How Much Should I Save for Retirement?

The real question is not your savings number — it is your spending plan. Here's how physicians should think about retirement targets, withdrawal rates, and goals that extend well beyond the finish line.

By Sanjay Pamurthy, CFP® | Artham Advisors | June 2026

Quick Answer: The income-replacement rule of thumb — save enough to replace 70–80% of pre-retirement income — was built for average workers, not physicians. Your actual number is your annual retirement spending multiplied by a time-horizon multiple (25× for a 30-year retirement, up to 33× for 45+ years), plus any goals beyond your own spending: college funding, parental support, and legacy giving. Build the spending plan first; the savings math follows directly.

The most common retirement planning mistake starts with the wrong question. Physicians ask "how much do I need?" when the more productive question is "how much will I spend?" Your target portfolio size is derived from your spending — not the other way around. Get the spending plan right first, and the savings math follows directly.

This matters more for physicians than for most people. Income-replacement rules of thumb are designed for the average worker earning $80,000 a year. They are blunt instruments that consistently mislead physicians, whose income is atypically high, whose working years are compressed, and whose financial life involves goals that extend well beyond personal retirement spending.

Start with a Spending Plan, Not a Savings Target

Retirement spending for most physicians is not 70–80% of pre-retirement income — it's whatever your actual retirement lifestyle costs, and for many physicians that's meaningfully less than their peak earning-year spending. The mortgage is often nearly paid off, children have finished college, disability premiums end, and the 20–30% of gross income once earmarked for savings is no longer needed. A physician earning $500,000 and spending $250,000 annually may find retirement spending closer to $150,000–$180,000 — well below what the income-replacement rule would project.

Build a realistic spending plan by category: housing, travel, healthcare (including Medicare gap coverage and long-term care), dining, giving, hobbies, and family support. Run two versions — a baseline and an elevated scenario covering peak travel years. That range becomes your planning target.

Goals Beyond Retirement: The Expenses Most Plans Miss

A plan that only accounts for your own spending is incomplete. Most physicians carry financial obligations and aspirations beyond their personal needs — and these goals carry real price tags that belong in any serious retirement target.

College Funding for Children
A four-year private university education is projected to cost $350,000–$500,000 by 2038–2042 for children born today. For a physician with two or three children, that's $700,000–$1.5 million in future obligations, net of expected aid. A 529 plan funded early is the most tax-efficient vehicle, but its contributions compete directly with retirement savings — integrated planning, not siloed accounts, resolves the tension.

Support for Aging Parents
Physicians are frequently in the "sandwich generation" — supporting children at home while subsidizing aging parents. Parental support of $40,000–$100,000 per year over five to ten years is a significant, often unplanned, retirement drain. Model it explicitly rather than hoping it doesn't materialize.

Charitable Giving and Legacy
Many physicians defer philanthropic intentions during peak earning years. A donor-advised fund (DAF) is a highly tax-efficient vehicle for bunching charitable contributions before retirement — particularly effective in high-income years before the transition. Legacy planning (trusts, estate documents, beneficiary structures) should be integrated with retirement modeling, not treated as a separate exercise.

The 4% Rule — and When Physicians Should Use 3%

The 4% rule — originally articulated by William Bengen and tested extensively since — holds that a portfolio sufficient to sustain a 4% annual withdrawal, adjusted for inflation, has survived every 30-year historical market sequence in U.S. data. The arithmetic is simple: target portfolio = 25× your annual retirement spending. A physician planning to spend $200,000 per year needs roughly $5 million by the 4% rule; $150,000 per year requires $3.75 million.

But the 4% rule was calibrated for a 30-year horizon — roughly age 65 to 95. Physicians who retire at 55, 58, or 60 need their portfolios to last 40–45 years. Research from Kitces.com on time-horizon-adjusted withdrawal rates indicates the safe starting rate declines as the horizon lengthens:

Retirement Age	Time Horizon	Suggested Rate	Portfolio Multiple
50	45+ years	3.0%	33× spending
55	40 years	3.25%	31× spending
60	35 years	3.5%	29× spending
65	30 years	4.0%	25× spending

How That Money Is Invested: Sequence of Returns Risk

The single most underappreciated retirement risk for physicians isn't average investment returns — it's sequence of returns risk: the danger that a market downturn in the first three to five years of retirement can permanently impair a portfolio, even if long-run average returns are fine. Two physicians can retire with identical portfolios and identical 30-year average returns; the one who faces a downturn in year two, forced to sell more shares while prices are down, ends up in a dramatically worse position than the one whose downturn arrives later.

Three practical strategies reduce sequence risk:

FLEXIBLE SPENDING: Reducing withdrawals by 10–15% during a sustained decline dramatically improves long-run outcomes. Physician on FIRE has modeled this extensively — the willingness to adjust spending in bad years is the single most powerful mitigation.

CASH BUFFER: Hold one to two years of expenses in a high-yield savings account and draw from it during downturns rather than selling equities, giving the portfolio time to recover without forced selling.

BOND TENT: Carry a higher bond allocation in the five years before and after retirement, then shift gradually back to equities — reducing the damage a bad early sequence can do during the most vulnerable window.

Bogleheads principle: A simple, low-cost, diversified three-fund portfolio — total U.S. market, international, bonds — managed with discipline will outperform most actively managed alternatives over a full career. The barrier to success is rarely intelligence; it's consistency, starting early, and holding the savings rate through volatility.

Early-retiring physicians — especially those targeting FIRE in their 50s — face the most acute sequence risk and should plan for it explicitly, not hope it resolves on its own.

Second Careers as a Bridge: The Math Is Powerful

Full retirement isn't the only option — for many physicians, it isn't even the most attractive one. A second-career phase involving consulting, expert witness work, medical education, telemedicine, or part-time clinical coverage can dramatically change the math, because every dollar earned in early retirement is a dollar that doesn't need to come from your portfolio. At a 3% withdrawal rate, $80,000 per year of consulting income is equivalent to $2.67 million of additional portfolio — translating directly into either a lower savings target or a higher standard of living.

Physicians have unusually strong consulting market value: expert witness work typically runs $400–$600 per hour, and medical affairs, clinical advisory, or health-tech advisory roles often pay $200–$500 per hour. Many physicians find that 10–15 hours of consulting per week generates $100,000–$200,000 annually with a dramatically reduced stress load versus full-time clinical practice.

Bridge strategy example: A physician who retires from full-time practice at 58 and earns $120,000 per year consulting for six years reduces their portfolio draw to near zero during the highest sequence-of-returns-risk window — then transitions to full retirement at 64 with Social Security approaching. This isn't a compromise. For most physicians, it's a superior plan.

What Savings Rate Do You Actually Need?

Savings rate is the lever that determines when you reach your target portfolio. White Coat Investor recommends 20% of gross income as the minimum for a traditional retirement at 65, and 25–30% for those targeting financial independence before 60. Physician on FIRE's "Live on Half Challenge" illustrates that a 50% net savings rate compresses the path to financial independence to 14–19 years from the start of an attending career.

For physicians who started late — completing training in their 30s — a higher savings rate isn't optional. Someone who begins saving at 35 with a target retirement at 62 has 27 years of compounding; starting at 40 leaves only 22. The difference in required savings rate is significant, and the cost of delay is non-recoverable. Start now, even imperfectly.

Know Your Number. Build the Plan.

Retirement planning for physicians requires more than a savings calculator. It requires integrating your spending plan, your family goals, your tax strategy, your debt, and your investment structure into a single coherent model — your number is your annual retirement spending times your time-horizon multiple, plus education, parental support, and legacy goals, minus expected Social Security, part-time income, or pensions.

We build that plan for physician families every day.

Frequently Asked Questions

It depends entirely on planned spending, not income. A physician spending $150,000 per year in retirement needs roughly $3.75–4.5 million (at a 3.5–4% withdrawal rate). One spending $250,000 needs $6.25–8 million. These numbers shift downward if part-time income bridges the early retirement years, and upward for goals like college funding and parental support.
Immediately. The most common and costly physician mistake is deferring retirement savings during residency and fellowship. Even small contributions to a Roth IRA during training compound to significant sums over a 30–40 year horizon. The first year of attending practice is the second most important moment — contribution capacity surges and structuring decisions made then have the highest long-run impact.
There is no universal answer, but a common framework is 80–90% equities (globally diversified, low-cost index funds) during accumulation years, transitioning toward a "bond tent" of 50–60% equities in the five years before and after retirement, then gradually shifting back to 70–80% equities as sequence-of-returns risk subsides.
This is as much a personal-finance question as a math question. At today's mortgage rates and stock valuations, expected after-tax equity returns are often lower than mortgage interest rates, which favors faster paydown on the surface — but that reduces cash available to invest when markets correct, and there are tax implications to weigh. Mortgage freedom also has real, non-numeric value: it's emotional, reduces required retirement income, and simplifies cash flow. There is no universally correct answer — it depends on your full plan.
