like going to the doctor and not being fully forthcoming about your symptoms when you are not feeling well.
4. Estimate a savings target — without mistaking it for a promise
Start with what your investments actually need to cover:
Annual portfolio need = spending, taxes, and planned reserves − income from other sources
Be consistent on taxes for both sides of that equation, and if income is counted before tax, spending needs to include the tax bill that comes with it.
A simple way to translate that into a portfolio size: divide your first year's withdrawal by an assumed withdrawal rate.
| Initial Annual Withdrawal | Assumed Rate | Implied Portfolio |
|---|---|---|
| $50,000 | 4.0% | $1,250,000 |
| $50,000 | 3.5% | $1,428,571 |
| $50,000 | 3.0% | $1,666,667 |
These are arithmetic illustrations, not promises. The well-known "4% rule" means withdrawing 4% of your starting portfolio in year one, then adjusting that dollar amount for inflation each year after not 4% of your current balance every year.
How long retirement needs to last matters enormously. Morningstar's The State of Retirement Income: 2025 found that, using a 90% modeled probability of not running out, the highest sustainable starting rate was about 3.9% over 30 years and only 3.3% over 40 years (Morningstar, 2025, pp. 1, 51). Those numbers carry their own assumptions; they're not guarantees or advice tailored to you.
If you're retiring at 50, even a 40-year study only reaches age 90 and this is worth its own conversation. A 3% starting rate can be a useful comparison point but shouldn't be treated as universally "safe."
A year-by-year plan tells you more than a single percentage, since later income like Social Security can lower what you need to withdraw, while healthcare costs, taxes, or big purchases can raise it. For perspective: trimming your annual portfolio need by just $10,000 lowers your target portfolio by roughly $286,000 at a 3.5% rate. Part-time income works differently because it only reduces withdrawals for as long as it lasts.
5. Strengthen your plan before you give notice
Save deliberately
Automate contributions and make sure you're capturing any employer match. Balance retirement-account savings against accessible investments you can tap before you can reach retirement funds penalty-free.
Think through debt carefully
Paying off debt lowers required spending, but the flipside is that using a lot of liquid savings to erase a mortgage can leave you short on cash for healthcare, taxes, or emergencies. Weigh the interest rate, your liquidity needs, and any tax consequences.
Check concentration and fees
Employer stock, a single property, or one concentrated investment can quietly tie your future to a single outcome. Diversifying won't eliminate market losses, but it reduces that concentration risk and while you're at it, review fund expenses and advisory fees (see SEC guidance on diversification and fees). We have seen clients have concentrated positions due to a favored investment holding, but most often due to their employer’s stock. A complicating factor is that people sometimes feel a misplaced loyalty to that stock because they worked for the company for a long period and receiving stock grants and purchasing stock through employee programs helped build their next egg. The lack of diversification can be a huge risk because you can become overly reliant to that single position to fund a retirement and think about how many leading companies remain leading companies over many decades. This is one of the prime reasons we really focus on diversified portfolios to drive retirement security.
Pressure-test big lifestyle decisions
Moving or downsizing can meaningfully change your monthly costs but compare ongoing expenses and real transaction costs before assuming a particular savings figure. Also, moving to a lower tax state might save you some money, but if it takes you away from children, grandchildren and friends, is the tax savings worth the loss of connectivity? These are all things that need to be carefully considered.
6. Build a plan for accessing your money
Having enough money and being able to get to it are two different problems. Under current federal rules, taking money out of most retirement accounts before age 59½ generally triggers an extra 10% tax on top of ordinary income tax, unless an exception applies (see IRS early-distribution guidance). A few of the main bridges:
Cash and taxable investments
No age restrictions. Just remember that selling investments can create a taxable gain, and usually only the gain is taxed, not the full sale amount.
The "rule of 55"
If you separate from an employer during or after the year you turn 55, you may be able to tap that employer's plan penalty-free. It doesn't apply to IRAs, so confirm eligibility and plan rules before rolling money out.
Roth IRA withdrawals and conversions
Contributions generally come out before conversions and earnings, under Roth ordering rules. Converting pretax money to a Roth creates taxable income now, and each conversion carries its own five-year clock for penalty purposes — a useful tool, but not an instant, tax-free bridge (IRS Pub. 590-B, 2025).
Substantially equal periodic payments (SEPPs)
These can unlock penalty-free access, but the rules are strict: payments generally must continue for five years or until 59½, whichever is longer. Changing course improperly can trigger back taxes and interest.
Map which accounts fund which years:
| Stage | Key Decision |
|---|---|
| Retirement to age 59½ | Identify accessible assets, confirm any exception applies |
| 59½ to Medicare eligibility | Coordinate withdrawals, taxes, and coverage |
| Medicare eligibility to claiming Social Security | Budget Medicare costs, fund any delay |
| After Social Security begins | Recalculate remaining portfolio need |
| Later retirement | Factor in required distributions and changing care needs |
Also confirm your required minimum distribution rules based on birth year and account type as part of the tax plan.
7. Price out healthcare before you pick a date
Before Medicare eligibility, compare your options: spousal coverage, retiree benefits, COBRA, and the individual Marketplace. Losing job-based coverage typically opens a Marketplace special enrollment window.
COBRA usually offers up to 18 months of continued coverage but you should expect to pay the full premium plus an administrative fee, up to about 102% of the plan's cost.
Get actual quotes for your household's ages, location, income, prescriptions, and providers. Compare annual premiums after any assistance, expected deductibles/copays/coinsurance, the out-of-pocket maximum and exclusions, provider networks and prescription coverage, and anything not covered like dental or vision.
A note for 2026: the temporary expansion of premium tax credit eligibility above 400% of the federal poverty level applied through 2025; for 2026, that income limit is generally back in effect. There's also no cap on repaying excess advance premium tax credits after 2025, and you'd owe back the full excess. That makes coordinating income, investment sales, and any Roth conversions especially important.
Medicare needs its own line item too. For 2026, the standard Part B premium is $202.90/month per person, with a $283 annual deductible and this is before additional premiums, cost-sharing, or income-related adjustments. Review enrollment timing before 65, since COBRA and retiree coverage interact with Medicare differently than active employment coverage. And separately, plan for long-term care because Medicare generally doesn't cover ongoing custodial care.
Medical care is often the second largest retiree expense after taxes, and it is best to plan for how medical expenses will be covered before quitting a job and giving up employer-provided benefits.
8. Two paths to early retirement, side by side
These are hypothetical illustrations, not recommendations or proof that either starting portfolio is "enough." Both people are single, start in 2026, and figures are in 2026 dollars. Shared assumptions: planning to age 95, 2.5% inflation, a 5.5% gross investment return (5.0% net of a 0.5% fee, ~2.44% real), $60,000 annual spending ($42,000 living, $12,000 healthcare, $6,000 taxes), and $30,000 gross Social Security starting at 67, with no pension, inheritance, or other windfalls.
Alex — retires completely at 50
Alex starts with $1.8 million ($650,000 taxable, $1.15 million retirement). Investments need to cover the full $60,000 each year — about 3.33% of the starting balance — until Social Security begins at 67, when the need drops to $30,000. The big challenges: a 45-year horizon, the pre-Medicare years, and getting money out before 59½.
Jordan — shifts to part-time work at 58
Jordan starts with $1.3 million ($250,000 taxable, $1.05 million retirement). Part-time income of $25,000/year through age 62 means investments only need to cover $35,000 — about 2.69% of the starting balance. At 63, work ends and withdrawals jump to $60,000; at 67, Social Security brings that back down to $30,000. Jordan's challenge is different: a low starting withdrawal rate can mask the jump that's coming once the part-time income stops.
| Stage | Key Decision |
|---|---|
| Retirement to age 59½ | Identify accessible assets, confirm any exception applies |
| 59½ to Medicare eligibility | Coordinate withdrawals, taxes, and coverage |
| Medicare eligibility to claiming Social Security | Budget Medicare costs, fund any delay |
| After Social Security begins | Recalculate remaining portfolio need |
| Later retirement | Factor in required distributions and changing care needs |
Jordan's five years of part-time work reduce direct withdrawals by $125,000 before investment effects, but that benefit disappears the moment the work goes away. Alex's larger starting portfolio buys more runway without employment, but stays more sensitive to long-run returns. Neither constant-return scenario tells you a probability of success; they simply show why the timing of income and withdrawals matters as much as the total saved.
9. Guard against investment and withdrawal risk
Losses early in retirement can do outsized damage, because you're selling assets to fund withdrawals at the same time the market is down, and this is known as sequence-of-returns risk. Picture two $100,000 portfolios, each withdrawing $10,000 at year-end:
| Return Sequence | End of Year One | End of Year Two |
|---|---|---|
| −20%, then +25% | $70,000 | $77,500 |
| +25%, then −20% | $115,000 | $82,000 |
Same two returns, different order, different ending balance, all because withdrawals happen along the way. (This simplified example ignores taxes, fees, and inflation.)
Pick a withdrawal approach that matches your flexibility: inflation-adjusted dollar withdrawals offer predictable income but can strain a falling portfolio; a percentage of current assets adjusts automatically but produces variable income; and guardrails set pre-agreed conditions for raising or cutting spending. Decide your adjustment rules before a downturn hits — maybe that means postponing a big trip or pausing an inflation bump after a rough year.
Cash reserves reduce the pressure to sell investments during a downturn, but too much cash drags on long-term growth and loses ground to inflation — size your reserve around near-term spending and other income. And don't lump all "guaranteed" income together: pensions, rental income, and annuities each carry their own considerations around inflation protection, survivor benefits, fees, liquidity, and counterparty risk.
10. Coordinate taxes and Social Security
The year with the lowest tax bill isn't always the year that produces the best lifetime outcome. Compare how you draw from taxable, tax-deferred, and Roth accounts — a large sale or conversion can ripple into current taxes, healthcare assistance, future balances, and required distributions down the road. Revisit this every year rather than assuming retirement automatically drops you into a lower bracket.
Stopping work and claiming Social Security are separate decisions. If you were born in 1960 or later, full retirement age is 67. Claim at 62 and you'll generally get about 70% of your full benefit; wait until 70 and you'll get about 124%, before other adjustments. Waiting means a bigger monthly check, but you need to fund the years in between, so weigh health, family longevity, available assets, and household needs. If you're married, compare spousal and survivor outcomes too, since those rules differ from your own retirement benefit.
Update your Social Security estimate using your actual planned work-stop date. Your benefit is based on your highest 35 years of earnings, so stopping early can leave zero or low-earning years in that calculation.
11. Stress-test the plan
| Risk to Test | Potential Effect | Response to Evaluate |
|---|---|---|
| Market decline near retirement | Higher withdrawals vs. remaining assets | Trim discretionary spending or delay retirement |
| Prolonged inflation | Spending grows faster than planned | Revisit budget and priorities |
| Lower returns over time | Reduced ability to sustain withdrawals | Save more, spend less, or work longer |
| Loss of part-time/rental income | Bigger portfolio withdrawals | Test the plan without that income |
| Major healthcare/care costs | Large unplanned withdrawals | Review reserves, insurance, care options |
| Outliving the plan horizon | More years to fund | Extend projections, revisit lifetime income |
| Widowhood, divorce, caregiving | Shifts in income, taxes, expenses | Rebuild the household plan promptly |
| Tax or benefit rule changes | Less spendable income | Update assumptions and strategy |
Monte Carlo analysis can test hundreds of simulated market paths, but it's only as good as its return, inflation, spending, and longevity assumptions. A "90% success rate" means 90% of the simulated paths met the model's definition of success — not a 90% real-world guarantee. Ask how bad the unsuccessful outcomes are, when trouble tends to show up, and how much spending flexibility the model assumes.
12. Life after full-time work
Money is only part of the picture. Talk with your spouse or partner about expectations, think about where your social connections will come from, and consider how you'll spend your time among family, interests, work, and community. Communicating your needs is vital for future success. Clear expectations prevent financial friction.
Before you leave your job, make sure:
Your budget has been tested against real spending
Healthcare coverage, dates, and costs are mapped out
You know which accounts fund which years
Taxes, fees, and irregular expenses are accounted for
Social Security estimates reflect your real work history
You've thought through the tough scenarios
You and your household agree on contingency moves
Beneficiaries and estate documents are current
You've set a date for your annual review
Check in sooner if markets move sharply, your health changes, or your family or job situation shifts.
Conclusion
Early retirement isn't a one-time decision — it's an ongoing commitment. How well it works depends on your spending, how accessible your assets are, healthcare, taxes, the timing of your income, and your ability to adjust when life changes.
Discipline today can buy you real freedom tomorrow. The goal isn't a perfect prediction — it's a plan built on assumptions you understand, limits you're aware of, and a clear sense of how you'll adapt.
On a final note, we discussed many of the important financial considerations for retiring early. There are also social and mental health issues that are very important to consider. Retirees often report that they felt a loss of purpose after they retired. It is important to not only know how you are going to finance retirement but also know what you are going to do with your time to stay vibrant and engaged. This will mean different things to different people, but it all falls under the heading of “a life worth living”!
